SUMMARY OF THE PROXY STATEMENT

A summary of some of the information contained in this Proxy Statement for the 2017 Annual Meeting of Stockholders (2017 Annual Meeting) is set forth on the following pages. Each summary does not contain all of the information that a stockholder should consider before voting. The entire Proxy Statement should be read before doing so. The Company's 2016 Annual Report is its Annual Report on Form 10-K for the year ended December 31, 2016, which has been filed with the Securities and Exchange Commission.


Matters to be Voted on at the Meeting

Proposal #1 :	The election of seven Directors for one-year terms. The table below contains a summary of some of the information about the nominees for director. More detailed information can be found below under the heading Election of Directors (Proposal 1) at Page 4.

Nominees		Current Position	Age	Occupation	Board Committee	Director Since
Marian M. Davenport		Director	63	Executive Director, Genesys Works — Houston	Corporate Governance Compensation	2014
Maarten D. Hemsley		Director	67	Founder, Chairman and President of New England Center for Arts & Technology, Inc.	Audit Corporate Governance	1998
Raymond F. Messer		N/A	69	Director of Design-Build and Senior Principal, Walter P Moore	N/A	N/A
Charles R. Patton		Director	57	Executive Vice President — External Affairs of American Electric Power (AEP)	Compensation	2013
Richard O. Schaum		Director	70	General Manager, 3rd Horizon Associates LLC	Audit Compensation	2010
Milton L. Scott		Director Chairman	60	Chairman and Chief Executive Officer of the Tagos Group, LLC	Audit Corporate Governance	2005
Paul J. Varello		Director	73	Chief Executive Officer of the Company	N/A	2014

Proposal #2:	To approve the adoption by the Board of an amendment of Article IV of the Company's charter to increase the authorized shares from 28 million shares to 38 million shares, a 36% increase.

	At February 28, 2017, the Company had approximately 25.1 million shares of common stock outstanding or reserved for issuance under the Company's Stock Incentive Plan, approximately 90% of the total number of shares currently authorized for issuance, leaving approximately 2.8 million shares available for issuance. This limits the Company's flexibility if shares are needed for raising funds, for acquisitions, or for other, general corporate purposes such as the recently-announced acquisition of Tealstone Construction and new anticipated financing . If the amendment is approved, the Company will have more than 12 million shares available for issuance for these purposes.

	The Board of Directors believes that an increase in the number of authorized shares is advisable so that the Company will have enough shares to pursue an acquisition strategy, to raise capital, and for other corporate purposes.

Proxy Statement Summary Page I


		More information about this amendment can be found below under the heading Amendment of Article IV of the Certificate of Incorporation (Proposal 2) on Page 10.

	*Proposal #3:*	To approve the adoption by the Board of an amendment of Article VI of the Company's charter to provide for the removal of directors without cause.

		Under the current charter, the Company's directors may only be removed for cause which is permitted by Delaware law, but only for companies that have a board of classified directors. The Company's directors will cease to be classified at the 2017 Annual Meeting. Accordingly, the Board has voted to amend the charter to conform it to Delaware law. Whether or not stockholders approve the amendment, directors of the Company may be removed with or without cause from and after the 2017 Annual Meeting.

		More information about this amendment can be found below under the heading Amendment of Article VI of the Certificate of Incorporation (Proposal 3) on Page 10.

	*Proposal #4:*	Ratification of the selection of Grant Thornton LLP as the Company's independent registered public accounting firm for 2017. Grant Thornton was the Company's firm of independent auditors for 2016. More information about Grant Thornton and their fees can be found below under the heading Information About Audit Fees & Audit Services on Page 38.

	*Proposal #5:*	Advisory approval of the compensation of the Company's named executive officers. Information about the compensation of executives can be found in the summary below and under the heading Executive Compensation on Page 24.

	*Proposal #6:*	Advisory selection of the frequency of holding stockholder advisory votes on executive compensation. The Company recommends annual votes, the same recommendation the Company made in 2011. Information about the frequency of say-on-pay votes can be found below under the heading The Frequency of the Vote on Executive Compensation (an advisory vote) ( Proposal 6) on Page 12.

	o	No director has entered into any related-party transaction with the Company.

	o	Directors are expected to hold shares of the Company's common stock with an acquisition value equal to five times their annual retainer.

PROXY STATEMENT

FOR THE 2017 ANNUAL MEETING OF STOCKHOLDERS

GENERAL INFORMATION

In this Proxy Statement, Sterling Construction Company, Inc. is sometimes referred to as the Company, and the Board of Directors of the Company is sometimes referred to as the Board. The Company is making this Proxy Statement, the form of proxy, and the Company's 2016 Annual Report on Form 10-K available to stockholders starting on March 17 , 20 17 in connection with the solicitation of proxies by the Board for the 2017 Annual Meeting of Stockholders. The Annual Meeting will be held on Friday, April 28, 2017 at 8:30 a.m. local time at the Company's headquarters office at 1800 Hughes Landing Boulevard — Suite 250, The Woodlands, Texas 77380.

On March 17 , 2017, the Company mailed a Notice of Internet Availability of Proxy Materials (the Availability Notice) to stockholders of record on February 28, 2017 (the Record Date) and posted the proxy materials on the Company's website:

www.STRLco.com

as well as on the website provided in the Availability Notice:

http://www.astproxyportal.com/ast/04770

The Company is sending the Availability Notice to all stockholders of record instead of mailing them a printed set of the proxy materials to save postage and paper. As stated in the Availability Notice, if you wish to obtain a printed set of the proxy materials, you can do so without charge by requesting a copy either by telephone, by e-mail, or through either of the websites listed above, all as described in the Availability Notice.

On or about April 1, 2017, the Company plans to mail a second Availability Notice to stockholders that will be accompanied by a proxy card on which you can indicate how you wish your shares to be voted.

The Record Date . The Company has established February 28, 2017 as the Record Date. The persons or entities whose names appear on the records of the Company on that date as holders of the Company's common stock are entitled to notice of the Annual Meeting and to vote at the Annual Meeting, or at any adjournment of the meeting. On the Record Date, there were 25,051,045 shares of the Company's common stock outstanding.

Methods of Voting . As a holder of record of common stock of the Company on the Record Date, you may vote your shares either by coming to the Annual Meeting and voting in person, or by appointing someone to vote your shares for you by giving that person a proxy.

Voting in Person . To vote your shares in person, come to the meeting at the date, time and address set forth above in the Notice of the 2017 Annual Meeting, and you will be given a ballot on which you can vote your shares on each of the proposals.

However, if your shares are held for you in the name of your broker, bank or other nominee, evidence of your stock ownership on the record date, February 28, 2017 (such as a current letter from your broker, bank or other nominee, or a photocopy of your brokerage or other account statement for February 2017) must be presented at the meeting in order for you to vote your shares in person.

- 1 -

Voting by Proxy . In this Proxy Statement, you are being asked to appoint each of Milton L. Scott, the Chairman of the Board of Directors; Ronald A. Ballschmiede, the Company's Chief Financial Officer; and Roger M. Barzun, the Company's General Counsel, as your proxy to vote your shares in the way you direct, both at the Annual Meeting and at any adjournment of the meeting. Stockholders have the option to vote by proxy in three ways, all of them described in the Availability Notice:

Via the Internet: You may vote via the Internet by following the instructions in the Availability Notice.

