What do electrical estimating services include?
Electrical estimating services turn electrical drawings and specifications into counted and measured quantities, then price them into a bid. KNR's takeoff covers switchgear, panelboards, feeders, branch circuits, luminaires and devices, delivered as an Excel workbook, PDF summary and marked-up drawings with the arithmetic and data source shown.
Our Professional Electrical Estimating Services
An electrical estimate lives or dies on the takeoff sheet. We measure each raceway run, conductor set, box, device and piece of gear from the drawings, assign a unit and a measurement rule, and show the arithmetic so your estimator or project manager can reproduce every line. Pricing starts from national average unit costs, adjusted with published U.S. Bureau of Labor Statistics wage and price data, then reviewed by an estimator before it reaches you. The fee is quoted per project after we review the plans, and the deliverable is an Excel workbook and PDF summary with marked-up drawing pages.
We do not name a turnaround, because scope drives the schedule more than page count does. What you can check is the trail: conduit measured in linear feet by trade size and system, wire in feet per gauge and conductor count, gear counted by NEMA type and ampacity, devices counted by type and mounting height. The same discipline carries into the low-voltage side, where our telecom and structured cabling estimates support the Division 27 and 28 scope alongside the power takeoff.
Electrical material takeoffs
We measure EMT, rigid conduit and other raceway in linear feet by trade size, separated by system so feeder and branch quantities never blend. Conductors are taken off in feet per wire gauge, with the home run lengths and the service entrance included. Transformers, switchgear and panelboards are counted by rating and enclosure type, with the feeder schedule cross-checked against the single-line diagram. You get a line-item quantity sheet tied to drawing sheets and detail numbers, and our electrical takeoff services keep the luminaire schedule, device count and junction box quantities on the same sheet as the raceway.
Electrical labor cost estimates
Our electrical labor estimating services convert quantities into hours using labor units per item, then apply the wage data for the trade and the prevailing conditions in your market. Wire pulling, terminations and gear setting are priced as separate line items rather than buried in a single lump. A crew mix assumption is stated on the sheet so you can test it against your own supervision plan. See how this interfaces with the wider scope in our mep estimating services.
Bid-ready electrical cost estimates
The bid package pulls the takeoff and the labor build into one structure: material, labor, equipment, subcontractor allowances and indirect costs, each on its own line. Alternates and unit prices are listed separately so you can carry them into the bid form without recalculating. Every extension is shown, and any assumption we had to make is flagged as a request for information item. Send your plans and we will quote the fee after reviewing the drawing set.
What Is Included in Our Electrical Estimates?
Our electrical estimating services cover CSI Division 26 work and the adjacent low-voltage scopes that share the same drawings. Each item on the sheet carries a unit, a measurement rule and a source sheet reference, so a reviewer can trace a number back to the drawing it came from. Where the documents are silent on a detail, we list it as an assumption instead of filling the gap silently. Scopes that cross into mechanical equipment connections are priced alongside our hvac estimating services so the disconnect, control wiring and feeder appear once, not twice.
Raceway, wire, gear, luminaires and devices
The measured scope typically includes:
- Raceway: EMT, rigid conduit, IMC, PVC and MC cable, in linear feet by trade size and system.
- Conductors: copper and aluminum wire in feet per gauge, with conductor count and insulation type from the feeder schedule.
- Gear: switchgear, switchboards, panelboards, transformers and disconnects, counted by rating and NEMA enclosure type.
- Lighting: luminaires and lamps from the lighting fixture schedule, with mounting type and control devices.
- Devices and boxes: receptacles, switches, junction boxes and floor boxes, counted by type and mounting height.
- Systems: fire alarm, data and low-voltage rough-in measured from Division 27 and Division 28 drawings where issued.
Linear feet, counts, hours and device tallies
Quantities come out in the units an estimator can price: linear feet of raceway by size, feet of conductor by gauge, each count for gear and luminaires, and a device count by type. Junction box quantities follow the box-fill and pull-point rules you specify, and conduit fill is checked against the wire complement on the feeder schedule. Where voltage drop drives a larger wire size than the schedule shows, we note the conflict rather than pricing the smaller conductor. Branch circuit estimating is done circuit by circuit so the home run lengths are visible, and the same discipline carries into our electrical takeoff services for the remaining divisions.
