About this file
This document package includes a mechanical schedule and specifications for an administrative building project, as well as details of a related federal contract opportunity posted by the Department of the Army Materiel Command Mission and Installation Contracting Command Fort Hood.
The mechanical schedule outlines requirements for an air handling unit, diffusers, return grilles, unit heaters, exhaust fans, and louvers to support the administrative building. It also includes specifications for dedicated split systems serving individual rooms. The federal contract opportunity seeks bids to construct the administrative building to replace existing temporary trailers at Shorthorn Airfield, North Fort Hood, Texas. The project is set aside for small businesses with a size standard of $36.5 million. The estimated construction price range is between $1 million to $5 million. The selected contractor will be responsible for all labor, materials, equipment, and work to complete the project in compliance with all applicable laws and standards.
