SWRP Switching Station Replacement (CMAR contractor)

The City of Columbus is seeking a Construction Manager at Risk (CMAR) to replace three aging 15 kV switching stations at the Southerly Water Reclamation Plant, relocate the Division of Power sub‑station, and upgrade the plant’s internal power‑distribution system. The scope includes full pre‑construction services, detailed electrical and civil design, procurement coordination, and oversight of construction through a Guaranteed Maximum Price (GMP) contract. The effort will span roughly 12 months of design development followed by a multi‑year construction phase, with the CMAR responsible for managing subcontractors, ensuring compliance with a broad set of local, state, and federal codes, and maintaining plant operations throughout the transition. • Replace three 15 kV switching stations and install a new main switching station (MSS). • Relocate the Division of Power sub‑station within the floodplain and redesign power‑distribution to a radial feed system. • Provide comprehensive electrical, mechanical, structural, and civil engineering design, plus environmental and geotechnical investigations. • Manage procurement, subcontractor coordination, and construction under a CMAR contract with a GMP, ensuring adherence to Ohio building, electrical, mechanical, plumbing, and NFPA standards.
