About the Qatar BIM User Day:

Qatar University, HOCHTIEF ViCon and Teesside University proudly take the initiative to facilitate modern and innovative methods in the Gulf construction industry. The focus is Building Information Modeling (BIM), and our aim is to establish a knowledge platform with government, research and industry experts. The User Day aims to help people to share knowledge, discuss new technologies, and identify new potentials for BIM.

Transcript

  • 1. 2nd Qatar BIM User Day “Technology is the key to success” BIM for Project Scheduling and Quantity Take-Off Dr. Racha Chahrour HOCHTIEF ViCon Qatar W.L.L. www.hochtief-vicon.com Dr. Racha Chahrour HOCHTIEF ViCon 1
  • 2. Agenda 1. 4D Model Creation Strategy 2. 4D Scheduling Software 3. Quantity Take Off 4. Summary Dr. Racha Chahrour HOCHTIEF ViCon 2
  • 3. 4D Model Creation Strategy Major Elements 3D Model 4D Model Schedule Dr. Racha Chahrour HOCHTIEF ViCon 3
  • 4. 4D Scheduling Software Import Available Software Systems Program 3D Model Create 4D 4D Editors Dr. Racha Chahrour HOCHTIEF ViCon 4
  • 5. 4D Scheduling Software Manual Linking in NavisWorks Structured 3D Selection Sets Schedule activities Links Dr. Racha Chahrour HOCHTIEF ViCon 5
  • 6. 4D Scheduling Software Rule-based Linking in NavisWorks Parameter based search sets Parameter Linking rules Dr. Racha Chahrour HOCHTIEF ViCon 6
  • 7. 4D Scheduling Software Manual and Rule-based Linking in Synchro Attributes 3D objects Linking rules Attribute scheduling tasks Dr. Racha Chahrour HOCHTIEF ViCon 7
  • 8. 4D Scheduling Software State of the Art Functionalities of 4D Editors • Import various 3D model formats • Support major scheduling software • Construction sequence animation • Synchronisation of model and program data • Rule-based activity linking Visual Schedule Analysis Dr. Racha Chahrour HOCHTIEF ViCon 8
  • 9. 4D Scheduling Software Limitations of 4D Editors • Limited export of created 4D model • Complex and time consuming linking process • Focus on visual schedule analysis • High efforts for 4D model updates No Scheduling Support Dr. Racha Chahrour HOCHTIEF ViCon 9
  • 10. Quantity Take Off Model-based Quantities - Creation Strategy / Software Specs 3D Model Filled BOQ with modelbased Quantities Dr. Racha Chahrour HOCHTIEF ViCon 10
  • 11. Quantity Take Off Structural Elements • Elements: • Columns • Walls • Ceilings • Beams • Quantities with the corresponding structural elements Dr. Racha Chahrour HOCHTIEF ViCon 11
  • 12. Quantity Take Off Rules of Measurements • All openings like doors, windows, ceiling fretworks are subtracted -according to the QRM- of the corresponding structural elements • If wall and beams intersect, the intersection area is subtracted of the wall Dr. Racha Chahrour HOCHTIEF ViCon 12
  • 13. Quantity Take Off Visualisation of Object Attributes • Walls, columns and ceilings may have different qualities. e.g. walls: a. Drywalls b. Blockwork c. Concrete a. c. b. • So different types of walls are displayed in different colours Dr. Racha Chahrour HOCHTIEF ViCon 13
  • 14. Quantity Take Off Finishing Works • Finishing works can be calculated over the rooms • A room is bounded by vertical and horizontal structural elements Dr. Racha Chahrour HOCHTIEF ViCon 14
  • 15. Quantity Take Off Process Requirements • Full definition of model requirements at project start to ensure re-usage of 3D models • Definition of the model structure considering construction joints • Usage of appropriate agreed/standarised description for 3D model elements • Implementation of rules of measurement to consider small openings • Easy access to created data for all stakeholders Dr. Racha Chahrour HOCHTIEF ViCon 15
  • 16. Summary • Latest technology is generally able to meet common project requirements • Rule-based schedule linking would improve performance • Visualising the construction program improves project communication among all stakeholders • Data exchange is limited • Quantity take off requires accurate, structured and qualified 3D models Dr. Racha Chahrour HOCHTIEF ViCon 16
  • 17. Thank you for your attention! Dr. Racha Chahrour BIM Manager HOCHTIEF ViCon Qatar W.L.L. www.hochtief-vicon.com Dr. Racha Chahrour HOCHTIEF ViCon 17
