BIMformed: Machine learning framework for predicting and preventing defects in buildings

Funded by Innovate UK, Silvia Cirstea, Razvan Dinita and Javad Zarrin from the School of Computing and Information Science worked with industry partner TR Control Solutions to tackle the challenge of reducing errors in the construction industry.

Availability of data in the construction industry is a major barrier, as most building workers do not get their instructions via digital devices and records of errors are not kept in digital form linked to the construction specification.

To address this problem, the project developed a framework to collect and link up data from a number of sources, including workers’ profiles and understanding of task, captured via a web app, and construction task information extracted from specification models and design documents. AI techniques were used to devise automatic generation of questionnaires to assess operatives' knowledge and understanding of the task.

A machine learning framework, based on Support Vector Machines, was developed and shown to be able to predict the likelihood of construction defects with sufficient reliability and accuracy on a pilot data set.

Following the successful completion of this feasibility study with our partners in April 2020, collaboration continues to develop the framework into a commercial product.
