Not Applicable.

As a corporation incorporated in the State of Florida, we are subject to the Florida Business Corporation Act, or the Florida Act. Section 607.0831 of the Florida Act provides that a director is not personally liable for monetary damages to the corporation or any other person for any statement, vote, decision to take or not to take action, or failure to take any action as a director unless (1) the director breached or failed to perform his or her duties as a director and (2) the director’s breach of, or failure to perform, those duties constitutes (a) a violation of the criminal law, unless the director had reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful, (b) a circumstance under which the transaction at issue is one from which the director derived an improper personal benefit, either directly or indirectly, (c) a circumstance under which the liability provisions of Section 607.0834 are applicable, (d) in a proceeding by or in the right of the corporation to procure a judgment in its favor or by or in the right of a shareholder, conscious disregard for the best interest of the corporation, or willful or intentional misconduct, or (e) in a proceeding by or in the right of someone other than the corporation or a shareholder, recklessness or an act or omission which was committed in bad faith or with malicious purpose or in a manner exhibiting wanton and willful disregard of human rights, safety, or property. A judgment or other final adjudication against a director in any criminal proceeding for a violation of the criminal law estops that director from contesting the fact that his or her breach, or failure to perform, constitutes a violation of the criminal law; but does not estop the director from establishing that he or she had reasonable cause to believe that his or her conduct was lawful or had no reasonable cause to believe that his or her conduct was unlawful.

Indemnification by a Florida corporation of its directors and officers is generally governed by Sections 607.0850 through 607.0859 of the Florida Act, for which purposes, “director” or “officer” means an individual who is or was a director or officer of the corporation or is or was serving at the corporation’s request as a director or officer, manager, partner, trustee, employee or agent of another domestic or foreign corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or another enterprise or entity.

Under Section 607.0851, a corporation may indemnify an individual who is, was or threatened to be made a party to a proceeding because the individual is or was a director or officer against liability incurred in the proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any proceeding by judgment, order, settlement or conviction or upon a plea of nolo contendere or its equivalent shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in, or not opposed to, the best interests of the corporation or, with respect to any criminal action or proceeding, has reasonable cause to believe that his or her conduct was unlawful.

Under Section 607.0851, a corporation may not indemnify a director or officer in connection with a proceeding by or in the right of the corporation except for expenses and amounts paid in settlement not exceeding, in the judgment of the board of directors, the estimated expense of litigating the proceeding to conclusion, actually and reasonably incurred in connection with the defense or settlement of such proceeding, including any appeal thereof. Such indemnification shall be authorized if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation. In addition, upon application, a court of competent jurisdiction may order the corporation to indemnify or advance expenses notwithstanding that the director or officer did not meet certain standards of conduct or furnish certain undertakings if such court determines, among other things, that indemnification is fair and reasonable, but if the director or officer is adjudged liable, then such indemnification is limited to expenses incurred in connection with the proceeding.

Further, under Section 607.0852, the corporation must indemnify an individual who is or was a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which the individual was a party because he or she is or was a director or officer of the corporation against expenses incurred by the individual in connection with the proceeding.

Under Section 607.0858(1), the indemnification provided pursuant to Sections 607.0851 and 607.0852 and the advancement of expenses provided pursuant to Section 607.0853 are not exclusive, and a corporation may, by a provision in its articles of incorporation, bylaws or any agreement, or by vote of shareholders or disinterested directors, or otherwise, obligate itself in advance of the act or omission giving rise to a proceeding to provide any other or further indemnification or advancement of expenses to any of its directors or officers. However, indemnification under Section 607.0851 or Section 607.0858 or advancement of expenses under Section 607.0853 or Section 607.0858 shall not be made to or on behalf of any director or officer if a judgment or other final adjudication establishes that his or her actions, or omissions to act, were material to the cause of action so adjudicated and constitute: (a) a violation of the criminal law, unless the director or officer had reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful; (b) a transaction from which the director or officer derived an improper personal benefit; (c) in the case of a director, a circumstance under which the above liability provisions of Section 607.0834 are applicable; or (d) willful or intentional misconduct or a conscious disregard for the best interests of the corporation in a proceeding by or in the right of the corporation to procure a judgment in its favor or in a proceeding by or in the right of a shareholder.

Section 607.0857 provides that a corporation shall have the power to purchase and maintain insurance on behalf of directors and/or officers against liability asserted against or incurred by the individual in that capacity or arising from his or her status as a director or officer, whether or not the corporation would have power to indemnify or advance expenses to the individual against the same liability under Chapter 607.

Notwithstanding anything to the contrary in the foregoing, Section 607.0858(6) provides that a corporation’s power to indemnify, advance expenses to or provide or maintain insurance on behalf of or for the benefit of an individual who is or was an employee or agent is not limited by Sections 607.0850 through 607.0859.