By Telephone : You may vote by telephone by calling toll-free 1-800-PROXIES (1-800-776-9437) in the United States, or 1-718-921-8500 from a foreign country using a touch-tone telephone, and by following the instructions given to you. You should have your proxy card with you when you make the call so that you can provide the numbers found on your proxy card when asked to do so.

By Mail : You may vote by mail by obtaining a printed copy of the proxy card in the manner described in the Availability Notice. You may then complete, sign, and date the proxy card and mail it to the Company in the envelope that will have been provided to you with the proxy card.

If your shares are held in the name of a bank, a broker or by another nominee holder of record, please refer to the information provided to you by the nominee about your voting options.

If you vote by proxy, your shares will be voted as you direct if —

Your proxy is properly completed;

Your proxy is received before the Annual Meeting; and

Your proxy is not revoked by you before the voting.

If you do not specify on your proxy how you want your shares voted, they will be voted in the following ways:

FOR

the election of the seven nominees for a term of one year (Proposal 1).

FOR

the amendment of Article IV of the Company's Certificate of Incorporation to increase the Company's authorized shares from 28 million to 38 million (Proposal 2).

FOR

the amendment of Article VI of the Company's Certificate of Incorporation to provide for the removal of directors without cause (Proposal 3).

FOR

the ratification of the selection of Grant Thornton LLP as the Company's independent registered public accounting firm for 2017 (Proposal 4).

FOR

the approval of the compensation of the Company's named executive officers as set forth in this Proxy Statement (Proposal 5) (an advisory vote).

FOR

" every one (1) year" as the frequency for the Company to hold a stockholder vote on executive compensation (Proposal 6) (an advisory vote).

The Board does not know of any other proposal that will be presented for consideration at the Annual Meeting.

- 2 -

Revocation of a Proxy . You may revoke a proxy you have already given in any one of the following three ways:

By sending to the Secretary of the Company, at the Company's address set forth above, a written statement that you wish to revoke your proxy;

By submitting another proxy dated later than a previous proxy; or

By attending the Annual Meeting in person and notifying the chair of the meeting that you wish to vote in person.

Quorum, Vote Required & Method of Counting

The Quorum for the Meeting . A quorum must be present in order to hold the Annual Meeting. A quorum consists of the holders of a majority of the shares of outstanding common stock who are present in person or represented by proxy at the meeting and entitled to vote. Each share of common stock entitles the record holder to one vote on each of the matters to be voted on at the Annual Meeting. When shares are held in "street" name, meaning held by a bank, broker or other nominee, and the nominee indicates on its proxy that because it has not received directions on how to vote the shares, or it does not have the discretionary authority to vote the shares on a particular proposal, it is referred to as a broker non-vote.

Vote Required & Method of Counting .

	Proposal 1.		To be elected a director, a nominee must receive more votes for his or her election than against it. Because the election of a nominee does not require a minimum number of votes, abstentions and broker non-votes will have no effect on the voting for the election of directors.

	Proposals 2 & 3.		The approval of the two amendments of the Company's Certificate of Incorporation requires the affirmative vote of the holders of a majority of the outstanding shares of common stock of the Company. As a result, an abstention and broker non-vote will have the affect of a vote against the proposal.

	Proposal 4.		The ratification of the selection of Grant Thornton LLP as the Company's independent registered public accounting firm for 2017 requires the affirmative vote of the holders of a majority of the shares of common stock who are present in person or represented by proxy at the Annual Meeting and who are entitled to vote on that proposal. Abstentions will have the effect of votes against the proposal. Brokers are entitled to vote on this proposal in the absence of direction on how to vote the shares from their beneficial holders.

			See also the information below under the heading Ratification of the Selection of the Independent Registered Public Accounting Firm (Proposal 4) for the effect of your vote on this proposal.

	Proposals 5 & 6.		The advisory vote to approve the compensation of the named executive officers and to select the frequency with which the Company should hold advisory votes on executive compensation also requires the affirmative vote of the holders of a majority of the shares of common stock who are present in person or represented by proxy at the Annual Meeting and who are entitled to vote on that proposal. Abstentions will have the effect of votes against the proposal, but broker non-votes will not be counted as, by definition, they are not entitled to vote.

- 3 -

The Solicitation of Proxies & Expenses . In addition to the solicitation of proxies by means of this Proxy Statement, directors, officers and employees of the Company and a third-party solicitation agent may solicit proxies using personal interviews, telephone calls, facsimile transmissions and e-mails. The cost of the proxy solicitation agent retained by the Company, Georgeson Inc., will be borne by the Company and is anticipated to be no more than $10,000 plus reimbursement of out-of-pocket expenses. The Company will request banks, brokerage houses and other custodians, nominees and fiduciaries to solicit votes from their customers who are beneficial owners, but not record holders, of common stock, and to forward or make available proxy solicitation materials to those beneficial owners. The Company will reimburse them for the reasonable out-of-pocket expenses they incur in doing so, and will pay the expenses of printing and mailing this Proxy Statement, the form of proxy, the Availability Notice, the Company's 2016 Annual Report on Form 10-K, and any other solicitation materials.

The 2016 Annual Report . A copy of the Company's Annual Report on Form 10-K for the year ended December 31, 2016, which has been filed with the Securities and Exchange Commission (SEC) contains financial statements and other information of interest to stockholders. Stockholders may obtain a copy of the 2016 Annual Report in the same manner as they may obtain a copy of the other proxy solicitation materials.

ELECTION OF DIRECTORS (Proposal 1)

Term of Office & Declassification of Directors . With the 2017 Annual Meeting, the process of declassifying directors that was started at the 2015 Annual Meeting is complete. As a result, nominees that are elected will serve a one-year term. The Bylaws of the Company permit the Board to determine from time to time the number of directors serving on the Board. The Board has set the size of the Board at seven directors.

To be elected, a director must receive more votes for his or her election than against it.

the board of directors recommends that stockholders vote for each director nominee

The Nominees; Independence .

Each of the nominees listed below has been nominated by the independent directors of the Board and has stated a willingness to serve if elected. If any nominee is unable to serve, the proxy holders may vote for a substitute nominee. The Board has no reason to believe that any of the nominees will be unable to serve.

A proxy cannot be voted by the proxy holders for more persons than the number of nominees named in this Proxy Statement. Information about the number of shares of common stock of the Company owned by the nominees can be found below under the heading Stock Ownership Information .

AMENDMENT OF ARTICLE IV OF THE CERTIFICATE OF INCORPORATION (Proposal 2)

Adoption of the Amendment . On November 4, 2016, the Board of Directors adopted, subject to the approval of the stockholders, an amendment of Section 4.1(b) of Article IV of the Company's Certificate of Incorporation (charter) to increase the number of shares of common stock that the Company is authorized to issue from 28 million shares to 38 million shares. In accordance with the Delaware General Corporation Law (DGCL), the Board has declared the amendment to be advisable.

The amended Section 4.1(b) reads as follows:

[4.1] "(b) The number of shares of Common Stock that the Corporation has authority to issue is thirty-eight million (38,000,000) with a par value of one cent ($0.01) per share."

