MAJOR ACQUISITION BUYING OFFICE

I. GENERAL

A. DESCRIPTION OF WORK/SCOPE: The contractor shall furnish all personnel, equipment, tools, materials, supervision, and other items and services necessary to decommission, dispose of and replace the existing water-cooled Geothermal Heat Pumps, Circulating Pumps, Frequency Drives and Building Management System. All work required by the project documents shall be accomplished by the contractor even though minor items required may not be specifically mentioned. These specifications describe requirements for a geothermal system and associated components to the system. The system shall be designed to maintain temperature and relative humidity conditions within the building.

BACKGROUND

This project is located in the Visitor Center of the Fort Smith National Historic Site. The project is to remove and replace twelve (12) outdated water-cooled geothermal heat pumps, two (2) circulating pumps, two (2) Frequency Drives as well as a Tracer Summit Control System which maintains a consistent tempered environment for visitors and employees. Eight of the twelve HVAC units to be replaced are located in the attic of the Visitor Center which has limited access and will require use of hoists, lifts or other means to complete the installation process. The current units were installed in 2000-2001; the expected life span is 10-15 years after installation. Replacing current units at the maximum end of the expected service life will reduce repair costs and provide for a more efficient operation and uninterrupted service. This project takes place in and around historic building and adherence to historic preservation guidelines must be observed. New HVAC units and components are to be installed in existing footprints with no alteration to historic fabric. For specific standards, guidelines and other historic preservation related information involving to this project, refer to: http://www.nps.gov/history/standards.htm and http://www.achp.gov/nhpp.html
