A bid estimate is only as good as the takeoff behind it. When you are chasing a hard bid, you need every line item accounted for — from Division 03 concrete footings to Division 26 electrical feeders — before the bid deadline. We produce unit-priced estimates organized by CSI MasterFormat division, with quantities you can trace back to the drawings. Whether you are a general contractor building a bid from scratch or a subcontractor pricing a single scope, we work from your bid documents and return a complete estimate in 24–48 hours for most projects. If you need help earlier in the process, our preliminary and conceptual estimating service can set a budget before drawings are complete. For hard bid support, we coordinate directly with your team through bid day support. We also provide material takeoff services and labor cost estimating as standalone scopes when you only need part of the estimate.

- Bluebeam Revu, PlanSwift, RSMeans data
Our construction estimating company works from the plans and specifications you issue, whether they are IFC drawings or a BIM model. We set up each project in Bluebeam Revu and PlanSwift for on-screen takeoff, then price material and labor separately using RSMeans data adjusted by ZIP code. Every bid estimate preparation package includes a detailed scope narrative, marked-up plan sets, a trade breakdown by division, and a list of clarifications to request before bid submission. Where the documents are thin, we flag the item and carry it as an allowance or unit price rather than guessing.
We also support the pricing side of the bid. If you receive multiple quotes, our bid leveling services compare them line by line so you can see what each subcontractor included. For owners and GCs who want a check before submission, a bid estimate review tests quantities, labor productivity assumptions, crew size, equipment cost, overhead and profit, and contingency. We track RFIs and addenda during the bid period so the version you price is the version you submit. With 24–48 hour turnaround on most projects, you can focus on subcontractor coverage and bid strategy while we handle the quantities.
What our bid estimating services cover
We take off and price the full scope shown in your bid documents, from general conditions through closeout. Each line item is tied to a spec section and a drawing reference, so you can see exactly where the quantity came from. We price material and labor separately, apply ZIP-code-adjusted rates, and flag any scope that relies on an allowance or unit price.

How we prepare your construction bid estimate
- Document review and setupWe log all bid documents, addenda, and clarifications. We set up a takeoff file in Bluebeam Revu and PlanSwift, overlay the architectural and structural grids, and confirm the drawing scale on each sheet. Any missing sheets or illegible details are flagged immediately so you can request them before the deadline. We also check that the addenda are incorporated and note any discrepancies between the drawings and specifications.
- Quantity takeoff by divisionWe take off quantities in CSI order, starting with Division 01 general requirements and moving through Divisions 02–33. For each line item we record the drawing sheet, grid line, and dimension used. Concrete is measured by volume, steel by weight, and finishes by area — each with the correct unit of measure. We apply waste factors as separate line items, typically 5–10% for concrete and 10–15% for gypsum board, so you can see the allowance.
- Scope gap reviewWe compare the drawings against the specifications to catch items that are specified but not shown, or shown but not specified. Common gaps include fire-rated assemblies, seismic bracing for MEP, and temporary facilities. We list every gap with a recommended allowance or clarification request. For example, if the specs require firestopping but the drawings do not show penetration details, we add a line item and note the UL system to be confirmed.
- Pricing and adjustmentsWe apply ZIP-code-adjusted material and labor rates from RSMeans data, then add sales tax by material category. For items not covered by RSMeans, we use recent quote data or your own historical costs. Escalation is applied based on the bid date and known market trends in your region. We also adjust labor rates for prevailing wage or union requirements if they apply to your project location.
- Quality check and deliveryA second estimator reviews the takeoff for math errors, unit consistency, and missed scope. We cross-check totals against similar projects and flag any outliers. The final estimate is delivered in Excel and PDF, organized by CSI division, with marked-up plan sets and a scope narrative. The marked-up plans show the dimensions and counts used for each line item, so you can trace any quantity back to the drawings.
- Bid day support and clarificationsWe remain available through bid day to answer questions, adjust quantities if addenda are issued, and provide backup detail for your bid form. If you need to level subcontractor quotes, we can assist with that as a separate service. Our goal is to ensure your submitted bid is complete and defensible. We can also provide a bid form summary with alternates and unit prices, ready for submission.
