Project Title: Smart Construction Platform based on Cloud BIM and Image Processing
Hosting Institution: The Hong Kong Polytechnic University (PolyU)
Abstract: Building Information Modeling (BIM) is the trend in the construction industry due to its advantages in visualization and analysis in contrast with the traditional CAD. However, its current use is largely focused on design coordination and performance evaluation. Among the industry recognized applications is the use of 4D (3D + time as the 4th dimension) BIM models in simulating construction master plans, which cannot be directly used to guide construction activities.
In the previous ITF project (ITP/036/12LP), the project team has demonstrated that BIM models can be transformed into interactive tools for construction safety monitoring. With the initial success, we propose to further research and develop enabling technologies to systematically extract and transform BIM objects into a construction management platform according to construction plans. Specifically, this project aims to develop a BIM-based task decomposition and assignment technology to make BIM information and work instructions be reached directly by workers, a means of information indexing and retrieval enabling workers’ convenient and timely access to information relevant to their work, and an image processing tool for automatic progress estimation according to BIM models and site photos.
This study will contribute to the in-depth use of BIM in construction by providing a progress visualization platform, so that project stakeholders (including the public) can keep abreast of the progress of a project. The technologies to be developed will also mitigate project delays and improve productivity of the industry.
Multiple organizations, including Construction Industry Council (CIC), Chun Wo Building Construction, Able Engineering, China State Construction, etc., have all expressed significant interests in conducting trials for the aforementioned technology. We believe that there is a large demand for this technology and the results of the project will have a large impact to the construction industry.
