Request for Proposals

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

staff.

SCOPE OF SERVICES

The selected contractor will be responsible for:

Site Preparation and Concrete Pad Installation

• Preparation of selected area by removing any debris, vegetation, and unsuitable material to

ensure stable ground.

• Contractor will furnish a concrete pad capable of supporting the generator, sized 10’11” X 6’2”

(based on spec sheet for Generac SD050 with sound attenuated enclosure). Pad may be poured

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.

• Contractor must provide City of Unalaska staff with training on generator operation.

• All construction debris, excess materials, and temporary materials must be removed from the site.

• All disturbed landscape must be returned to the original condition.

PROPOSAL REQUIREMENTS

Interested contractors must submit a proposal that includes:

• Cover letter expressing interest in the project and identifying the respondent, individual and

company name, contact information including physical and mailing address, email address and

telephone number, and a listing of key staff
