This government document contains the 100% submittal design drawings and specifications for the envelope and HVAC modifications of Building 63, located at the U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) facility on Old Cutler Road in Coral Gables, Florida. Prepared by Clark Nexsen under USDA contract number 12639521D0050 (modification P00001), the project focuses on upgrading the building’s thermal envelope and mechanical systems. Key elements of the project include replacing the existing air-cooled chiller, chilled water pumps, and Direct Digital Control (DDC) system with a new BACnet control system. Additionally, the project details structural framing, roof replacements, and supplemental fastening of existing roof sheathing to comply with the 2023 Florida Building Code. The design plans outline a phased construction sequence to minimize disruptions and maintain building egress and environmental controls within the active, occupied laboratory and office facility. Architectural, structural, mechanical, electrical, and life safety plans are indexed to guide the comprehensive renovation.

This federal Statement of Work (SOW) outlines a project to renovate the envelope and HVAC systems of Building 63 at the USDA Subtropical Horticulture Research Agricultural Research Service (ARS) Station in Coral Gables, Florida. The facility's approximately 6,000 square feet of lab and office space are experiencing severe condensation, water damage, and high humidity levels (70% or higher). Based on designs and solutions proposed by Clark Nexsen, the selected contractor will furnish and install all labor, materials, and equipment to renovate the roof, HVAC, building automation system (BAS), and chiller. The scope of work is divided into preconstruction and construction services. Preconstruction duties include site investigations, submitting itemized proposals, providing schedules, and delivering product data submittals and shop drawings. Construction duties involve participating in progress meetings, obtaining warranties, providing user training, transferring as-built CADD and PDF drawings, and completing punch list items. Additionally, the contractor must submit a comprehensive code analysis to ensure compliance with federal, state, and local building codes. Because the USDA will maintain full occupancy of the building during construction, the contractor must coordinate operations to minimize disruptions, maintain emergency exits, and provide a 72-hour notice prior to activities affecting daily operations. Submittals and closeout documentation must be distributed electronically to the designated project contacts, including the Contracting Officer, Engineering Project Manager, and Facility Manager.
