Title
Resolution to Approve a Construction Contract with Granite Inliner, LLC for the Nichols Arboretum Sanitary Sewer Lining Project ($1,734,293.00) (ITB 4686)
Memorandum
Attached for your review and approval, please find a resolution that awards a construction contract to Granite Inliner, LLC for the Nichols Arboretum Sanitary Sewer Lining Project.
Project Description
This project consists of lining approximately 6,520 feet of 8-inch and 10-inch sanitary sewers which serve the areas adjacent to Nichols Arboretum. Due to their location, these sanitary sewers are difficult to access and maintain, and thus have a history of maintenance issues including sanitary sewer overflows that have previously been reported to the Michigan Department of the Environment, Great Lakes, and Energy (EGLE). Lining these pipes will greatly reduce the likelihood of such overflows occurring.
Lining is a trenchless technology which enables the pipe to be repaired without disturbing the surface above. The lining of this sanitary sewer is critical to extending the service life of these pipes. The project is expected to begin in October 2021. Timing and details of this project have been coordinated with the University of Michigan and Arboretum staff.
Plans and specifications were advertised through BidNet (ITB No. 4686). One bid was received and opened on August 10, 2021. This bid was submitted by Granite Inliner, LLC in the amount of $ 1,734,293.00 which was higher than the engineer's estimate of $1,114,485.00. Staff has reviewed the bid, and believes the prices reflect the current bidding environment as well as the difficult nature of the work.
Granite Inliner, LLC submitted all required Responsible Contractor Criteria, Non-Discrimination, Prevailing Wage, Living Wage, and Conflict of Interest Disclosure forms; and complies with the requirements of the Non-Discrimination, Prevailing Wages, and Living Wage ordinances.
