STATEMENT OF WORK

TITLE: Walk-in Cooler Condenser and Evaporator Replacement for Sugar Beet Research

1. BACKGROUND:

The Agriculture Research Service (ARS) is the chief in-house agency of the United State Department of

Agriculture (USDA) located on Colorado State University (CSU) campus. The USDA ARS Facility department is responsible for providing an adequate and safe work environment supporting crops research and genetic resource preservation. This facility supports on-going sugar beet research. The project is located at 5021 East

County Road 58, Fort Collins, CO 80524.

2. OBJECTIVE:

The intent of this solicitation is to obtain updated modernization of walk-in cooling units storing sugar beet material for long term storage. This project consists of relocating condenser unit to the north side of building one from the current attic location. The evaporator will be replaced with a new component to assist with keeping temperatures at precise temperature thresholds as requested by research staff performing work with sugar beets. This project will consist of the installation of an advanced KE2 thermostat controller providing better control and energy savings related to upgrade of environmental unit and controls.

3. SCOPE:

3.1. List of milestones during replacement of equipment are listed below:
