Edge Estimates prepares trade-specific quantity takeoffs and cost estimates for specialty subcontractors across all 50 states. You send drawings, we return a line-item estimate in CSI MasterFormat — or your own cost codes — with marked-up plans in 24 to 72 hours. Fixed fee, quoted within two hours, no retainer.
Subcontractor estimating services are outsourced cost analysis services that measure material quantities, calculate labor hours, and price a single trade scope so a specialty contractor can submit a competitive bid 2026 estimating cost benchmark. Unlike a general contractor’s estimate, which spans an entire building, a subcontractor estimate covers one trade package — electrical, mechanical, concrete, drywall, roofing — in the depth that trade requires, and flags any scope that falls between the packages a general contractor has divided the job into.
That last point is the part most estimating providers skip. When a general contractor splits a project into bid packages, the seams between those packages are where money leaks. Fire-caulking that could sit with the drywall sub or the mechanical sub. Housekeeping pads that may belong to concrete or to the equipment installer. Temporary power that either the electrician carries or nobody does. A takeoff that measures your quantities correctly but says nothing about those seams still leaves you exposed.
Every estimate Edge Estimates prepares for a subcontractor includes a written scope section that lists what is included, what is excluded, and what we assumed. You can lift that section straight into your scope letter.
Subcontractors choose Edge Estimates because the work is priced per project instead of by retainer, delivered in 24 to 72 hours, and formatted in the cost-code structure the sub already uses. Estimates are prepared by trade-specific estimators using Bluebeam Revu, PlanSwift, FastPIPE, and RSMeans pricing adjusted to the project zip code.
Edge Estimates has operated since 2016 out of Los Angeles, with a regional office in Dallas. The team is built around trade specialists rather than generalists — the estimator who prices your process piping is not the same person who prices your flooring, because those two takeoffs demand different reference knowledge and different software. Meet our estimating team.
Electrical goes to an electrical estimator who reads panel schedules and one-line diagrams. Piping goes to someone who works from P&IDs and isometrics. Trade fluency is what keeps a bid credible.
Pay per estimate. Fixed fee quoted before any work starts. If your bid volume is seasonal, your estimating spend moves with it instead of sitting as fixed overhead.
Standard delivery is CSI MasterFormat. If your accounting system runs on internal cost codes or UniFormat, we build the estimate in that structure so it imports without rework.
RSMeans location factors applied at the project zip code, plus a proprietary cost database built from vendor quotes. Send us your own labor rates and we use those instead.
Fixed-fee quote inside two hours of receiving drawings. Single-trade takeoffs typically land in 24 hours. Multi-trade packages in 48 to 72.
Drawings are used only to prepare your estimate and are never shared. We will execute an NDA before you send anything if your project requires it.
Most subcontractors come to us for one of five things. You can request any of them individually — there is no bundled package you have to buy into.
A measured count of everything your scope installs, organized by system and specification. Linear feet of conduit by size and type. Tons of structural steel by member. Square feet of drywall by assembly and finish level. Cubic yards of concrete by mix design. Each line carries its unit of measure, a waste factor where appropriate, and a reference back to the drawing sheet it came from, so you can check any number in about ten seconds.
The takeoff with material pricing, labor hours, and equipment allowances applied. Labor is calculated at productivity rates appropriate to the trade and the conditions — overhead work, confined space, occupied-building phasing, and night shift all carry different rates, and we adjust rather than applying a flat number. You get material and labor split on every line so you can see where the cost actually sits.
We read the specification sections that apply to your trade, track the addenda, and identify scope that is either assigned ambiguously or missing from the drawings entirely. This is delivered as a written list of clarifications you can send to the general contractor before bid day, or carry as documented exclusions in your proposal.
Once you are on the job, scope changes. We prepare change order pricing from the original takeoff so the delta is defensible — original quantity, revised quantity, the difference, and the cost impact including any productivity loss from resequencing. Having the baseline documented is what turns a change order conversation into a short one.
You built the estimate in-house and want it checked before it goes out. We take your numbers and the drawings and produce an independent takeoff, then reconcile the two line by line and tell you where they diverge and why. Subcontractors use this on high-value bids where being 15% off in either direction is expensive.

