1. Is the duct bank from MH-402 to the pad mounted switchgear existing? Reference attached E10-RFI. No. Duct bank will need to be installed. Duct bank details added to posting.
1. We would like to confirm the design intent of the 13th street feed. The feed will be pulled back from existing transformer to MH-402 and spliced with new cables to the pad mounted switchgear. Then the transformer will be fed with new cables from the switchgear through MH-402 to the new transformer. Please confirm this is the accurate scope of work. This is correct.
1. We would like to also confirm the only excavation required will be at the transformer location. Demo of existing transformer and excavation required to install new transformer pad. Excavation will be needed for concrete duct bank as well.
1. Are there spare wires in MH-402 (manhole)? : No
1. Are there spare conduits in MH-402 (manhole)? : Yes, stub outs only. No existing spare conduits to switchgear from manhole.
1. Are we splicing in MH-402 before routing to the switchgear? : Yes.
1. Is there an existing duct bank from MH-402 to switchgear? No. Contractor will need to install. Duct bank details added to posting.
1. How will temporary power be handled during transformer replacement? : There are currently generators that power crucial buildings and processes when utility power is lost. These generators will be ran during the replacement process and the power changeovers. Contractor will need to give at least 2 weeks’ notice prior to any shutdowns.
1. Does new circuit need to have parallel runs? : Currently, transformer has parallel runs from transformer to switchgear. One single run is acceptable if wire size is available and will fit in 4” PVC.
1. Are there any spares stubbed out from the switchgear? : Electrical Wiring Diagram from 2015 project states that (2) spare conduits should’ve been stubbed out north of new switchgear, 5’ to the north from the incoming line switches. Drawing added to posting.
1. Boring under roadways?: Conduits bored under roadways will not need to be installed in concrete duct bank.
