Provide and Install 75kw Generator Questions and Answers_Final.pdf

This document is a Questions and Answers (Q&A) file addressing clarifications for a federal contract opportunity to provide and install a 75 kW generator at a Coast Guard facility (Building 43).

Contract Specifications and Technical Requirements: The procurement is classified as a supply purchase with incidental installation, and prevailing wage rates do not apply. The required generator rating is 65 kW/80 kVA minimum, three-phase, 120-240V, 60 Hz diesel-powered unit, though the scope initially referenced 75 kW. The service size is 100 Amperes 120/240V with an existing Type-3R enclosure. The existing foundation pad measures approximately 116" x 118". The new generator must connect to Building 43's electrical system via a new automatic transfer switch (ATS) rated 100 Amperes NEMA 3R-A and meeting NEC standards. Functional start-up and operational testing of the generator and transfer switch are acceptable; no certified resistive load bank testing is required. The generator is intended for outdoor installation and will operate as an emergency standby unit for less than 100 hours per year. The fuel system should be contained within the newly installed system. The electrical configuration is a 4-wire high-leg delta system. The Buy American Act applies to this requirement.

Permitting, Environmental, and Administrative Matters: The contractor is responsible for filing the initial BAAQMD (Bay Area Air Quality Management District) permit, which will subsequently transfer to the Coast Guard for maintenance. The generator must comply with federal, California, and local air-quality BAAQMD standards; either a Tier 2, Tier 3, or Tier 4 engine is acceptable for this emergency use category. No pre-bid meeting or public bid opening will be conducted. Photographs, nameplate data, and existing equipment specifications have been provided to support contractor proposal development.