Materials, labor, equipment and cost breakdowns
The workbook separates the cost structure so each part can be challenged:
- Material: extended quantities at unit prices, with copper wire and cable and steel mill products adjusted using the published producer price index movement.
- Labor: hours per line item at stated labor units, multiplied by the wage rate for the trade and adjusted for the project's market.
- Equipment: lifts, benders, pulling equipment and temporary power, listed as separate items.
- Indirect: supervision, permits, submittals and contingency, shown as their own lines.
- Markups: overhead and profit applied at the level you specify, not assumed.
Who Needs Our Electrical Estimating Services?
Electrical construction estimating is a document-reading exercise before it is a pricing exercise. The groups below use the same takeoff for different decisions, so the sheet is organized to answer both quantity questions and price questions without a rebuild. Each group receives the same traceable output from our electrical estimating services: unit, measurement rule, arithmetic and data source on every line.
Electrical subcontractors
An electrical contractor bidding several jobs a month needs quantities fast and a labor build that matches their own crews. We take off the wire pulling, terminations, gear setting and device installation, then state the labor units so your estimator can swap in your historical productivity. The bid estimate comes back structured for the bid form, with alternates carried separately. Contractors who price labor in-house often pair this with our labor cost estimating services to reconcile crew rates against the takeoff hours.
General contractors and home builders
A general contractor needs the electrical package to sit inside the master budget without surprises. We measure Division 26 scope from the luminaire schedule and panel schedules and flag gaps between the drawings and the specification, so the electrical number you carry is complete. That matters most on design-build work, where the electrical scope is priced before the drawings are final. Our electrical estimating services feed the same workbook used for the other trades, so the package totals roll up without a second pass.
Developers, architects and suppliers
Developers use the estimate for pro forma and change-order review, and architects use it to test whether the design fits the budget. Suppliers and manufacturers can use the luminaire and gear counts to check their own quotations against the drawings. For the full building picture, our construction cost estimating services put the electrical package alongside the other divisions.
Types of Electrical Projects We Estimate
The measurement rules change with the building type, and so does the labor. The three groups below cover most of the work we see; each one has a different failure mode when the takeoff is done carelessly.
Residential projects
Residential work turns on device count and home run length. We count receptacles, switches, smoke and carbon monoxide alarms, and lighting outlets room by room, then measure the branch circuit home runs back to the panel. Service size, panel schedule and any generator or transfer switch provisions are taken off separately. Multi-family work adds a per-unit count so the estimate can be checked against a unit mix.
Commercial buildings
Commercial scope is driven by the panel schedules, the single-line diagram and the reflected ceiling plan. We measure feeder and branch raceway, count panelboards and transformers, and take off luminaires from the lighting fixture schedule with controls. Tenant fit-out work is separated from base building so a landlord and tenant split can be priced. Our quantity takeoff services cover the drawing measurement behind this scope.
Industrial and infrastructure projects
Industrial work adds rigid conduit and cable tray runs, motor connections, controls and grounding, and the labor units rise with elevation and access difficulty. Infrastructure scope such as site lighting, traffic signal and duct bank work is measured by run length and structure count. The electrical bid estimate here also carries arc flash labeling, coordination study allowances and testing as separate items. Compare the adjacent trades in our mechanical estimates where the scope overlaps.
Our Electrical Estimating Process
An electrical estimate is only as good as the drawing set it starts from. We work from the construction documents you send: single-line diagrams, panel and feeder schedules, luminaire schedules, floor plans with device layouts, and the Division 26, 27 and 28 specifications that govern them. Send the full package to get a quote and we log the sheet list, revision dates and addenda before any quantity is counted. Missing sheets become written RFIs, not assumptions buried in a total.
Submit drawings and specifications
You send the PDF set, the specification book, and any addenda issued to date. We confirm the drawing index against what arrived and flag gaps in writing: a missing panel schedule, a lighting plan without fixture types, or a Division 28 scope with no device schedule. That first check prevents the most common cause of a low electrical bid estimate — pricing a set that was never complete.