What we need from you
- Bid documentsArchitectural, structural, civil, and MEP drawings, plus specifications and addenda. Incomplete sets lead to assumptions that may not match the final bid.
- Bid date and timeWe schedule our work backward from your submission deadline. Rush turnaround is available for a premium.
- Scope of workWhich divisions you are bidding, and whether you are the GC or a subcontractor. This determines what we include and exclude.
- Project locationZIP code for material and labor pricing, plus any local wage requirements such as prevailing wage or union agreements.
- Site conditionsGeotechnical report, existing conditions survey, and any known utility or environmental issues that affect cost.
- Bonding and insuranceYour bond rate and insurance requirements so we can include these costs accurately in the general conditions.

Units of measure in a bid takeoff
We measure each scope in the unit that matches how it is bought, installed, and priced. The table below shows the units you will see in our estimates and how we derive them.
| Item | Unit | How it's measured |
|---|---|---|
| Concrete footings and slabs | CY | Volume from plan dimensions, converted from cubic feet to cubic yards |
| Structural steel | TON | Weight from member sizes and lengths, using AISC manual weights |
| Roofing membrane | SQ | Area in square feet divided by 100, with laps and waste added |
| Ductwork | LB | Weight from gauge, size, and length per SMACNA standards |
| Plumbing pipe | LF | Centerline length from riser diagrams and floor plans |
| Electrical conduit | LF | Route length from panel schedules and device locations |
| Doors and frames | EA | Count from door schedules and hardware sets |
| Gypsum board partitions | SF | Wall area from room dimensions, both sides where applicable |
Worked example: Division 09 gypsum board takeoff for a small office fit-out
This example walks through a gypsum board takeoff for a 2,400 SF office tenant improvement. All dimensions are illustrative and for demonstration only.
Step 1 — Establish wall lengths and heights. From the architectural floor plan, measure interior partition lengths on each wall type. Assume:
- Type A: 1-hour rated corridor wall, 180 LF, 10 ft high
- Type B: non-rated office partition, 320 LF, 10 ft high
Step 2 — Calculate wall area per side.
- Type A: 180 LF × 10 ft = 1,800 SF per side. Two sides = 3,600 SF.
- Type B: 320 LF × 10 ft = 3,200 SF per side. Two sides = 6,400 SF. Total wall area = 10,000 SF.
Step 3 — Deduct openings.
- Doors: 8 doors at 3 ft × 7 ft = 21 SF each. Total = 168 SF.
- Windows: 4 windows at 6 ft × 5 ft = 30 SF each. Total = 120 SF.
- Total deductions = 288 SF. Net wall area = 10,000 − 288 = 9,712 SF.
Step 4 — Add waste factor. Typical waste for gypsum board is 10–15%. Use 12%. Waste = 9,712 SF × 0.12 = 1,165 SF. Total board to purchase = 9,712 + 1,165 = 10,877 SF.
Step 5 — Break down by board type.
- Type A (1-hour rated): Use 5/8" Type X. Area = 3,600 SF − (doors/windows in Type A). Assume 4 doors and 2 windows in Type A: deductions = (4×21) + (2×30) = 84 + 60 = 144 SF. Net Type A = 3,600 − 144 = 3,456 SF. Add 12% waste = 3,456 × 1.12 = 3,871 SF.
- Type B (non-rated): Use 1/2" regular. Net Type B = 6,400 − 144 = 6,256 SF. Add 12% waste = 6,256 × 1.12 = 7,007 SF.
Step 6 — Accessories and finishes.
- Joint compound: estimate 1 gallon per 300 SF of board. Total board = 10,877 SF → 36 gallons.
- Tape: 1 roll per 500 SF → 22 rolls.
- Screws: 1 box per 1,000 SF → 11 boxes.
- Corner bead: measure outside corners. Assume 40 LF. Add 10% waste = 44 LF.
- Level of finish: Level 4 for painted areas, Level 5 for critical lighting. Note in scope.
Step 7 — Labor and pricing. Apply ZIP-code-adjusted labor rate. Assume $1.20/SF for hang, finish, and tape. Labor = 10,877 SF × $1.20 = $13,052. Material cost: 5/8" Type X at $0.55/SF, 1/2" at $0.40/SF. Material = (3,871 × $0.55) + (7,007 × $0.40) = $2,129 + $2,803 = $4,932. Add accessories $800. Total = $13,052 + $4,932 + $800 = $18,784.
