HVAC REPAIR AND INSTALLATION WORK

At Hatchery Building and Old Office/Garage

NORTH ATTLEBORO NATIONAL FISH HATCHERY

North Attleboro, Massachusetts

1.0 Introduction and Overview

North Attleboro National Fish Hatchery (NANFH) requires heating, ventilation and air condition

(HVAC) work at the Hatchery Building and the Old office / Garage building as described below.

The Hatchery Building system shall be repaired, while the Old Office/Garage Building system shall be removed and replaced with mini split ductless systems.

A. The Hatchery Building currently has a Weil-Mclain WTGO-5 Boiler with 6 Simplex

Grinell model # 44ER10T12 Hydronic unit heaters. The boiler is functional but the unit heaters do not disperse heat throughout the spaces. Recent work includes new air vents at all unit heaters and piping repairs at one of the unit heaters.

B. The Old Office/ Garage currently has two Texaco Fuel Chief oil fired Warm air furnaces that are beyond their service life and unrepairable due to age and availability of parts.

Replacement of the two systems is required. Install suitable Mini split Ductless AC/Heat pump systems to provide seasonal comfort to the 3 workspaces in the Building, per the

HVAC requirements specified in this document.

1.1 The work is located at 144 Bungay Rd North Attleboro, MA 02767.

1.2 Scope of Work For The Hatchery Building

Interested vendors are encouraged to visit the hatchery building during the scheduled site visit and provide a proposal to repair the heating system, including furnishing and installing all the necessary replacement parts and components to have a properly functioning system. The mechanical contractor shall make the specified repairs

/replacement parts, and test the systems for proper operation.

Currently there is a Weil McLain WTGO-5 Boiler with Beckett oil burner, piped to a

Taco 1600EAE8 4.5 recirculation pump that flows water to 6 Simplex Grinnell Hydronic unit heaters model# 44ER10T12. The Boiler operates as it should and provides proper temperature to the system. The associated piping, valves, controls and recirculation pump do not distribute the heat to the Hydronic heater units. The system has a supply temperature of 160 degrees F and a return temperature of 60 degrees F.

The existing circulator pumps and valves shall be inspected by the contractor for proper operation, and replaced if they are found to be defective.

Provide all the required components, including but not limited to ball valves, aqua stat controls, piping, thermostats and all other components, for all the necessary repairs to return the system to fully operational status.
