What is 5D BIM?

5D BIM (Five-Dimensional Building Information Modeling) adds the cost dimension (the 5th dimension) to the traditional 3D BIM model.

3D BIM = geometry (the physical model)
4D BIM = time (construction sequencing and scheduling)
5D BIM = cost (estimating and cost management)

So, in simple terms:

5D BIM = 3D Model + Time + Cost

How 5D BIM Relates to Cost Management

1. Automated Quantity Take-off

The BIM model contains detailed information about every component (e.g., materials, sizes, volumes, counts).
5D BIM tools automatically extract quantities directly from the model, saving time and reducing manual errors compared to traditional take-offs from 2D drawings.

Example:

If you change a wall’s size or material in the model, the quantity take-off and cost estimate update automatically.

2. Dynamic Cost Estimation

Costs are linked to model elements — so when the design changes, costs update in real time.
Estimators can instantly see how design changes affect total cost, helping teams make better, data-driven decisions early.

Example:

Changing a concrete floor to steel decking instantly updates total project cost and budget projections.

3. Budget and Cash Flow Forecasting

Because 5D BIM integrates time (4D) and cost (5D), it enables cash flow forecasting throughout the project timeline.
You can visualize how costs will be incurred at different construction stages — useful for financial planning and client reporting.

4. Value Engineering

5D BIM supports scenario testing: you can quickly model “what-if” options to find cost-effective solutions without compromising quality.
This makes value engineering much faster and more precise.

5. Improved Collaboration and Transparency

Everyone (client, contractor, designer, quantity surveyor) can access the same model-based cost data.
This reduces disputes and improves communication, since cost information is linked directly to a visible, shared 3D model.

6. Lifecycle Cost Management

Beyond construction, 5D BIM can support facility management by tracking long-term operational and maintenance costs of building components.
This promotes whole-life cost management, not just initial capital cost control.

5D BIM software integrates the 3D design model with cost data (and often scheduling, for 4D). The choice of software depends on whether you’re working in design, estimating, or project control, but the goal is the same: link model elements to cost information for accurate, real-time cost management.

🧰 Common 5D BIM Software Tools

1. Autodesk Revit + Cost Management Tools

Revit creates the 3D/4D model (geometry + data).
For 5D, Revit links with:
Autodesk Cost Management (via Autodesk Construction Cloud) – built-in cost control and budgeting platform.
Navisworks Manage – combines 3D models, schedules, and cost data for simulation.
CostOS, Sage Estimating, or Innovaya – third-party plugins for cost estimation.

Use case:

Architects and QSs using Revit for model-based design and cost estimation.

2. CostOS (by Nomitech)

Purpose-built 5D BIM estimating platform.
Directly imports BIM models from Revit, ArchiCAD, or IFC formats.
Generates automated quantity take-offs and links with cost databases.
Supports parametric and traditional estimating in one system.

Use case:

Quantity surveyors and cost engineers who want powerful cost modeling linked to BIM.

3. Bentley SYNCHRO 5D

Integrates 3D, 4D (time), and 5D (cost) in one environment.
Useful for construction planning, cash flow forecasting, and project control.
Links with schedules (Primavera P6, MS Project) and cost data.

Use case:

Contractors managing complex infrastructure or construction sequencing with cost tracking.

4. Navisworks Manage + Estimating Add-ons

Often used as a 4D/5D visualization platform.
Can integrate with cost databases or Excel to simulate cost-loaded schedules.
Enables visualization of cost progression over time.

Use case:

Project managers visualizing cost and time impacts on a unified model.

5. iTWO (RIB Software)

One of the leading enterprise-level 5D BIM platforms.
Integrates design, estimating, scheduling, and procurement.
Used for large-scale projects with real-time cost and schedule control.

Use case:

Large contractors and developers for integrated project delivery and cost governance.

6. Vico Office (Trimble)

Developed specifically for model-based estimating and scheduling.
Supports 3D (model), 4D (schedule), and 5D (cost).
Connects BIM quantities with cost items and enables cost forecasting.

Use case:

Construction managers using model-based estimating and “location-based scheduling.”

7. ArchiCAD + BIMx + Cost Integration

ArchiCAD can export IFC models to cost management tools like CostOS or Sage Estimating.
Some plugins (e.g., BIMestiMate, Simplebim) support direct 5D integration.

Use case:

Architects and designers working in ArchiCAD who want to connect their models to cost workflows.
