About this file
This is an electrical power and communications plan for a Career & Technical Education Improvements project at Van Buren Intermediate School District in Lawrence, Michigan. The document is a detailed architectural drawing (Sheet E2.2.1A) depicting the Unit 'A' First Floor Power & Communications Plan for a welding lab facility. The plan specifies electrical infrastructure including multiple receptacle types (GFCI, 15-20R, 6-50R, 20-30R, and 6-20R receptacles) distributed across various spaces such as welding stations, lab areas, offices, storage, and support rooms. The drawing identifies numerous electrical loads and branch circuits, with specific homerun designations to welding bus bars (Welding-West, Welding-East, and Welding-Center), each with corresponding disconnect switches and amperage ratings (50A, 60A, and 20A). Key deadlines referenced include bids and construction on 05.14.2026, with addendums issued on 05.28.2026 and 06.04.2026.
The electrical plan incorporates specialized infrastructure requirements including dedicated 20-ampere branch circuits with breaker lock-on accessories for smoke dampers, fire alarm duct smoke detectors, and addressable relay systems for damper interlock operations. The document mandates tamper-resistant receptacles per NEC 406.12 specifications and establishes designated cabling pathways reserved exclusively for Division 27 communications and Division 28 safety/security cabling, with separate independent pathways required for control cabling. Electronic door hardware power supplies must be consolidated at central locations adjacent to access control equipment and connected to dedicated standby power systems. The plan includes provisions for future welders with 60-ampere disconnect switches, a dust collector control panel with sensor connectivity, and data drops for clock installations throughout the facility, all requiring compliance with applicable fire code and NEC standards.