Step 8 — Scope notes. Include fire-rated assembly UL design number, firestopping at penetrations, and cut-and-patch for MEP rough-in. Exclude painting unless specified.
This level of detail lets you trace every quantity back to the drawings and adjust if addenda change wall types or heights.
What drives the cost of outsourced bid estimating
Relative impact on a typical estimate for this trade, based on estimator judgment. Select a bar for details.
Document completeness
A full set of coordinated drawings and specs reduces the number of assumptions we must make. Missing details force us to carry allowances, which can inflate your bid or leave you exposed if the scope is larger than expected. For example, if the structural drawings lack footing schedules, we must assume a size, which may not match the final design.

Missing details force us to carry allowances, which can inflate your bid or leave you exposed if the scope is larger than expected. For example, if the structural drawings lack footing schedules, we must assume a size, which may not match the final design.
A warehouse with tilt-up walls prices differently from a hospital with seismic bracing and medical gas. Complexity increases takeoff time and the number of line items, which affects both our fee and the construction cost. For instance, a hospital requires detailed takeoff of Division 22 and 23 systems, including medical gas piping and isolation panels.
Material and labor rates vary by ZIP code. Prevailing wage, union agreements, and local availability of trades all change the labor component. We adjust rates to your specific project location. For example, a project in a prevailing wage area may have labor rates 20–30% higher than a non-prevailing wage area.
Steel, lumber, and copper prices fluctuate. We apply escalation based on the bid date and current market indices. If your bid is months out, we can carry an escalation allowance to protect against price increases. We track indices such as the Producer Price Index for steel and the Random Lengths lumber index.
A tight deadline may require a rush fee and additional estimator hours. We prioritize accuracy over speed, but we can meet most deadlines with 24–48 hours notice for standard projects. If you have a deadline within 24 hours, we can often accommodate with a rush fee and a focused scope.
The number of CSI divisions you ask us to price directly affects the estimate cost. A single-division subcontractor bid takes less time than a full general contractor estimate covering Divisions 01–33. We scope the effort to your bid form. For example, a drywall subcontractor bid covering Division 09 only takes about half the time of a full GC estimate.
Each addendum requires us to review changes, adjust quantities, and update pricing. Multiple addenda can increase turnaround time and cost, especially if they affect major scopes like structural or MEP systems. For instance, an addendum that changes the roof system from TPO to modified bitumen requires a full re-takeoff of Division 07.
Some clients need a lump-sum bid form, while others require unit prices for every line item. A detailed unit-price estimate takes longer to produce but gives you more flexibility during bid leveling and change order negotiations. For example, a unit-price estimate for concrete will break out formwork, rebar, and concrete separately.
Scope gaps we catch before they cost you the bid
Missed scope is the most common reason bids fail. We review every set for these gaps and flag them with a recommended action.
- Fire-rated assemblies are often shown on architectural plans but not detailed in the specs. We cross-check UL designs and firestopping requirements, then add them as line items so you are not carrying an unknown.
- Seismic and wind bracing for MEP systems is frequently omitted from mechanical and electrical drawings. We look for seismic notes on structural sheets and add bracing, snubbers, and wire as a separate scope.
- Roof screen walls, equipment curbs, and penetration flashing are typically shown on roof plans but missed in the takeoff. We measure them from the roof plan and add them under Division 07.
- Temporary power, lighting, and heat are often buried in Division 01. We read the general requirements carefully and include them as separate line items, especially for winter construction.
- Testing and inspection requirements appear in the specs but not on the drawings. We list special inspections, concrete cylinder tests, weld tests, and duct leakage tests, and price them as a lump sum.
- Cut and patch for MEP rough-in is usually a Division 09 scope but is sometimes left out. We include patching, firestopping at penetrations, and painting of patched areas.
- Utility coordination and tap fees are often owner-furnished, but the contractor may still be responsible for coordination. We clarify the responsibility and add an allowance if needed.
- Landscaping and irrigation are sometimes shown on civil drawings but not included in the bid form. We measure planting beds, sod, and irrigation zones and add them under Division 32 if they are in your scope.
