About the Project

Building Information Modelling (BIM) has been increasingly adopted as a shared information resource and knowledge base for building and facility management. Property insurance companies can also leverage such information for pricing and underwriting. However, there are two major challenges for accessing as-built BIM data, including (1) the lack of as-built BIM models for many existing structures (e.g., old properties), and (2) deviations between BIM models and actual builds. Laser-scanning and photogrammetry methods have both been developed for as-built BIM reconstruction and enrichment, but the performance of such methods has been degraded due to the increasing complexity of buildings, such as occlusions and specular surfaces.

This research aims to address these challenges by developing a 2D-3D joint modelling and enrichment approach for as-built BIM based on the integration of laser-scanning and photogrammetric point cloud data. It aims to combine the advantages of both methods to generate a complete and accurate BIM model, and finally update this model according to the actual property states. This research mainly consists of the following four interconnected phases:

  1. Laser-scanning point cloud modelling
  2. Photogrammetry-based modelling
  3. Integration and registration for complete BIM model
  4. BIM model updating and enrichment

This PhD project will be one of six projects being pursued in a cross-disciplinary mini-College of Doctoral Training (CDT) running at Loughborough University from 2022 to 2026. This mini-CDT is part financed and supported by the WTW Research Network, the award-winning collaboration between academia, finance and research industries on the understanding and quantification of risk.

This industry collaboration builds on the earlier partnership between Loughborough University and WTW in the recently completed TECHNGI research project on technology and next-generation insurance services. A full description of the mini-CDT, of the individual PhD projects and of the support provided by the WTW Research Network can be found on TECHNGI website.
