Waste Water Facility HVAC Upgrades

To award the HVAC Upgrades contract in the amount of $896,956 to Monadnock
Building Company of Jaffrey, NH. Funding will be through: Department: 169 -
Wastewater; Fund: Wastewater; Activity: AC & Air Handling.

Monadnock Building Company Cost Proposals

The HVAC system at the Nashua Wastewater Treatment Facility was installed between
1972 and 1988. These are the original units and are in need of replacement due to age
and functionality. Some of the units are not working causing the plant to supplement heat
in the winter with electric heaters. These systems have exceeded their useful life.

The project was originally sent out to bid; however, due to the large amount of work in
the state, combined with the low number of qualified vendors, only 2 bids were received.
The low (base) bid was for $1,055,000, which was much higher than the consultant,
Wright Pierce, had estimated. After careful consideration, it was the recommendation of
the consultant that we reject both bids and negotiate costs directly with a separate vendor,
Monadnock Builders. Monadnock had expressed a great deal of interest in the project,
but in the end found themselves unable to bid due to the bond requirements.

By negotiating directly with Monadnock Builders the City can structure a contract with
them that will allow them to meet their bonding requirements, while the City receives a
more affordable project.

At the City’s request, Monadnock broke their costs into 4 proposals to allow for easier
tracking and payment of completed work.

Proposal 1 - RTU 1 & 2 $566,717
Proposal 2 — Girt Building modifications $73,718
Proposal 3 -RTU 2, SAHUI, split system for electric room $100,725

Proposal 4 — Boiler room, Control Bldg Offices, ceiling modif’s $155,796
Total: $896,956

References of Monadnock Builders were checked and found to be favorable for this
project.
