About this file

Written by GovTribe AI · Jun 2, 2026

This file contains preliminary electrical construction drawings and specifications for the Motor Controls Center (MCC) replacement project at Goochland High School, located at 2938-I River Road West, Goochland, Virginia 23063. Prepared by Dewberry Engineers Inc. with a project number of 50191062 and dated April 8, 2026, the drawings outline the complete demolition and replacement of existing MCC-1 and MCC-E systems with two new power distribution panelboards (PP-1 and PP-2) rated at 480/277V. The project scope includes removal of existing motor control equipment, installation of combination motor starters on stainless steel racks, new conduit and wiring throughout both the first floor and roof areas, extension of control circuits to the existing Building Automation System (BAS), and associated electrical infrastructure modifications. The drawings reference applicable codes including the 2021 Virginia Uniform Statewide Building Code, 2021 Virginia Construction Code, 2020 National Electrical Code, and 2021 Virginia Energy Conservation Code. The document set includes comprehensive details on demolition plans, new work plans, electrical schedules, riser diagrams, control diagrams, and standard installation specifications, with notation that these are preliminary documents not for construction.

The drawings specify detailed requirements for equipment installation, including the provision of galvanized sheet metal drip pans beneath hydronic piping, waterproof seals for roof penetrations, and concrete encasement for underground electrical conduits. Work coordination requirements include mandatory notification to the engineer upon discovery of discrepancies, field verification of existing conditions prior to construction commencement, and coordination with the owner at least 72 hours in advance of power shutdown activities. New combination motor starters are designated for various loads including multiple pumps, boilers, cooling tower heaters, and rooftop units, with voltage ratings of 480/277V and sizes ranging from Size 1 to Size 5. The project maintains a minimum seven-foot clearance for future equipment replacement and includes provisions for space reserved for future motor drives. All electrical work must comply with working clearance standards as outlined in the drawings, with proper support structures, labeling, and grounding conductor provisions throughout the system.