The same trade scope prices differently depending on the building it sits in. A hospital electrical package carries redundancy, isolated grounding, and infection-control phasing that an office fit-out does not. We adjust the productivity assumptions accordingly.
New build, core and shell, tenant improvements, and occupied-building renovations with phasing and after-hours work.
Hospitals, surgical centers, and clinics — infection control barriers, medical gas, redundant systems, OSHPD-level documentation.
K–12 and higher education, frequently prevailing wage, summer-window schedules, and public bid form requirements.
Podium and wrap construction, repetitive unit takeoffs by type, custom and production single-family.
Process piping, equipment setting, heavy electrical distribution, fireproofing. See Industrial Estimating.
Rollout programs with repeatable scope, restaurant build-outs, hotel guest room and public area packages.
Tilt-up and pre-engineered structures, dock equipment, high-bay lighting, ESFR sprinkler, large-area slabs.
Municipal, federal, and transit work with Davis-Bacon wage compliance. See Public Projects.
Redundant power and cooling paths, busway, containment, commissioning-heavy scopes with tight tolerances.
Outsourced estimating helps subcontractors whose bid volume exceeds their internal estimating capacity, who are entering an unfamiliar market or building type, who face a deadline inside 72 hours, or whose volume does not yet justify a full-time estimator’s salary and software costs.
We take two while your estimator focuses on the one with the best win probability. You stop declining invitations because of bandwidth.
The owner or PM stops estimating at 10pm. Bids get prepared by someone whose full-time job is estimating.
You get a credible first number in a market where you have no historical cost data to draw on.
Single-trade takeoffs typically deliver in 24 hours. Tell us the deadline and we confirm feasibility before you approve the quote.
A full-time estimator plus takeoff software licenses runs well into six figures annually. Per-project pricing scales down when your pipeline does.
An independent second estimate on a job that could make or break the year is cheap insurance against a costly error.
Coverage without a rushed hire. Bidding continues while you recruit properly.
Honestly — keep this in-house. Your own historical productivity data will beat any outside estimate on work you do every week.
Where we do not add value: if you bid the same scope repeatedly and have clean historical cost data, your internal numbers are better than ours. Outsourcing is a capacity and coverage tool, not a replacement for trade knowledge you already own. Most of our long-term clients use us alongside an in-house estimator, not instead of one.
Every deliverable includes all six items below. Nothing here is an upcharge.
Organized by CSI MasterFormat division or your cost codes, with material, labor hours, labor cost, and equipment separated on each line so you can adjust any assumption yourself.
The PDF drawing set annotated by system so every quantity traces back to a specific location on a specific sheet. This is what makes the estimate auditable rather than a black box.
Inclusions, exclusions, and assumptions in plain language, ready to paste into your proposal or scope letter.
Total man-hours by activity with the productivity basis stated, so you can sanity-check against your own crews before submitting.
Questions worth sending to the general contractor, and any scope gaps between bid packages that we spotted in the documents.
If an addendum lands or the scope shifts after delivery, the first update is included at no charge.
The process runs in four steps. Email your drawings to plans@edgeestimates.us, receive a fixed-fee quote within two hours, approve it, and receive the completed estimate with marked-up plans in 24 to 72 hours. No work begins and no payment is due until you approve the quote.
Email plans to plans@edgeestimates.us. Include the project zip code, your bid deadline, the trades you need, and your labor basis — union, open-shop, or prevailing wage. If your set is incomplete, say so; we work from partial documents regularly and note the assumptions.
An estimator reviews the scope and sends a firm price and delivery date. No hourly billing, no estimate that grows once work is underway. If your deadline is tighter than our standard window we tell you before you commit.
A trade specialist performs the takeoff in Bluebeam Revu, PlanSwift, or trade-specific software, then applies RSMeans pricing at your project zip code — or your own labor rates if you supplied them. Specifications and addenda are read alongside the drawings, not skipped.
The Excel workbook, marked-up plans, and scope notes arrive together. Walk through any line with the estimator who built it. One revision round is included if the scope moves.
A subcontract bid has thinner margin than most people outside the trade assume. Competitive specialty work commonly targets an 18–25% gross margin, and that gets consumed quickly by a single estimating error. Two mistakes account for most of the damage.
