Q: Your company has applied for funding under BCA’s BIM Fund. Without the funding, would your company have embarked on BIM? If yes, why and if no, why?

A: Without the BCA’s BIM Fund our company would still start the BIM to improve our capability and productivity. However, we would buy less number of BIM Software licenses without the BCA’s BIM Fund supporting us. With BCA’s BIM Fund we will be able to purchase more software and train more staff concurrently. This makes our adoption of BIM at much faster pace.


2. Q: Some of the challenges faced by companies in implementing BIM are the change of mindset and manpower training. In these aspects, how does your company help the staff to transit from 2D to 3D modelling and motivate them to go for training? What are the training programmes that your company has or intend to put in place to build up your staff members’ capability and capacity in BIM?
A: Traditionally we have already adopted 3D modeling to do shop drawings. By using BIM we can further enhance our 3D capability. Currently all our designers are trained to use BIM through our in-house training programme. If further training is needed we can do it on-line consultation for clarification or request the expert from the software vendor to conduct training in our own office.

3. Q: Can you give us one or two examples of other issues your company faced when implementing BIM in your projects and how these were overcome?
A: One of the issue is the mesh generated by the software is always rectangular shape. We cannot further edit the mesh, e.g. omitting one or two distribution bars. We have highlighted this issue to our vendor and hopefully they can upgrade their software to edit the mesh accordingly.

The other common issue is the creation of the library in the system of BIM Software. In the beginning it will take more time to draw 3D such as cast-in-items and connection details, but once the library is fully developed, it will be very useful for our future projects.


4. Q: Can you share with us some of the lessons learnt in your company’s BIM implementation and what are the things that other companies should look out for when implementing BIM?
A: To start a BIM implementation is always difficult and slower compared to the familiar conventional methods that we had been doing since many years ago. The company must have strong willingness to learn BIM. It means more time, hardware, software and effort to be spent to prepare the shop drawings with BIM oriented. More BIM experienced designers will produce faster, correct, representable and accurate shop drawings.

5. Q: With BIM becoming more widely adopted in the international arena, how will your company prepare for this new era of using BIM technologies for projects?
A:  Our company trained all designers to learn and use BIM. As a team, our designers discuss and help among each other. As such the learning process will be faster compared to individual learner. Using BIM, the shop drawings will be more accurate, informative, easily visualize (3D), avoid discrepancies and easier to check whether the design is workable. A clash detection feature will identify the problem early during the design stage rather than during the installation. Therefore, as a precaster, we can demonstrate to our clients that we are more cost-effective solution provider by using BIM to serve the valuable clients better.

6. Q: What else do you think BCA can do to help the industry move beyond just 3D modelling and project collaboration in BIM?
A: Currently the drawings we received from Consultants (Architect, Civil Structure and M&E Engineers) are still in 2D-drawings. BCA should implement submission procedure to insist all consultants to submit their drawings using BIM software. The 3D-modeling with detail information (e.g. M&E services, Structural framing, Architectural finishing etc.) at the beginning of the project will cut down the unnecessary delay and rework caused by the lack of information and discrepancies that likely to happen in 2D-drawings and hence more productive for our designers to produce the shop drawings.
