Title
Resolution to Approve a Contract with CSM Mechanical LLC, for the Installation of a Secondary Chiller Unit in the Guy C. Larcom City Hall Building ($160,923.00)
Memorandum
We recommend your approval of the attached resolution authorizing a contract in the amount of $160,923.00, with CSM Mechanical LLC, for the installation of a secondary chiller unit at City Hall. The project involves the supply and installation of a new rooftop chiller unit at City Hall to supply cooling air to the building’s HVAC system. The building currently has one large chiller unit which is old, requires extensive maintenance and is difficult to repair as parts are becoming harder to obtain. If the unit goes down, the entire building has no cooled air. In addition, the large chiller unit is not responsive to the rapid change in temperatures that happen in the spring and fall.
The new chiller unit will have about two thirds the capacity of the old unit. This unit will run as the primary unit in the spring and fall when the cooling needs are less demanding, thus reducing the run time (including the frequent stops/starts) on the old chiller unit which should help to extend its life. If the older unit breaks down during the peak summer season, the new unit will at least be able to provide some cooling air. The long term plan is to replace the old chiller unit with a second smaller capacity unit running in conjunction with the new chiller unit proposed in this resolution.
The project was originally bid under ITB-4313 but bids came in higher than the available budget so all bids were rejected. The scope of work was reduced and the project rebid under ITB-4318. Bids were received from five contractors on February 4, 2014. Staff evaluated the bids and determined that the prices were competitive and recommends that CSM Mechanical LLC, Fenton MI, as the lowest responsible bidder, be awarded the contract. The bid tabulation is attached.
In addition to the base bid, we have include...
