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.

7. 2. Applied Use-cases
Quantification from the 3D Model – Success factors
•
Modeling Guidelines to ensure the reusage of the model in the project lifecycle
•
The 3D model is developed according
to the project WBS
•
Additional attributes in the 4D model
support the easy link with the schedule
•
Specs
POMI
3D Model
and QTO
Split of 3D geometry and numerical
data enable the flexibility to reuse data
in various software tools

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

14. Valuable Project Experiences
Proven Team Benefits - Survey
•
Always current data available
through remote access to the
information
•
4D/ 5D Model is continuously used
for reporting purposes
•
Database with life-cycle approach
will support later operation phase
•
Easy user interface supports the
usage of BIM data
