Resolution to Award a Construction Contract to Lanzo Companies, Inc. ($2,338,237.00, Bid No. ITB-4643) for the 2020 Sewer Lining Project
Memorandum
Attached for your review and approval is a resolution to award a contract to Lanzo Companies, Inc., in the amount of $2,338,237.00, for the 2020 Sewer Lining Project.
This project includes lining approximately 31,000 feet of sanitary and storm sewer at multiple locations throughout the City, as well as contingencies to repair or maintain segments of pipe where lining is not feasible. In addition, the project will line 50 sanitary sewer manholes to aid in limiting stormwater infiltration into the sanitary sewer system. Those locations are combined into one contract for efficiency and cost savings. The project locations were identified by City staff as in critical need of repair.

The project is expected to begin in January 2021.
