ABSTRACT
South Beach development was conceived as a response to Singapore’s aspiration to be a ‘city
in a garden’. In keeping with this aspiration to be a garden city development, the project takes
its primary cue from nature and its ability to provide natural filters and regulators that act in
harmony with the local climate. As a tree provides shelter from the sun combined with
beautiful dappled light, shelter from rain and an open natural environment beneath its boughs
– the development is covered with a similar environmental filter inspired by the protection
offered by a tree canopy. The basement/podium forms a green spine with interlinked
courtyards. The sunken garden entry plaza at the entrance to South Beach with connectivity
to the Esplanade MRT Station is an example of open and public space within a private
development. The towers are shaped to allow enhanced views towards the Central Business
District. The Tower Bases gracefully cut back to allow the Green Spine to stretch through the
site. Sky-terraces are cut from two towers and climb vertically as a cascade of green spaces.
The South Beach development is intended as an iconic landmark and a showcase of
sustainability strategies. A key feature of the design is the “environmental filter” canopy that
covers the open space, linking the two towers, covering the podiums and heritage buildings.
The microclimate within this canopy is designed so that it caters to the specific activities that
are envisaged on the site. The development represents a considerable challenge to the
planning and design skills of engineers. Sophisticated software is mated with technical know-
how to solve complex engineering problems from concept to design to construction. This
paper summarises some of the engineering challenges faced during the design of the
development; from deep excavation in poor soil condition to two high-rise towers with
sloping faces to an undulating, unsymmetrical large-span canopy.
Soh Seng Siong has relevant abilities in the areas of design and supervision in civil, structural and geotechnical engineering projects. He has more than 30 years of experience in these disciplines and is a registered Professional Engineer (Civil), Professional Engineer (Geotechnical) as well as an Accredited Checker and Specialist Accredited Checker (Geotechnical).
Some of the major innovative designs are the triple donut configuration (circular diaphragm wall) for construction of deep basements, reinforced concrete ring beam strutting system for basement excavation adjacent to existing MRT station, 6 levels of top down construction, load bearing precast wall design and pile-raft foundation. Currently he is involved with the design of foundation and substructure of Capitol Project, Tanjong Pagar Mixed Development, Downtown Line 3 and Thomson Line MRT projects.
In the specialist consultancy service to BCA, he was involved in the underpinning of 30-storey building providing geotechnical and structural assessments.
Er. Edwin Ong Beng Koon Associate, Arup Singapore Pte Ltd
An engineer since 1989, Edwin has been leading teams to plan and design the structural framework for buildings, preparation of tender and construction drawings and supervision of works carried out on the construction site. His experiences include coordinate design information between owners, other consultants and contractors for Design and Build Development, preparing tender document and contract administration for repair/retrofitting works and Civil Engineering projects for the Public Utilities Board and development of educational institute projects. He has also served as Resident Engineer at a major project at Changi Airport. Recent projects include the Sportshub, Marina Bay Sands Integrated Resort and City Square Mall.
