1.0 DESIGN APPROACH

1.1 The solution derived for the project is a result
of close co-ordination and integration of the
expertise of the various professional
disciplines, focusing on achieving a most
optimal ‘value engineering’ solution meeting all
fundamental requirements, standards set by
HDB. Most importantly, to ensure design is
meets stringently to all mandatory building
bylaws set by the relevant authorities, and also
be able to address security and privacy issues
thru well integrated design features.

1.2 The LUP’s proposal consists of new lift shaft
constructed primarily of steel structure and
cladding panels. Fundamentally, the choice of
construction methodology is to achieve
speedier and neater construction process. Due
consideration is also given to environmental
friendliness thru usage of material selection
which are recyclable and deriving good
detailing for ease of construction, as well as
mitigating future maintenance cost.

Lift Upgrading Proposal

access to the common corridor as well
NEW STEPS
as does not allow a new lift opening to
be created at one of the existing lift
shaft. The creation of a single ramp to
replace the steps proves to be too long
and will also stretch beyond the

to raise the floor level of the existing
