## Description

The facility located at the USDA Subtropical Horticulture Research Agricultural Research Service (ARS) Station has approximately 6,000 square feet of lab and office area. The ductwork is collecting condensation and causing water damage. The HVAC system consists of one air-cooled chiller, associated pumps, and two variable air volume air handling units. The humidity in the labs was tested and determined to be higher than the acceptable range (70% or higher). A&E firm Clark Nexsen provided retro commissioning with TAB services and proposed solutions for the condensation problem, as well as designs for the renovation of the roof, HVAC, BAS, and chiller. Solicitation documents are posted below.

**NOTE:** The drawings and specifications below are the A&E's 100% submittal to USDA-APHIS. When internal reviews are complete and returned, the A&E will finalize and send us the stamped, for-construction drawings and specs, at which point they'll be posted here.

Amendment 1 and the final construction documents are posted below. Site visit attendance list is posted below. An RFI log is posted below.

Amendment 2 is posted below. It extends the closing date for receipt of proposals.

Amendment 3 is posted below. It corrects the NAICS code. RFIs and responses also posted. A few more RFIs and responses are in a document posted below, along with a corresponding drawing.
