Higher workmanship quality for new buildings

Tuesday, 6 May 2014

Singapore, 6 May 2014 - Five builders and three developers will be receiving the Quality Excellence Award from the Building and Construction Authority (BCA) for delivering high quality homes. Among the winners are City Developments Limited (CDL) and Woh Hup (Private) Limited, which attained the top accolade of the award - the Quality Champion (Platinum), for the second consecutive year.

The Quality Excellence Award recognises leading progressive developers and builders who have embraced quality workmanship through the BCA Construction Quality Assessment System (CONQUAS) and Quality Mark Scheme, and delivered high quality projects consistently.

To date, six out of the top ten private residential projects in the CONQUAS ranking were developed by CDL, while Woh Hup was the builder for four projects in the top ten ranking.

Other winners include CapitaLand Limited, Allgreen Properties Limited, Dragages Singapore Pte Ltd, Hyundai Engineering & Construction Co. Ltd, China Construction (South Pacific) Dev Co Ltd and Straits Construction Singapore Pte Ltd.

These developers and builders have contributed to higher quality and workmanship standards of new buildings in Singapore over the years. The average CONQUAS score has risen to 87.5 points compared to 82 points five years ago.

Currently, 95% of all new commercial and private residential buildings subscribe to the CONQUAS which is a standard assessment and benchmarking system on the workmanship quality of building projects. Private sector projects subscribe to CONQUAS on a voluntary basis.

While CONQUAS is based on a sampling approach, some private developers such as CDL and CapitaLand have also committed all their residential developments to a more stringent quality assessment programme i.e. Quality Mark for Good Workmanship Scheme.

The Quality Mark Scheme adopts a 100% check on the workmanship quality of internal finishes and water-tightness of bathrooms of each dwelling unit in a private residential development. Individual units that meet the minimum good workmanship standard and do not exhibit any signs of water leakages in bathrooms are each issued a Quality Mark certificate. About 50% of private residential projects subscribe to the Quality Mark scheme.

In a survey conducted by the BCA on managing agents of 82 private residential projects that received Temporary Occupation Permits from 2004 to 2012 as well as cases lodged with the Strata Titles Board, it was found that Quality Mark and CONQUAS projects received 83% fewer complaints on inter-floor water leakage compared to projects that did not undergo the above quality assurance programmes.

"Through independent workmanship quality assessments such as the Quality Mark Scheme, home buyers can expect to receive better quality homes as major defects are detected early and rectified before the units are handed over to them. It also instils discipline in contractors to deliver higher quality standards", said Mr Tan Tian Chong, Group Director of Technology Development, BCA.

"Compared to other developments, Tree House has a better and neat workmanship on tiled flooring and around windows and doors," said Mr Tang Yoon Chuan, homeowner at CDL's Tree House, a Quality Mark project. Mr Liew Kai Zee, homeowner at CapitaLand's recently completed Quality Mark project The Interlace, also commented that the workmanship quality of the finishing of his unit had exceeded his expectations. "Careful considerations were given to blend aesthetics with functionality and utility," he added.

This year, 16 awards and 12 certificates of merit will also be conferred for Construction Excellence. Besides the quality of completed projects, other criteria include safety, environmental consciousness, innovation as well as a strong emphasis on productivity.

Woh Hup has clinched the Construction Excellence Award for four of its projects, with two of its condominiums SAGE and Holland Residences having the two highest CONQUAS scores to date.

With the highest CONQUAS score of 97.9 for SAGE, Woh Hup managed to achieve high workmanship quality through the use of precast technology, where building components such as staircases are manufactured in factories under stringent quality control. The use of productive technologies such as self-compacting concrete for structural works also helped improve the consistency of concrete without the need for mechanical vibrators to compact the concrete.

A key innovation adopted included a raised floor system where granite floor panels are laid in a horizontal grid supported by adjustable vertical pedestals for the pool deck, which eliminated wet trades and enabled better control over the floor level. Also, a composite stone façade comprising a thin layer of marble on top of a honeycombed metal panel for the cladding, improved safety during installation as lesser material is used resulting in a more lightweight fixture.

Other notable projects that have won this year's Construction Excellence Award include HDB's Casa Clementi, Punggol Breeze and Punggol Spectra, the ITE College Central and the Conservatory Complex at Gardens by the Bay.