Reasons for the Amendment . At February 28, 2017, the Company had approximately 25 million shares of common stock outstanding which includes the shares reserved for issuance under the Company's Stock Incentive Plan. With approximately 90% of the total number of shares currently authorized for issuance outstanding or reserved, only approximately 2.8 million shares remain available for issuance. This limits the Company's flexibility if shares are needed for raising funds, for acquisitions, or for other, general corporate purposes such as the recently-announced acquisition of Tealstone Construction and new anticipated financing . If the amendment is approved, the Company will have more than 12 million shares available for issuance for these purposes. The Board of Directors believes that an increase in the number of authorized shares is advisable so that the Company will have enough shares to pursue an acquisition strategy, to raise capital, and for other corporate purposes.

The Company has grown through acquisitions and seeks to have a portion of the acquisition purchase price payable in shares of common stock so that the seller has an incentive to support and contribute to the success of the Company after the acquisition, whether or not the seller remains part of the Company.

Effect of the Issuance of Newly-Authorized Shares . The issuance by the Company of additional shares of common stock would have the effect of diluting the percentage ownership of current stockholders of the Company. In addition, in the absence of a proportionate increase in the Company’s earnings and book value, an increase in the number of outstanding shares of common stock would dilute the earnings per share and book value per share of outstanding shares of common stock.

The Board of Directors recommends that stockholders vote for the approval of the Amendment of Section 4.1( b ) of Article IV of the Certificate of Incorporation

AMENDMENT OF ARTICLE VI OF THE CERTIFICATE OF INCORPORATION (Proposal 3)

Adoption of the Amendment . Under the Delaware General Corporation Law (DGCL), only a board with classified directors can provide that directors may only be removed for cause, and Section 6.4 ( Removal of Directors ) of Article VI of the Company's charter contains that provision. Until the 2017 Annual Meeting, the Company had classified directors. At the 2014 Annual Meeting, stockholders approved an amendment to the charter to phase out the classified board over three years beginning with the 2015 Annual Meeting. As a result, at the 2017 Annual Meeting, the Board's directors will no longer be classified.

- 10 -

Therefore, in order to bring the charter into compliance with Delaware law, on November 4, 2016, the Board voted to amend Section 6.4 to eliminate the requirement for cause in the removal of directors. The amended section reads as follows:

"6.4 Removal of Directors . Subject to the rights of the holders of any outstanding series of Preferred Stock, any director or the entire Board of Directors may be removed from office at any time by the affirmative vote of the holders of a majority of the combined voting power of the then outstanding shares of capital stock of all classes and series of the Corporation entitled to vote generally in the election of directors, voting together as a single class."

If the amendment is not approved, Section 6.4 will remain out of compliance with Delaware law, but directors may nevertheless be removed with or without cause.

Pursuant to the DGCL, the Board of Directors has declared the amendment of Section 6.4 of Article VI to be advisable.

Required Approval and Effective Date of the Charter Amendments in Proposals 2 and 3 . The approval of an amendment to the charter requires the affirmative vote of the holders of at least a majority of the Company's outstanding shares of common stock. At February 28, 2017 the record date for the 2017 Annual Meeting, there were 25,051,045 shares of common stock outstanding. An amendment approved by stockholders will become effective when it is filed with the Secretary of State of the State of Delaware, which the Company intends to do promptly after the 2017 Annual Meeting. However, in accordance with the DGCL, notwithstanding the authorization of the proposed amendments by the stockholders, the Board is permitted to abandon either or both amendments without further action by the stockholders, but it has no intention of doing so.

The Board of Directors recommends that stockholders vote for the approval of the Amendment of Section 6.4 of Article VI of the Certificate of Incorporation

RATIFICATION OF THE SELECTION OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (Proposal 4)

Pursuant to its charter, the Audit Committee is responsible for the appointment of the Company's independent registered public accounting firm. The Audit Committee has selected Grant Thornton LLP to perform the audit of the Company's 2017 financial statements. Grant Thornton was also the Company's 2016 independent registered public accounting firm.

The Audit Committee may select a different independent registered public accounting firm at any time during the year if it determines that to do so would be in the best interests of the Company and its stockholders. The Board is asking stockholders to ratify the selection of Grant Thornton as a matter of good corporate practice, although ratification is not required by law or by the Company's Bylaws, and the vote is not binding on the Audit Committee. There is information about Grant Thornton's fees below under the heading Information About Audit Fees & Audit Services .

The ratification of the selection of Grant Thornton requires the affirmative vote of the holders of a majority of shares of common stock present in person or represented by proxy at the meeting and who are entitled to vote on this proposal.

the Board of Directors recommends that stockholders vote for the ratification of the selection of Grant Thornton LLP

APPROVAL OF THE COMPANY’S NAMED EXECUTIVE OFFICER COMPENSATION FOR 2016 (an advisory vote) (Proposal 5)

Current SEC regulations require the Company to solicit an advisory stockholder vote on the compensation of the executive officers of the Company who are listed below in the section entitled The Executive Officers under heading Executive Compensation . The advisory vote, as described below, is commonly referred to as say-on-pay. The vote is not binding on the Company.

At the 2016 Annual Meeting, the holders of common stock present in person or represented by proxy at the meeting and who were entitled to vote on the Company's 2015 executive compensation voted as follows:

Number of Shares Entitled to Vote	Voted For	Voted Against	Abstained
14,586,623	13,640,928 (93.5%)	509,528 (3.3%)	436,167 (3.2%)

In determining how to vote on the Company's 2016 executive compensation, stockholders should take into account all of the disclosures in this Proxy Statement that relate to the compensation of executives. That information includes a discussion and tables that are found below under the heading Executive Compensation , as well as an explanation of why and how the types and levels of executive compensation were determined.

In the event that stockholders do not approve executive compensation, the Compensation Committee of the Board will review its decisions on compensation structure and levels, as well as the comparability of the executives' compensation to that of a peer group of companies, before deciding whether to make any changes in the compensation of one or more of the executives. The affirmative vote of the holders of a majority of the shares of common stock who are present in person or represented by proxy at the Annual Meeting and who are entitled to vote on this proposal is required to approve executive compensation.

The Board of Directors recommends that stockholders vote for the approval of

named executive officer compensation pursuant to the following resolution:

Resolved , that the compensation paid to the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion set forth below under the heading Executive Compensation, is hereby approved on a non-binding, advisory basis.

THE FREQUENCY OF THE VOTE ON EXECUTIVE COMPENSATION (an advisory vote) (Proposal 6)

In addition to the approval of executive compensation, current SEC regulations also require the Company to solicit a stockholder vote on the frequency with which the Company should conduct a vote on executive compensation. The vote is commonly referred to as say-on-frequency. At a minimum, the vote on executive compensation must be held at least every three years, and the vote to select the frequency of voting on executive compensation must be held every six years. Stockholders may vote to hold the vote on executive compensation each year, every two years, or every three years, or they may abstain from voting. It should be noted that stockholders are not voting to approve or disapprove the Company's frequency recommendation, but will vote on which of the three frequency choices they prefer. The vote is advisory in nature and therefore does not bind the Company. At the 2011 Annual Meeting, stockholders voted as follows for the frequency of executive compensation votes:

Every One Year	Every Two Years	Every Three Years	Abstained
11,232,700 (92.2%)	20,223 (0.2%)	869,492 (7.1%)	57,379 (0.5%)

- 12 -

In accordance with the 2011 vote, and as the Board recommended at the time, the Company has held say-on-pay votes annually. The next advisory vote on say-on-pay after the 2017 Annual Meeting will depend on the outcome of the say-on-frequency vote at the 2017 Annual Meeting. The Company believes that a vote every year will enable the Compensation Committee to take into account stockholders' approval or disapproval of executive compensation prior to renegotiating any new compensation arrangements.

