  3. 3. DUBAI DECREES BIM – WHY? • Improve project delivery in terms of quality • Enhance coordination and collaboration between stakeholders throughout the project life-cycle • Reduce time and cost • Standardize requirements and specs • Facilitate generation of BOQs • Improve pricing accuracy Ref: Circular 196/2014, 207/2015

  7. 7. DEFINITIONS: BIM ▪ BIM is often misunderstood and the focus has mainly been on the 3D models and multi-discipline coordination of design information. ▪ The "I" in BIM is the real benefit but in the same time the biggest challenge. ▪ CCC has used 3D/BIM based tools and linkages to build up its new Integrated Project Control System. ▪ Below is the summary of methodology that helped us achieve our objectives.
  8. 8. BIM AUTHORING – CCC APPROACH ▪ Established Centers of excellent in Dubai, Cairo, Ramallah and Athens ▪ Developed BIM authoring standards to meet contractor requirements ▪ StandardWBS: Object Level and progress steps level ▪ Standardized Object Naming Convention ▪ Developed best practices for scope definition through standardized BOQs ▪ Comprehensive EDI with clients, A/E’s and Subcontractors ▪ Develop and promote best practice for change management
  9. 9. PROJECT DATA SETUP ▪ Linking with Estimation ▪ Quantify resource requirements per object: Labor, material and equipment ▪ Linking with Planning ▪ Determine when resources are needed and when ▪ Constructability review (4D) ▪ Linking to Document Management : ▪ Engineering status ▪ Required drawings & Specifications per work package. ▪ Linking with Materials Management ▪ Assure availability of material when needed ▪ Maintain traceability of utilized material
  10. 10. PROJECT DATA SETUP ▪ Linking with Quality System ▪ Quantify testing scope, ▪ Assure quality and fast delivery of project ▪ Manage punchlists. ▪ Verify progress ▪ Establish interfaces between trades ▪ Linking with O&M System (WIP) ▪ Help clients to identify requirements as early possible (LOD 500, IFC, COBie, ISO15926, etc.) ▪ Assure clients smooth data handover. ▪ Link with IoT devices
  11. 11.  Reliant Pull-DrivenTechnique optimize supply chain rather than sub optimization  Assure availability of resources before start of activity.  Emphasize productivity through the full work chain vs. individual activities  Prevent sub-optimization  Partnering  Proper ProjectWork Breakdown Structure  Project/Area/Sub-Area/Fragnet/Activity/Object/Operation  Integrated EPC schedule with Emphasis on Handover and Construction Activities. (effective supply chain)  3D model built withWBS in mind and used as primary scope management tool.  Early on Cooperation with the Partners/ EDI definition.  3 Month Look Ahead Schedule/ Material forward plan  3 weeks Look Ahead Schedule PROJECT CONTROL STRATEGY

  14. 14. PROJECT CONTROL SETUP - 3-MONTH CYCLE ▪ Define Work Front boundaries ▪ “Work Front” is the multi-disciplined project scope breakdown with a duration of 1 month. ▪ Inherit scope of work to complete the work front. ▪ Fragnet (with their disciplines) defined ▪ Inherit needed documents, material and crews needed to complete the work ▪ FEL document created ▪ Material Forward Planning
  15. 15. PROJECT EXECUTION AND CONTROLS ▪ Rate the readiness of work fronts based on Schedule, FEL and material availability ▪ Move to site and finalize fragnet operations (weekly planning cycle) ▪ War room ▪ Lean Board ▪ Assign fragnets to objects
  16. 16. PROJECT EXECUTION AND CONTROLS ▪ Issue work orders to crew foremen (and/or progress card) ▪ Daily coordination meetings ▪ Daily update of progress ▪ Collect site problems ▪ Collect actual timesheet data ▪ Control interface management ▪ Collect quality control forms and punch list ▪ Manage reporting cycles ▪ Weekly/Monthly progress report ▪ Earned value analysis ▪ System completion ▪ Subcontractor performance ▪ Billing and claim processing ▪ Etc.
  17. 17. LEAN CONSTRUCTION ▪ We needed to optimize site work processes. ▪ Lean construction is an adaption of Lean manufacturing and production principles which aims to improve the construction process primarily through minimizing waste and maximizing value (Bryde, 2012). ▪ Lean construction subdivides the work into collection of typical workflows by different crews. ▪ Concentration is on a smooth transfer of work between disciplines and the continuous work for all crews (line of balance, simulator) ▪ Concentration is on preventing sub-optimization ▪ Lean methodology transfers the detailed planning to the site foremen through collaborative weekly meetings. ▪ Lean transfers ownership of detailed planning to site staff. ▪ This greatly enhances the confidence in weekly planning.
  18. 18. BIM-AWP - LEAN The AWP Effect NegativeImpact Dependence on other discipline and activities. Lean Effect Laminar flow of Work Minimize idle time Optimize crew usage Minimize Buffers
  19. 19. IN CONCLUSION ▪ It is a journey to leverage BIM, but it is not hard (Sunway case) ▪ Commitment from top management and buy-in by all players is a must ▪ CCC built it’s own hybrid solution based on international best practices ▪ Open issues: ▪ Owners leadership & role ▪ O&M handover requirements from construction ▪ Imposition vs integration of software tools FINAL WORDS: TO SUCCEED YOU NEED COLLABORATION, STRUCTURED DATA AND PLANNING

  23. 23. OBJECT NAMING CONVENTION To make a more effective use of the BIM in construction, the idea of Object based BIM was introduced. A unified automated coding system was developed for the different disciplines (Structural / Architectural / MEP). We define an object as “The reasonably smallest portion of a building that reflects the logic of construction, facilitates the transfer of work between the different crews and can be reported in progress or QS (Quantity Surveying) reports”. For example a column, a beam, a room finish, a diffuser, a fan, an electric socket…etc) WS-03-CL-D-010-D-010
