HVAC Alteration/Renovation Southeast Watershed Research Laboratory, Building 31

PURPOSE______________________________________________________________________

The HVAC system(s) of the Southeast Watershed Research Soils Lab functions to support a single-pass air arrangement. However, due to a change in the type of research being conducted in this lab, single-pass air is no longer required. Furthermore, the current HVAC equipment has exceeded its expected service life and performs inadequately causing difficulties to properly heat, cool, and dehumidify both lab and office spaces. This document details the requirements USDA-ARS will need to accept a successfully outsourced HVAC alteration/renovation at this lab.