In the event that stockholders elect to hold the vote on executive compensation every two or three years, the Board will honor that determination. The affirmative vote of the holders of a majority of the shares of common stock represented and entitled to vote at the Annual Meeting is required to select the frequency of stockholder votes on executive compensation.

the board recommends that stockholders vote " for every one (1) year " as the frequency for holding a stockholder vote on executive compensation

THE BOARD OF DIRECTORS

Communicating with the Board . Stockholders and other interested parties may communicate with the whole Board, the Chairman of the Board, or with any independent director by sending the communication as follows:

By U.S. Mail:

℅ The Secretary

Sterling Construction Company, Inc.

1800 Hughes Landing Blvd. — Suite 250

The Woodlands, TX 77380

By E-mail to the Secretary at: Reports@Lighthouse-Services.com

The Secretary will give the communication to the directors when received unless it is frivolous. If the communication is voluminous, the Secretary will summarize it and furnish the summary to the Board.

Board Governance .

The Board has adopted a set of governance guidelines, some of which are referred to elsewhere in this Proxy Statement. The full set of Board Governance Guidelines can be found on the Company's website, www.STRLco.com, on the Investor Relations page under Corporate Governance.

Independence . The Board is currently made up of six directors, five of whom are independent. All members of the standing committees of the Board are independent directors as required by the Board's Governance Guidelines. Raymond F. Messer, who is a nominee but not an incumbent director, if elected, will also qualify as an independent director. Mr. Varello, Chief Executive Officer of the Company, is the only director who is not considered independent because he is an employee of the Company.

Leadership Structure . For the short period between February 1 and March 9, 2015, Mr. Varello was the Company's Chairman of the Board and acting Chief Executive Officer. As a result of his election as Chief Executive Officer on a more permanent basis and his execution of a three-year employment agreement with the Company, Mr. Varello resigned as Chairman of the Board. Milton L. Scott, who is the Chair of the Audit Committee, was elected Chairman in his place. The Company believes that the separation of the roles of Chairman and Chief Executive Officer, as required by the Board Governance Guidelines, is appropriate in order to enhance the independence of the Board. It separates the operational leadership role of the chief executive from the fiduciary leadership role of the Board.

- 13 -

Declassification of Directors . As described above under the heading Election of Directors (Proposal 1) , the process of phasing out the classification of directors is complete so that at the 2017 Annual Meeting, all director terms of office are for one year.

Election of Directors by Majority Vote . In order to be elected a director, a nominee must receive more votes for his or her election than against it, which is commonly referred to as a majority vote. Because a director is elected for a specified term and until his or her successor is elected and qualified, an incumbent director who is nominated for re-election, but fails to receive a majority vote, would remain a director because no successor had been elected. To cure this problem, each incumbent director, as a condition to being nominated for re-election, must, in advance of the Annual Meeting, submit a resignation that becomes effective if he or she does not receive the required vote, and if the Board accepts the resignation. Before the Board makes a determination on accepting or rejecting the resignation, the Corporate Governance & Nominating Committee considers the matter and makes a recommendation to the Board. Each of the nominees has furnished the Board with the required contingent resignation.

Directors' Attendance at Meetings in 2016 . During 2016, the Board held 20 meetings; the Audit Committee held seven meetings; the Compensation Committee held five meetings; and the Corporate Governance & Nominating Committee held five meetings. The meetings were held in person or by conference telephone call. During 2016, each incumbent director attended, in the aggregate, at lea st 97. 3% of the meetings of the Board and of the committees on which he or she served. All directors attended the 2016 Annual Meeting in person. The Company's policy is to schedule Annual Meetings to coincide with a regular Board meeting so that directors can attend the Annual Meeting without the Company incurring the extra travel and related expenses of a separate meeting.

Stock Ownership Guidelines & Policies .

Hedging of Company Stock. Directors, executive officers, officers of the Company's majority-owned subsidiaries, as well as any employee of the Company or its subsidiaries to whom the Company has awarded shares of common stock, are prohibited from hedging the value of their shares, however acquired.

Pledging Shares & Share Retention . This policy prohibits officers from selling or pledging their shares of the Company's stock if, after giving effect to the sale or pledge, the market value of the number of unpledged shares then held by the officer would be —

In the case of an Executive Officer of the Company, less than two times his or her annualized base salary; and

In the case of a president, chief executive, or a vice president of one of the Company's majority-owned subsidiaries, less than one times his or her annualized base salary.

The policy does not apply to stock purchased in the open market prior to January 1, 2011.

Directors . Under the Board Governance Guidelines, within five years of initial election to the Board, each non-employee director is expected to own shares of the Company's common stock equal in value to five times the annual cash retainer payable to directors. Market value is determined by the acquisition price or the closing market price at the time of acquisition, as the case may be. See the section below entitled Director Compensation . All directors with five or more years of service on the Board have met this requirement.

In the event of an increase in the annual retainer, the Corporate Governance & Nominating Committee will review this guideline to determine if there is a need for a change to reflect the increase.

- 14 -

Claw-Back Policy . The Company's Claw-Back Policy applies to all bonuses, incentive compensation and the like that have been paid to an employee of the Company (whether in cash, in equity, or both) that were based on financial statements that are subsequently restated. If necessary, the compensation is adjusted so that the employee will have received no more and no less than the amount that he or she would have received had the financial statements been restated before the amount of the compensation was determined. The policy applies to all such compensation paid to an employee, whether or not the employee was culpable with respect to the error, event, act or omission that caused the restatement to be made.

Board Evaluations . Directors conduct an annual evaluation of the performance of the Board and its committees. Questionnaires are sent to each Board member and committee member. Replies are anonymous and are collected and summarized by the Chair of the Corporate Governance & Nominating Committee. The summary is then discussed by the independent directors in an executive session held for the purpose. Any areas of Board or committee performance that are identified as needing improvement or change are considered by the Corporate Governance & Nominating Committee, which then makes a recommendation to the Board on the matter.

In addition, the Chair of the Corporate Governance & Nominating Committee confers each year with each director individually to solicit comments about nominations for election and re-election to the Board, and to permit each director to express any concerns about the functioning of the Board, its committees and its members. Any comments a director may have about the Corporate Governance & Nominating Committee and its Chair are directed to the Chairman of the Board.

The Board's Risk Oversight . Directors identify and exercise oversight of the Company's material risks acting as the whole Board as well as through its three standing committees. At each of the Board's regularly-scheduled meetings, directors receive a briefing and an assessment of the Company's risks as they relate to:

Safety

Crisis management

Construction joint ventures

Information technology

Compensation

Risk Oversight by Board Committees. Each standing committee of the Board shares the risk oversight responsibility as shown in the table below:

Covenant compliance	Incentive compensation	Board membership
Accounting		Board governance
Internal controls

The Audit Committee . In furtherance of its risk oversight responsibility, the Audit Committee provides for the confidential, anonymous submission by employees and others of concerns regarding questionable accounting, auditing and any other matters. These submissions are collected by an independent organization specializing in those services, and are conveyed to the Chair of the Audit Committee, to the Company's Chief Compliance Officer, and to the Company's General Counsel.

