D5 TRAFFIC OFFICE INSTALLATION OF POWER POLES

• Installation of four power poles for 10 cubicles and installation of 120 V subpanel

Project overview

• Provide and install four (4) power poles to serve approximately ten (10) cubicles. Each cubicle will have receptacles and raceway for low-voltage/data as required by IT (if applicable).

• Provide and install a new 120 V subpanel (size to be determined by load calculation) fed from the building main distribution. Balance circuits and provide required overcurrent protection, grounding and labeling.

• All work shall comply with the latest NEC and local codes, and to pass required inspections.

Scope of work /contractor responsibilities

• Perform field verification of existing conditions, main panel capacity, and routing.

• Perform complete electrical load calculation per NEC to size subpanel, feeder, and branch circuits.

• Obtain and pay for all permits and schedule/coordinate inspections. N/A

• Furnish all labor, materials, tools, equipment, transportation, and supervision necessary for a complete installation.

• Install four power poles including internal raceway, branch circuit wiring, receptacles, and flanges for communications if requested.

• Install a new 120 V subpanel with required main/feeder breakers, neutral/grounding bus, grounding electrode conductor, and bonding per code.

• Provide wiring from subpanel to each pole and branch circuit terminations, including conduit, raceway, junction boxes, and fittings.

• Perform testing and commissioning and provide as-built drawings, test reports, permit sign-offs, and O&M documentation.

• Coordinate with other trades (furnish routing, cut-ins, ceiling work) as required.

Contractor responsible for protecting finished surfaces and cleanup.

Design & installation details (typical — to be finalized after field verification)

• Power poles:

• Quantity: 4 power poles placed as indicated on floor plan (owner to provide desired locations).

• Each pole shall contain enough raceway to serve adjacent cubicles (minimum one 2- 1/2" internal raceway or as specified).

• Provide standard mounting and floor penetration system per architect/owner requirements.

• Provide duplex receptacles per cubicle locations: minimum one duplex per cubicle plus one dedicated at power pole for equipment as requested.

• Receptacles: specification to be standard commercial grade 20A 125V tamper resistant duplex . Install isolated ground receptacles where required for computer/IT loads if requested.

• Outlet placement per layout: at each cubicle work surface height and at top/bottom of pole as required for equipment.

• Include identification/labeling on each pole circuit.

Subpanel:

• Provide 120 V subpanel located where indicated on drawings (or within X feet of main per field conditions). Size to be determined by load calculation; contractor to submit sizing and single-line diagram for approval prior to purchase.

• Typical recommendation (example only): a 60 A, 120 V subpanel with 6–12 spaces (final sizing pending load calc) — contractor must verify actual load and main panel available capacity.

• Feeder conductors: copper conductors in conduit size Overcurrent protection: feeder breaker in the main panel sized per feeder ampacity; branch circuit breakers sized per branch loads (20A general branch circuits typical for cubicle receptacles).

• Provide neutral and ground bus arrangement per code; bond as required.

• Provide panel labeling and directory.

• Branch circuiting recommendation (example: finalize after load calc)

• Provide 3 x 20A branch circuits to serve the 10 cubicles (typical distribution: 3–4 cubicles per 20A circuit) or as required by load calculation and owner preference.

• All branch circuits to be AFCI/GFCI protected if required by code; comply with manufacturer and local requirements.

• Separate circuits for dedicated equipment (printers, monitors, servers) as required.

Materials & equipment (minimum)

• Four (4) commercial-grade power poles with internal raceway and mounting hardware.

• New 120 V subpanel (size and number of spaces per approved single-line).

• Feeder breaker, branch circuit breakers as required.

• Copper conductors (THHN/THWN or code-specified), conduit (EMT/rigid/PVC as required), fittings and boxes.

• Duplex receptacles (commercial grade tamper-resistant), faceplates, isolated-ground devices if required.

• Grounding electrode conductor and materials for bonding.

• Panel labeling, directory cards, wire markers.

• Fasteners, supports, fire-stopping materials for penetrations and floor/ceiling patching and/or trim.

Permits, inspections & code compliance

• Contractor to obtain all permits, arrange and pay for inspections, and ensure all work obtains final approval from Authority Having Jurisdiction (AHJ).

• Comply with NEC, local amendments, and building code requirements. Provide code-compliant AFCI and GFCI protection where required.

• Provide seismic bracing/anchorage if required by local code for poles and panel.

Testing & commissioning •Verify continuity, polarity, insulation resistance, and ground integrity of feeders and branch circuits.

•Test and document correct operation of GFCI/AFCI where present.

• Verify voltage and load balancing at subpanel under measured load.

•Provide written test reports and as-built single-line diagram.

• Correct any punch-list items prior to final acceptance.

Deliverables / closeout

• As-built drawings showing final pole locations, conduit paths, feeder routing, and panel schedules.

• Single-line electrical diagram showing feeder sizing and circuit layout.

• Permit paperwork and inspection sign-offs.

• Equipment warranties and product data sheets.

• Test reports and commissioning checklist.

• Operation & maintenance (O&M) manuals for installed equipment.

Schedule

• Contractor to provide a project schedule including permit lead time, procurement, site mobilization, installation, testing, and inspection.

Safety & site coordination

• Contractor to follow site safety rules and maintain clean, tarp-protected work areas.

Provide temporary protection to finishes and restore any disturbed finishes (patching paint or trim) as excluded or specified.
