Bedok Mixed Development

BCA BIM Awards 2014 (Projects): Bedok Mixed Development

Key Features

  • The use of BIM to review complex façade design and to enable the generation of the final cutting list for the panels
  • Extensive involvement of specialist contractors in defining and building the BIM models

Q: Could you tell us a bit about yourself and your project and how BIM is being used in this project?

A: As one of the Directors involved in Bedok Mixed development, I was involved in from the onset of the project as early as 2011 when the land tender was won by our client, Capitaland Limited. This integrated development consists of a retail mall , a bus interchange and a 578 unit residential development all vertically stacked above each other presents the team with multiple challenges of design integration and coordination amongst the different components.

Encouraged by BCA’s efforts in promoting BIM adoption in the industry as well as DCA’s earlier pilot projects using BIM for smaller scale projects or localised studies, DCA decided to adopt BIM for this large scale integrated mixed use project, ahead of many of what our counterparts were doing at that time. As the lead consultant of the project team, our client, Capitaland and the collaborating consultants and the main contractor also similarly adopted BIM for the design stage to the construction coordination.


2. Q: What benefits did the project team enjoy from the use of BIM in this project?
A: The unique characteristic of this mixed use development presented the team with multiple challenges of coordinating the M&E services for each component ( the retail , Bus Interchange and the residential ) such that they do not encroach into another party’s stratum. As each component is vertically stacked above each other, this is not an easy task. BIM was used extensively during the technical coordination for the routing of overlapping services in order to achieve the required headroom.

Another key area where BIM was used was carrying out the design of the 3D curved façade of the retail mall facing New Upper Changi Road.The first BIM model of the façade was provided by DCA to the main contractor and the specialist façade sub‐contractor for their detailed design development. The development of the final façade in BIM allowed fabrication panels to be extracted easily from the model .

Other related items such as the curved structural steel pipes and the individual LED façade lighting points were also coordinated using the 3D model to facilitate fabrication and coordination of the M&E services.Both examples cited above where BIM was extensively used allowed the us to reap better time‐savings when it comes to coordination and the preparation of the necessary shopdrawings for approval as prior understanding of how the design was already sorted out through the review of the BIM model.


3. Q: What obstacles did you overcome when adopt BIM for this project?
A: Bedok Mixed development embarked on BIM in late 2011 where the local industry was still in its infancy stages of BIM implementation and familiarization. One of the key obstacles we faced were the lack of available manpower who were trained in BIM at that time . We also had to adapt the conventional ways of doing coordination and checking on paper to rely on relevant software and hardware such as a projector screens and cloud computing to handle the large sizes of data files that were being exchanged amongst the team members in this BIM collaboration effort.

4. Q: What areas of transformation that the industry should undergo to improve its productivity over the next few years as the use of BIM becomes more extensive?
A: As BIM becomes more extensively used amongst the industry members, one consideration is to have participation of the contractor at the earlier design stages so that the project team is able to work towards using BIM to achieve higher extent of prefabrication or modular design for improved productivity.

Q: Could you tell us a bit about yourself and your project and how BIM is being used in this project?

 

A: BIM was required by the Client to be used in this project to reap the benefits of BIM.

It was used in the coordination of the Builder’s works for this Design & Build Project (Architectural design, M&E, Clash Detection Report & RFI submission).


2. Q: What benefits did the project team enjoy from the use of BIM in this project?
A:  Via the virtual environment in BIM, we are better vision to “see” the space and highlight for areas of concern which if done in 2-D would require mental visualization of the space. A number of such instances were pick-up early in the design stage, highlighted via RFIs for discussion and remedies were found to correct. Also due to the mixed development nature of the project, strata concerns require segregation of services for future maintenance. BIM is able to minimize the instances of services crossing different strata.

3. Q: What obstacles did you overcome when adopt BIM for this project?
A: The project started in end-2011. Then the industry in Singapore was in it early phase of BIM implementation. Manpower resources was limited, and must couple with steep learning curve to comply with project duration, we had to engage an external BIM consultant to help training our staff and build-up their BIM skills, develop the base model and handhold our team to bring them up to the speed for productive performance required for the project needs.

4. Q: What areas of transformation that the industry should undergo to improve its productivity over the next few years as the use of BIM becomes more extensive?
A: More skilled BIM operators and coordinators need to be trained to fulfill industry needs. To fully reap the benefits that BIM can provide, expertise need to also exploit the 3-D, 4-D, 5-D and the Facilities Management capabilities of BIM.
