About this file
This document provides maps and plans for multiple building HVAC improvements at the Great Onyx Civilian Conservation Center in Mammoth Cave, Kentucky. The maps depict proposed locations for new mini-split heat pump systems to replace existing split systems serving dormitory buildings. Details include installing outdoor condensing units on wall brackets or concrete pads with routing of refrigerant lines and low-voltage wiring. Indoor units will be wall-mounted above windows with condensate drains extending to the exterior. New branch circuits from an existing 400A, 208/120V 3-phase panelboard will power the new systems.
The related federal contract opportunity is a solicitation for Multiple Award Indefinite Delivery/Indefinite Quantity contracts for facilities construction and maintenance services at Job Corps centers located in several southeastern states. The NAICS code is 236220 for commercial and institutional building construction. The small business size standard is $45 million. Individual IDIQ ceiling is $5 million over five years or until the shared ceiling is reached. Services may include new construction, additions, alterations, roofing, plumbing, HVAC, electrical and other trades. The contracting agency is the USDA Forest Service Job Corps.
