BIM Clash Detection Cuts Design Conflicts from 45 Days to One on Patimban Toll Access Project
The public works project team reports 1,350 person-days of rework prevented and benefits at 2.46 times implementation cost, with 264 drawings approved through a common data environment.
The Patimban access toll Package 3 project, executed by a Hutama Karya-Jaya Konstruksi joint operation under public works ministry supervision, has published concrete figures on its building information modeling program, reported by Konstruksi News on 13-14 November. Clash detection through the digital model resolved design conflicts in one day, against roughly 45 days when resolved in the field, preventing an estimated 1,350 person-days of rework and 270 equipment-days, and avoiding around 83 tons of CO2e. Coordination across three parties ran through a common data environment with 264 approved drawings, alongside drone surveys, load scanning, AR and 4D modeling. The team calculates benefits at 2.46 times implementation cost - a project-team figure, not an independent audit.
The disclosure matters because specific BIM return-on-investment numbers are rare in Indonesian public works. With BIM already cited at the IKN MPR building project, the Patimban figures signal that digital delivery is being normalized as an execution standard on flagship ministry projects - a shift that pulls document management, drawing approval and field-data integration into the project technology stack.
