Engineers awarded for their outstanding design feats

Sunday, 13 May 2012

- Awards for engineers behind projects Circle Line Stage 5, Flower Dome, and Cliveden at Grange for their engineering designs in overcoming challenges and ensuring site and public safety 
- Merits for eight other engineers who were involved in residential and commercial projects

Singapore, 13 May 2012 - The Building and Construction Authority (BCA) announced the winners of the 2012 Design and Engineering Safety Excellence Awards (DESEA). The award winners - professional engineers involved in Circle Line Stage 5, Flower Dome, and Cliveden at Grange projects - were picked from 16 entries by a panel of experts from the industry. One of Singapore's top accolades for excellent engineering design and safety in the built environment, the BCA Design and Engineering Safety Excellence Awards was introduced in 2008. The Award recognises professional engineers for developing excellent design solutions that overcame challenges, while maintaining high safety standards for their projects.

Here are the award winners (in no order of merit):

Circle Line Stage 5 (Civil Engineering)

Engineers (Er.) Peter Lee Chung Shek and S. Mahatma from AECOM Singapore Pte Ltd had to construct twin bored train tunnels and tracks (total length = 4.2km) for Circle Line Stage 5, which runs under one of Singapore's busiest viaduct and roads. Adding to the complexity was the close proximity of the underground tunnels to buildings on both sides of the viaduct and roads.

The project also involved tunnelling under two existing old shophouses and a canal without affecting their structural integrity. At certain points, the wall of the train tunnel was just two to three metres away from the viaduct's bored pile and the underground structures of buildings nearby.

Flower Dome, Gardens by the Bay (Institutional & Industrial)

Er. Foo See Lim from Meinhardt Group had to build Singapore's first iconic waterfront indoor garden at Gardens by the Bay. Besides his client's requirements for the buildings to house plants which thrive in cool climates, the two indoor gardens must not have any structural columns within the building of 175m width and 123m length.

Er. Foo came up with a solution - involving arches and gridshell - that not only made the indoor gardens structurally safe but also aesthetically pleasant. To construct the unconventional building structure, a series of temporary towers and decks which support both the arches and gridshell were erected. They were built simultaneously and symmetrically so that gridshell and the arches could be constructed safely.

Cliveden at Grange (Residential)

Er. Lauw Su Wee of LSW Consulting Engineers Pte Ltd had to construct four tower blocks of 24 storeys each on a site that has a three-metre wide drain cutting across it. Due to the circular architectural design of each tower, every curve wall on each floor was designed and its measurements determined accurately using various computer software applications before they were constructed on site. Then, like "Lego", each precast wall component was lifted and placed above one another, one floor at a time.

This construction method enabled the construction to be more buildable, achieved better quality of work and reduced the need for external scaffold. This resulted in a safer working environment. To fulfill the developer's requirement for its intended residents on each floor to have a panoramic view of the city, each tower is supported by three steel columns. Each steel column has a cross-sectional area of an A4-sized paper.

Outstanding and safe engineering designs

Commenting on this year's award winners, the chairman of the assessment committee and BCA's board member Mr. Pek Lian Guan said: "We congratulate all of the 2012 DESEA winners. The assessment committee was impressed with their work in resolving site constraints, problems and clients' requirements with excellent engineering designs in the 11 projects that were awarded. The three award winners stood out because of their outstanding designs, and how they had raised the safety standards of building projects in Singapore to a higher level."

BCA's director for building engineering Er. Chew Keat Chuan added: "With more and more complex and iconic projects being built, safety must and continue to remain the number one priority in any development. The DESEA are given to these professional engineers in recognition of their outstanding achievements in ensuring safety. Hopefully, this will steer the industry towards greater emphasis on engineering designs and inculcate a strong safety culture among building professionals in developing a safe built environment for Singapore."
