The United States General Services Administration requires the demolition/removal of

(2) each fuel oil fired Burnham 3-pass cast iron boilers and replacement with modern higher efficiency units. The antiquated system presently in operation is not capable of adequately heating the entire facility during extreme cold weather cycles. Each of the new boilers must be individually capable of carrying the entire facility BTU heat load during the coldest winter months when outside ambient air temperatures can reach -50’F and colder.

This project shall be accomplished between the hours of 6:00 AM and 8:00 PM and may take place any day of the week to include weekends and Federal holidays. Contractor shall schedule the work in writing with the GSA Project Manager (PM).

Contractor parking at the Service Building is available. Access to the facility requires coordination with the GSA Project Manager in advance.
