Report
Summary
The purpose of this project is to replace the grit basins and supporting facilities at the 23rd Avenue Wastewater Treatment Plant (WWTP). Grit removal systems take grit material (sand, stones, rocks, construction material, etc.) out of the wastewater treatment process to increase process capacity and reduce maintenance costs. The original WWTP grit basins were constructed in 1984. A recent assessment revealed the grit removal systems have reached the end of their useful operational life and rehabilitation is no longer cost effective. This project will include replacement of the grit removal basins, pumps, and other facilities.
McCarthy will begin in an agency support role for CMAR Preconstruction Services. McCarthy will assume the risk of delivering the project through a Guaranteed Maximum Price agreement.
McCarthy’s services include, but are not limited to: providing detailed cost estimating and identification of marketplace conditions; planning and scheduling project/construction phases to minimize interruption to City operations; evaluating alternate systems; providing constructability studies; advising on potential efficiencies in project delivery; performing and initiating long-lead studies and procurements; and assisting in permitting processes. A Small Business Enterprise goal will be established for this project upon substantial completion of Preconstruction Services and prior to the start of construction.
