AI Contract Overview

The contract involves the replacement and upgrade of an aging power distribution system within the B002 Klystron Gallery and several associated sectors at SLAC. The existing system includes original 480V, 400A distribution panels without main breakers that were installed over 60 years ago. Five feeders supplying these panels failed insulation resistance tests and were temporarily replaced with overhead cables, which are considered less safe and reliable than permanent feeder conduits. The primary scope includes replacing specific distribution panels in Sectors 23 and 27 with new government-furnished 480V, NEMA 1, 400A main panelboards rated at 65kAIC, along with the installation of new overhead feeder conduits from K-12 and K-14 substations. These conduits will also incorporate expansion and deflection fittings at seismic joints to accommodate structural movements. Additionally, the contract outlines options for further replacement of distribution panels and temporary cords in Sectors 11, 13, and 15. The work is set to take place in Menlo Park, California, and is aligned with NAICS code 238210, which covers electrical contractors and other wiring installation contractors. The points of contact for this project include Kris Faulkner, Team Lead for Construction & Projects, reachable via the provided email. This upgrade aims to enhance operational safety and system reliability by eliminating aging equipment and temporary feeder solutions.

Full Description

The existing power distribution system in B002 Klystron Gallery was built more than 60 years ago. In the Sectors 11, 13, 15, 17, 19, 21, 23, 25, 27, and 29 SLAC has original 480V, 400A, 14kAIC DPA distribution panels without main breakers. These panels are fed from 12.47kV-480V K-Substations via feeders in underfloor conduits. During the last years five of such feeders failed the insulation resistance test and were replaced with temporary overhead portable cables. Such temporary configuration is not as safe and reliable as permanent feeders in conduit. The base scope is to replace existing DPA panels 4P23C in Sector 23, 4P27C in Sector 27 with Government Furnished new 480V, NEMA 1, 3-wire, 400A-bus, 400A Main, 65kAIC panelboards. This upgrade includes new 480V feeders from Substations K-12 and K-14 respectively to be run in overhead conduits. At each building seismic joint the new conduits shall be provided with expansion/deflection fittings. There also three more options to replace DPA panels and temporary cords in sectors 11, 13, and 15.
