5D BIM Cost Estimation
Tie every dollar in your estimate to a real element in the model. Powerkh integrates 3D geometry, the construction schedule, and cost data into a live 5D workflow — so quantities, cost plans, and cashflow forecasts update the moment the design does.

5D BIM Cost Estimation Services
5D BIM is the practice of linking cost data to a 3D model and its construction schedule, adding quantity, cost, and time as extra dimensions. Cost items map directly to model elements, so quantities, cost plans, and time-phased cashflow forecasts update automatically whenever the design changes.
Traditional estimating starts over with every design revision: quantities are re-measured, spreadsheets are re-built, and by the time the numbers land, the design has moved on. 5D BIM breaks that cycle by mapping cost items directly to model elements. When a wall type changes or a floor grows, the affected quantities and their cost consequences surface immediately — traceable back to specific objects, not a line in a spreadsheet nobody can verify.
Powerkh sets up and runs the full 5D workflow: structuring the model for measurement, extracting quantities, assembling cost plans, and connecting them to the schedule for time-phased cashflow. Across 400+ delivered BIM projects for US, UK, and European clients, we work in imperial units by default (metric fully supported) and align the cost breakdown to whatever structure your estimators already use.
Why Estimate from the Model
Quantities you can audit
Every quantity traces to specific model elements, so estimators can verify measurements visually instead of trusting a spreadsheet cell.
Estimates that track the design
When the model is revised, linked quantities and costs update with it — no re-measuring drawings after every design iteration.
Cashflow tied to the schedule
Connecting cost to schedule activities produces time-phased expenditure curves owners and lenders can plan funding around.
Changes priced before approval
Model-based costing shows the budget impact of a proposed change while it is still a proposal — not after it is built.
Our 5D BIM Services
Model-based quantity extraction
Structured quantities pulled from Revit or IFC models, organized by your cost breakdown structure and ready for pricing.
Cost plan development
Element quantities assembled into cost plans and budget estimates that evolve with the design from concept through construction documents.
Cashflow forecasting
Costs distributed across schedule activities to produce monthly expenditure forecasts and S-curves for funding and draw planning.
Change-impact costing
Quantity and cost deltas between model versions, so every design change or variation comes with a defensible price tag.
Value engineering support
Side-by-side quantity and cost comparison of design alternatives to show exactly where savings come from — and what they trade away.
Model audit for costing
Review and correction of model structure, naming, and parameters so extracted quantities are complete and measurement-ready.
Our 5D BIM Process
-
Share your project data
Send your model, schedule, and cost breakdown structure or rate library. We review everything and return a free quote.
-
Model verification
We audit the model for measurement readiness — checking element classification, parameters, and modeling gaps that would distort quantities.
-
Quantity and cost mapping
Quantities are extracted and mapped to cost items in your breakdown structure, with unit rates applied from your library or agreed benchmarks.
-
Schedule integration
Cost items are linked to schedule activities to generate time-phased budgets, cashflow curves, and earned-value baselines.
-
Delivery and revisions
You receive the cost plan, quantity reports, and cashflow forecasts — refreshed against each new model and schedule revision as the project moves.

FAQ
What do you need from us to start a 5D BIM project?
A 3D model (Revit or IFC), your cost breakdown structure or estimating template, and — for cashflow work — the project schedule. If you only have 2D drawings, our modeling team builds the BIM model first.
How is 5D BIM different from a standalone quantity takeoff?
A quantity takeoff delivers measured quantities for your estimators to price. 5D BIM goes further: quantities stay linked to the model and the schedule, so costs update with design changes and can be phased over time as cashflow.
Do we need a 4D schedule before starting 5D?
No. Quantity extraction and cost planning work from the model alone. A 4D model–schedule link, which we also build, unlocks cashflow forecasting — the two dimensions complement each other but can start independently.
What deliverables do we receive?
Structured quantity reports mapped to your cost breakdown, the cost plan or estimate, cashflow forecasts and S-curves where a schedule is linked, and change-impact summaries between model revisions.
How much do 5D BIM services cost?
We price hourly. After reviewing your model and requirements we send a free quote, sign an NDA on request, and you pay only after the work is delivered.
