Title
Resolution to Approve a Contract with DUCTZ of North America LLC d/b/a DUCTZ of SE Michigan for the Guy C. Larcom City Hall Duct Cleaning Project (ITB 4671 - $69,550.00)
Memorandum
We recommend your approval of the attached resolution authorizing a contract in the amount of $69,550.00 with DUCTZ of North America LLC d/b/a DUCTZ of SE Michigan for the cleaning of HVAC ducts, air handlers and other system appurtenances at the Guy C. Larcom City Hall building.
Periodic cleaning of the HVAC system provides multiple benefits including improved indoor air quality for staff, the public and other users of the building. Clean air ducts also improve the efficiency of the HVAC system to maintain a comfortable work environment at a lower operating cost. Industry standards recommend air duct cleaning every five years for office buildings and it has been decades since some of the City Hall air ducts have been cleaned. Even the new HVAC ducts, installed on certain floors during the City Hall renovation project, are now ten years old.
The work under this contract includes cleaning the overhead supply air, ducted return air, two air handlers and nearly 80 terminal units located on the seven floors and mechanical penthouse of City Hall. The work will follow the International Standards developed by the National Air Duct Cleaners Association (NADCA).
Work will be completed in the evenings to minimize impact to municipal operations. Each floor will take about two evenings to complete. The building's entire HVAC system will need to be shut down each evening when work is ongoing. HEPA filtered, high powered vacuums will be used on each floor to maintain a high level of indoor air quality while eliminating any exterior noise in the evenings for nearby residents. DUCTZ of SE Michigan is a member of the NADCA and has the required Category 3 Mechanical Contractors License from the State of Michigan.
