Accurate quantities are critical before issuing GMP packages. Our BIM estimating team extracts LOD 300 takeoffs directly from your Revit models, tracking every element with precision from rebar and piping to fittings and assemblies. We link model data to schedules, provide clash insights, and focus on cash flow forecasting and waste control to protect your project finances. Early identification of issues enables proactive planning rather than reactive fixes. All estimates are delivered with CSI based breakdowns, ensuring what gets built matches exactly what the model shows.
COMET Estimating creates BIM models that bring your U.S. projects to life in 3D. Walk through complete buildings digitally. Spot clashes early. Coordinate teams smoothly. Reduce change orders and stay on budget.
Every bolt, pipe, and rebar is counted according to your model. No guesswork. Matches what builds exactly.
Conflicts between MEP and structure were identified early. Correction in model space. Save 10x field rework costs.
Takeoffs relate to Primavera tasks. Cash flow curves match phasing. Stay under budget for the whole job.
Model quantities return the guaranteed maximum price. There will be no disputes in the future. Builds trust fast.
Waste from rebar, concrete, and MEP is calculated efficiently. Order precisely. Cut overages 5 to 10%.

UK contractors choose Comet Estimating because we pull exact quantities from Revit models that match field reality perfectly. Our BIM takeoffs control budgets tight and catch clashes before they cost thousands in rework.
We extract LOD 300 quantities from your exact Revit files matching site conditions and phasing. Every bolt, rebar ton, and pipe foot counts accurate, not estimated.
Takeoffs tie direct to Primavera tasks for cash flow curves and critical path pricing. Accurate numbers win guaranteed maximum price contracts confidently.
Full reports deliver on time with same day reruns when designs change. Clear progress tracking keeps your BIM estimates current through every revision.
Whether you handle a few projects or many, our estimating support grows with your business.
We turn your BIM files into detailed cost data before GMP locks in so budgets stay tight. Teams get Excel exports, cash flow curves, and change logs keeping estimates current through design.
We build trusted relationships by delivering model based estimating across full project lifecycles. Reliability comes from complete element queries, waste factors by the CSI division, and profit matching builds.
Please use your Revit or Navisworks files to extract all counts. LOD 300 gets down to bolts and bars. Tags link straight to dollars.
Reports land in 4 to 6 days for whole buildings. Updates run 24 hours per change. Monitor the progress at your location on a daily basis.
Tie costs right to your tasks and steps. Codes match your planning software. Cash curves run month to month.
Load all trades and get clash lists with pics. Pipes vs ducts show counts clear. Fix cheap before pouring.
LOD 300 nails nuts to feet of pipe. Waste adds smart by section. Matches what you measure in field.
New model runs full fresh same day. Log shows what shifted and dollar hit. Bid stays bang up to date.
Sheets drop right into your program no fuss. Formulas work for your tests. PDFs back up the details.
Grab pipes, ducts, wire from your picks. Counts and gear link to timelines. One report covers it all.
Run budgets on real model numbers not hunches. 35+ BIM teams use us daily. Win tight with no waste shocks.
4+ years line up takeoffs to what actually builds. 1,500+ jobs find every piece. Finish under budget easy.