Base wage is not labor cost. Add payroll taxes, workers’ compensation, and benefits and the fully burdened rate typically runs 25–40% above the base wage. A bid built on unburdened wages looks competitive and loses money on every hour worked. Every Edge Estimates deliverable states the labor basis explicitly so you can confirm it matches your actual burden before you submit.
The second failure is accepting loose scope boundaries. Work that sits between two bid packages — firestopping, housekeeping pads, temporary services, cutting and patching, final cleaning — gets assumed by nobody at bid time and assigned to somebody after award. That somebody is usually whichever sub has the weakest paper trail. Our written scope section exists specifically to give you that paper trail.
Knowing your real cost before submitting means you can price to win without pricing below cost.
Documented quantities and stated assumptions give you a defensible baseline for every change order that follows.
Capacity is the real constraint on win rate. More bids submitted at the same accuracy means more awards.
Accurate quantities support early procurement and bulk pricing instead of reactive ordering at retail.
Comparing our productivity assumptions against your actuals tells you where your internal rates have drifted.
A clean, itemized proposal with clear exclusions reads as a lower-risk sub. That matters in bid leveling.
No estimate removes construction risk. Site conditions, design changes, material lead times, and labor availability all move final cost. What a detailed estimate does is shrink the range of uncertainty you carry into a bid — and document what you priced, so a dispute later is a short conversation.
Edge Estimates uses Bluebeam Revu for digital plan measurement, PlanSwift and Trimble for structural and civil takeoffs, FastPIPE and FastDUCT for piping and sheet metal, and RSMeans cost data adjusted by project zip code — alongside a proprietary cost database built from current vendor quotes.
Digital measurement and markup on PDF sets. This is what produces the color-coded plans you receive, so quantities stay traceable to the sheet.
DWG and PDF takeoffs for concrete, framing, finishes, and general building scopes with assembly-based quantity generation.
Structural steel detailing quantities, civil earthwork surface comparison, and complex site layout takeoffs.
Piping takeoffs by spec and diameter from P&IDs and isometrics; sheet metal weight by gauge and system for HVAC.
Material, labor, and equipment cost data with location factors applied at the project zip code rather than a national average.
Vendor quotes and trade data collected since 2016, used to sanity-check published pricing against what the market is actually charging.
Every workbook ships with live formulas and no protected cells. Change a labor rate or a waste factor and the estimate recalculates — nothing is hardcoded, and nothing is hidden from you.
Accuracy is a process question, not a talent question. Four controls sit on every estimate before it leaves.
The estimator assigned holds working knowledge of that specific trade. Electrical work is not priced by whoever is available.
Quantities are reconciled against the spec sections and every addendum, not the drawings alone. Drawing-only takeoffs miss material grades, finish levels, and testing requirements that carry real cost.
A second estimator reviews the workbook against the marked-up plans before delivery, checking unit-of-measure consistency, productivity assumptions, and completeness against the scope list.
Anything not determinable from the documents is written down rather than quietly guessed. If the drawings do not show it, the estimate says so.
We also close the loop where clients let us. If you send back actual installed quantities and hours after a job, we compare them against what we estimated and adjust our productivity assumptions for your future work. That feedback is the most valuable calibration data available, and it is why long-term clients get progressively tighter numbers.
Edge Estimates charges $250 to $2,500 per estimate on a fixed-fee basis. Single-trade takeoffs for a small to mid-size project start around $250. Multi-trade packages and large commercial scopes typically run $800 to $2,500. Every project is quoted individually within two hours of receiving drawings, and no payment is due until you approve the quote.

Edge Estimates serves subcontractors in all 50 states from its Los Angeles headquarters and its Dallas regional office. Every estimate is priced using RSMeans location factors at the project zip code, so pricing reflects local labor and material markets rather than national averages.
4319 W Jefferson Blvd, Los Angeles, CA 90016. Covering California, Nevada, Arizona, Oregon, Washington, and the Southwest. California carries some of the highest construction labor rates in the country between prevailing wage requirements and union scale agreements — both are handled as standard.
18625 Midway Rd, Dallas, TX 75287. Covering Texas, Oklahoma, Louisiana, Arkansas, and the Gulf Coast — including one of the highest-volume open-shop commercial markets in the United States.
