Accurate 5D BIM cost estimates extracted directly from Revit models for architects, engineers, developers, and contractors across all 50 US states. Architectural · Structural · MEP. 24–48 hours. Starting at $200.
The construction industry is shifting rapidly from 2D drawing-based estimating to model-based estimating and for good reason. A contractor who estimates from 2D drawings manually measures every wall, slab, beam, and duct run by hand. On a complex commercial project, this takes 40 to 90 hours. BIM estimating cuts that to 8 to 20 hours because the model has already measured everything. The quantities are embedded in the model elements. The estimator's job shifts from counting to analyzing: reviewing model quantities, applying local pricing, identifying scope risks, and producing a defensible cost breakdown.
For architects and engineers, BIM estimating enables something that traditional estimating cannot: real-time cost feedback during design. When the architect changes a wall from CMU to glass curtain wall, the cost impact updates immediately. When the structural engineer resizes beams, the steel weight and fabrication cost changes instantly. Design decisions that used to take weeks to cost out can be evaluated in hours keeping projects on budget from concept through construction documents.
CES provides BIM estimating services for every discipline and every building type architectural, structural, and MEP estimating from Revit models, IFC files, and all major BIM formats. We work with architects delivering design-stage cost checks, engineers validating structural costs, contractors pricing design-build proposals, and developers verifying construction loan budgets before financial close. Every estimate uses RSMeans 2026 zip-code pricing for your specific project location. Fixed price. NDA protected. 24 to 48 hours.
BIM is not just 3D modeling it is a multi-dimensional data platform. Each dimension adds a layer of information and value to the project model:
BIM estimating serves every AEC professional who works with digital models and needs accurate cost data from the architect sketching early design options to the contractor pricing a final construction document package.
CES BIM estimating covers all three primary BIM disciplines architectural, structural, and MEP plus site work, finishes, and specialty systems. Every estimate delivered with full quantity backup from model elements.
Industry research consistently shows that BIM-based estimating outperforms traditional 2D estimating in accuracy, speed, and cost recovery. Here is how the numbers compare:
LOD matters in BIM estimating. A Level of Development (LOD) 100 model is a massing model estimates from it carry high uncertainty. A LOD 300 model has fully developed geometry with material specifications CES estimates from LOD 300 models achieve ±5-8% accuracy. A LOD 400 model includes full fabrication-level detail estimates achieve ±2-5% accuracy, comparable to a contractor's detailed bid. CES works with models at any LOD and documents accuracy expectations clearly in every estimate.
CES accepts BIM models in every major format. Send us your Revit model, IFC file, or any other BIM format - we extract quantities and apply pricing without requiring you to change your workflow.
The accuracy of a BIM estimate depends on the Level of Development (LOD) of the model. A higher LOD means more detail in the model - and more accurate quantities. Here is what to expect at each LOD level:
| LOD Level | Model Detail | Estimate Accuracy | Best For | CES Delivers |
|---|---|---|---|---|
| LOD 100 | Massing model only - no element geometry | ±25–35% | Concept stage feasibility | SF-based budget estimate |
| LOD 200 | Approximate geometry - size, shape, location | ±15–20% | Schematic design budget | Assembly-based estimate |
| LOD 300 | Accurate geometry with material specs | ±5–10% Good | Design development & GC bidding | Full line-item estimate |
| LOD 350 | Interfaces and connections defined | ±4–8% Good | Construction documents | Detailed trade estimate |
| LOD 400 | Fabrication-level detail - shop drawing ready | ±2–5% Best | Subcontractor pricing | Bid-ready detailed estimate |
| LOD 500 | As-built conditions - field verified | ±1–3% Highest | As-built cost verification | Final cost reconciliation |
Don't know your model's LOD? Send it to us - we review the model and confirm the LOD level before providing your fixed quote. If LOD is lower than needed for your accuracy requirements, we'll tell you exactly what additional model development is needed and what it will cost to estimate with the detail you need.
Designed for architects, engineers, and contractors who need accurate cost data from their BIM models - fast, without disrupting their design workflow.
We had a complete LOD 350 Revit model but no in-house estimator. CES extracted quantities from our model and delivered a full CSI estimate in 40 hours. The GC bids came in within 6% of CES numbers. That's the most accurate design-stage estimate we've ever had.
We build Tekla models for every structural project. CES takes our Tekla exports and turns them into complete Division 03 and 05 cost estimates in 24 hours. Steel tonnage, rebar weight, concrete volumes - all extracted from the model. Our structural estimates are now as accurate as our models.
We do design-build - I need cost checks at every design milestone. CES gives me a BIM estimate at SD, DD, and CD stage. Each time, they update from our Revit model. By CD stage, our internal estimate and CES BIM estimate are within 4%. No more budget surprises at construction start.
