This is a Statement of Work for the replacement of two inoperable geothermal heating and cooling units at the Sabine District Office, located at 5050 TX 21, Hemphill, TX 85948.
The contractor must replace two 5-ton, closed-loop dual inline pump geothermal heat pumps (TRANE model GEVE06011G01ATR0010000100000000000) that are more than 10 years old and no longer functional. Replacement units must match or exceed the existing tonnage and salient characteristics, including performance and capacity. The new units must include a 2-stage scroll compressor in an upflow configuration, a dual flow pump center for water flow and serviceability, and new programmable controls. The units shall not have electric resistance heat. The contractor is responsible for system balancing, connecting to existing air distribution and water circulation systems, purging geothermal system lines, commissioning the system, and ensuring 100 percent operational status prior to demobilization. Additional work includes installing new polymer drain pans plumbed to drain outside the building, removing and disposing of existing units from government property, and providing pleated air filtration (minimum MERV 8 rating). Existing ducting and supply/return piping must not be significantly altered from current configuration. The contractor must provide manufacturer specifications documenting that quoted geothermal units meet or exceed existing unit characteristics as an attachment to the quote. Warranty requirements include a minimum 5-year manufacturer warranty for compressor, parts, and labor, effective from the date of government acceptance and final payment.
