Our BIM Vision
• To use BIM technology in a cost effective manner to assist to fill in gaps in project understanding in various ways .• Manage building information for projects• Enable a collaborative working environment
• Test and verify the coordinated design• Let the team and others understand the project content and process in real time
Chinachem has used BIM either directly or indirectly for various on over 9 projects. Implemented on the advice of Joe Wu of our Quality and Cost Control section, we have 4 major projects outsourced to BIM consultants at the moment. • Asian House, Hennessy Road new office
building.• 3 MacDonnell Road, luxury apartments.• University Heights, high quality apartments.
• TW5 Cityside, MTR project of 949 units and
commercial podium.
How we use BIM
It would be good if all consultants had BIM and the implementation and management could be through the lead architect. As our projects have been implemented quickly we were not able to determine if this could be done in a cost effective manner
As a result we use BIM consultants for the task. Currently we are using WSP on three projects and Construction Virtual Prototyping Ltd on another.
Asian House1 Hennessy Road
Consultants: Design Verification Asian House - “Neck” (LED) Options (Area)
Consultants: Design Presentation Asian House - True Dimension Photomontage
CALCULATIONS
Consultants: Design Presentation Asian House - Animation
Consultants: Design Presentation• Asian House - Visibility of Roof Top Signage from Kowloon
Consultants: Design Verification Asian House - Signage Options (Area)
Consultants: Design Coordination Asian House - Clashes at MOE Staircase
CAR PARK HEADROOM
Taking Off - Concrete Wall
UNIVERSITY HEIGHTS
UNIVERSITY HEIGHTS
TW5 Cityside. Mixed development of 949 units and commercial podium
Includes temporary relocation ofPTI, reprovisioning of aRCP, providing a temporary car park, diversion of seawater mains and the demolition of the existing multi story Car Park, PTI 5 footbridges and RCP.

Consultants: Design Verification TW5 - Existing Building Transport Complex Demolition
Consultants: Design Verification TW5 - Footbridge Demolition
• This animation is at least the 5th version• The 1st version was built from BD Submission (Structural)
Drawings but it was seen infeasible when the animation is shown• Issues were identified when watching each version and revisions
were made afterwards• If the exercise is NOT carried out, BD Submission (with an
infeasible scheme) can be made earlier but Approval is useless• Similar exercises in other projects have 8 revised Programme
and/or Methodologies in 2 weeks just because it is seen infeasible
Simulation - Demolition of Footbridge 1• This animation is at least the 5th version
• The 1st version from structural BD drawings before submission.
• Issues were identified when watching revised versions and changes made before submission
• If the exercise had not been carried out, the BD Submission could have been earlier, however a rejection may have happened, then after resubmission the time would have been longer.

BIM RISK REDUCTION
1.Reduce Risks• Time• Cost• Quality
2.Reduce Avoidable VOs• due to coordination issues
3.Enhance Efficiency for High Quality Building
• Efficiency in ‘Production’, Presentation and understanding of the design by decision makers
MAJOR BENEFITS• Visualization. Easier for all types of people which
helps understanding.• Verification. Design can be checked and before
tender is out, reducing risk of clashes, rework and variations.
• Measurement. Quick check of quantities can be used for cost planning and cross verification.
• Time management. Programmes and sequencing of works can be developed in 3D to test the logic and timeframes.
• Handover procedures can be improved.• Sales. BIM for input for the sales brochure
information for presale consent.
CHALLENGES. Lack of knowledge and understanding of the
usefulness of BIM. Input/output knowledge? Fear of the unknown! Why do we need BIM, the consultants will
coordinate the drawings? Why have a BIM consultant, give it to the lead
architect? Why spend money on BIM? Design changes.
SUGGESTIONS We need to have consultants input earlier to
avoid a reactive approach. We need to try to minimise changes, manage the input quality and process better.
Educate and encourage Project Teams to learn about and understand BIM to add to their skill sets.
As management, we need to ensure we are getting value for money. Fees are approx 0.10% of the contract cost but when the lump sum is viewed it is considerable. We therefore need to ensure the BIM consultant is proactive and helps with quality output.
AWARDSOur use of BIM has been recognized in 2010 on Asian House, 2012Bisney Road via Aecom, and 2013 for University Heights by AutoDesk and HKIPM
Maybe 2014 we will try again!
