Exhibit 10.7

FIRST AMENDMENT TO INTERCREDITOR AGREEMENT

THIS FIRST AMENDMENT TO INTERCREDITOR AGREEMENT (“this Amendment”) is made and
entered into as of the 3rd day of December, 2012, by and between Federal
Insurance Company, an Indiana corporation (“Federal”); American Home Assurance
Company, National Union Fire Insurance Company of Pittsburgh, Pa., and The
Insurance Company of the State of Pennsylvania (collectively “AIG”); Liberty
Mutual Insurance Company, a Massachusetts company, Liberty Mutual Fire Insurance
Company, and Safeco Insurance Company of America (collectively, “Liberty
Mutual”); and Bank of America, N.A., a national banking association, as Lender
Agent on behalf of the other Lender Parties. All capitalized terms will have the
meaning set forth in this paragraph, the recitals, and Section 1.

WHEREAS, Federal, AIG, Liberty Mutual, and Lender Agent are party to that
certain Intercreditor Agreement dated as of March 14, 2005, as modified by that
certain Joinder Certificate dated as of November 28, 2006, wherein AIG was added
as a Surety, and as further modified by that certain Joinder Certificate dated
March 31, 2009, wherein Liberty Mutual was added as a Surety (collectively “the
Intercreditor Agreement”);

WHEREAS, the Trench Companies are contemporaneously herewith being sold to a
third party;

WHEREAS, in connection with such sale of the Trench Companies, Indemnitors have
requested, and Surety has agreed, subject to certain conditions, to remove and
release the Trench Companies as Principals and Indemnitors under the Surety
Credit Documents; and

WHEREAS, the sale of the Trench Companies requires the amendment and
modification of the Intercreditor Agreement as hereinafter set forth.

NOW, THEREFORE, in consideration of the foregoing and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto agree as follows:

1. Definitions. Capitalized terms used in this Amendment and not otherwise
defined are used herein as defined in the Intercreditor Agreement.

The definition of “Bonds” in Section 1 of the Intercreditor Agreement is amended
to add the following at the end of such definition: “ ‘Bonds’ will also mean any
surety agreements, undertakings, or instruments of guaranty signed by Surety on
behalf of any of the Trench Companies prior to the Sixth Amendment Effective
Date, exclusive of the Trench Open Bonds.

The definitions of “Indemnitors” and “Principal” in Section 1 of the Indemnity
Agreement are each amended to add the following to each such definition, at the
end of each such definition:

Notwithstanding the foregoing or anything in this Agreement or any other Surety
Credit Document to the contrary, in no event will any of the Trench Companies

--------------------------------------------------------------------------------

be an Indemnitor or Principal for purposes of this Agreement or any other Surety
Credit Document. The exclusion of the Trench Companies as Indemnitors and
Principals for the purposes of this Agreement and each other Surety Credit
Document will not limit the indemnity obligations of any of the Trench Companies
as may be agreed to by any of such Trench Companies in any other agreement
entered into by any of such Trench Companies (other than any Surety Credit
Document).

The definition of “Surety Loss” in Section 1 of the Intercreditor Agreement is
amended to restate subparagraph (a) of said definition (exclusive of items (1) –
(5) thereunder) to read as follows:

all damages, costs, reasonable attorney fees, and liabilities (including all
reasonable expenses incurred in connection therewith) which Surety actually
incurs by reason of (i) executing or procuring the execution of any surety
agreements, undertakings, or instrument of guarantee, or renewal or continuation
thereof, signed by Surety on behalf of (y) any Principal or Island Mechanical,
Hawaii, and (z) if requested by any Indemnitor, any Affiliates and Subsidiaries
of Quanta Services, Inc., (ii) Bonds which may be already or hereafter be
executed on behalf of any Principal and/or any Foreign Subsidiary, or renewal or
continuation thereof, and/or (iii) Bonds that were already executed by Surety
prior to the Sixth Amendment Effective Date on behalf of any of the Trench
Companies, or renewal or continuation thereof, exclusive of the Trench Open
Bonds; or which Surety actually incurs by reason of making any investigation on
account thereof, prosecuting or defending any action in connection therewith,
obtaining a release, recovering, or attempting to recover any salvage in
connection therewith or enforcing by litigation or otherwise any of the
provisions of this Agreement, including, but not limited to:
