Automated code compliance checking through building information modelling

The design, construction and handing over of building projects need to comply with the rules set by the local authorities. However, manual assessment of the drawings and plans against variable and complex sets of rules is quite cumbersome, inconsistent, expensive and prone to human error, resulting in huge delays in construction projects. The aim of this research was thus to develop an automated code compliance (ACC) checking process using building information modelling (BIM). The drawbacks of manual code compliance were assessed through a review of the existing system. These were confirmed by 15 interviews with officials of the Capital Development Authority (CDA) in Pakistan. Feedback on the newly developed ACC system with BIM integration was sought through 30 interviews with customers and CDA employees. While the new programme of the code compliance reduced the time involved from 1 week to 6 h, customers were concerned about the additional expense of engaging an architect to develop a complete set of BIM models. ACC and BIM integration in local municipalities should raise the profile of Pakistan in industry innovations and pave the way to meeting several United Nations Sustainable Development Goals.
