PPVC Method Improves Building Quality

SINGAPORE: Crowne Plaza Changi Airport hotel’s new 10-storey extension has reached its halfway mark.

Developed by OUE, the hotel extension is Singapore’s first private sector commercial project to use Prefabricated Pre-finished Volumetric Construction (PPVC) techniques. Rooms complete with finishes, fixtures and fittings were done in China before being shipped to Singapore to be installed on site.  The Brownstone EC executive condo in Sembawang by City Developments (CDL) and related company TID – a joint venture between Hong Leong Group and Japan’s Mitsui Fudosan is Asia’s first large-scale residential project that is also built with PPVC.

Minister for National Development Lawrence Wong visited the site where he witnessed the hoisting process and visited one of the prefabricated rooms.

The first batch of shipments of prefabricated rooms arrived in Singapore earlier this year. The new extension is expected to be completed in June, and will add another 243 rooms to the existing 320.

According to OUE, using the PPVC method has slashed manpower requirements on site by as much as 45 per cent. It added that the use of PPVC has shaved off 17 per cent in overall construction time, with about 40 per cent in manpower savings.

“The Crowne Plaza Changi Airport hotel extension project demonstrates that it is possible to significantly reduce the number of workers required, shorten construction time, improve building quality and even overcome site constraints by changing the way we build,” said Building and Construction Authority CEO John Keung.

“The Government will continue to drive innovation in the built environment sector and help firms to go through this transformation,” he added. “This will help ensure the sustainability of our local firms in the long run, while changing the nature of jobs in the sector.”

Dr Keung also said: “We are very keen to move the industry to manufacturing and assembly rather than doing everything on-site because the working conditions on the site are not the most conducive. So the more you do off-site, the better off you are, in many ways.

“You can do better quality control, the working environment is much better and at the same time, the work on site is less disruptive to the residents and people around the construction site. So there are many of these benefits that we are looking for and it’s quite important for us to do as much as possible.”

Meanwhile, Mr Wong said he is keen for more widespread adoption of such construction technology, and expects the public sector to take the lead in creating that demand.

In particular, he hopes the Housing and Development Board (HDB) will look into such processes, given the scale of its projects.

Said the minister: “Over time, as we see the technology mature, HDB I’m sure will adopt more of these technologies across the board. And I’m sure this is a potential game changer because with HDB doing many repetitions, it’s the same building and the same kind of apartment and you can keep repeating, so potentially the savings are there.

“So HDB naturally will want to be very sure that the technology is safe; and wants to be assured that when it adopts this technology, the quality can be assured, because whatever HDB does will have tremendous impact down the road.”
