This is an electrical riser diagram drawing prepared by the State of Michigan Department of Technology, Management and Budget, State Facilities Administration, Design and Construction Division for a facility maintenance project (Contract Order No. 472/LCFMAINTPROJ, Consultant Job No. 20080.00). The document presents two electrical riser diagrams—one showing existing equipment designated for demolition and a second showing the proposed new electrical configuration. The project involves modifications to the main distribution panel (MDP) rated at 2500A serving 120/208V three-phase, four-wire service, with work including the removal of a 50A breaker and installation of a 60A three-phase breaker to feed new equipment. The scope includes installation of new switchgear and breakers tied into the existing MDP, with the contractor required to match existing switchgear manufacturers and provide space for four spare 400A breakers. The project also requires installation of a new 1200A breaker in existing switchgear with arc flash reduction capability and coordination with the switchgear manufacturer.

The electrical modifications involve multiple distribution panels located in basements and attics, with connections to new rooftop units (RTU-1 through RTU-5) and existing HVAC systems, emergency power panels, UPS panels, and information system panels. New feeder circuits are specified with wire sizes ranging from 6 to 500KCMIL copper conductors with appropriate ground wires and conduit sizes. The project requires proper grounding integration with existing systems including water pipes, building steel, and footing steel grounds. The drawings were issued for construction on 9/14/2023 and reference comprehensive mechanical, electrical, and architectural sheet sets for the full project scope. The document was prepared by consultant JFS under the supervision of Director Adam P. Lach, RA, with drawing prepared by JKB.
