BIM (Building Information Modelling) Objectives

  • Increase quality of co-ordinated design information, eliminating design conflicts prior to construction
  • Increase collaboration between design disciplines

BIM Scope

  • 3D virtual model all MEP services
  • 3D virtual model the structure as no model was supplied by the structural engineers
  • 3D virtual model all fire protection (sprinkler systems) as the fire protection contractor could not produce 3D models
  • 3D virtual model all certified / procured plant and equipment
  • 3D virtual model all bracketry for back of house corridors
  • 3D virtual model all anchor and expansion devices
  • 3D virtual model all access zones to demonstrate access to all maintainable plant, equipment and access points, such as rodding eyes
  • Co-ordinate and clash detect all MEP services with structure and all other trade contractors
  • Produce 2D installation quality drawings for all MEP services, fully notated and dimensioned in x, y & z planes
  • Manage the EDMS (Electronic Data Management System) for the uploading and downloading of models, drawings, technical submittals and RFI’s (request for information)
  • Producing progress reports and attending / chairing bi-weekly BIM review meetings


The BIM process for the delivery of a clash free MEP model and installation detail drawings took 10 months for a 4-man team. Bi-weekly meetings held at Sisk site offices assisted with a collaborative BIM process with the input of the design team and all sub-contractors. The upfront BIM process enabled accurate builderswork details to be produced and built into the construction phase ensuring no costly rework. The installation of the MEP services ran very smoothly with very positive feedback from the sub-contractors and Sisk.

BIM Tech was appointed on this project by Sisk after the success of the Hilton hotel Wembley project that was also completed for Sisk in 2012.