The Compensation Committee . More information about the Compensation Committee and compensation risk can be found below in the section entitled Compensation Policies & Practices — Risk Management under the heading Executive Compensation .

The Corporate Governance & Nominating Committee . The Corporate Governance & Nominating Committee addresses some of its risk oversight responsibilities through identifying and recommending for nomination well-qualified independent directors; through the periodic review of the Board Governance Guidelines; and by conducting annual Board self-evaluations, and through the Chair of the Committee, individual director evaluations.

Selecting Director Nominees . The Board's Corporate Governance & Nominating Committee has the responsibility, among others, to identify and recommend for nomination by the Board (including by a majority of independent directors) qualified candidates for election as director.

The Corporate Governance & Nominating Committee has voted to recommend to the Board the nomination for re-election of Ms. Davenport and Messrs. Hemsley, Patton, Schaum, Scott and Varello, whose current terms expire at the 2017 Annual Meeting as well as Raymond F. Messer, who is not an incumbent director . If elected , all directors will serve for a one-year term .

Information about the background and qualifications of the nominees is set forth above in the section entitled Background & Skills of the Nominees under the heading Election of Directors (Proposal 1) .

The Corporate Governance & Nominating Committee has not specified any minimum qualifications for serving on the Board, but seeks to achieve a Board that is composed of individuals who have experience that is relevant to the needs of the Company, who have a high level of professional and personal ethics, and who contribute to the cognitive diversity of the Board, including business experience, public sector experience, professional training, public and private offices held, geographical representation, race, gender and age, among other considerations. Experience in the construction industry and in one or more of engineering, transportation, finance and accounting, corporate governance, senior management, and public sector matters are considered particularly valuable. An independent director candidate is expected to be committed to enhancing stockholder value, and to have sufficient time to carry out the duties of a director, both on the full Board and on one or more of its standing committees.

The Corporate Governance & Nominating Committee periodically assesses the strengths, experience and skills of the independent directors to determine if there is a gap in the skills or experience that the Board should seek to fill. Given the Company's size, the Committee realizes that it is difficult to achieve a Board with broad diversity. Whenever it is determined that replacement directors or additional directors are needed, the Corporate Governance & Nominating Committee will perform a similar assessment. The Committee has not established a policy or particular methodology regarding the consideration of director candidates recommended by stockholders.

- 16 -

In late 2016, the Committee conducted the gap analysis of the skills of current directors referred to above and concluded that the Board would benefit from additional experience in construction, engineering and/or construction operations.

The Committee then developed a specification for this type of candidate and sought and reviewed referrals from current board members, Company executives and advisors. Candidates' résumés were reviewed and the field was narrowed to several leading candidates. These candidates were first interviewed by telephone and then in person by members of the Committee as well as by other independent directors and senior management using interview questions and an evaluation form that the Committee had developed. The Committee reviewed the evaluations and unanimously agreed that Raymond F. Messer had the experience, qualifications, attributes and skills that Committee was seeking.

If a stockholder wishes to recommend a person as a candidate for nomination as a director, the stockholder should follow the procedure for communicating with the Board that is described above in the section entitled Communicating with the Board . Recommendations of candidates for nomination for the 2018 Annual Meeting must be received by the date set forth below under the heading Submission of Stockholder Proposals .

Compensation Discussion and Analysis . This discussion and analysis of executive compensation covers the compensation awarded to, earned by, or paid to the named executive officers. It covers the material elements of their compensation, including the following:

The objectives of the Company's compensation programs and what they are designed to reward;

The elements of the named executive officers' compensation, and why the Compensation Committee has chosen those elements;

How the amounts and compensation formulas were determined, and how they fit into the Company's overall compensation objectives; and

The results of the most recent stockholder advisory vote on executive compensation.

The objectives of the Company's compensation programs and what they are designed to reward . The Compensation Committee of the Board of Directors, which is currently composed of three directors, all of whom are independent, oversees and approves the compensation of the named executive officers. The Committee's compensation objectives are as follows:

To provide a rate of pay for the work the executive does that is appropriate in comparison to similar companies in the industry, and that is considered fair by the executive and the Committee;

To give the executive a significant incentive to perform at a high level, to reward that level of performance if achieved, and thereby to contribute to the Company's financial success;

To give the executive an incentive to remain with the Company; and

In the case of newly-hired executives, to provide them with an incentive to leave a prior employer and join the Company, and in some cases, to relocate.

The elements of the named executive officers' compensation, and why the Compensation Committee has chosen those elements.

Except as noted otherwise, executives are compensated through annual salaries and an incentive compensation plan. Annual salaries are designed to compensate the executive for the performance of his or her day-to-day responsibilities. The incentive compensation arrangements are designed to give the executives the opportunity to earn additional compensation, a portion of which — currently 50% — is paid in shares of the Company's common stock, if certain goals are met, that are subject to restrictions on their transfer and to forfeiture under certain circumstances.

Performance-Based Incentive Compensation . Incentive compensation consists of both cash and Company shares. While cash is an obvious incentive, the stock portion of incentive compensation is designed to encourage executives to take a longer-term perspective in fulfilling their responsibilities, and to align their financial interests with those of the Company's stockholders.

Incentive compensation is performance-based because it is dependent on the achievement of Company financial goals and the executive's individual performance goals. Financial goals, which for some executives also include operating-unit financial goals, tie a portion of incentive compensation to the team effort required for Company-wide success, while the individual performance goals are designed to concentrate the executives' attention on their own contributions to the overall effort.

Change-in-Control Agreements. The Company does not currently have a change-in-control severance agreement with any employee. However, it is the Committee's policy to provide that restrictions on outstanding restricted stock lapse in the event of a change in control because the Committee believes that the adverse effect on non-transferable stock held by employees when a change in control occurs, particularly in a public company, can be significant. The Compensation Committee believes that change-in-control agreements may become appropriate for executives whose employment is likely to be adversely affected by a change in control. Change-in-control agreements can be in the best interests of the Company and its stockholders because they provide the executive with a clear incentive to remain neutral as to any change-in-control transaction, should one arise, and undistracted by concerns as to his or her future employment. Generally, the Committee believes that change in control severance should only be payable if the executive's employment is terminated without cause shortly before, or within a year or two after, the change in control.

- 25 -

How the amounts and compensation formulas were determined, and how they fit into the Company's overall compensation objectives .

Generally, the amount of an executive's compensation is based in part on a determination of comparable compensation levels in the construction industry and the personal judgement of the members of the Compensation Committee, drawing on their own business experience. For newly-employed executives, their prior salaries are also taken into account. The Committee attempts to set executives' salaries neither substantially higher nor substantially lower than the median in the industry.

Current Executive Officers.

Mr. Varello . Mr. Varello's nominal salary is unusual, and was adopted at his request to conserve the Company's cash resources and because of his faith in the future of the Company. His restricted stock award was made in lieu of a cash salary and was submitted to, and approved by, stockholders at the 2015 Annual Meeting.

