Title
Resolution to Approve a Construction Contract with Commercial Contracting Corporation for the WWTP Clear Well Improvements Project ($1,335,000.00, ITB 4680)
Memorandum
Your approval is requested for a construction contract with Commercial Contracting Corporation (CCC) in the amount of $1,335,000.00 to construct the Wastewater Treatment Plant (WWTP) Clear Well Improvements Project.
The City's WWTP utilizes 12 sand filters for tertiary treatment to remove fine solids from the water. Filtered water is collected in two clear wells (north and south) where the water is aerated before it flows from the wells by gravity to the ultraviolet disinfection system prior to discharge to the Huron River. The clear wells are located under the Tertiary Filter Building and each is only accessible through several 4-foot by 4-foot openings, which means the clear wells are confined spaces with limited access and egress.
Concrete block baffle walls and air diffusers located in the two clear wells need replacement due their deteriorating and failing condition. These structures and equipment are essential to assure the intended operation of the clear wells and provide dissolved oxygen to ensure the WWTP complies with its discharge permit limits.
In response to ITB No. 4680, one bid to construct the WWTP Clear Well Improvements Project was received and publicly opened on June 1, 2021. The bid submitted was as follows:

WWTP staff is requesting your approval of a contract with CCC in the amount of $1,335,000.00 and to approve a contingency in the amount of $133,000.00 to fund additional necessary services as approved by the City Administrator.
