Appendix_C.1_-_Secondary_Transformer_List.xlsx

This is a Secondary Transformer List appendix document prepared for the City of Seattle's Lower Duwamish Waterway (LDW) Polychlorinated Biphenyls (PCB) Sampling project. The document appears to be a supporting exhibit that catalogs secondary transformers relevant to the PCB sampling initiative, likely identifying equipment or infrastructure locations that require sampling or monitoring as part of the environmental assessment effort. This appendix serves as a reference tool for bidders responding to the City of Seattle's solicitation, which requires proposal submissions by 4:00 pm on Wednesday, August 26, 2026, with questions accepted through the e-procurement portal at https://procurement.opengov.com/portal/seattle until 4:00 pm on Wednesday, August 19, 2026.

The Secondary Transformer List functions as a technical specification document that bidders must review to understand the scope and scale of the PCB sampling work. The specific contents of the transformer inventory, including quantities, locations, and characteristics, would inform bidders' project approaches, resource requirements, and cost proposals. This supporting document is essential for bidders to develop accurate and complete proposals that address all identified secondary transformers within the Lower Duwamish Waterway project area.
