          Sharing of geotechnical data for
        
        
          use in Building Information Model-
        
        
          ling should result in more informed
        
        
          decision-making, improved collabora-
        
        
          tion and emphasise the importance of
        
        
          geotechnics.
        
        
          It has been well-documented that
        
        
          Building Information Modelling
        
        
          (BIM) enables better decision making
        
        
          during the planning and design stages
        
        
          of a project, throughout the construc-
        
        
          tion process and into the operational
        
        
          and maintenance phases.
        
        
          However models sometimes appear
        
        
          to neglect geotechnical aspects. BIM
        
        
          often appears to start from the ground
        
        
          up, with the subsurface considered
        
        
          as an homogenous substance. This
        
        
          implies there is no risk in the ground,
        
        
          which is clearly untrue.
        
        
          In fact, there is a host of benefits to
        
        
          applying BIM principles to geotechni-
        
        
          cal data management and including
        
        
          geotechnical data in BIM: it allows
        
        
          considered design optioneering and
        
        
          refinement at the outset of a proj-
        
        
          ect; minimises geotechnical risk in
        
        
          construction and enables cost-effective
        
        
          repairs and maintenance of assets
        
        
          throughout the project’s lifetime.
        
        
          Using BIM means geotechnical
        
        
          contractors and consultants can col-
        
        
          laborate easily. Data sharing and
        
        
          central data management results in
        
        
          big improvements in efficiency and
        
        
          quality.
        
        
          
            Incorporating geotechnical data in BIM aids design
          
        
        
          
            optioneering and refinement at the outset of a project.
          
        
        
          
            Geotechnical modelling in BIM can lead to a more complete understanding
          
        
        
          
            of project elements.
