About this file

Written by GovTribe AI · Dec 20, 2023

This document provides construction documents for HVAC system upgrades at the Wichita Mountains Wildlife Refuge Visitor Center in Oklahoma. The project includes replacement of existing HVAC equipment with new water source heat pumps, energy recovery ventilators, unit heaters, and associated ductwork, piping, controls, and commissioning. Detailed drawings and schedules specify demolition of existing systems, layout and connection details for new equipment, control sequences, and performance requirements. The opportunity was solicited under solicitation number 140FGA23R0017 by the Department of the Interior Fish and Wildlife Service.
