  • 1. 1Christoph H. Weber BIM specific aspects in current contracts
  • 2. 2Christoph H. Weber AGENDA • Introduction • Important aspects: Overview • Focus Aspects – Responsibilities and Roles – Scope Definition – Specification Documents • Conclusion
  • 3. 3Christoph H. Weber How we know contracts in Qatar Direct or indirect engagements with…
  • 4. 4Christoph H. Weber AGENDA • Introduction • Important aspects: Overview • Focus Aspects – Responsibilities and Roles – Scope Definition – Specification Documents • Conclusion
  • 5. 5Christoph H. Weber BIM spans all project phases Increase productivity over the lifecycle 3D Marketing Model 3D Design Model 3D Fabrication Model 3D Asset Model 3D Schematic Model 3D Quantity Model • Remember purpose and potential of BIM: Increased productivity throughout the lifecycle of a construction. Reduce costs and risks by enabling new ways of collaboration and communication. Help manage complexity. • Consequence for Contracts: Keep it simple, don’t overspecify, ensure BIM organization spans all phases!
  • 6. 6Christoph H. Weber BIM in Contracts Some Important Aspects • Procurement policy (type of contract) • Roles and responsibilities re BIM • Allocation of risks • Ownership of the BIM model / IP rights • Standard of care / purpose of the model • Data exchange and model management • Scope definition • Specification Documents • …
  • 7. 7Christoph H. Weber AGENDA • Introduction • Important aspects: Overview • Focus Aspects – Responsibilities and Roles – Scope Definition – Specification Documents • Conclusion
  • 8. 8Christoph H. Weber BIM Roles and Responsibilities in Contracts • Increasing awareness of BIM Roles • Differing definitions of designations (BIM Champion, BIM Leader, BIM Manager, BIM Coordinator, …) • Unfortunately still tendency to see BIM Manager as “the new designation for our Design Managers”
  • 9. 9Christoph H. Weber Example: BIM personnel roles „The Contractor shall provide personnel that will perform the BIM Services on the Project. No 1 BIM Coordinator  10 years experience  BIM Implementation track record in multiple companies  Proven track record of establishing BIM Standards  …“ Is this a „Coordinator“ or a „BIM Manager“? Definitions vary… There is probably 10 people in MENA with this profile. 7 of them sit in the audience. None of them is free for another project.
  • 10. 10Christoph H. Weber IT Support BIM in the project organization Architect MEP Engineer Others Structural Des. Client BIM Advisor Main Contractor Facility Manager Steel Fabricator MEP Subcontra. Suppliers All these „stars“ may call themselves BIM Manager. All work on BIM. Who is high enough in the org chart to coordinate their work?
  • 11. 11Christoph H. Weber AGENDA • Introduction • Important aspects: Overview • Focus Aspects – Responsibilities and Roles – Scope Definition – Specification Documents • Conclusion
  • 12. 12Christoph H. Weber Scope Definition in current contracts • Increasingly specific requirements in contracts • 5 out of 5 recent drafts list BIM uses, deliverables • Often very broad scope even for small projects
  • 13. 13Christoph H. Weber Example: BIM use definition „The Model shall be developed to LOD 500. During the Project, it shall be shared with the Client and used for  Design review and approvals  Virtual walkthrough  Clash mitigation  Building trade coordination  Cost estimation  …“ This is good! Better would be a definition (or reference to a guideline) specifying what exactly e. g. a virtaul walkthrough is – or what you want to achieve with it.
  • 14. 14Christoph H. Weber Example: BIM capabilities definition „The Models shall have the capabilities:  3D Models: use in clash detection between buildings and trades  4D Models Use in Construction Scheduling, Site Logistics, Phasing, Constructability Review and Sequencing  …“ Capabilities definition – even better: What is supposed to be done with the model.
  • 15. 15Christoph H. Weber LOD • 4 out of 5 contracts require „LODs“ for models • „Level of Detail“ vs. „Level of Development“ • Often unnecessarily general requirements • „All model elements shall be maintained at a Level of Detail 400 throughout…“ LOD is defined differently – over 40 standards! Reference the standard, be precise and don‘t rely too heavily on LOD as a spec. You do NOT want (to pay!) „all“ model elements down to the doorknob at the same level of detail!
  • 16. 16Christoph H. Weber AGENDA • Introduction • Important aspects: Overview • Focus Aspects – Responsibilities and Roles – Scope Definition – Specification Documents • Conclusion
  • 17. 17Christoph H. Weber BIM Specification Documents • BIM Implementation Plan • BIM Protocol • BIM Execution Plan • Modeling Guidelines • Model Element Authoring Matrix • …
  • 18. 18Christoph H. Weber AGENDA • Introduction • Important aspects: Overview • Focus – Responsibilities and Roles – Scope Definition – Specification Documents • Conclusion
  • 19. 19Christoph H. Weber Three things to remember when drafting a contract • Never forget: BIM is to improve productivity. Transparency and detail are not ends in themselves. • Install a „BIM Leader“ in the project organization and facilitate integrated teams if possible • Be as specific as you can. Provide samples and adapt specification documents to your needs