Plan review and digital takeoff
We review the single-line diagram for service size, transformer ratings and distribution, then complete the switchgear and panelboard takeoff by reading each schedule line by line: frame size, trip rating, bus, enclosures and lugs. From there we trace feeders, count luminaires against the fixture schedule, and run the device count — receptacles, switches, data and fire alarm devices — by room and circuit. Each branch circuit is measured for conduit, wire and boxes, with circuit numbers carried into the takeoff so a reviewer can trace any quantity back to a sheet. Where feeders cross into mechanical equipment rooms, our piping estimates cover the routing that the electrical scope hands off.
Cost calculation, quality checks and delivery
Quantities are priced with labor units by item and material costs from current pricing data, then a second estimator checks the extension arithmetic, unit conversions and scope coverage against the specification sections. The finished workbook includes a PDF summary and marked-up drawing pages showing what was counted. Any open RFI or excluded scope is listed on the summary so you know what the number does and does not cover before it goes into your bid.
Sample Electrical Estimate and Deliverables
The example below is illustrative and shows how an electrical quantity takeoff is structured, not a price for any real project. Assume a two-story tenant fit-out of 12,000 sq ft with 180 recessed LED troffers, 96 duplex receptacles, 40 switches, and 22 home runs of 3/4-inch EMT averaging 85 ft each. Labor units are illustrative hours per unit multiplied by a loaded crew rate; your project will differ with wage area, union status and site conditions.
| Item | Qty | Unit | Unit cost range | Extended range |
|---|---|---|---|---|
| 3/4" EMT with fittings (branch) | 1,870 | LF | $2.10 – $2.60 | $3,927 – $4,862 |
| THHN copper conductors, 12 AWG | 5,610 | LF | $0.28 – $0.36 | $1,570.80 – $2,019.60 |
| Recessed LED troffer, type A | 180 | EA | $95 – $135 | $17,100 – $24,300 |
| Duplex receptacle with plate | 96 | EA | $14 – $22 | $1,344 – $2,112 |
| Switch, 20A | 40 | EA | $12 – $18 | $480 – $720 |
| 4" square junction box | 58 | EA | $6 – $10 | $348 – $580 |
| Labor, electrician (illustrative) | 612 | HR | $72 – $88 | $44,064 – $53,856 |
| Total (illustrative) | — | — | — | $68,833.80 – $88,449.60 |
Excel quantity takeoff sheet
Every line carries an item number, CSI MasterFormat code, description, quantity, unit, measurement rule and drawing reference. Lighting fixture takeoff services produce counts tied to the luminaire schedule type marks (A, B, C), so a substitution on type B can be priced without re-counting the plan. Feeder and branch lengths are taken from scaled plans with a stated vertical allowance, and junction box counts follow the home run routing rather than a square-foot allowance.
Marked-up drawings
We return the drawing pages with color-coded counts, highlighted runs and circuit tags for each feeder schedule and panel. The markup lets your foreman check a quantity in seconds and lets a reviewer see exactly which sheet a number came from. Where the design leaves conduit routing undefined, the markup shows the assumed path and the RFI that should confirm it.
Itemized cost estimate
The cost sheet separates material, labor hours and the extended total, and references the code basis — NEC edition as adopted by the local authority, which you should confirm with the building department. Devices, boxes and fittings are priced as separate lines so you can adjust for a different specification without rebuilding the estimate. The table below is illustrative only.
Software and Pricing Data We Use
The chart below tracks the Producer Price Index series for the materials that dominate an electrical package — copper wire and cable, steel products and plastic construction products — rebased to 100 at the start of the period. It shows direction and relative movement, not a unit price. Copper wire and cable moves fastest and feeds directly into every feeder and branch circuit estimating line, which is why we re-price conductor quantities at the date of your bid rather than at the date of the original takeoff.
Takeoff and estimating software
We work in three tool categories: on-screen PDF takeoff for measuring conduit and cable runs at scale, spreadsheet-based estimating for building the line-item structure, and subscription cost databases for material and labor unit pricing. The panel schedule drives the takeoff structure, so each panel becomes its own worksheet section. Checks on conduit fill and voltage drop are performed against the NEC tables before a run length is accepted.
