About this file
This document contains a request for clarification regarding drawings for a project to repair an electrical distribution system at Joint Base Charleston - Weapons Station in Goose Creek, South Carolina. The project involves removing and replacing asphalt, installing a new underground electrical service from a transformer to Building 900, removing existing conductors and conduit from a hand hole to a pole and abandoning underground conduit, and installing a secondary service from the transformer to a new hand hole with compression splices to existing conductors. The engineer provides clarification that drawing ES408 correctly depicts the work, with secondary hand holes to be installed to allow replacement of the electrical secondary within the time limits specified, as outages are restricted to outside normal working hours.
The related federal contract opportunity is a solicitation for the project to repair the electrical distribution system in the B2 Area at Joint Base Charleston - Weapons Station. The single award firm-fixed price contract requires providing personnel, equipment, tools, materials and supervision to complete the work within 270 calendar days. A pre-bid site visit was scheduled for May 6, 2020 at the base visitor control center. The solicitation was issued by the Department of the Air Force Air Mobility Command.

Drawing ES407 – new Electrical Underground service from Transformer to Bldg. 900
Drawing ES408- Existing building 900 riser diagram – Remove existing conductors from new hand hole back to pole. Remove above grade conduit and abandon underground conduit in place.
Drawing ES 408-Bldg 900 Riser Diagram – Secondary service from transformer to new hand hole. Splice new secondary conductors to existing secondary conductors in hand hole with copper to aluminum compression splice.
Conflicting drawings in respect to new EUS to Bldg 900, Please clarify.
Answers from 628th CES
My answer would be to plan on completing the work in the most efficient and cost effective manner. Specifications 01 11 00, para. 1.6.2 and 01 14 00, para. 1.2.5 limit power outages to outside normal working hours (M-F, 7 am – 3:30 pm), so secondary hand holes are usually put in place to accommodate this requirement. If there’s no way that the entire electrical secondary could be replaced in the time limit set forth in the specifications, hand holes will be required.
The original intent was to install hand holes for this reason. Therefore, drawing ES408 would be correct and in congruence with the specifications.
Respectfully, Lawrence J. Pearl, P.E.
Electrical Engineer
Joint Base Charleston-WS
