Case Study: Klorman Construction saves over 8,000 man-hours per project and accelerates delivery with Trimble's Prolog and BIM solutions

By Standardizing on Prolog® Software Integrated with BIM, Klorman Construction has Increased Efficiencies to Save over 8,000 Man Hours a Year on Every Project

Klorman Construction is a California-based design‑build and structural concrete contractor (≈200 employees, ~$150M revenue) known for complex parking structures, towers and airport work such as LAX Tom Bradley. Faced with the need to deliver higher-quality work faster and cheaper while managing large, document‑intensive projects and thousands of RFIs/PCOs, Klorman needed a standardized, centralized project management approach to control cost, communication and risk.

Klorman standardized on Meridian’s Prolog Manager and Prolog Converge integrated with Tekla BIM and Trimble RTS, linking intelligent BIM models to a single project database to automate RFIs/PCOs, improve document control and enable powerful querying. The result: average team sizes reduced by four people (about 8,300 man hours saved per project per year), faster start‑up/close‑out, more predictable project delivery, frequent bid savings of ~$160K, and stronger risk mitigation through instant access to project records.
