The project scope consists of demolishing existing switchboards and structural concrete pads;
decommissioning conduits and wire; and replacing all with new structural infrastructure,
conduits, wires, switchboards, and associated equipment. The switchboards will be upsized from
existing capacity of between 400 and 600 amps to 1200 amps for the smaller switchboards and
from 2500 Amps to 4000 Amps for the main switchboard for future capacity needs (e.g., EV
chargers, shore power). This project will not increase the electrical load at the site at this time.
The estimated electrical equipment procurement is $1,800,000 with total estimated project costs
of $6,440,000. Funding for this project was included in the 2023 capital budget and plan of
finance.
Scope of Work
The following electrical equipment will be replaced:
1. Switchboard 4SP and 2SPN (service entry to site)
2. Switchboard 4W and 2W (wharf)
3. Switchboard 4P and 2P (NE side of Building A-1)
4. Switchboard EY4 (east side of Building A-1)
5. Switchboard SEY4 (lighting connection for east lot)
6. Switchboards EY4 and SEY4 will be consolidated with 4P and 2P in one location that has
better access. Additionally, this will eliminate a stormwater intrusion point at EY4.
Site work:
1. Provide new conduits and conductors from Seattle City Light to new MIC main distribution
switchgear.
2. Provide new conduits and conductors from new MIC main distribution switchgear to:
a. New electrical switchboard at Mooring Pier
b. New electrical switchboard at Wharf
