PROJECT TITLE:

Replace compressor for Trane Chiller

Performance Work Statement

SECTION C. PERFORMANCE WORK STATEMENT

C.1. INTRODUCTION

The Wetland and Aquatic Research Center (WARC) is located in a fenced in area consisting of approximately 19 acres of University of Lafayette Louisiana (ULL) property with a total of

107,361 SQ FT of building space. The WARC requires replacement of a new compressor for a

Trane Chiller unit.

C.2. BACKGROUND

The chiller system provides critical cooling to the WARC. Currently the center has two chiller units. During the winter months, only one chiller is needed to supply sufficient air but during the spring/summer months both chillers are required to properly regulate the airflow in the center. When a chiller goes down in summer months the repair is considered an emergency repair. Without this emergency repair the remaining operating chiller unit could fail causing additional repairs.
