Subject: Closeout for WW-685R North Shore Pump Station Wet Weather Improvements (PeopleSoft Contract ID: 1000021055)
The Contract Monitoring Division (“CMD”) has determined that Western Water Constructors, Inc. (“Western Water”), the prime contractor, has made a good faith effort to comply with the LBE subcontracting requirements associated with this project.
At the time the project was advertised, an LBE subcontracting participation requirement of 11% was established. Western Water’s Section 00 43 36 reflected an LBE subcontracting participation of 11.67%.
Western Water was awarded the contract in the amount of $28,610,000.00. At closeout, the final contract amount is $27,844,062.81. Western Water’s Micro/Small LBE subcontracting participation is as follows:

Based on the foregoing, CMD concurs with the closeout of this contract. Should you have any questions, please contact me at [email protected].
