Building Information Modelling
BIM at Skanska
BIM – The Skanska AB Definition:
Building Information Modelling is a method to describe the building and its spaces, structures, components and materials with their essential information and properties. The model is a container for the information.
BIM can also be described as a collaborative approach making sure the right people get the right project information at the right time.
“From January 1st 2009 all new Design and Build projects where design has not yet started – shall adopt Building Information Modelling”

Comments/requirements
• Accurate and visual design, no shortcuts (completed design in all details)
• Standardized components in use, libraries and catalogs
• Information on materials and components available from model to meet O&M/FM & Investor’s needs
• Required under Skanska
Group BIM Strategy
• Must support requirements of
the BIM applications detailed
below
• CJV to determine optimum
technical solutions
• Must agree and adopt an
object/asset coding system
Intelligent
3D-Modelling
Confidential14
object/asset coding system
at the commencement of
design to be used throughout
the life of the project
• Analyze alternative design/construction/maintenance options
• Select options on basis of optimized capital and ownership costs
• Ensures most attractive / affordable whole life cost solution
• Accurate life cycle cost estimation
• Reduced risk in life cycle fund management
• Required under ID BIM
Strategy
• BIM to facilitate rapid re-
assessment of implications
and quantities of design
options
• Suggested that a member of
the BIM team should attend
all optioneering workshops in
order to facilitate BIM
support

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
16
− 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 time
Utilisation of BIM at NKS
− Beneficial way of working throughout the project, facilitating a safer, greener,
faster, leaner project deliveryIdentify specific search setsVisualisations Tracking RDD Process
After ReviewImproving the design
Clash PreventionSafety Reviews
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
18
• 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 at10 to 1
Benefits to Designers
− Able to visualise road layouts
− Checking the visibility positioning of signs and signals
− Positioning gantries efficiently
− Clash prevention of infrastructure− Clash prevention of infrastructure
− Assists with third party engagement and understanding
− Buildability verification and construction sequences confirmed
− Reduction of environmental impacts

BIM on the A1 in Poland
3D survey and control system supported by GPS
23
• Haul road on Phase 2 of the A1 in Poland was modelled and saved circa £3.5m in accurate location and construction
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 − 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 models
21
Interactive touch screen 1:50 process
− BIM Design− Captures the information from the 3D planning, review and adjustment of spaces
22
3D Room Elevations
− BIM Design− Captures the details of the 3D elevations including equipment requirements
23
Virtual Samples/Mock-ups
− BIM Design− Data collected allows for virtual mock-ups to be built and tested

What is OPEN BIM?OPEN BIM is a universal approach to the collaborative design, realisation and operation of buildings based on open standards and
workflows. OPEN BIM is an initiative of buildingSMART International (bSI) and several leading software vendors using the open
buildingSMART 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 in
transparent 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 and
consequential 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 into
the BIM.
