Written by GovTribe AI · Jun 10, 2024

This document contains the drawings and specifications for the electrical upgrade of Building 4156 at Dugway Proving Ground in Utah. The key details are:

The project consists of relocating and replacing the transformer at Building 4156, performing approximately 100 feet of trenching and new conduit, upsizing the generator, replacing the primary switchgear and automatic transfer switch. The magnitude of construction is between $1,000,000 and $5,000,000. The procurement will be a design-bid-build (DBB) contract, issued as a total small business set-aside with proposals due around August 12, 2024. The North American Industry Classification System (NAICS) code is 238210 - Electrical Contractors and Other Wiring Installation Contractors, with a $19 million small business size standard. The Product and Service Code (PSC) is anticipated to be Z2AA - Repair or Alteration of Office Buildings. A pre-proposal conference and/or site visit may be conducted. The solicitation documents include drawings and specifications for the electrical upgrades, which cover demolition plans, site plans, power plans, one-line diagrams, switchgear layout, and details.