Our Amended and Restated Articles of Incorporation provide that we shall indemnify any director or former director to the fullest extent permitted by law. Our Amended and Restated Bylaws provide that a director or officer may be paid expenses incurred in defending any proceeding in advance of its final disposition upon our receipt of an undertaking, by or on behalf of the director or officer, to repay all amounts so advanced if it is ultimately determined that such director or officer is not entitled to indemnification. Our Amended and Restated Bylaws also permit us to purchase and maintain insurance on behalf of our directors, officers, employees and agents and directors, officers, employees or agents of another corporation, partnership, joint venture, trust or other enterprise, serving as such at our request, against liabilities that they may incur in those capacities, whether or not we would have the power to indemnify them against such liabilities.

We have obtained primary and excess insurance policies insuring our directors and officers and our subsidiaries against certain liabilities they may incur in their capacity as directors and officers. Under such policies, the insurer, on our behalf, may also pay amounts for which we have granted indemnification to the directors or officers. In addition, we have individual indemnification agreements with our directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, it is the position of the Commission that indemnification of directors and officers for liabilities arising under the Securities Act is against public policy and is unenforceable pursuant to Section 14 of the Securities Act.

Not Applicable.

Item 9. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in this registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Exhibit 5.1

MasTec, Inc.

800 S. Douglas Road

12^th Floor

Coral Gables, Florida 33134

Ladies and Gentlemen,

On or about the date hereof, MasTec, Inc., a Florida corporation (the “Company”), transmitted for filing with the Securities and Exchange Commission (the “Commission”) a Registration Statement on Form S-8 (the “Registration Statement”) under the Securities Act of 1933, as amended (the “Act”). The Registration Statement relates to the registration by the Company of 1,150,000 shares (the “Shares”) of the Company’s common stock, $0.10 per share (“Common Stock”), that may be issued under the MasTec, Inc. Amended and Restated 2013 Incentive Compensation Plan (the “Restated 2013 ICP”). We have acted as counsel to the Company in connection with the preparation and filing of the Registration Statement.

In connection therewith, we have examined and relied upon the original or a copy, certified or otherwise identified to our satisfaction, of: (i) the Company’s Amended and Restated Articles of Incorporation, as amended and restated to date (the “Articles”) and Bylaws, as amended to the date hereof; (ii) records of corporate proceedings (the “Corporate Proceedings”) of the Company related to the Restated 2013 ICP; (iii) the Registration Statement and exhibits thereto; and (iv) such other documents, instruments and records as we have deemed necessary for the expression of the opinions contained herein. In making the foregoing examinations, we have relied, without investigation, on each of the following assumptions: (a) the legal capacity of each natural person to take all actions required of each such person in connection with the Registration Statement and the registration, issuance and sale of the Shares, (b) the genuineness of all signatures, the completeness of all documents submitted to us, the authenticity of all documents reviewed by us as originals, the conformity to original documents of all documents reviewed by us as duplicates or certified or conformed photocopies, (c) as to matters of fact, the truthfulness, accuracy and completeness of the information, representations and warranties of the Company made in the Registration Statement and in the records, documents, instruments, certificates and statements we have reviewed, (d) the due execution and delivery of all documents (except that no such assumption is made as to the Company) where due execution and delivery are a prerequisite to the effectiveness thereof, (e) that there has been no undisclosed waiver of any right, remedy or provision contained in such documents and (f) that the total number of shares of common stock issued and outstanding after the issuance of any of the Shares will not exceed the number of shares of common stock that the Company then has the authority to issue under the Articles. As to various questions of fact material to this opinion, we have relied, to the extent we deemed reasonably appropriate, upon statements and representations of officers or directors of the Company and upon documents, records and instruments furnished to us by the Company, without independently checking or verifying the accuracy of such documents, records and instruments.

Based upon the foregoing examination, and subject to the assumptions, qualifications and limitations stated herein, and assuming that (i) the Company reserves for issuance under the Restated 2013 ICP an adequate number of authorized and unissued shares of Common Stock and (ii) the consideration, if any, required to be paid in connection with the issuance and sale of Shares of Common Stock under the Restated 2013 ICP is actually received by the Company as provided in the Restated 2013 ICP, we are of the opinion that the Shares of Common Stock issued under the Restated 2013 ICP will be duly authorized, validly issued, fully paid and nonassessable.

This opinion is rendered solely in connection with the filing of the Registration Statement, is limited to the matters stated herein, and no opinions may be implied or inferred beyond the matters expressly stated herein. This opinion may not be relied upon for any other purpose without our prior written consent in each instance. Further, no portion of this letter may be quoted, circulated or referred to in any other document for any other purpose without our prior written consent.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. In giving such consent, we do not admit that we come within the category of persons whose consent is required by Section 7 of the Act or the rules and regulations of the Commission promulgated thereunder.

The opinions expressed herein are specifically limited to the corporate laws of the State of Florida and the federal securities laws of the United States of America and are as of the date hereof and we express no opinion as to matters governed by laws of any jurisdiction other than the corporate laws of the State of Florida and the federal securities laws of the United States of America, as in effect on the date hereof. This opinion speaks only as of the date hereof and we assume no obligation to update or supplement such opinions to reflect any facts or circumstances that may hereafter come to our attention, whether existing before or arising after the date hereof, or any changes in law that may hereafter occur.
