9. 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

10. 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.

11. 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.

25. TW5 Cityside. Mixed development of 949 units
and commercial podium
Includes temporary
relocation of
PTI, reprovisioning of a
RCP, providing a
temporary car park,
diversion of sea
water mains and the
demolition of the existing
multi story Car Park, PTI
5 footbridges and RCP.

26. Simulation - Demolition Sequence

27. Consultants: Design Verification
TW5 - Existing Building Transport Complex Demolition

28. 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

29. 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.

40. 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

41. 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.

42. 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.

43. 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.

44. AWARDS
Our 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!
