Description of Work: This is a design-bid-build (DBB) construction project to remove the existing 3.75MMBTU oil fired boiler and replace with two (2) w.75MMBTU natural gas units. The project will also replace pumps, piping, expansion tank, unit heaters, and hot water coils associated with the new system. The contractor will be responsible for incorporating any changes to the existing Delta Controls Building Automation System (BAS,) including but not limited to modifying control points, programming, graphics and adding any required controllers, hardware and devices. The BAS provides efficient and safe operation of the building HVAC system, by monitoring and controlling the boiler, temperatures, valves, pumps and fire alarm operation.
Designer must provide installation phasing plans for approval. Phasing plans must segment the installation in each of the attics above the wings and pavilions. To the maximum extent feasible, phasing needs to minimize the amount of time a specific area of the building is without sprinkler protection. When attics are without sprinkler protection for more than 24 hours, contractor shall provide a fire watch. In wings where building occupants will need to be moved in order to access the attic for demo and to install attic sprinkler systems, a six week notice is required and further coordination with building tenant will be needed to ensure space is cleared for work. *The bid list for this project may be incomplete.
