Two GLS sites to adopt PPVC

Two upcoming Government Land Sales (GLS) sites at Yishun Avenue 4 and Jurong West Street 41 will need to adopt Prefabricated Prefinished Volumetric Construction (PPVC), an advanced technology in construction.

These sites are scheduled to be released for sale in November and December 2014 respectively.

This is in line with the revised Building Control (Buildability and Productivity) Regulations announced by the Building and Construction Authority (BCA), which now requires using labour-efficient construction methods and building design to improve construction productivity.

From 1 November 2014, projects are required to use prefabricated and standardised components. Specifically, all non-landed residential developments are required to adopt drywall as internal partitions for dry areas. New projects will also have to be built based on standardised floor heights and building components (such as precast staircases, precast refuse chutes and doors).

Next, they have to meet higher minimum Buildable Design and Constructability standards to make buildings easier to construct and encourage the use of efficient construction methods and processes.

Lastly, residential non-landed sites, including Executive Condominiums (EC), and the residential component of mixed-use sites sold under the Government Land Sales (GLS) programme will have to adopt productive technologies for projects, such as using Prefabricated Bathroom Units (PBUs, pictured).

The adoption of PPVC will also be imposed on selected GLS site.

PPVC involves assembling whole rooms or apartment units complete which are produced off-site and installed on site in a Lego-like manner. PPVC also enhances worksite safety as prefabrication of the building modules are done in factories.

Other projects which have adopted PPVC include a student hostel at Nanyang Technological University (NTU) and a building extension to the Crowne Plaza Changi Airport Hotel.

An upcoming Executive Condominium (EC) in Sembawang by City Developments Limited (CDL) will also be built using PPVC, making CDL the first developer in Asia to adopt PPVC for a large-scale residential project.
