It also included flocculator recoating and component repairs, basin floor slab repairs, basin wall cracks and expansion joint repairs. AECOM USA, Inc. dba AECOM USA Group, Inc. designed the project with 900 calendar days allowed for construction.

The project was completed beyond the established completion date with an additional 2497 days approved by Change Order Nos. 1-5, 7-9. The final cost of the project, including overrun and underrun of estimated unit price quantities and previously approved Change Order Nos. 1-7, and 9 is $7,874,596.28, an increase of $142,383.19 or 1.84% over the revised Contract Amount. The increased cost is a result of the difference between planned and measured quantities.
M/WSBE PARTICIPATION: The advertised M/WBE contract goals for this project were 12% MBE and 6% SBE (18% total). The M/W/SBE goals approved for this project were 12.06% MBE, 6.33% SBE, (18.39% total). According to the Office of Business Opportunity, the actual participation achieved on this project was 6.79% MBE, 4.24% SBE (11.03% total). The standard for meeting MWSBE participation goals is the demonstration of Good Faith Efforts. The Contractor’s M/W/SBE performance on this project was rated Satisfactory for the following reasons: While the Prime failed to meet the awarded contract goals, the prime demonstrated Good Faith Efforts to meet the goal. Due to the age of the contract, the B2G System recorded goal credit to the Prime for a second tier subconsultant that was not certified, therefore the Prime never received notification of non-compliance throughout the life of the contract. However, under OBO’s current rules, a first tier subconsultant could not receive goal credit for an uncertified firm.