Mr. Wadsworth . Mr. Wadsworth's salary is based on his prior salary as President of the Company's Ralph L. Wadsworth Construction Company, LLC subsidiary, increased to reflect his taking on additional responsibilities when he was promoted to Chief Operating Officer in March 2016.

Mr. Ballschmiede . When he joined the Company, Mr. Ballschmiede's compensation was negotiated by him and the Compensation Committee using both comparable salaries in the industry for chief financial officers, and his extensive accounting and financial expertise and experience evidenced by his distinguished résumé.

Mr. Cutillo . Mr. Cutillo joined the Company as a vice president in October of 2015 at an initial salary of $275,000 that was subject to an increase to $300,000 upon completion of two short-term tasks related to his position as Vice President — Strategy & Business Development. He accomplished those tasks, and in May 2016, he was promoted to Executive Vice President & Chief Business Development Officer with expanded responsibilities and an increased annual salary of $325,000. In February 2017, Mr. Cutillo was elected President of the Company at an annual salary of $450,000. Mr. Cutillo's level of compensation was determined by the Compensation Committee with the assistance of an outside compensation consultant, Meridian Compensation Partners, LLC.

Mr. Barzun . Mr. Barzun's salary was established in 2006 at $60,000 based on the fact that he would be serving on a part-time basis as the Company's General Counsel; by 2013, it had risen to its current level ($100,000) through merit increases as a result of increasing responsibilities. The Compensation Committee treats his salary as an annual retainer for the performance of routine matters, which, after the end of the year, is subject to increase by an amount that the Committee believes reflects appropriate compensation for the non-routine matters on which he worked during the year.

Compensation Consultant — Independence . Meridian was first retained by the Compensation Committee in 2014 to provide advice on the design of a short- and long-term incentive compensation plan. In rendering services, Meridian, at that time and currently, reports directly to the Compensation Committee, and the Compensation Committee has the sole authority to retain or dismiss Meridian and to approve its fee arrangements. The Compensation Committee assessed the independence of Meridian pursuant to Securities and Exchange Commission rules, and concluded that its work for the Compensation Committee did not raise any conflict of interest.

- 26 -

Meridian has performed no services of any kind for the Compensation Committee, the Board, or the Company other than as described above. Meridian's fees for this work, $23,278, was billed in 2017.

Compensation Consultant — Benchmarking . In 2016, Meridian was asked to benchmark the compensation of the position of president in contemplation of Mr. Cutillo's possible promotion. In seeking a useful peer group, the Compensation Committee and Meridian recognized that there are few publicly-traded companies in the heavy civil construction business that are close to the Company's size. Most other publicly-traded heavy civil construction companies are much larger than the Company and are companies with which the Company rarely competes. Accordingly, the Compensation Committee decided to use the following peer group with which the Company competes for talent:

Willbros Group Inc.

Layne Christensen Company

Great Lakes Dredge & Dock Corporation

U.S. Concrete, Inc.

Orion Group Holdings, Inc.

Argan, Inc.

IES Holdings, Inc.

Based on Meridian's analysis, the Compensation Committee set Mr. Cutillo's salary slightly below median of the peer group to reflect the fact that he is a newly-elected President.

The results of the most recent stockholder advisory vote on executive compensation .

The Company conducts annual advisory votes on executive compensation. At the 2016 Annual Meeting, the vote was as follows:

Number of Shares Entitled to Vote	Voted For	Voted Against	Abstained
14,586,623	13,640,928 (93.5%)	509,528 (3.3%)	436,167 (3.2%)

The Compensation Committee believes that this vote indicates general stockholder satisfaction with the Company's executive compensation policies and decisions. In the event that stockholders do not approve executive compensation for a given year, the Compensation Committee will review its decisions on compensation structure and levels, as well as the comparability of the executives' compensation to that of a peer group of companies before deciding whether to make any change in the compensation of one or more of the executives.

Incentive compensation arrangements for 2016 . In February 2016, the Compensation Committee adopted an incentive compensation plan for executives and others. The 2016 Executive Incentive Compensation Program was a one-year plan that provided for establishing for participants as of the beginning of 2016 a target amount, which is the amount that can be earned by the participant if all the goals of the program were achieved in 2016. The target amount is expressed as a percent of the participant's base salary.

Under the plan, incentive compensation was earned based on the level of achievement of a Company earnings-per-share (EPS) goal for 2016 that accounted for 50% of incentive compensation and individual performance goals that accounted for the other half. In 2016, the EPS goal was not achieved. For participants in the Company's operating units, there was also an operating-unit goal based on the unit's earnings before interest and taxes (EBIT). In 2016, certain EBIT goals were achieved. The financial and individual performance goals of officers of the Company and of the chief executives of the Company's subsidiaries were subject to approval by the Compensation Committee.

- 27 -

Pursuant to the plan, payment of one-half of incentive compensation earned under the plan was made in cash, and one-half was made in the form of an award of shares of the Company's common stock that are subject to restrictions on their sale or other transfer and to forfeiture in certain circumstances, in order to align participants' interests with those of the Company's stockholders and serve to encourage participants to remain in the Company's employ. One executive officer, for personal reasons, was paid all in cash. The restrictions on the restricted stock lapse at the end of three years if the participant is then still an employee of the Company or operating unit, as the case may be.

If during 2016 a participant had resigned or his or her employment were terminated for cause, all benefits under the program would have been forfeited. If during 2016 a participant's employment were terminated without cause, for permanent disability, or because of the death of the participant, a pro-rated portion of earned program benefits would have been paid based on the financial results for the year, an assumption that the participant completed all individual performance goals satisfactorily, and the number of days during the year the participant was an employee.

The fact that the plan had no long-term goal reflects the Compensation Committee's view that in light of the volatility of the Company's common stock, a long-term goal, such as the total shareholder return goal that was a feature of the long-term element of the 2015 incentive compensation plan, would be unlikely to serve as an incentive to executives, who were fully concentrated on the short-term in furtherance of the Company's return to profitability.

Incentive compensation arrangements for 2017 . In February 2017, the Compensation Committee adopted an executive incentive plan for 2017 that is essentially the same as the 2016 incentive plan except in certain respects. In the 2017 plan, the financial goal accounts for 75% of incentive compensation and individual performance goals account for 25%, reflecting the Compensation Committee's desire to put more emphasis on Company-wide financial performance. The restricted stock awards will vest annually in three installments, which the Compensation Committee believes has the same effect of aligning executives' financial interests with stockholders' interests, but serves as a more immediate incentive than the three year, so-call 'cliff vesting' of the 2016 plan.

For the same reasons described above for the 2016 plan, no long-term element was included in the 2017 plan. The Compensation Committee will consider adding a long-term goal to future incentive compensation plans when it believes that long-term goals can be reasonably established.

The following table shows some additional information about the participation of the named executive officers in the 2017 plan. As noted above, neither Messrs. Varello nor Barzun are participants in the plan.

Program term:	One year (January 1 – December 31, 2017)
Target amount as a percent of base salary:	Joseph A. Cutillo 195% Con L. Wadsworth 170% Ronald A. Ballschmiede 170%
Weighting of the EPS goal: Minimum required goal achievement level: Cap on goal achievement level:	75% of the Target Amount 80% 120%
Weighting of individual performance goals:	25% of the Target Amount with no minimum and no cap.

Additional information on executive compensation .

