Speaker: Gunnar Godawa – Hochtief ViCon -Scheduling at the Nile Corniche Project 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 @bimuserday

9. 2. Applied Use-cases
Verification of the Construction Program – Success factors
•
Ensure quality of 4D model by checking
that all activities are linked to the model
•
Visualize the construction sequence to
allow additional schedule analysis
•
Include automated verification of the
resource distribution over time
•
Create reports to document the results
of the program verification

11. 2. Applied Use-cases
Usage of a 4D Model for Progress Monitoring – Success factors
•
Define a database structure to ensure data integrity
•
Enable the team to access the project schedule
without expert software
•
Implement regular progress updates in the project
database
•
Integrate the provided information in regular project
tasks such as progress reporting
•
Visualize the construction progress for better
evaluation and common understanding
