MEDIA RELEASE
BCA CONSTRUCTION EXCELLENCE AWARD 2009 Eight projects rewarded for good workmanship
1. A total of six awards and two certificates of merit will be given out in BCA’s
Construction Excellence Awards this year, out of a total of 15 nominations.
2. The annual competition, first introduced in 1986, principally recognises
builders' workmanship, focusing on downstream post-design work, such as project
management, technical capability and quality of the completed project.
3. Of the eight winners, five were private residential developments. Among
these, there was notable improvement in the quality of the projects and
performance of the winners.
4. Top local builder, Woh Hup Pte Ltd who clinched two Construction
Excellence Awards for Blossoms @ Woodleigh and ICON this year, has clearly
benefited from the BCA Quality Mark for Good Workmanship Scheme. Both
private residential developments achieved high CONQUAS points of 92.6 and
90.4 respectively. Woh Hup is a clear leader in delivering projects with excellent
workmanship. They have the distinction of building 9 out of the 16 private
residential projects which have a CONQUAS score of 90 & above, a rare feat, of
which 7 of these have also received the BCA Quality Mark certification.
5. The BCA Quality Mark scheme, which had its debut in 2002, seeks to
ensure the consistent delivery of quality homes. It has a set of prescribed
standard which assesses the internal finish of every single apartment unit within a
residential project, including water-tightness tests in all bathrooms. Each unit
must attain a minimum score and have no major defects in order for the project to
receive the Quality Mark. To date, some 26,000 residential units have been
committed or assessed under the BCA Quality Mark Scheme. Last year, about
44% of units launched were committed to the Scheme.
6. Building projects that received the BCA Quality Mark have reportedly
scored much higher in CONQUAS and received little or less feedback on defects
from homeowners. Owing to the scheme, potential major defects and leakages in
about five percent of total units assessed were detected and rectified before the
units were handed over to homeowners, thus reducing any unhappiness and
inconvenience to homeowners.
7. Besides Woh Hup’s Blossoms @ Woodleigh and ICON, the other winning
projects are St Regis Hotel, Residences @ Evelyn, Citylights Condominium, The
Tresor, Ferry Terminal at Marina Coastal Drive and 36 Kaki Bukit Place. Details
of the winners are in Annex A.
8. The winners will be receiving the award from Ms Grace Fu, Senior Minister
of State for National Development and Education, during the BCA Awards
ceremony on 27 May 09.
Issued by the Building and Construction Authority on 18 May 2009
About CONQUAS
The Construction Quality Assessment System (CONQUAS ) was introduced in Singapore in 1989 and serves as a standard assessment system on the quality of building projects. It assesses structural works, architectural and mechnical & electrical
works. CONQUAS is widely recognised as the de facto yardstick for quality in Singapore and also accepted internationally as a benchmarking tool for quality. Countries
such as Hong Kong and Malaysia have adapted CONQUAS to their construction
industry. CONQUAS is now a registered trademark in Singapore, Malaysia, China, Hong Kong SAR, United Kingdom, Australia, South Africa, Thailand and India.

St. Regis Hotel
St. Regis Hotel, located right at the junction of Tanglin Road and Tomlinson Road
is jointly constructed by Kajima Overseas and Tiong Seng Contractors. It is 20-
storey high and cladded in glass with 299 Guestrooms.
Key Construction Features
The main constraints were the construction over the existing 9.0m wide and 5.5.m
deep drainage canal across the site and the proximity of high-end private
residences, shopping centre and hotel. With proper planning and good
management, the project clinched several awards for site safety from MOM and
achieved a distinctive CONQUAS score of 92.0.
Key features commendable for the award are as follows:
(a) invented a “Noise Container” hood to control direction and reduced noise
generated during excavation, piling and hacking
(b) saved 20,000m3 of water by reducing, recycling and reusing of water for
stabilizing bored holes prior to casting
(c) re-arranged the carpark lots to reduce the requirement of 3 basement
levels to 2 basement levels
(d) adopted a perimeter beam plus flat slab system instead of the beam slab
system to increase the ease of construction
(e) omitted external scaffolding by using precast perimeter beams, precast
gable end walls and unitized curtainwall. This also reduced the risk of
falling from height and falling objects in the busy town area.
(f) used drywall for internal partition and improved productivity
(g) relocated spray paint work on interior design panels from site to factory for
better quality works and greener working environment