Regional material and labor pricing method
Material and labor are priced from national average unit costs, then adjusted for the project's location, prevailing wage requirements and conditions such as occupied space or shift work. The wage table below shows BLS median hourly wages for the trades that shape an electrical crew's loaded rate. The estimator reviews every adjustment before the estimate is released, and the assumptions are printed on the summary.
Material price movement, Oct 2023 to Sep 2026
| Occupation | 25th percentile | Median | 75th percentile |
|---|---|---|---|
| Electricians | $23.76 | $30.38 | $40.36 |
| Construction laborers | $18.57 | $22.66 | $28.72 |
| First-line supervisors, construction trades | $30.48 | $38.42 | $48.78 |

Why Contractors Choose Our Estimating Services
Every number on our sheet answers three questions: what was measured, by what rule, and from what source. That standard is what separates a defensible electrical bid estimate from a lump sum someone has to trust. It also makes the estimate usable after award, when the project manager needs the same quantities for a subcontract and a schedule of values. Teams that send us Division 26 scope often send the rest of the MEP package at the same time, and our professional plumbing estimating services follow the same measurement rules.
Trade-specific expertise
Our estimators read a single-line diagram for service and distribution logic before they count a single device. They know that a feeder's wire gauge follows from the overcurrent device and the run length, not from habit, and that labor units change with ceiling height, cable type and whether the work is in a finished space. That judgment is applied line by line across the electrical quantity takeoff, including low voltage and fire alarm scope.
Quality control and clear assumptions
A second estimator checks each workbook for extension errors, unit mismatches and scope gaps against the specification. Assumptions — vertical drops, spare capacity, excluded temporary power — are written on the summary rather than absorbed into the total. When a drawing is ambiguous, we issue an RFI instead of choosing silently.
Turnaround, communication and revisions
Delivery dates are agreed in writing when the scope and drawing set are confirmed, and we tell you at that point what could move the date, such as incomplete schedules or addenda issued mid-takeoff. Revisions are handled as a documented change to the workbook, with the affected lines identified so you can see the cost impact of each addendum. Questions go to the estimator who built the sheet.
Electrical Estimating Services Pricing
The fee for our electrical estimating services is quoted per project after an estimator reads the drawings, so no rate card is published. Before quoting, we count the sheets by CSI Division 26, 27 and 28 scope, list the alternates and addenda that change quantities, and note whether the package includes gear, branch, lighting and devices or only part of it. A single-division lighting and device package prices differently from a full feeder-and-switchgear package with a single-line diagram and panel schedules.
The calculator below converts a base electrician wage into a loaded labor rate. Enter the base wage, the burden percentage, the share of hours worked at overtime, the crew size and the hours; it returns the loaded rate, the blended rate with overtime, labor hours and crew labor cost. Use it to test the labor side of the bid before you compare it with our line-item takeoff.
The chart below shows how the copper wire and cable index has moved, which matters on any package with long feeder runs. A device and receptacle count takeoff is quick to price because the count is finite; a switchgear package is not, because NEMA ratings, bus configurations and delivery lead times change the material value on every quote.
How quotes are calculated
We price quantities first, then apply labor units by item, then adjust the material and labor with published U.S. wage and price data and an estimator's review. The deliverable is an Excel workbook with the arithmetic visible on each line, plus a PDF summary and marked-up drawing pages showing what was counted. If a drawing is ambiguous, we raise an RFI rather than guessing a quantity into the total. Send your plans to get a quote once the sheet list is complete.
What affects price and delivery time
Scope breadth is the first driver: a lighting-only package takes less review than a full Division 26 set with transformers, switchboards and feeders. Drawing quality is the second: a coordinated set with a luminaire schedule and panel schedules takes fewer RFIs than a design-development set. Alternates, addenda, prevailing wage requirements and the number of buildings also move the fee. We quote the fee after plan review and do not promise a delivery time until the scope is confirmed.

Electrical Estimating Services Across the US
Electrical pricing moves by region for reasons that show up on the takeoff sheet. Wage levels differ by metro, and public work often carries prevailing wage requirements that change the labor half of the estimate. Material delivery matters too: a panelboard or switchgear package shipped to a remote site costs more than one delivered to a metro warehouse, and freight is a line item, not a rounding error. Climate and code editions differ as well, so we confirm the adopted NEC edition and any local amendments with the building department before pricing.
