Exhibit 10.2

SECOND AMENDMENT TO
SECOND AMENDED AND RESTATED CREDIT AGREEMENT

THIS SECOND AMENDMENT TO SECOND AMENDED AND RESTATED CREDIT AGREEMENT (this “Amendment”), dated as of June 25, 2010, is entered into by and among AECOM Technology Corporation, a Delaware corporation (the “Company”), the several financial institutions identified on the signature pages hereto (hereinafter collectively referred to as the “Lenders” and individually as a “Lender”), Bank of America, N.A., as administrative agent (in such capacity, the “Administrative Agent”) and swing line lender (in such capacity, the “Swing Line Lender”), and Union Bank of California, N.A., Wells Fargo Bank, N.A., BMO Capital Markets Financing, Inc., and BNP Paribas, in their respective capacities as a syndication agent (each, a “Syndication Agent” and collectively, the “Syndication Agents”), with reference to the following facts:

RECITALS

A.          The Company, the Lenders, the Administrative Agent, the Swing Line Lender and the Syndication Agents are parties to the Second Amended and Restated Credit Agreement, dated as of August 31, 2007, as amended by the First Amendment to Amended and Restated Credit Agreement, dated as of December 31, 2007 (collectively, the “Credit Agreement”), pursuant to which the Lenders provide a revolving credit facility to the Company of up to $600,000,000.

B.           The Company proposes to issue up to $175,000,000 aggregate principal amount of its 5.43% Senior Notes, Due 2020 and up to $125,267,915 aggregate principal amount of its 5.62% Senior Discount Notes, Series B Notes Due 2022 (collectively, the “2010 Private Notes”).

C.           The Company anticipates that purchasers of the 2010 Private Notes will require that the Subsidiary Guarantors guarantee the Indebtedness of the Company under such notes (collectively, the “Private Note Guaranties”) and that such notes benefit from a negative pledge.

D.          While the issuance of the Private Notes themselves is permitted under Section 8.02(q) of the Credit Agreement and Contingent Obligations of otherwise permissible Subsidiary Indebtedness is permitted under Section 8.02(l) of the Credit Agreement, the Private Note Guaranties are currently regulated by the limitations set forth in Section 8.02(o) of the Credit Agreement, which would be insufficient to accommodate the Private Note Guaranties and future growth for other operational needs.

E.           The Company has requested that the Majority Lenders provide the following accommodations under the Credit Agreement in connection with the proposed 2010 Private Notes and Private Note Guaranties:

(i)            consent to the execution and delivery of the Private Note Guaranties by such Subsidiaries of the Company as are necessary to facilitate the issuance of the

1

2010 Private Notes (collectively, the “Required Private Note Guarantors”) without counting the Contingent Obligations of the Required Private Note Guarantors under the Private Note Guaranties toward the dollar limitation on Indebtedness and Contingent Obligations incurred by the Company and its Subsidiaries outside the Credit Agreement which is set forth in Section 8.02(o) of the Credit Agreement; and

(ii)           amend Section 8.02(l) of the Credit Agreement to allow guaranties by Subsidiaries of Indebtedness issued by the Company that is permitted under Section 8.02 of the Credit Agreement.

F.           The Company also requests that the Majority Lenders agree to amend the definition of “Lien” set forth in Section 1.01 of the Credit Agreement to exclude negative pledges, so that negative pledges, and any agreement to grant Liens (as opposed to the actual grant of such Lien), are no longer restricted under the negative covenant relating to Liens set forth in Section 8.01 of the Credit Agreement.

G.           The Majority Lenders are willing to grant such accommodations and agree to such amendments as set forth below.

NOW, THEREFORE, the parties hereby agree as follows:

1.           Defined Terms.  Any and all initially-capitalized terms used in this Amendment (including, without limitation, in the recitals to this Amendment) without definition shall have the respective meanings assigned thereto in the Credit Agreement.

2.           Consent to Private Note Guaranties; Exclusion of Private Note Guaranties from Limitation on Contingent Obligations of Subsidiaries.  Subject to the terms and conditions of this Amendment, the Majority Lenders hereby consent to the execution and delivery of Private Note Guaranties by the Required Private Note Guarantors and agree that the Contingent Obligations of the Required Private Note Guarantors under the Private Note Guaranties shall not count toward the dollar limitation on Indebtedness and Contingent Obligations under Section 8.02(o) of the Credit Agreement.

3.           Amendment to Definition of “Liens.”  Section 1.01 of the Credit Agreement is hereby amended such that the definition of “Lien” shall read in full as follows:

“Lien” means any lien, mortgage, pledge, security interest, charge or encumbrance of any kind (including any conditional sale or other title retention agreement or any lease in the nature thereof).

4.           Amendments to Indebtedness Negative Covenant.  Section 8.02(l) of the Credit Agreement is hereby amended and restated in its entirety to read in full as follows:

(l)            Contingent Obligations incurred by the Company or any Subsidiary with respect to Indebtedness of the Company or any other Subsidiary which is permitted to be incurred by the Company or such Subsidiary under this Section 8.02;

2

5.           Conditions Precedent.  The effectiveness of this Amendment shall be subject to the satisfaction of each of the following conditions:

(i)            This Amendment.  The Administrative Agent shall have received this Amendment, duly executed by the Company and the Majority Lenders;

(ii)           Acknowledgement of Guarantors.  Each of the Guarantors shall have executed the Acknowledgement of Guarantors attached to the end of this Amendment; and

(iii)          Amendment to Foreign Subsidiary Credit Agreement.  The Administrative Agent shall have received a conforming amendment to the Foreign Subsidiary Credit Agreement, duly executed by the Borrowers and the Majority Lenders under (and as defined in) the Foreign Subsidiary Credit Agreement.

6.           Reaffirmation and Ratification.  The Company hereby reaffirms, ratifies and confirms its Obligations under the Credit Agreement and acknowledges that all of the terms and conditions of the Credit Agreement, as amended hereby, remain in full force and effect.

7.           Events of Default.  After giving effect to this Amendment, the Company is not aware of the occurrence of any Default or Event of Default under the Credit Agreement.

8.           Integration.  This Amendment constitutes the entire agreement of the parties in connection with the subject matter hereof and cannot be changed or terminated orally.  All prior agreements, understandings, representations, warranties and negotiations regarding the subject matter hereof, if any, are merged into this Amendment.

9.           Counterparts.  This Amendment may be executed in multiple counterparts, each of which when so executed and delivered shall be deemed an original, and all of which, taken together, shall constitute but one and the same agreement.

10.         Governing Law.  This Amendment shall be governed by, and construed and enforced in accordance with, the internal laws (as opposed to the conflicts of law principles) of the State of New York.
