Lifecycle Management with Digital Design and Construction Information
• BIM is a change in mind-set towards information
• BIM is a set of processes, tools and approaches to provide greater visibility, reduce project risk and information loss
• BIM should be considered as a holistic approach that builds upon the existing management systems
• BIM is an approach which supports the broader data management and asset management
What we need to know about BIM
Case Studies
Means of Egress
Basement 2 Mezzanine GA Basement 1 Framing Plan
Means of Egress
• De-risking Project documentation
• Visualising Interfaces
• Promote team collaboration
• Ability to created unlimited sections
• Review advanced sequencing works
• Identifying and resolving issues early
“If this issue had not been
discovered early, this would
have had a major structural
implication requiring redesign
and abortive works with
programme implications and
statutory authority approval.”
Terry Martin – Senior Construction
Manager

• Visualising the design
• Planning utilities routing with works
• Engaging stakeholders
• Quicker design updates
• Generate shop drawings
Temporary Works Design
• Demonstrate project programme
• Validating programme change
• Highlight programme conflicts
• Identifying missing information
• Coordinating contract interfaces
• Temporary works info critical
4D Programme Review
Reviewing construction
sequencing. Aligning model
with project programme.
“4D has been used to demonstrate
the practicality of the proposed
DRM, highlighting key interface
issues.”

• Extracted Quantities
• Review Over/under excavation
• Material procurement
• Planning and sequencing works
• JIT delivery
• minimise waste
• Validating subcontractors execution of works
Surveys and Quantities
1. Import Survey Points
2. Generate as-build surface
3. Overlay with design model
“Using the model to model
complex geometry and
analyse quantities has
helped to save resources
and time.”
Chan Kit Lam – Construction Manager
Enabling Works
• Spatial Coordination
• Combined Interfaces
• Highlighting limited space
• Advanced planning
• De-risking the abortive works
Services Coordination
Services coordination was
carried out without
considering cladding
interface
“Using the model to identify
coordination issues has
helped to build the
awareness of the buildings
complex geometry.”
Terry Martin – Senior Construction
Manager
• Generate fabrication data
• Facilitated coordination with installers
• Develop workable solution for gulley's
• Aided site setting out
Complex Skylight Geometry• Quick response to site
conditions
• Working with fabrication
constraints
• Tight schedule
• Complex geometry
“The façade contractor found the BIM model indispensable to the task of redesigning the system and details, validating the details throughout the structure, and extracting information for fabrication and setting out.”
• Test Design Options
• Optimise decision making
• Minimise waste
• 2D extracted from the 3D models
• Enabled clash analysis
• Complex system coordination
• Maintained models for as-built
• Improved workflows
• Developed internal capability
Leveraging BIM Data“Having full control of the
CSD coordination has allows
us to control the design and
harness the value of BIM.”
Nehemiah Otivar – CAD & BIM Team
Leader, Shinryo

Construction Information
• Signage Review
• Project Visualisation
• Stakeholder engagement
• Design Review
• Identify conflicts
• Consolidate Comments
Station Wayfinding and Design Review
• Enhance methodology understanding
• Identified site constraints and risks
• Share with stakeholders
• Used for Health & Safety briefing
Risk Assessment and Method Statements
Models used to support the
Engineers in the preparation of
method statements. 3D Images
were inserted into standard
method statements and helped
to visualise the sequence of
works.
