BIM Estimating Services
We prepare BIM estimating services that turn your 3D model into an accurate cost estimate. Our estimators pull material quantities directly from the model, then link them to live pricing and your schedule using 5D BIM. You see the cost of every element, and when the design changes, the numbers update with it.

Accurate Cost Estimates Built Directly From Your BIM Model
BIM estimating services pull cost estimates directly from a 3D building model instead of measuring 2D drawings by hand. ACON Engineering takes your Revit or Navisworks model and extracts the quantities for every element, from structural beams, columns, and rebar to MEP ductwork, piping, and electrical conduits.
We work at LOD 300, so the takeoff matches what the project will actually build. We price each quantity with RSMeans and live market rates, then link the cost to your schedule through 5D BIM. When your design changes, the model updates and the cost recalculates, so your budget stays current. You also get clash detection that catches conflicts between trades before they reach the field, where fixes cost far more.
Complete BIM Estimating Services for Every Model
We cover the full BIM estimating workflow, from clash detection to 5D cost integration. Our estimators pull every quantity from your model and tie it to real pricing. Each service below is managed by certified BIM estimators who specialize in that work.
BIM Clash Detection and Resolution
We combine your architectural, structural, and MEP models into one and scan for conflicts before construction starts. Our team handles model aggregation, rule setting, and automatic scanning in Autodesk Revit. We move problem-solving from costly on-site rework to the virtual design phase.
BIM-Based Bid Management
We manage your full bid cycle using model-based data. Our certified BIM estimators turn your model into accurate quantities, organize them into a clear bid package, and support you through submission. You can rely on numbers that match the model.
5D Cost Estimation
We link your 3D model to scheduling data and material costs to give you a true 5D estimate. This connects quantity, price, and time in one place, so you plan your budget and your production around the same model with greater accuracy and control.
BIM Quantity Takeoffs
We extract material quantities directly from your model instead of measuring 2D drawings by hand. This removes the human error that manual takeoffs carry and gives you reliable, model-accurate data. You receive quantities you can trust for pricing and procurement.
Change Order Management
We quantify and track the cost impact of every design change in real time. When the model updates, we measure how the variation moves your budget and show you the new figure. You stay in control of cost through every revision.
Value Engineering
We review your model for alternative materials and methods that lower cost without weakening quality or safety. Our team compares the options and shows you where you can save, so you keep the design sound while bringing the budget down and improving overall project efficiency.
What We Deliver With Your BIM Estimate
You receive a model-based cost estimate you can bid and build from. We deliver a detailed cost breakdown by CSI division, a material and labor analysis, and a clash report that flags conflicts before the field. You also get your quantities in editable Excel, native BIM files, and 3D views that tie cost to each element.

Our 4-Step BIM Estimating Process
We follow a direct workflow to deliver your BIM estimates on time. You work with certified BIM estimators who help you bid and build with confidence.
01
Upload Your Model
You send us your Revit or Navisworks model with the project scope. Our team checks the model elements and confirms the level of development before we begin.
02
Model Validation and Quantity Extraction
We validate the model geometry, then extract the quantities for every element at LOD 300. Our estimators pull structural, architectural, and MEP quantities straight from the model.
03
Cost Integration and Clash Detection
We price each quantity with RSMeans and live market rates, then add waste factors by the CSI division. We also run clash detection to catch trade conflicts before they reach the site.
04
Review and Delivery
A senior estimator checks every quantity and cost against the model. We deliver your model-based estimate and clash report in editable Excel within 24 to 72 hours, so you can bid right away.
The BIM Estimating Software We Use
We prepare your estimate in the BIM cost estimating software the industry trusts. Our team works in Autodesk Revit and Navisworks to extract and coordinate model quantities, then prices each line with RSMeans and live market rates. These tools pull accurate data straight from your model and give you bid-ready numbers fast.
Why Contractors Trust ACON Engineering for BIM Estimating
ACON Engineering pulls accurate cost straight from your model, backed by certified BIM estimators. We help with every quantity, detect clashes, and price the work to your market, so you bid with numbers that match the model.
High Accuracy
We automate quantity extraction with BIM estimating software, which removes the manual errors, overlaps and omissions that 2D takeoffs carry. Our certified BIM estimators and engineers check every figure, so your estimate matches the model exactly.
Improved Clash Detection
We combine your MEP, structural and architectural models into one and flag conflicts before construction. This coordination catches issues early, prevents expensive on-site rework, and keeps every trade aligned around a single model.
Whole Life Cost Data
Your BIM model contains valuable asset data. We make sure it stays useful even after the project is built. You can apply it to future facilities management, maintenance planning and long-term cost forecasting.
15 Years of Experience
We bring over 15 years of estimating across a wide range of projects. Our certified estimators know every step of the BIM workflow and take a hands-on approach, so you work with a team that understands your project.
Top BIM Software
We work in leading BIM estimating tools, including Autodesk, Sage, Vectorworks and BIM Logic. These platforms pull accurate data straight from your model and let us coordinate every discipline in one place with greater accuracy and efficiency.
Comprehensive and Affordable
We offer a full range of estimating solutions under one roof at flexible, pay-per-project rates. You save up to 60% against an in-house team, with no long contracts and no drop in quality or service standards whatsoever.

Frequently Asked Questions (FAQs)
BIM estimating pulls cost estimates directly from a 3D building model instead of measuring 2D drawings by hand. Estimators extract material quantities from the model, then link them to live pricing. The result is a faster, more accurate estimate that updates when the design changes.
5D BIM adds cost and schedule to a 3D model. The three dimensions of geometry become four with time, and five with cost. This lets you see how a design change affects both your budget and your timeline in real time.
LOD stands for Level of Development, and it sets how detailed the model is. LOD 200 gives approximate quantities for early budgets. LOD 300 gives accurate quantities that match what the project will build. LOD 400 adds fabrication detail for shop-level takeoffs. We work at LOD 300 for bid-ready accuracy.
A traditional takeoff measures 2D drawings by hand, which is slow and open to human error. A BIM takeoff extracts quantities straight from the 3D model. You get faster results, fewer missed items, and quantities that update automatically when the model changes.
We work from Revit and Navisworks models. Our estimators extract and coordinate quantities in these tools, then price them with RSMeans and live market rates. If you have a different format, send it over and we will confirm we can work with it.
