Title
Authority to advertise Contract 22-107-21, Installation of a New Air Diffuser System in the North Aeration Basin and associated work at the Egan Water Reclamation Plant (EWRP). estimated cost $3,024,000.00, Account 201-50000-645650, Requisition 1578162
Body
Dear Sir:
Contract documents and specifications have been prepared for Contract 22-107-21 to install a new air diffuser system in the North Aeration Basin and associated work at the Egan Water Reclamation Plant (EWRP). This contract will end December 31, 2023.
A new full-floor coverage air diffuser system will be installed as a test to compare its operation, maintenance requirements, and energy efficiency to the Metropolitan Water Reclamation District of Greater Chicago’s (District) standard spiral-roll diffuser system. In addition, the new diffuser system will include a pressure monitoring system to indicate diffuser fouling and a cleaning system to return fouled diffusers to an “as new” condition. Use of the pressure monitoring and cleaning systems allow for the most efficient operation of the diffuser system. The District’s Strategic Plan includes targets for 28 and 80 percent reduction in greenhouse gas emissions by 2025 and 2050, respectively, and 100 percent energy neutrality Districtwide by 2035. These targets require the District to consider energy efficiency. With aeration being one of the largest uses of energy at the District, it is prudent to evaluate other diffuser systems. Once installed, staff will evaluate the effectiveness of the new diffuser system as compared to the spiral roll configuration installed in the south aeration basin and the information will be used to inform future decisions.
This contract will install a new air diffuser system in Tank 2 of the North Aeration Battery at the EWRP, which includes the removal of two baffle walls, the replacement of the in-tank aeration piping and ceramic diffusers, and equipment to track diffuser performance. Additional aspects of this contract include other necessary maintenance items that need to be addressed to ensure that secondary treatment process operates as designed.
The estimated cost for this contract is $3,024,000.00. The estimated 2022 and 2023 expenditures are $1,000,000.00 and $2,024,000.00, respectively.
The bid deposit for this contract is $151,200.00.
The Multi-Project Labor Agreement will be included in this contract.
The Affirmative Action Ordinance, Revised Appendix D will be included in this contract. The type of work to be performed under this contract is within the general construction services category for establishing Minority-owned Business Enterprises (MBE), Women-owned Business Enterprises (WBE), Small Business Enterprises (SBE), and Veteran-owned Business Enterprises (VBE) goals. The tailored MBE, WBE, SBE, and VBE utilization goals for this contract are 20 percent MBE, 10 percent WBE, 10 percent SBE, and 3 percent VBE.
The tentative schedule for this contract is as follows:
Advertise May 11, 2022
