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.

1st Qatar BIM User Day Business processes supported by BIM methodology, part 3

  1. 1. Business processes supported by BIM Methodology: scheduling and progress monitoring Prof. Nashwan Dawood Teesside University, UK n.n.dawood@tees.ac.uk Speaker Name 1
  2. 2. Scheduling and Monitoring Processes • Scheduling: what, when, by whom, how, what-if, etc • WBS is the standard for scheduling practices. Network analysis, barchat and LoB are typical techniques • To update schedules, monitoring of construction activities will be conducted on weekly or monthly intervals. • New paradigm of integrating WBS with PBS for 4D planning. Whole schedule 2
  3. 3. Scheduling Systems 3
  4. 4. Issues with traditional scheduling Site congestions Crowded areas CAD Design Drawings Project Schedule Design Plan/Tender Access blockage Build 4 4
  5. 5. Concept of 4D Scheduling • Integration of BIM (mainly 3D models) and schedules (4D) • Shows progress of construction activities at any time. • Visualisation of construction products through time. • Site Logistics. 5 5
  6. 6. 4D and construction processes • • • • • • • • Initiation Preliminary Design and developments Detailed design Contracts and planning Production Commissioning Operation 4D scheduling Sequence of tasks 6
  7. 7. Integration processes Process BIM Schedule 3D models Integration of 3D And schedule 4D software 7
  8. 8. BIM & 4D Scheduling • Schedule analysis (constructability, spatial constraints, complex sequences, what-if) • Schedule Review (planned vs actual) • Communication and marketing (main contractor with client, main contractor with subcontractors) • Subcontractors coordination on site/work-flow planning • Track Construction progress. 8

  14. 14. Value of 4D planning  Analysis of 3 Major projects (combined value of £400 million)  Development of Measurement methodology for KPIs  Progress monitoring and data anlysis 94% Time 92% Safety 82% Communication 80% Cost 7% Planning Efficiency Client Satisfaction Team Performance 70% 65% 62% 60% Productivity 52% Quality 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% % 14
  15. 15. Value 15 15
  16. 16. Research projects in the coming 10 years: automated and flexible visual scheduling. BIM KB Rules about Work methods and temp activities Extension of BIM (ground models, 16
  17. 17. Conclusions • BIM has had very limited use in scheduling processes • 4D has been taken up with contracting organisation but as visual tool. • 4D has the potential to be developed to cover the control processes and utilised at workface. • New paradigm for utilising BIM for scheduling has been presented. 17
