DESCRIPTION
Speaker: Chris Brown, HOK -Design creation and coordination 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

BIM process for Building Smart and Sustainable Design at HOK
BIM BAM BOOM!

HOK Building Smart Strategy "Buildings cost much more than they should and perform much less efficiently than needed….. the real promise of BIM extends from design to construction and building operations."

HOK Building Smart Strategy

Refined Concept: Lives of a BIM Model 1. Conceptual Design Model :
feasibility, environmental assessment, presentation
2. Design Intent Model: coordination and scheduling through construction docs
3. Design Fabrication Model: clash detection through finished construction, phasing, quantities
4. As-Built Model : for building occupation maintenance, operations and facilities management
Currently consultants have taken it upon themselves define and deliver all of these models

Conceptual Design BIM Model Essential
1. Conceptual Design Model : feasibility, environmental assessment, presentation
2. Environmental Design Model : MEP standards, environmental assessment
6
Conceptual Design BIM Model Essential
1. Master plan or urban design : feasibility, environmental assessment, presentation
2. Environmental Design Model : MEP standards, environmental assessment

Contractor to Set Standards 2. Design Intent Model(BAM):
-coordination and scheduling through construction docs -consultant led including the whole team
3. Design Fabrication Model(BAM):
-clash detection through finished construction, phasing, quantities -contractor led
8
Owner to Set Standards
4. As-Built Model(BOOM): for building occupant maintenance and future development BIM : Building Information Model Design cost impact
BAM : Building Assembly Model Construction cost impact 10 times design cost
BOOM : Building Owner Operational Model
Maintenance impact 30 times design impact over building life

BIM Analysis Tools Earlier in the Design
Analysis Opportunities: pushed to the front of BIM curve where the Cost of a design change is minimal.

BIM Analysis Tools Earlier in the Design
Analysis Opportunities: pushed to the front of BIM curve where the Ability to impact performance is maximum.
