Greenhouse Specifications.docx

This is a Greenhouse Specifications document detailing the equipment and structural requirements for the USP Lee Greenhouse Project. The project encompasses a 41.5' x 72' greenhouse structure with a 12' x 24' lean-to classroom addition, designed to support hydroponics systems for growing tomatoes and peppers. The greenhouse frame utilizes 4" x 4" square 11 GA tubing posts on 12-foot centers with 2" x 3" rectangle 14 GA tubing bows, engineered to withstand 90 mph wind loads and 10 psf ground snow loads under Risk Category I specifications. The structure includes 14 GA galvanized gutters, a 10-foot gutter height, and sealed structural and foundation drawings.

The project requires comprehensive climate control and ventilation systems, including two 48" exhaust fans, one 24" box exhaust fan, six 18" horizontal air flow fans, a 30" shutter with motor, and a 6" PVC evaporative cooling system with 35-foot cooling cell framing. Heating is provided by a 400,000 BTU natural gas heater, with climate control managed through a Climate Boss Controller. The covering system utilizes a twin wall polycarbonate roof and side/end coverings (8mm polycarbonate twin wall kits). The hydroponics component includes a hydroponic and Bato bucket system with flow water infrastructure. The greenhouse frame, welded base plates, structural components, and all hardware packages are included in the specification requirements for this Department of Justice Bureau of Prisons project at United States Penitentiary Lee County.