residential buildings with 204 units, a basement carpark, swimming pool and
various recreational facilities. It is located at Woodleigh Close off Upper
Serangoon Road.
Key Construction Features
Woh Hup has demonstrated once again that it had an effective management
system capable of constantly delivering good quality projects as illustrated in this
project which finished with a remarkable CONQUAS score of 92.6 points. This
project also achieved an average 85.8 Quality Mark (QM) score and a clean
safety and environmental compliance record.
Woh Hup completed the project in 29 months and the key features contributing to
the award are as follows:
(a) used system formwork, e.g. aluminium table forms for floor slabs, jump
forms for core walls, etc, to increase productivity and improve safety
(b) used pipe jacking method to divert minor sewer line to avoid opening road
and damaging trees
(c) adopted screedless floor for installation of stones in living and dining areas
(d) the basement was redesigned with openings at side to reduce
requirements for mechanical ventilation. A ductless ventilation system was
used instead.
(e) redesigned the reinforced concrete (RC) Jaccuzi at the roof to pre-
fabricated fibre glass with integrated pump and piping, thus improving
speed of construction and resulting in better finishes
(f) adopted a RC flat slab system with perimeter beam for superstructure. This
system facilitated the use of system formwork and allowed flexibility in M&E
planning especially without the internal beams.
(g) RC stump was constructed on all external half-brick walls to house M&E
points. This prevent hacking the brickwall and enhanced the water-
tightness of external walls
(h) provided 350mm high RC kerb at wet areas to enhance water-tightness

with 95.4% of units passing at the first inspection.
The main constraints were the close proximity to an old temple, MRT station,
hotel, offices & HDB buildings and the tight footprint of the building with limited
space for storage and movement. The construction was further complicated with
the homeowers’ freedom to select layout and finishes.
Builder’s strategy and contribution to improve on safety, environment, productivity
and quality were:
(a) changed the pile foundation to pile-raft foundation to speed up construction
(b) changed the 1st storey beam-slab system to flat-slab to reduce ground
works
(c) adopted a reinforced concrete flat slab design with perimeter to facilitate
use of system formwork and allowed more flexibility to accommodate M&E
services
(d) developed a comprehensive Defects Management Programme to minimise
complaints on defects
(e) used innovative methods / products e.g.
• SETECO formwork system for better aligned and finished gable wall,
• composite aluminium panel (albolic panel) for external facade to
provide a clean and sleek look
• engineered timber flooring to eliminate sanding
• special silicone facade paint was used to reduce dirt
• screedless floor for installation of stone finishes at living and dining
rooms
• used self-climbing tower crane to overcome site constraints

36 Kaki Bukit Place This is a 5-storey industrial building with basement located at Kaki Bukit Place.
Key Construction Features
The industrial building is constructed at a cost of $5.6 million. It was completed in
a very short time of 14 months and still achieved a commendable CONQUAS
score of 82.5 points, especially in the industrial building category. The main
constraints were the proximity of nearby buildings and the narrow congested
entrance road hindering the speed of lifting and delivery of materials.
With careful planning and good site management practices, the builder managed
to complete the building with no lapses in safety and environmental issues. Some
of the commendable features worth mentioning are:
(a) relocated the ramp to basement car park and lowered the transformer and
switch room to basement avoided a costly over $1 million diversion of HT
cable
(b) cost saving for client by replacing the bored piles with RC piles after careful
study of the soil condition. This also significantly reduced the risk of
damaging an underground power cable running across the proposed
building.
(c) some saving for client by replacing the 6m high single sheet glass with 2
pieces of thinner 15mm thick glass panels
(d) replaced screed floor finishes with power float finishes reduced wet trade
and saved time in construction
(e) redesigned the window cladding so that it could be installed from inside the
building, thus omitting the need for external scaffold and reducing the risk
of falling from height
