Generator Installation
Parks, Culture & Recreation – Library Building
INTRODUCTION
The City of Unalaska requests proposals from qualified contractors for the installation of a backup
generator outside the Unalaska Public Library building. The project includes all necessary electrical work,
site preparation including excavation and backfill, and forming and finishing of a concrete pad for the
generator.
OVERVIEW
The City has a Generac SD050 generator with a level 1 sound attenuated enclosure and would like to hire
the selected contractor to install it on the southeast exterior of the library building, near the current
heating fuel tank. The city will deliver the generator to the site prior to installation. The generator includes
a weather protected enclosure, and this project will not require building a separate structure to house
the generator.
The project will include installation of the generator, including all electrical connections; preparation of
the site, including excavation and pouring of a concrete pad; compliance with all relevant building codes,
permits, and regulations; and commissioning and testing of the installed generator with City of Unalaska

in place or pre-poured.
Installation and Electrical Work
• Installation of all necessary electrical equipment required to support the generator system,
including wiring, conduit, panels, grounding, and interconnections to the existing electrical
system.
• Installation of an Automatic Transfer Switch (ATS) capable of seamless transition during power
outages.
• Coordinating with City of Unalaska staff for testing and ensuring full operational readiness.
Project Completion
• All systems, including generator and electrical components, must be fully tested for performance.
