Why BIM Cost Analysis Matters

A BIM model can contain a large amount of information about a building's geometry, materials, components, and systems.

Cost analysis adds another layer by evaluating how those modeled components contribute to the overall construction budget.

This can help project teams identify major cost drivers and evaluate the financial effect of design decisions.

What Is Included in BIM Cost Analysis

  • BIM model review
  • Quantity analysis

  • Unit-cost review
  • Material costs
  • Labor costs
  • Equipment costs where applicable
  • Cost-per-square-foot analysis
  • Design-change analysis
  • Budget comparison
  • Cost-driver identification
  • Value engineering support
  • Allowance review
  • Assumptions
  • Exclusions
  • Cost summary
  • Editable analysis deliverable

BIM-Based Trade Cost Analysis

BIM cost analysis can organize costs across modeled construction scopes such as:

  • Sitework
  • Concrete
  • Rebar
  • Structural steel
  • Framing
  • Roofing
  • Exterior walls
  • Doors and windows
  • Insulation
  • Drywall
  • Flooring
  • Ceilings
  • Millwork
  • HVAC
  • Plumbing
  • Electrical
  • Fire protection
  • Other modeled systems

Identifying Construction Cost Drivers

Not every modeled component has the same effect on the project budget.

BIM cost analysis can help identify high-cost building systems, materials, quantities, and design components that contribute significantly to the overall construction cost.

Design Option & Value Engineering Analysis

When multiple design approaches are being considered, model-based quantities can provide a basis for comparing their potential cost implications.

This can support value engineering discussions involving materials, assemblies, building systems, and other design decisions.

BIM Cost Analysis for Design Development

As project models become more developed, the associated quantities and cost information can be refined.

This allows cost analysis to become more detailed as project information improves.

BIM Cost Analysis for California Projects

We provide BIM cost analysis services throughout California for owners, developers, architects, general contractors, subcontractors, and construction professionals.

Working With BIM and Project Documents

BIM models can be reviewed alongside:

  • Construction drawings
  • Specifications
  • Schedules
  • Material information
  • Cost databases
  • Existing estimates
  • Project budgets
  • Other relevant project documents

Using supporting documentation can help address information that is not adequately represented in the model.
