Performance Statement of Work

Installation of HVAC System Office Building

Waubay National Wildlife Refuge, Waubay, South Dakota

1.0 Introduction and Overview

Waubay National Wildlife Refuge is a National Wildlife Refuge in South Dakota. "Waubay" means "a place where numbers of birds make their nests" in the Dakota language. The Refuge encompasses 4,650 acres of wetlands, native tallgrass prairie, and bur oak forest that provide a wide variety of nesting habitat for more than 100 species of waterfowl, song birds, and upland game birds as well as 140 additional bird species during migrations. Mammals include species from the ever-present white-tailed deer to the more elusive coyote and the diminutive pygmy shrew. The central location of Waubay National Wildlife Refuge in North America gives visitors the chance to see a mix of eastern, western, northern, and southern species.

Replace the existing HVAC systems at Waubay NWR office and equipment with a properly designed, high efficiency system that can meet proper comfort and environmental control levels within the building.

The office was constructed in 1983 and an addition was built on to the structure in 2004. The office utilizes two separate HVAC systems, one installed in 1983, which has one HVAC unit utilizing a geothermal system with propane backup and one installed in 2004 with two HVAC units utilizing a separate geothermal system. However, the systems are not functioning properly resulting in an extremely inefficient heating and cooling throughout the facility. Portions of the office never receive adequate heating regardless of thermostat settings due to the overall HVAC design. Service technicians have indicated the only way to solve the issue is to install new HVAC system/units. In addition, HVAC units have been repeatedly serviced and have reached life expectancy.

1.1 Scope of Work

Remove existing HVAC Systems installed in 1983 and 2004 (geothermal units) and design / furnish / install a new and appropriately sized system. The new systems should be a 90% energy efficient and include a system to clean the air and kill airborne virus and bacteria (to include Covid 19) such as the GPS Needle Point Bi-Polar Ionization System or an approved equivalent. The Office Building is a single-story building built over a basement with approximately 5,450 square feet with several offices and large conference rooms.

1. The completed system shall be tested for proper operation upon completion of installation. The new HVAC control system shall communicate with all the air handlers, pump, and valves, etc.

seamlessly and efficiently, providing staff a comfortable work environment year-round.

2. The contractor shall be licensed in the state of South Dakota. All work and testing shall be in accordance with the International Mechanical Code (IMC 2021) and International Energy Conservation Code (IECC 2018). Duct work shall be performed in accordance with NFPA90B.

Electrical work shall be in accordance with NFPA National Electrical Code 2017.

3. The contractor shall inspect buildings, perform, and submit load calculations (ACCA Manual N) and confirm that the specified system will be efficient and provide adequate capacity.

4. The contractor shall submit any necessary Architectural, Structural, Mechanical, Electrical or Plumbing drawings in CAD or PDF format to the Project Manager prior to construction or upon request of the Project Manager.