- Signage and wayfinding are often specified in Division 10 but missed in the takeoff. We count room signs, directional signs, and ADA-compliant signage from the signage schedule and add them as a line item.
Material comparisons that affect bid pricing services
Your bid changes with material selection. The table below shows how we compare common options on an installed cost basis per unit.
| Material / System | Unit | Installed cost driver | Takeoff impact |
|---|---|---|---|
| Structural steel vs. cast-in-place concrete frame | TON vs. CY | Steel: mill price, fabrication, erection, fireproofing. Concrete: formwork, rebar, pumping, finishing. | Steel measured by weight from member sizes; concrete by volume from dimensions. |
| Brick veneer vs. EIFS vs. metal panel | SF | Brick: masonry labor, ties, flashing. EIFS: substrate, mesh, finish. Metal panel: framing, panel gauge, sealants. | Brick requires brick count and mortar; EIFS requires substrate board; metal panel requires panel layout. |
| TPO vs. EPDM vs. modified bitumen roofing | SQ (100 SF) | TPO: membrane, heat-welded seams, insulation. EPDM: adhesive, seams, insulation. Mod-bit: torch or cold-applied, multiple plies. | TPO/EPDM measured by area with laps; mod-bit measured by area with ply layers. |
| Copper vs. PEX vs. CPVC domestic water piping | LF | Copper: material cost, soldering labor. PEX: material cost, crimp fittings, manifold. CPVC: material cost, solvent welding. | Copper measured by diameter and fitting count; PEX by length and manifold locations. |
| Black steel vs. PVC vs. cast iron sanitary piping | LF | Black steel: threading, hangers, firestop. PVC: solvent weld, expansion joints. Cast iron: heavy, no-hub couplings, firestop. | Black steel requires hanger spacing and firestop; PVC requires expansion fittings; cast iron requires coupling count. |
| Galvanized vs. stainless steel ductwork | LB | Galvanized: standard SMACNA gauges, slip joints. Stainless: higher material cost, welding, special supports. | Galvanized measured by gauge and size; stainless requires weld count and passivation. |
Codes and standards that affect your bid estimate
Model codes
Model codes set minimum requirements that change quantities. The International Building Code (IBC) governs occupancy, fire ratings, and egress, which drive rated wall assemblies, door hardware, and sprinkler coverage. The International Energy Code (IECC) sets insulation R-values and lighting power densities, affecting Division 07 and 26 quantities. The NEC (NFPA 70) dictates conduit fill, wire sizing, and device counts. The IPC or UPC governs plumbing fixture counts and pipe sizing. NFPA 13 determines sprinkler head spacing and pipe sizes. Confirm the adopted editions with your local building department.
Industry standards
Industry standards define how materials are measured and installed. ACI 318 for concrete strength and rebar detailing affects concrete volume and steel weight. ASTM standards for steel (A992), gypsum board (C840), and roofing (D4434) set quality but not quantity. SMACNA duct construction standards determine gauge and reinforcement, which changes duct weight. GA-216 for gypsum board application affects waste and finish level. NRCA roofing manuals specify flashing details that add linear feet. These standards are referenced in specs and must be read to price correctly.
Specification sections
CSI MasterFormat sections contain the scope that drives cost. Division 01 general requirements include temporary facilities, testing, and closeout, which are often overlooked. Division 03 30 00 cast-in-place concrete specifies mix designs, curing, and finish, affecting labor. Division 05 12 00 structural steel includes connection details and shop primer. Division 07 21 00 thermal insulation gives R-values and thickness. Division 09 29 00 gypsum board specifies thickness, type, and finish level. Division 22 11 00 plumbing fixtures lists counts and types. Division 26 05 00 electrical includes conduit and wire specs. Read each section for quantity-affecting clauses.
Local amendments
Local jurisdictions adopt model codes with amendments that change cost. For example, some cities require stricter seismic bracing, higher insulation R-values, or additional firestopping. Coastal areas may have wind-borne debris requirements for glazing. States with prevailing wage laws set minimum labor rates. Some municipalities require fire sprinklers in smaller buildings than the model code. Always verify the adopted code edition and local amendments with the local building department before finalizing your bid, as these can add line items or increase quantities.