Our electrical estimating services run from one team for all U.S. states, so the method is the same everywhere and only the inputs change. We adjust labor with published wage data by trade and adjust material with published price indexes, then review the result. The same rules apply to MC cable branch work and to feeder schedules, and every item we price is expected to carry a UL listing or an equivalent mark before it goes in the bid.
Frequently Asked Questions
How much does an electrical estimate cost?
The fee is quoted per project after we review the drawings, so it depends on sheet count, the number of panels and feeders, fixture and device counts, and whether you need a full bid package or a takeoff only. Send the plan set and specifications and the quote states the scope, the deliverable format and the fee before any work starts.
How long does an electrical takeoff take?
The delivery date is set by the size of the drawing set, how many sheets need counting, and how quickly open questions are answered. We confirm the date in the quote, and it moves only if revisions or missing panel schedules arrive after the count begins. Nothing is promised before the plans are reviewed.
Do you estimate labor and material costs?
Yes. Material quantities come from the takeoff, and labor is priced from labor units applied per item, then adjusted with published U.S. wage data and reviewed by an estimator. The workbook shows the unit, the quantity, the labor unit and the arithmetic so you can audit any line back to the drawing sheet it came from.
What drawings do you need?
Send the electrical plan sheets, the single-line diagram, panel and feeder schedules, the luminaire schedule and the specifications, plus any addenda. Architectural and structural sheets help locate devices and sleeves. If the panel schedules are missing, we list the gap as an RFI rather than guessing breaker sizes or spare capacity.
Can you use my estimate template?
Send your template with the plans and we confirm whether the estimate can be delivered in it. If the template's structure does not carry the labor units and measurement rules we apply, we say so before starting and propose the closest format we can support, usually our Excel workbook with your columns mapped in.
Do you sign NDAs?
Clients can request an NDA before sending drawings, and the terms are agreed before plan review begins. Tell us at first contact so the agreement is signed before any files are transferred, and send only the sheets needed for the scope you want priced.
What is included in your electrical estimating services?
Our electrical estimating services cover a full quantity takeoff by CSI Division 26, 27 and 28 scope: feeders, branch circuits, conduit and wire, boxes, devices, luminaires, switchgear, panelboards and low-voltage systems, priced to a bid-ready total. Each line carries a unit, a measurement rule and the source sheet, and the package includes an Excel workbook, a PDF summary and marked-up drawings.
How do you count devices and receptacles?
Devices are counted from the floor plans by type and mounting height, then checked against the panel schedule so circuit counts match. Each receptacle, switch, data outlet and junction box gets its own line with a unit count, and boxes are added at every home run and pull point rather than assumed inside the wire quantity.
Do you price conduit and wire by the foot or by the run?
Both. Raceway is measured along the routed path in linear feet by trade size and material, and wire is pulled by circuit from the panel to the last outlet, with conductor count taken from the feeder schedule. Conduit fill and wire gauge are checked against NEC tables, and any run that needs a pull point is flagged.
How do you handle lighting fixture takeoffs?
Fixtures are counted by type from the luminaire schedule, with the type mark, lamp and ballast or driver, mounting and voltage carried onto each line. Fixtures shown on the plan but missing from the schedule are raised as an RFI, and lighting control devices are counted separately so the control scope is not buried in the fixture price.
Can you break the estimate out by phase or by building?
Yes. The workbook can be sorted by building, floor, panel or construction phase, as long as the drawings show those boundaries. Tell us the breakdown you bid with and we structure the takeoff sheet so the subtotals fall out of the count instead of being allocated afterward.
How do you handle copper and steel price movement?
Copper wire and steel conduit are priced at the index level in effect when the estimate is prepared, and the basis date is printed in the workbook. The public producer price data we track shows both moving sharply over the past year, so bids that hold for months should carry an escalation note or a re-pricing date.
Do you estimate fire alarm and low-voltage scope?
Yes. Division 28 fire alarm devices, notification appliances and panels, and Division 27 data, telecom and security rough-in are counted from their own drawings and schedules. Where the low-voltage scope is design-build with no device layout, we price the pathways and boxes shown and list the missing device counts as an assumption.
