1st qatar bim user day business processes supported by bim methodology, part 3
DESCRIPTION
Speaker: Nashwan Dawood, Teesside University -Scheduling and progress monitoring -Joint open discussions, Q&A 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. More information: www.bimuserday.com Follow BUD on Twitter @bimuserdayTRANSCRIPT

Scheduling and Monitoring Processes
• Scheduling: what, when, by whom, how, what-if, etc
• WBS is the standard for scheduling practices. Network analysis, bar-chat 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.

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.

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.

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 work-face.
• New paradigm for utilising BIM for scheduling has been presented.