All incentive compensation, whether paid in cash or stock, is subject to recovery by the Company, irrespective of culpability, if the Company restates the financial statements on which the incentive compensation was based.

For more information on payments to the executives in the event of the termination of their employment, see the section below entitled Potential Payments upon Termination or Change-in-Control .

A description of the material terms of the employment agreements and arrangements of the named executive officers is set forth below in the section entitled Employment Agreements of the Named Executive Officers .

Additional information about the 2016 Incentive Compensation Plan is set forth below in the section entitled Grants of Plan-Based Awards in 2016 .

Compensation Policies & Practices — Risk Management .

The Compensation Committee has reviewed the Company's compensation policies and practices, and in particular its incentive compensation and bonus policies, as they relate to risk management, and has determined that they support the Committee's compensation objectives without encouraging inappropriate, unintended, or excessive risk-taking by employees, and are not reasonably likely to have a material adverse effect on the Company. The Compensation Committee elected not to hire an outside adviser in undertaking its risk review in 2016. For a full description of the Company's significant risk factors, see Item 1A. Risk Factors in the Company's 2016 Annual Report on Form 10-K, which is available with this Proxy Statement.

In reaching its conclusions, the Compensation Committee took into account many factors, including the fact that because of the nature of the Company's business, any short-term manipulation of financial results will have an adverse effect over time, as follows:

Incentive compensation is paid in part in equity that vests over time, thereby subjecting the recipient's stock to extended market risk.

Officers of the Company and its subsidiaries are subject to stock retention requirements, which also subject their stockholdings to market risk.

There are appropriate caps on the amount of incentive compensation that can be earned.

Most of the Company's projects are performed over the course of more than one calendar year, so that a manipulated increase in profits in one year will have the effect of reducing profits in the subsequent year and vice versa.

The Company's claw-back policy applies to both cash and equity incentive compensation irrespective of whether or not the recipient of the compensation was at fault.

Percentage-of-Completion Accounting . The Compensation Committee considers that, by their nature, the percentage-of-completion accounting and revenue recognition rules under which the Company is required to prepare its financial statements may be susceptible to manipulation. Percentage-of-completion accounting requires management to make estimates at least every month of the cost of completing projects that are on-going at the date of the review. These estimates directly affect reported profits, and profits, directly or indirectly, are the basis for the award of half or more of the Company's incentive compensation. The Compensation Committee believes that this risk is mitigated in the following ways:

Senior executives perform rigorous project reviews on a monthly basis to review estimates for any potential inaccuracies.

- 29 -

The Company's independent auditors review the current year's estimates and compare them to actual, prior-year results, so that over time, any manipulation of results should become evident.

As noted above, because most of the Company's large projects are performed over the course of more than one fiscal year, a manipulated increase in profits in one year will have the effect of reducing profits in the subsequent year, and vice versa.

The Total Stockholder Return Goal . Under the 2015 incentive compensation program, the long-term goal for the vesting of restricted stock units is based on the change in the Company's stock price over a period of three years (total shareholder return, or TSR) compared with the TSR of a peer group of companies over the same period. The Committee believes that manipulation of the Company's stock price to achieve this goal would be particularly difficult because the Company's small float makes the stock price susceptible to swings and variations unaffected by the Company's financial performance, and because of the unpredictability of the types of events and circumstances that actually affect the Company's stock price.

Employment Agreements of the Named Executive Officers . For the effects of the termination of employment of the named executive officers, see the section below entitled Potential Payments upon Termination or Change-in-Control .

The following table shows the material financial features of the employment agreements or arrangements of the named executive officers for 2017. Messrs. Varello and Barzun do not participate in an incentive plan. Messrs. Cutillo, Wadsworth and Ballschmiede do not have employment agreements.

Name	Annual Salary	Target Incentive Compensation as a Percent of Salary	Percent Allocated to EPS Goal	Percent Allocated to Individual Performance Goals	Percent Paid in Cash	Percent Paid in Restricted Stock
Paul J. Varello	$1.00	N/A	N/A	N/A	N/A	N/A
Joseph A. Cutillo	$450,000	195%	75%	25%	50%	50%

Roger M. Barzun ⁽¹⁾	$100,000	N/A	N/A	N/A	N/A	N/A

(1)

Mr. Barzun's salary is subject to increase by an amount that the Compensation Committee believes reflects appropriate compensation for the non-routine matters on which he worked during the year.

Mr. Varello . Mr. Varello entered into an employment agreement with the Company in March 2015 when he resigned as Chairman of the Board and ceased to be Chief Executive Officer of the Company on only an interim basis. The agreement expires on the third anniversary of its March 9, 2015 effective date. It provides for a salary of $1.00 per year and a single restricted stock award of 600,000 shares that vests in equal installments over three years. The award was approved by stockholders at the 2015 Annual Meeting. In place of participating in the Company's health plan, the agreement provides for the reimbursement of his out-of-pocket costs of maintaining the family health insurance coverage that he was maintaining prior to becoming Chief Executive Officer, and any replacement coverage that he may elect to obtain from time to time. He is also entitled to the use of a Company-owned vehicle.

Mr. Cutillo . Mr. Cutillo does not have an employment agreement. The basis for his salary as President is discussed above under the heading Compensation Discussion and Analysis — Current Executive Officers . In addition to his salary and participation in the 2017 executive incentive compensation plan, he is entitled to the use of a Company vehicle, the expenses of which are paid by the Company.

- 30 -

Mr. Wadsworth . Mr. Wadsworth does not have an employment agreement. The basis for his salary is discussed above under the heading Compensation Discussion and Analysis — Current Executive Officers .

Mr. Ballschmiede . Mr. Ballschmiede does not have an employment agreement. He was hired on an at-will basis at an annual salary that is subject to annual reviews by the Chief Executive Officer, with any increase being subject to the approval of the Compensation Committee. In addition, upon becoming an employee, he was awarded 100,000 shares of restricted stock that vest in two equal annual installments.

Mr. Barzun . Mr. Barzun's employment agreement became effective in March 2006 and continues until terminated by the Company or by Mr. Barzun. His salary is subject to annual merit increases. The Compensation Committee treats his salary as an annual retainer for the performance of routine matters, which, after the end of the year is subject to increase by an amount that the Committee believes reflects appropriate compensation for the non-routine matters on which he worked during the year.

Potential Payments upon Termination or Change-in-Control . The table below describes the events that would trigger payments or the provision of other benefits to the named executive officers in the event of the termination of their employment or a change in control of the Company. The Company would provide all the payments and benefits described below. The amounts assume that the termination or change in control occurred on December 31, 2016.

Mr. Varello's employment agreement prohibits him from competing with the Company or soliciting its employees while employed by the Company and for eighteen months after his employment terminates. Messrs. Wadsworth, Ballschmiede and Barzun are not subject to those prohibitions. Mr. Varello's employment agreement also prohibits him indefinitely from disclosing the Company's confidential information.

