BIM models are coordinated. Your estimate should be too. Counting from PDFs ignores the work already done in Revit, Navisworks, or BIM 360. That is why contractors and developers use our BIM estimating services. We extract quantities directly from your 3D model. No manual tracing. No missed clashes. Just accurate, bid-ready numbers.

BIM estimating services means using your Building Information Modeling (BIM) model, not flat 2D drawings to produce quantity takeoffs and cost estimates. We extract data directly from the 3D model. Every wall, duct, pipe, structural beam, and piece of MEP equipment is already there. We simply read it, validate it, and price it.
This is model-based estimating, not manual counting. The difference is speed, accuracy, and coordination.
Traditional estimating from PDFs takes days. Errors slip in. You miss clashes. With BIM cost estimating services, you get a digital workflow: the model gives you quantities automatically. The estimator applies cost data. You get a reliable bid.
We provide BIM quantity takeoff services for projects where coordination matters most:
Office towers, retail, mixed-use
Manufacturing plants, warehouses, distribution centers
Pump stations, treatment plants, transit facilities
Multi-family, high-rise apartments
Why switch from 2D takeoffs to 3D estimating services? Here is what actual project teams report:
Manual counting from drawings misses items. BIM extraction does not. The model either has a pipe or it does not. We count exactly what exists.
On a recent commercial project, the team caught 47 coordination issues before breaking ground. The BIM estimate flagged quantity mismatches between structural and MEP models. That is real rework avoided.
BIM construction estimating forces everyone to use the same data source. The structural estimator, the MEP estimator, and the GC all work from the same model. Disputes drop.
What takes three days on PDFs takes four hours from a clean BIM model. You bid for more jobs. You respond to RFPs faster.
When your estimate matches the coordinated model, surprises on site shrink. Change orders still happen, but not because someone forgot to count the fire dampers.
We do not treat BIM as a gimmick. Every service below is delivered from your actual 3D model, not redrawn or re-entered manually.
Direct extraction of material quantities: concrete volume, rebar weight, drywall area, pipe length, duct surface area, cable tray length, and more.
We apply current material and labor rates to the extracted quantities. Location-specific. Trade-specific.
We do not just count everything. We check for obvious clashes. If a duct runs through a beam, we flag it. Your estimate should reflect what can actually be built.
Structure, architecture, MEP, finishes. Separate sheets for concrete, steel, HVAC, electrical, plumbing, fire protection.
A clean Bill of Quantities formatted for your bid package or procurement team.
You send a Revit or IFC model. We return an Excel estimate with takeoff sheets, cost summary, and model screenshots showing what we counted.
We follow a repeatable, transparent workflow. No guesswork. No black boxes.
You upload your Revit (.rvt), IFC, or Navisworks (.nwd) file. We also accept BIM 360 links. Tell us your project location and any specific cost codes y
We open the model in Revit or Navisworks. We check for view templates, worksets, and phase filters. Not every element in the model is bid-ready. We identify what is included and what is not.
Using schedules, filters, and takeoff tools, we pull quantities by category, material, size, and system. This is pure data extraction. No manual tracing. No ruler on a PDF.
We map extracted quantities to your cost database or our own. Labor rates are local. Material pricing is current. We do not use national averages.
You receive an Excel workbook with: Quantity summary sheets, cost breakdown by system and trade, model screenshots showing counted elements, inclusion/exclusion notes or any clashes or coordination issues we spotted.
To show you we actually do this work, here is a real example from a recent 120,000 sq ft office building.
Structural quantities extracted from Revit:
Concrete: 2,847 CY (foundations, columns, slabs)
Rebar: 287 tons (by bar size)
Structural steel: 412 tons (beams, columns, bracing)
MEP quantities extracted from the same model:
Ductwork: 8,430 LF (supply, return, exhaust – by gauge)
Pipe: 6,210 LF (hydronics, domestic water, sanitary – by diameter)
Cable tray: 1,120 LF
Lighting fixtures: 412 ea (by type)
Material breakdown delivered: Concrete by mix design. Steel by grade. Duct by gauge and insulation thickness. Pipe by material (copper, steel, PVC).
We do not guess. We read the model and show you exactly where each number came from.
Not every project needs model-based estimating. If your job is small and simple, PDF takeoffs work fine. But if you fit any profile below, digital estimating services are the right call.
You already model everything. Why step backward to 2D for pricing?
You manage coordination across trades. A model-based estimate gives you one source of truth
You need reliable budgets during design phases. Models change fast. Your estimate should keep up.
You design in 3D. You want to validate quantities against your own model before issuing a bid.
Let us be direct. Here is the real difference.
| Traditional 2D Estimating | BIM Model-Based Estimating |
|---|---|
| Manual counting from PDF or paper | Automated extraction from 3D model |
| High risk of missed items | Quantities match the model exactly |
| No clash checking | Clashes visible before pricing |
| Separate takeoffs per trade | Coordinated data from one model |
| Slow to update when design changes | Update in hours, not days |
| Estimator works alone | Estimator works with the model |
If your project has a BIM execution plan, you are already coordinating in 3D. Using traditional estimating on that project is a mismatch. You lose speed. You lose accuracy. You lose the benefit of all that modeling work.
BIM estimating means using a 3D Building Information Model, not flat 2D drawings as the source for quantity takeoffs and cost estimates. We extract data directly from the model. No manual measuring. No counting from PDFs. The estimate comes from the same model the design team coordinated.
We accept Revit (.rvt), IFC, Navisworks (.nwd, .nwc), and BIM 360 / Autodesk Construction Cloud links. PDFs alone are not enough for real BIM estimating. We need the actual model. If you only have PDFs, we recommend our traditional takeoff services instead.
If your model is LOD 300 or higher, our extracted quantities are typically within 2–3% of actual field quantities for measurable items like concrete, steel, ductwork, and piping. If your model is still early (LOD 200), accuracy is lower. We tell you upfront what level of confidence to expect.
Small models under 50 MB: 24 hours. Large or complex models: 2 to 3 business days. Rush delivery available for an additional fee. We confirm delivery timing within 4 hours of receiving your model. No surprises.
Pricing is based on model size, complexity, and deliverable depth. Small Revit model for a 10,000 sq. ft. office shell: 400–400–700. Full commercial building with MEP, structure, and architecture: 1,200–1,200–2,500. You get a fixed price before we start. No hourly billing.
