Provide 20 percent spare capacity for load growth unless 20 percent spare capacity would require a significant power distribution system upgrade. In those special cases, provide as much spare capacity as the existing system can supply.  \nField verify the existing installation and/or site. Do not rely solely on the existing drawings and/or site surveys. As a minimum, field verify the quantities, sizes, ages, conditions and spare capacities of the following:  \n• Power ducts, manholes, services to the building and unit substations.  \n• Panels, circuit breakers, disconnect switches, motor controls, raceways and wiring.  \n• Interior and exterior lighting, switches and receptacles.  \n• Grounding.  \n• Telecommunications ducts, manholes, rooms and services to the building.  \n• Fire alarm, security, card access control, audio/visual and other special systems.  \nCoordinate with the Design Manager to obtain recent historical information from the following U-M departments:  \n• Key plans and electrical risers from AEC.  \n• Electrical usage, primary system and unit substation information from the Plant Utilities and Plant Engineering (UPE) Department.  \n• Existing condition information from the Facility Condition Assessment Program, the Facility's Manager and the Plant Region maintenance personnel.  \n• Fire alarm and security system information including fire alarm drill results from the Plant Fire Protection Shop and the Department of Public Safety and Security.  \n• Card access control system information from the Plant Key Office.  \nShow all known below grade, below floor and in-floor utilities that will be impacted by the project's work.  \nUse existing spare circuit breakers or existing spaces whenever possible. If necessary, combine existing lightly loaded circuits to free existing circuit breakers for the new loads. Tap buses only with the approval of the Plant UPE Department. Coordinate with the Design Manager before adding a new unit substation.  \nNumber electrical panels and devices in accordance with U-M Standard Detail 260500001. Match the existing installation whenever possible and practical.  \nLocate equipment requiring routine maintenance so it is easily accessible.  \n• Installations shall not require the use of a lift or scaffolding, or the removal of other infrastructure, for routine maintenance.  \n• For rooftop equipment with control panels, motor starters, disconnects or motors mounted over 6 feet above roof level and requiring routine maintenance, arrange for the Architect ","cbCaii5Iac2GbvDs","https://ap.wps.com/l/cbCaii5Iac2GbvDs","pdf",85391,"English","# Scope\n# Related Sections\n# Design Requirements\n## Power distribution and arc-flash limits\n## Spare capacity and future load growth\n## Field verification and coordination\n## Access, layout, and code/safety compliance\n# Short Circuit, Protective Device Coordination and Arc Flash Hazard Studies","[{\"question\":\"What must be prepared under the electrical scope?\",\"answer\":\"Prepare the project’s electrical design and associated contract documents following the design guidelines, program documents, and within the construction budget.\"},{\"question\":\"What arc-flash hazard limits are required for different equipment categories?\",\"answer\":\"Design the power distribution system so required PPE for examining, adjusting, servicing, or maintaining energized equipment is Category 4 or less at unit substations and switchboards, and Category 2 or less at panelboards and similar equipment.\"},{\"question\":\"What studies are required for new or replacement power distribution systems?\",\"answer\":\"Perform a preliminary short-circuit study and protective device coordination study to establish electrical equipment ratings, including checks for equipment provided by others and special handling for interactive power sources.\"}]","COMMON WORK RESULTS FOR ELECTRICAL - Scope, Design Requirements, and Studies | PDF",25]
