About this file
This is Addendum #3 for a generator replacement project (S-29100-00005968) at SFFC, issued on April 5, 2023, modifying the original Invitation to Bid specifications. The addendum provides two key clarifications regarding electrical work identified in the bid set plans. First, concerning plan note #10 regarding undersized load-side conductors from a fused switch, the contractor was originally required to provide separate line items for either replacing existing 400A fuses with 250A fuses or replacing existing line-side conductors with larger gauge wire and conduit. ODOC has elected to proceed with option A, replacing the existing 400A fuses with 250A fuses. Second, addressing plan note #11 regarding a breaker replacement, ODOC has decided not to replace the existing 400A/3-phase breaker with a new 600A/2-phase breaker as originally specified. Instead, the existing 400A/3-phase breaker will remain in place and be utilized as a 400A/1-phase breaker to accommodate the alternator conversion from 3-phase to 1-phase operation.
This addendum constitutes a material change to the original Invitation to Bid and requires authorized signatures and acknowledgment from all bidders by the bid closing date. Failure to sign and return the addendum with bids may result in bid rejection. The addendum references two supporting documents but does not specify revised pricing, timeline adjustments, or other contractual modifications beyond the technical clarifications noted.