To receive a fixed-fee quote, email your drawings to plans@edgeestimates.us. If your drawing set is incomplete or still in design development, note that in your submission — we will confirm what is achievable at that stage before you commit to anything.
Useful information to include:
We will send a fixed-fee quote within 2 hours. The estimate is delivered in 24 to 72 hours of quote approval. Both the Los Angeles and Dallas offices handle subcontractor inquiries.
Questions subcontractors, specialty trades, and project managers ask before sending drawings to Edge Estimates.
Edge Estimates charges $250 to $2,500 per estimate on a fixed-fee basis. Single-trade takeoffs for small to mid-size projects start around $250, while multi-trade packages covering several CSI divisions typically run $800 to $2,500. Fees are based on drawing count and scope complexity rather than your contract value. You receive a firm quote within two hours of sending drawings, and nothing is owed until you approve it.
Most single-trade takeoffs are delivered within 24 hours of quote approval. Multi-trade packages covering two to four divisions take 48 hours, and large multi-division commercial scopes take 48 to 72 hours. The fixed-fee quote itself comes back within two hours of receiving your drawings. If your bid deadline is tighter than the standard window, note it in your submission and we will confirm feasibility before you commit.
A quantity takeoff measures physical materials — linear feet of conduit, cubic yards of concrete, square feet of drywall, tons of steel. A cost estimate applies current material pricing, labor hours, and equipment costs to those quantities to produce a total. Edge Estimates delivers both as standard. If you price internally and only need verified quantities, request a quantity-only takeoff and the fee is adjusted accordingly.
At minimum, a drawing set — PDF, DWG, DXF, DWF, RVT, or clear images all work. Specifications and addenda should be included where available, since material grades, finish levels, and testing requirements carry real cost that drawings alone do not show. Also include the project zip code for pricing, your bid deadline, the trades you need covered, and whether labor should be union, open-shop, or prevailing wage.
Yes. Working from partial sets is routine, particularly for early budget pricing and design-development bids. When information is missing we document the specific assumption made and flag the item as requiring field verification or drawing clarification. You receive a usable number plus a clear list of what still needs confirmation, rather than a false sense of precision.
Yes, and we recommend it. Send your fully burdened labor rates — union scale, prevailing wage, or negotiated open-shop — and we apply those instead of published averages. The same applies to structure: the default is CSI MasterFormat, but if your accounting system runs on internal cost codes or UniFormat we build the workbook in that format so it imports without rework.
It depends on your bid volume. A full-time estimator’s salary plus takeoff software licenses represents a significant fixed annual cost, so if you bid a handful of projects a month, per-project pricing is usually the better economics. Once you are consistently bidding twenty or more projects monthly, the math starts favoring an in-house hire. Many subcontractors run both: an internal estimator on core work, outsourced support during peak periods.
Accuracy depends primarily on document quality. With a complete drawing set and specifications, a detailed trade takeoff should land within a few percent on quantities — measurement from drawings is objective work. Cost accuracy carries more variance because it depends on current material pricing, your actual crew productivity, and market conditions. This is why every deliverable states its labor and pricing basis explicitly: you can validate the assumptions against your own history before submitting.
Yes, and it is one of the more valuable parts of the service. When a general contractor divides a project into trade packages, work at the seams often goes unassigned — firestopping, housekeeping pads, temporary services, cutting and patching, final cleaning. We flag these in a written clarification list you can send to the GC before bid day, and document them as exclusions in your scope notes so your position is on paper if the question arises after award.
Yes. For a bid review we take your numbers and the drawings, produce an independent takeoff, then reconcile the two line by line and report where they diverge and why. Subcontractors typically use this on bids large enough that a 15% error in either direction would materially affect the year. It is also useful for onboarding a newer estimator, since the reconciliation shows exactly which assumptions differed.
Yes. Drawings, specifications, and bid documents sent to Edge Estimates are used solely to prepare your estimate and are never shared with third parties. If your project requires a formal NDA before documents change hands, contact us first and we will execute one prior to receiving anything.
Yes. Change order pricing is prepared from the original takeoff, so the delta is documented — original quantity, revised quantity, the difference, and the cost impact including any productivity loss from resequencing or out-of-order work. Having the baseline already on paper is what keeps a change order discussion short and factual.
