BIM 5D is the integration of cost with the BIM model and its schedule. While 3D BIM describes the geometry and 4D adds time, 5D tells you how much each element costs, when it will be built and, if it is connected to project management, how much it has actually cost.
In this article we explain what BIM 5D is, what you need to apply it and how to build a workflow that links the cost estimate, scheduling and project costs.
If you are interested in the specific task of getting quantities and cost estimates from Revit and IFC, read BIM 5D cost estimating: getting costs from Revit and IFC.
The dimensions of BIM
- 3D – Geometry: the model with its elements and properties.
- 4D – Time: each element linked to a schedule activity.
- 5D – Cost: each element linked to line items and prices.
- 6D – Sustainability and 7D – Operations and maintenance (the numbering of these last two dimensions varies by source).
If you are just getting started, read what the BIM methodology is.
"Real" BIM 5D: from planned cost to actual cost
BIM 5D is often reduced to simply getting a cost estimate out of the model. But the real value appears when the model, the estimate and the schedule are connected to what happens on site:
- Model → quantities.
- Quantities + prices → cost estimate.
- Cost estimate + schedule → production curve and planned cost over time.
- Actual progress → earned value and progress certifications.
- Purchases, timesheets and invoices → actual cost.
- Comparison → variances and decisions.
Steps 1 to 3 are 5D planning; steps 4 to 6 are 5D control. For this second part you need a management system, usually an ERP.
Requirements for applying BIM 5D
A prepared model
- Categorized elements and well-defined types.
- A classification code on every element (Assembly Code, Uniformat, Uniclass or your own coding).
- A level of information appropriate to the project phase.
A coded price library
A database of unit prices whose codes match the model's classification.
A linked schedule
Activities from the construction schedule associated with model elements or cost estimate line items.
A project control system
Software where progress, purchases, work reports and invoices are recorded and charged to line items.
Agreements between teams
Measurement criteria, coding and update frequency agreed between modelers, the technical office, planning and production, ideally set out in the BIM Execution Plan (BEP).
BIM 5D workflow step by step
1. Quantities from the model
Export quantities from Revit (schedules or material takeoffs) or from IFC (quantity sets). See the practical case in Revit and Odoo integration.
2. Cost estimate
Quantities are matched to the price library by code. Line items the model does not measure (auxiliary means, safety, waste, indirect costs) are added. You can also complement it with estimates in BC3 (the Spanish FIEBDC-3 data exchange format).
3. 4D scheduling
Elements or line items are linked to schedule activities. This lets you simulate the construction sequence and obtain the planned production month by month (S-curve).
4. Execution and progress
During construction, progress is recorded: quantities executed per line item, or elements marked as built in the model. That progress feeds the progress certifications.
5. Actual cost
Purchases, subcontracts, work reports and equipment are charged to each line item.
6. Analysis
With planned cost, progress and actual cost you calculate earned value (CPI, SPI, EAC) and detect variances. See how to control project costs.
7. Changes
When the design changes, you update the model and export quantities again. The cost estimate, the schedule and the forecast at completion are updated with far less rework.
Benefits of BIM 5D
- Faster, more accurate estimates, since they start from model quantities.
- Immediate assessment of the financial impact of design changes.
- Cash flow forecasting based on planned production.
- Traceability between model, estimate, certification and cost.
- Fewer disputes with the client and subcontractors, because quantities come from a shared model.
- Historical data that can be reused in future bids.
Common challenges
- Models that are not built with measurement in mind.
- No shared coding between the model and the estimate.
- Disconnected tools: the model in one, the estimate in another, the schedule in another and costs in an ERP.
- Resistance to change within the teams.
A good way to tackle them is to start with a limited pilot, define the coding and connect the tools through open formats (IFC, BC3) and integrations.
Tools for BIM 5D
- Modeling: Revit, ArchiCAD, Allplan, Tekla.
- Quantity takeoff: Revit schedules, Navisworks, CYPE Open BIM Quantities, add-ins for estimating software.
- Estimating and 5D: Presto, CYPE Arquímedes, RIB iTWO.
- Scheduling: Microsoft Project, Primavera P6.
- Control and ERP: BIM 2.0 for Odoo, which imports quantities from Revit and estimates from BC3 and Excel, integrates with Microsoft Project and connects everything to purchasing, certifications, earned value and accounting.

Frequently asked questions
Is BIM 5D only for large companies?
No. A small contractor can apply BIM 5D by importing quantities from Revit into its ERP and linking them to prices and progress, without needing complex platforms.
What is the difference between BIM 4D and 5D?
4D adds time (scheduling); 5D adds cost. In practice they are used together.
Do I need an ERP to do BIM 5D?
For the 5D cost estimate, no. For 5D control (comparing against actual cost), yes, you need a system that records the project's costs.
Conclusion
BIM 5D is not a tool, it is a workflow: model → cost estimate → schedule → progress → actual cost → decisions. Companies that connect this workflow from start to finish work with more reliable estimates and have more information to protect the profitability of every project.
