Implementation of geotechnical data to Building Information Modelling (BIM) can improve the master planning of building development and facilitate monitoring of site construction. At the early stage of design development, application of BIM embedding the site geology, building master layout and associated engineering design elements (i.e., foundations and ELS works, etc.) helps the illustration of different options of building massing, especially for a development with significant geotechnical content (i.e., hillside site, near MTRC tunnel). It can be studied quickly to come up with the most cost-efficient scheme of building plan and information including a balance of optimum choice of volume of soil/rock excavation, extent of formation works, amount of material input, etc. BIM can also help engineers to review the construction sequence for complex geotechnical work including phasing of different kinds of works such as pile foundation construction, site formation and ELS works. Nowadays, creation of the 4D (and 5D) modelling allows the programme to be optimized (and construction cost forecast) and facilitates better understanding of the construction sequence. Simulation for construction method in geotechnical works is developed to allow the construction method to be rehearsed virtually so that the engineers and workers can understand it more before execution. This paper discusses the aforesaid BIM applications in geotechnical works for different building projects including institutional developments. The use of BIM results in better design communication within the design team, as well as with the owners and other stakeholders.
