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

Means of Egress

1.30m

• 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.
