General Information

Haines Dalton Cache Land Port of Entry Mile 40 Haines, AK 99827

AK0521AB

The United States General Services Administration requires the replacement of 400A electrical automatic transfer switchgear (ATS) at Haines LPOE building. The existing transfer switchgear has failed and will not automatically switch between utility power and backup generator power. This creates a condition for our building in the winter, that without manual intervention, should the power go out at the building, emergency power is not started or transferred to the backup generator, risking the building of freeze-up during the winter, and interrupting the tenant’s mission at the site. There is only one O&M staff member at the site, and it is impossible for them to be at the building 24/7 through the winter. The intent of the emergency work is to be accomplished before the hard days of winter set in at the site.

This project shall be accomplished during or after normal working hours of 7:00 AM to 5:00 PM weekdays, except Federal holidays. Contractor shall schedule the work in writing at least 5 business days in advance with the GSA Project Manager (PM).
