Electrical Construction IDIQ Contract for Repairs, Renovations, and Alterations to Facilities and Utilities

Contractor shall provide all labor, materials, equipment, transportation and supervision necessary to perform various electrical task orders: - Provide, or modify, electrical branch circuits/feeders from 120/277V volt single phase up to 208/480 volt three phase, utilizing EMT, rigid conduit, liquid tight conduit and wiremold (4000 and 6000 series) raceway systems. - Provide low voltage (600V and less): Equipment: transformer, switchgear, motor control centers, panelboards, motor starters, switches and disconnects(safety) switches, motors, , bus duct switches, wiring devices, and various other electrical equipment and devices. - Provide medium voltage (600V and higher): medium voltage transformers, medium voltage motor control centers, switchgear, power and energy monitoring, protective relays, busway, load break switches, arrestors, motor starters, and vacuum switches. - Provide lighting (120 V to 277 V): fluorescence lighting including re-lamping and ballast replacement and LED replacements. - Provide life safety systems: fire alarm (JCI – Simplex/Grinnell), exhaust fan/fume hood interlock, gas monitoring, toxic gas systems, and laser safety interlock systems. Provide alternate electrical power: uninterruptible power systems, generators, automatic/manual transfer switches and solar systems. - Provide temporary generators, cables and interconnections to NIST facilities. - Provide exterior (medium and low voltage) power distribution systems: manhole, hand holes, concrete duct banks and conductors to include splices. Trouble shoot, identify, and repair electrical faults and problems for low voltage and medium voltage systems. Work from building plans, blueprints, wiring diagrams, engineering drawings, and electrical O&M manuals to plan and lay out the routing, placement type, size, gauge, balance, load, continuity, and safe operation of electrical lines, circuits, systems, equipment, and controls.
