C. Source Material Takeoff

• Primary source: the current electrical plans, reflected ceiling plans, legends, symbols, one-line diagrams, panel schedules, lighting schedules, details, notes, specifications, and approved fixture information available for the project at the time this chapter begins.
• Supporting source: the Chapter 1 navigation package, the Chapter 4 room-by-room layout summary, and the Chapter 9 and Chapter 10 finish and cabinet materials for the same project.
• Reference tools: one straightedge and a consistent set of markup colors for tracing control lines.
• Recording medium: one document-control log or spreadsheet capable of holding all five deliverable components listed in Section B.

D. Acceptance Standards

Check	Standard
Device register completeness	Every receptacle, switch, dimmer, sensor, control, and junction box shown on the current electrical plans appears in the register with a confirmed symbol meaning
Fixture register accuracy	Every lighting fixture, fan, and related equipment tag matches a lighting schedule entry, or the mismatch is logged as an RFI-style question
Control map traceability	Every switch leg and control-zone relationship shown on the plans is recorded from switch to fixture or zone, with any unresolved relationship logged
Panel schedule fidelity	Circuit numbers, descriptions, ratings, and dedicated-equipment notes are recorded exactly as documented, with no design alteration
Cross-trade comparison	Device and fixture locations are compared against cabinets, counters, mirrors, plumbing fixtures, wet areas, appliances, ceiling framing, ducts, registers, sprinklers, and structure from earlier chapters
RFI capture	Every missing device, duplicate tag, unclear switching relationship, schedule conflict, inaccessible panel, or uncoordinated connection is recorded, not silently resolved

E. Preparation — Confirm Documents and Systems Included

1. Confirm current electrical plans, reflected ceiling plans, legends, symbols, one-line diagrams, panel schedules, lighting schedules, details, notes, specifications, and approved fixture information. Verify each sheet's revision against the Chapter 1 navigation package before proceeding.
2. Identify normal power, lighting, low voltage, communications, security, fire alarm, generator, photovoltaic, energy-control, and specialty systems included or excluded. Record the systems present for this project on the document-control log and note any system stated as excluded or by others.
3. Locate service equipment, meters, main disconnects, panels, subpanels, transfer equipment, generators, batteries, and major electrical equipment shown. Mark each item's sheet and grid or room location.
4. Match equipment tags to one-line diagrams, schedules, notes, and specifications. Confirm every major equipment tag has a corresponding schedule or specification entry.

F. Device Register Construction

1. Locate receptacles, switches, dimmers, occupancy sensors, controls, junction boxes, floor boxes, appliance outlets, and exterior devices. Add one row per device to the device register with tag, room, and plan location.
2. Identify symbol variants for standard, dedicated, switched, protected, weather-resistant, floor, ceiling, counter, and specialty devices. Record the variant directly from the plan symbol.
3. Do not assign a universal meaning to a symbol without the project legend. Confirm each symbol variant against the current legend before finalizing the device register entry; log any undefined symbol as an RFI-style question.

G. Fixture Register Construction

1. Locate lighting fixtures, ceiling fans, exhaust fans, undercabinet lighting, exterior lighting, emergency lighting, and specialty fixtures. Add one row per fixture to the fixture register with tag, room, and plan or RCP location.
2. Match fixture tags to lighting schedules, reflected ceiling plans, specifications, and approved submittals. Confirm each tag has a corresponding schedule entry; log unmatched tags as RFI-style questions.
3. Identify mounting type, lamp or source, driver, trim, finish, control, and support references where documented. Record only the information the documents actually state.

H. Control Mapping

1. Trace switch relationships and control lines from switches to fixtures or control zones. Record each traced relationship in the control map.
2. Distinguish graphical control intent from exact cable routing. Note in the control map that traced lines represent control intent only, not confirmed field routing.
3. Identify three-way, four-way, multi-location, dimming, sensor, time-clock, and smart-control relationships shown. Record the control type for each traced relationship.

I. Panel and Circuit Reference

1. Locate panel and circuit designations associated with devices and equipment. Record the panel and circuit reference for each device or equipment item where shown.
2. Read panel schedules for circuit number, description, rating, phase, load, spare, and space information as documented. Transcribe this information into the panel and circuit reference summary exactly as issued.
3. Do not change breaker, conductor, circuit, or load design based on plan-reading interpretation. Record any apparent inconsistency as an RFI-style question rather than adjusting the schedule.
4. Identify dedicated circuits for appliances, HVAC, pumps, water heaters, ranges, dryers, and specialty equipment. Flag each dedicated circuit in the panel and circuit reference summary.

J. Cross-Trade Comparison

1. Compare electrical device locations with cabinets, counters, mirrors, doors, windows, trim, plumbing fixtures, wet areas, and appliances. Use the Chapter 9 and Chapter 10 materials for this comparison and record conflicts.
2. Compare ceiling devices with framing, ducts, registers, sprinklers, beams, soffits, access panels, and finish patterns. Record conflicts using the structural and finish information from earlier chapters.
3. Identify device heights, offsets, alignments, and mounting notes where dimensioned. Record only dimensions the documents actually provide.
4. Distinguish typical mounting heights from specific elevations or accessibility requirements. Flag any device requiring an accessibility-specific mounting height for verification.
5. Locate floor, wall, ceiling, roof, cabinet, and exterior penetrations requiring coordination or protection. Cross-reference against the roof and envelope information from Chapters 14 and 15 where applicable.
6. Identify grounding, bonding, surge, generator, photovoltaic, battery, or specialty notes relevant to the project. Record these notes without adding requirements the documents do not state.
7. Identify required box types, supports, covers, weatherproofing, fire stopping, and access references without selecting unshown products. Record only what the documents specify; log any unspecified requirement as an RFI-style question.

K. Scope, Approvals, and Checklist Closeout

1. Identify owner-furnished fixtures, contractor-furnished fixtures, allowances, alternates, controls, and work by others. Record each item's furnishing and installation responsibility as documented.
2. Identify approved submittals, fixture samples, lighting-control shop drawings, testing, labeling, and inspection requirements. Add each hold point to the checklist.
3. Identify missing devices, duplicate tags, unclear switching, schedule conflicts, inaccessible panels, and uncoordinated equipment connections. Consolidate every discrepancy identified in Sections F through J.
4. Create a device checklist organized by room, device, mounting, control, circuit or panel reference, fixture tag, equipment interface, inspection, and unresolved question. Compile the final checklist from the device register, fixture register, and control map.
5. Attach sheet, reflected ceiling plan, schedule, detail, specification, submittal, and manufacturer references. Confirm every checklist row cites its governing source document.
6. Prepare RFI-style questions for ambiguous switching, missing circuits, device conflicts, fixture discrepancies, or incomplete equipment information. Draft one neutral question per unresolved item, stating the document reference and required clarification without proposing an unauthorized design answer.
7. Review the checklist against architectural, cabinet, plumbing, HVAC, ceiling, and structural documents. Confirm the checklist is internally consistent with every earlier chapter's findings before closing this chapter.
