  • 3. BIM at SkanskaBuilding Information ModellingBIM – The Skanska AB Definition:Building Information Modelling is a method to describethe building and its spaces, structures, components andmaterials with their essential information and properties.The model is a container for the information.BIM can also be described as a collaborative approachmaking sure the right people get the right projectinformation at the right time.“From January 1st 2009 all new Design and Buildprojects where design has not yet started – shall adoptBuilding Information Modelling”

  • 16. Benefits on Accommodation projects− On the Barts Hospital(383 beds) project the M&E package cost was avoided average scope increase of circa £1.7m by improved design co-ordination and clash prevention− Use of Tablet PC’s at the Royal London Hospital (905 beds)reduced the management time in office to site and back by circa 50%− Efficient take-off of quantities from the model saved £350,000 in QS time16
  • 17. Utilisation of BIM at NKS − Beneficial way of working throughout the project, facilitating a safer, greener, faster, leaner project deliveryVisualisations Identify specific search sets Tracking RDD ProcessImproving the design After Review Safety Reviews Clash Prevention
  • 18. Benefits on Highways• On M25 model illustrated where batter could replace proposed piling and saved £3.0m• GPS machine control via the model eliminated profile so saved 3 engineers for the duration of the project• Laser scanning of existing bridges provided a complete and retrievable database of information including dimensions in a safe manner. Saved £1000 per day in traffic management• Improved engagement/understanding with the emergency services, fire police etc. on M25• Efficient and accurate schedules production of drainage, barriers lighting etc. on M25 75% more efficient• Design is optimised by active modelling. Sign Location Gantries reduced from 46 to 35 on M25 saving £3.5m− The Return on Investment in BIM processes at the M25 is calculated at 10 to 1 18
  • 19. Benefits to Designers− Able to visualise road layouts− Checking the visibility positioning of signs and signals− Positioning gantries efficiently− Clash prevention of infrastructure− Assists with third party engagement and understanding− Buildability verification and construction sequences confirmed− Reduction of environmental impacts19
  • 20. BIM on the A1 in Poland3D survey and control system supportedby GPS23 • Haul road on Phase 2 of the A1 in Poland was modelled and saved circa £3.5m in accurate location and construction
  • 21. Benefits during bids− Fewer Room Layout reviews: The 3D and the live updates generally got the rooms agreed in principle in a single meeting ( previously 3 to 4 meeting required !)− The client asked us to do about 50 rooms we achieved 130 including equipment and this gave confidence to the 1:200 area schedules. Modelling made this easy− Touch screens were really liked by those who used them. Others preferred the architect to update and watch the items move on screen and direct.− A significant difference was the loading 3-D as the client understood better and the live updates ensured all their directions were tested then, rather than taking them away and finding it did not work.− Able to market test 26 works packages (90%) of project because of meaningful images of project illustrating the project and reducing risk.− Facilitated submission requirements− Permitted earlier design decisions e.g. Façade with thermal modelling based on architectural and frame models21
  • 22. Interactive touch screen 1:50 process− BIM Design − Captures the information from the 3D planning, review and adjustment of spaces 22
  • 23. 3D Room Elevations− BIM Design − Captures the details of the 3D elevations including equipment requirements 23
  • 24. Virtual Samples/Mock-ups − BIM Design − Data collected allows for virtual mock-ups to be built and tested24

  • 27. OpenBIM and Skanska: (Imported Slide)What is OPEN BIM?OPEN BIM is a universal approach to the collaborative design, realisation and operation of buildings based on open standards andworkflows. OPEN BIM is an initiative of buildingSMART International (bSI) and several leading software vendors using the openbuildingSMART Data Model.Why is it important?•OPEN BIM supports a transparent, open workflow, allowing project members to participate regardless of the software tools they use.•OPEN BIM creates a common language for widely referenced processes, allowing industry and government to procure projects intransparent commercial engagement, comparable service evaluation and assured data quality.•OPEN BIM provides enduring project data for use throughout the asset life-cycle, avoiding multiple input of the same data andconsequential errors.•OPEN BIM enables small and large (platform) software vendors to participate and compete on system independent, ‘best of breed’solutions.•OPEN BIM energises the on-line product supply side with more exact user demand searches and delivers the product data directly intothe BIM.Skanska• supports these principles• remains platform neutral• embraces BIM in its broadest context SmartBIM Solutions
