Accurate 5D BIM cost models and model-based quantity takeoffs extracted directly from Revit and AutoCAD for design-build, commercial, and institutional projects nationwide.
DFE Estimators extract precise quantity takeoffs and 5D cost models directly from your Revit and AutoCAD BIM models, eliminating the time and error associated with traditional 2D blueprint takeoffs. 5D BIM adds cost as the fifth dimension to a building information model, linking every model element directly to a current price from RSMeans zip-code databases. This produces the most accurate cost estimate available at any stage of design. DFE supports all BIM Level of Development (LOD) stages from LOD 100 through LOD 500, and delivers all estimates in Excel format, organised by CSI division, in accordance with AACE standards, within 24 to 48 hours of receiving your model.
These are the four cost estimating problems that BIM project teams encounter most frequently.
Your BIM model is complete but your cost estimates are still being done manually from 2D drawings.
Every design iteration triggers a manual re-estimate. By the time new numbers arrive, design has changed again.
Extractng quantities manually from BIM models introduces counting errors that undermine the accuracy of the whole estimate.
Design-build projects move faster than traditional delivery. Manual estimating cannot keep pace with integrated project schedules.
DFE Estimating solves all four model-based 5D cost estimates extracted directly from your Revit files, updated automatically as design evolves, and delivered in 24 to 48 hours.
A four-step process that connects your BIM model directly to accurate construction cost data.
Upload your Revit (.rvt), AutoCAD (.dwg), or IFC file through our secure portal. We accept all major BIM file formats.
Your assigned BIM estimator reviews your model, confirms the Level of Development (LOD), and identifies any scope areas requiring 2D supplementary takeoff.
We extract all quantities from the model, link each element to RSMeans zip-code cost data, and build a complete 5D cost model covering all CSI trades.
You receive a complete Excel estimate by CSI division plus a colour-coded BIM cost report, all reviewed before delivery and ready for your bid or design decision.
Nine reasons construction professionals trust DFE for model-based cost estimating.
Model-based cost estimating across every project type and every BIM workflow.
Full 5D cost models extracted directly from your Revit model — every building element linked to current RSMeans cost data, updated as your model evolves through each design phase.
Precise material quantity takeoffs extracted digitally from Revit models — eliminating manual counting errors and delivering exact quantities by element, trade, and CSI division for immediate pricing.
Fast, model-driven cost estimates tailored to design-build project timelines — supporting integrated project delivery with accurate cost feedback at every design milestone without slowing the design-build schedule.
We identify and cost all BIM clash corrections before construction — quantifying the labour and material cost of coordination changes, giving GCs and owners a complete picture of clash resolution costs.
Estimate packages updated at each LOD milestone — from LOD 100 conceptual cost through LOD 400 detailed fabrication-level estimates — tracking cost against design as your BIM model develops.
Not every project uses Revit. DFE works with IFC, AutoCAD (.dwg), ArchiCAD, and other BIM formats — ensuring accurate 5D cost extraction regardless of the design software your team uses.

BIM estimating is the process of extracting construction cost data directly from a Building Information Model (BIM) — rather than performing manual quantity takeoffs from 2D drawings. By connecting model elements to a cost database, every structural component, wall, floor, roof, window, MEP system, and finish item can be priced automatically as the design evolves. BIM estimating is faster, more accurate, and automatically updates when the model changes — making it the most efficient estimating method for complex commercial and institutional projects.
5D BIM adds cost as the fifth dimension to a building information model. A standard BIM model contains 3D geometry (length, width, height). The fourth dimension (4D) adds construction schedule and sequencing. The fifth dimension (5D) adds cost — linking every model element directly to current pricing data so that the cost implications of any design change are immediately visible. DFE creates 5D BIM cost models by linking Revit model elements to RSMeans zip-code cost databases, delivering real-time cost feedback at every design milestone.
BIM estimating is significantly more accurate than manual 2D takeoff estimating because quantities are measured digitally from the model rather than counted by hand from drawings. Studies consistently show that BIM-based quantity takeoffs are 15 to 40% faster and carry 60 to 80% fewer counting errors than traditional 2D takeoffs. At LOD 300 and above, BIM estimates routinely achieve 95 to 99% accuracy against actual tender prices when linked to current local cost data — the highest accuracy available for construction estimating.
DFE Estimating works directly with Revit (.rvt files), AutoCAD (.dwg), ArchiCAD, and IFC files for model-based BIM estimating. We use Autodesk Revit’s native quantity scheduling tools and link model quantities to RSMeans cost databases for pricing. For BIM quantity surveying, we use Trimble. For MEP BIM estimates, we use FastPIPE and FastDUCT in combination with model geometry. All BIM estimates are delivered in Excel format organised by CSI division.
LOD stands for Level of Development — a framework that defines how much detail and reliability is contained in a BIM model at each design stage. LOD 100 is conceptual massing — allows order-of-magnitude cost estimates only. LOD 200 is schematic design — allows approximate quantity takeoffs. LOD 300 is construction documentation — allows precise quantity takeoffs and accurate cost estimates. LOD 400 is fabrication-level detail — allows shop drawing-level cost estimates. LOD 500 is as-built — allows facility management-level cost data. DFE supports all LOD levels.
BIM estimating service fees typically range from $300 to $3,000 depending on model complexity, LOD level, number of trades, and project size. Simple residential BIM takeoffs at LOD 200 to 300 generally start at $300 to $600. Full commercial 5D cost models at LOD 300 to 400 range from $1,000 to $3,000.

Yes. DFE Estimating works with BIM models at any stage of development — from an early LOD 100 massing model through to a complete LOD 400 construction model. For incomplete models, we supplement model-extracted quantities with traditional 2D takeoffs for any scopes not yet modelled, clearly noting which quantities came from the model and which were calculated conventionally. This hybrid approach ensures accurate cost estimates even when the BIM model is not fully complete.
Traditional estimating involves manually counting and measuring quantities from 2D construction drawings — a time-consuming, error-prone process. BIM estimating extracts quantities directly from a 3D digital model, linking every element to a cost database automatically. The key differences: BIM estimates are faster to produce, carry fewer errors, update automatically when the model changes, and can track cost implications of design decisions in real time. Traditional estimating is still necessary for projects without BIM models — DFE provides both services.
DFE Estimating is a trusted provider of construction estimating services, delivering accurate quantity takeoffs, material takeoffs, labor pricing, and bid-ready construction estimates for residential, commercial, and industrial projects. We help contractors save time, reduce estimating errors, and bid with confidence.
