BIM-based cost estimating: how to avoid errors and reduce costs by 10–15%

BIM-based cost estimating: how to avoid errors and reduce costs by 10–15%

The classic problem: designers model one thing, estimators calculate another, and contractors build a third.
This leads to cost overruns, disputes, delays, and discrepancies in material quantities.

BIM-oriented cost estimating solves this issue by taking quantities, specifications, and data directly from the model.

Why model-based estimates are more accurate

When the model is structured, correctly filled out, and compliant with standards, the estimator receives:

  • Actual work volumes
  • Precise specifications
  • Up-to-date materials and elements
  • Automated calculations and schedules

This eliminates subjectivity and manual errors.

What prevents model-based estimating

Key challenges include:

  • Incorrect model structure
  • Empty or incorrect parameters
  • Lack of unified classification systems
  • Disorganized libraries

Until these are addressed, model-based estimating is impossible.

Tools that make estimating fast and accurate

Modern solutions like Larix automate:

  • Quantity calculations
  • Preparation of local estimates
  • Specifications
  • Resource schedules
  • Cost accounting and comparative analysis

How NLB Company helps take estimating to the next level

NLB Company works with the Larix estimating platform and structures the process so that the model truly becomes the source of all data:

  • BIM model audit before estimating
  • Configuration of classifiers, parameters, and filling rules
  • Integration of Larix into company workflows
  • Training estimators and designers to work collaboratively
  • Data quality control to ensure accurate calculations

The result: fewer errors, fewer disputes, and a real reduction in design and construction costs.
