3 BIM - The Skanska Global Definition Building Information Modelling is a method to describe a project 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 got the right project information at the right time. 3

4 What Does That Mean in Practice? BIM Project - A designated project where all participants agree to a common set of standards and processes. The data created enriches across the life of the project and can be used to benefit all members of the team. This applies during design, construction, operation and ownership - it all starts at Pre-Construction. BIM is a way of working, not something you can procure. 3D Model - A BIM based deliverable, but not BIM itself. Attributes - Fields within objects that are used to host, link or reference information, the I in BIM. This intelligence is used to support the work of the project team across all phases. 4

5 BIM - It is good but BIM it s not a magic pill 5

12 Safety in Design BIM can facilitate better and more regular safety reviews during design 12

13 The Virtual Prototype Enabling Industrialisation BIM data allows Skanska to develop a virtual prototype, the model is checked for safety, environmental credentials, buildability and spatial coordination. During production staff enjoy a environment that is safe and warm with waste recycled back into the production process. Fewer staff are on the construction site and for less time. 13

14 Safety on Site Reviewing planned work with a model adds a new dimension! Sample 2D services drawing, hard to read and understand. The potential for error is high re-working takes time and cost, risks not easily understood. 14 Coordinated BIM model, easy to review and understand. Clash free design can be easily achieved reduced site work and safer.

15 Safety Coordination and BIM The barrier is designed to leave sufficient room for safe working during wall construction. The team understand what a safe environment must look like. The barrier can remain in place during construction, safer by design. BIM can facilitate improved project safety reviews and staff engagement in safety planning. 15

16 The Building Blocks of Site BIM Designers and contractors working together Skanska has produced a library of construction components, allowing projects to create a virtual site environment. Safety inductions become highly tailored to suit upcoming work, improving site staff understanding and helping them become aware of the risks. 16

17 Laser Scanning Bringing the construction site to the desktop 17

18 BIM and the Construction Site We need more data to exploit Tablets PC s on site Synchronised with the project dataset Construction BIM toolbox Some projects have over 50 tablets in daily use Internally developed BIM tools 18

20 BIM to Facilitate Timely Optioneering Enabling More Sustainable Design 20

21 Example Green BIM Tools Concept design Detailed design 3D Object design Conceptual design optimisation of energy performance Solar Coordination Consolidation Communication Cloud computing environmental analysis engine Optimised whole building energy consumption Scheduling Shading Design Management Optimised carbon content 2D Drawings Thermal Clash prevention Optioneering for renewable energy And more Acoustic and more 4D and more And more 21

22 Conceptual Design Optioneering Option 1 Option 2 22

23 Results from a Skanska BIM Study Return on Investment Margin - up Accidents - down 53% Waste - down 49% Client satisfaction up The results were formed by comparing BIM with non BIM projects 23

25 BIM - When is the Right Time to Invest? UK Impossible President UK Impractical President UK President Possible UK President Expected UK President Required Time Impossible - A vision Impractical - Too expensive / time consuming, monitor and prepare (1) Possible - Achievable, act now! (2) Expected - Advantage eroded becoming the norm (3) Required - Industry standard skills required but no advantage (3) 25

28 Recommendations Develop platform neutral librarys Share more data in native formats Connect with downstream users of the data Agree priority codes to be embedded in objects Research database links for balance of codes or data needs Share all product information over the web Engage early with projects - optioneering phase BIM is a new way of working, not a replacement for 2D CAD 28