Triggering Event	Executive	Payments & Benefits
Termination of the executive's employment by the Company without cause. ⁽¹⁾	Mr. Varello Mr. Wadsworth Mr. Ballschmiede	All of the shares under the executives' outstanding restricted stock awards, if any, vest in full* but no severance is payable other than that traditionally paid to other salaried employees.
	Mr. Cutillo
	Mr. Barzun	One year's salary.
Termination by the Company for cause. ⁽²⁾ and Voluntary resignation by the executive.	All executives	No severance compensation is paid, and all of the shares under their outstanding restricted stock awards, if any, are forfeited.
A change in control of the Company.	All executives	All of the shares under the executives' outstanding restricted stock awards, if any, vest in full. ^*
		At December 31, 2016 the closing price of the Company's common stock was $8.46 per share. Accordingly, the total market value of the shares subject to restrictions that would have vested in a change in control of the Company on December 31, 2016 are as follows:
			Mr. Varello	$3,384,000
			Mr. Ballschmiede	$423,000
			Mr. Cutillo	$211,500
		Messrs. Wadsworth and Barzun held no restricted stock at December 31, 2016.

- 31 -

The accelerated release of restrictions (vesting) triggers no additional Company payment obligation, but it does accelerate the recognition by the Company of the cost of the award.

(1)

A termination without cause is a termination for any reason other than a termination for cause or a voluntary resignation, and in the case of Mr. Varello, includes a resignation that is the result of a breach by the Company of a material provision of his employment agreement.

(2)

The term "cause" is a defined term for an executive with an employment agreement and/or a restricted stock award agreement, and means what is commonly referred to as cause in employment matters, such as gross negligence, dishonesty, insubordination, inadequate performance of responsibilities, and the like.

PERFORMANCE GRAPH

The following graph compares the percentage change in the Company's cumulative total stockholder return on its common stock for the last five years with the Dow Jones US Index, a broad market index, and the Dow Jones US Heavy Construction Index, a group of companies whose marketing strategy is focused on a limited product line, such as civil construction. Both indices are published in The Wall Street Journal. The returns are calculated assuming that an investment with a value of $100 was made in the Company's common stock and in each index at the end of 2010, and that all dividends were reinvested in additional shares of common stock, although the Company has paid no dividends during the periods shown. The graph lines merely connect the measuring dates, and do not reflect fluctuations between those dates. The stock performance shown on the graph is not intended to be indicative of future stock performance.

Con L. Wadsworth . Mr. Wadsworth was a Senior Vice President of the Company from June 2014 through February 13, 2015 when he voluntarily gave up that position, but remained the President of the Company's Ralph L. Wadsworth Construction Company, LLC subsidiary (RLW). Effective March 10, 2016, Mr. Wadsworth was elected the Company's Executive Vice President & Chief Operating Officer, and was replaced as President of RLW by Brandon Squire, its Executive Vice President & Chief Operating Officer.

- 36 -

Mr. Wadsworth and some of his immediate family members are part owners of the following companies with which RLW had a business relationship in 2016. Their ownership interests are shown in the table below.

Wadsworth & Sons II (W&S2). RLW is the general contractor on five projects totaling $4.1 million, the largest being a $3.7 million project designated as Exchange Building "B" in Draper, Utah, which is owned by W&S2. The projects were completed by the end of 2016.

W&S2 & Wadsworth Corporate Center Building A, LLC (WCC) . RLW leases its primary office space from W&S2 through WCC, an entity owned and managed by W&S2, at an annual rent of $330,989, and common area maintenance charges of $118,853. This lease expires in 2022.

Wadsworth Dannon Way, LLC (WDW) which is part of Wadsworth & Sons LLC and Wadsworth & Sons III (W&S3) . In 2016, RLW leased —

a facility for RLW's equipment maintenance shop from WDW at an annual rent of $200,791 plus common area maintenance charges of $76,320; and

a facility to provide temporary living quarters for field employees from W&S3 on a month-to-month basis for total 2016 rent of $34,000.

The W&S3 lease expired in 2014 and was renewed on a month to month basis starting in November 2014 at the same rent.

Big Sky, LLC . Big Sky, LLC is an entity owned and managed by W&S3. Big Sky owns a plane that RLW has rented since 2014 for certain business travel of its employees, including Mr. Wadsworth, for which RLW paid Big Sky rental fees and expenses totaling $35,612 in 2016.

Policies & Procedures for the Review, Approval or Ratification of Transactions with Related Persons .

General . The Board's policy on transactions between the Company and related persons is set forth in the written charter of the Audit Committee. The policy requires the Audit Committee to review in advance the terms of any transaction between the Company (including its subsidiaries) and a director, executive officer, nominee for election as a director, or stockholder; and any of their affiliates or immediate family members that involves more than $100,000.

Any new transaction is taken under consideration by the Audit Committee, and both new and existing transactions, such as the W&S3 plane rental fees, are reviewed periodically to ensure, among other considerations, that they are in compliance with Delaware law and are on terms that are no less favorable to the Company (including its subsidiaries) than could be obtained from unrelated third parties.

Mr. Wadsworth . As part of its due diligence review prior to the acquisition of an 80% interest in RLW, the Company reviewed the relationships and transactions between RLW, Mr. Wadsworth and Mr. Wadsworth's family members, and concluded that the prices being charged to RLW or by RLW, as the case may be, are competitive and no less favorable to RLW than could be obtained from unrelated third parties. These amounts are also reviewed periodically.

A representative of the Company's independent registered public accounting firm, Grant Thornton LLP, is expected to be available at the 2017 Annual Meeting and will have the opportunity to make a statement, if he or she wishes, and to respond to appropriate questions from stockholders.

The following table sets forth the aggregate fees that Grant Thornton billed to the Company for the years ended December 31, 2016 and 2015.

Tax Fees:	N/A	—	—	N/A
All Other Fees (non-audit fees):	N/A	—	—	N/A

Audit Fees . In 2016 and 2015, audit fees included the fees and expenses for Grant Thornton's audit of the consolidated financial statements included in the Company's Annual Report on Form 10-K for those years; the reviews of the consolidated financial statements included in the Company's quarterly reports on Form 10-Q; the resolution of issues that arose during the audit process; attestation work required by Section 404 of the Sarbanes-Oxley Act of 2002; and other audit services that are normally provided in connection with statutory and regulatory filings. In 2016, a portion of the audit fees related to the Company's May 2016 public offering of common stock.

Of the audit fees for 2016 reflected in the above table, $795,368 had been billed by December 31, 2016. Of the audit fees for 2015 reflected in the above table, $778,771 had been billed by December 31, 2015.

Audit-Related Fees . In 2016, the Company incurred $158,978 for a due diligence project on a target company. In 2015, the Company incurred no fees in this category.

Tax Fees . The Company's independent registered public accounting firm occasionally provides tax consulting services to the Company. No fees for such services were incurred in 2016 or 2015.

All Other Fees (Non-Audit Fees) . In 2016 and 2015, there were no fees paid to Grant Thornton that are related to any other services provided to the Company.

Procedures for Approval of Services . All requests for services that are to be provided by the Company's independent registered public accounting firm, which must include a detailed description of the services to be rendered and the amount of corresponding estimated fees, are submitted to both the Company's Chief Financial Officer and the Chair of the Audit Committee. The Chief Financial Officer authorizes services that have been approved by the Audit Committee within pre-set limits. If there is any question as to whether a proposed service fits within an approved service, the Chair of the Audit Committee is consulted for a determination. The Chief Financial Officer submits to the Audit Committee any requests for services that have not already been approved by the Audit Committee. The request must include an affirmation by the Chief Financial Officer and the independent registered public accounting firm that the request is consistent with the SEC’s rules on auditor independence.
