CDL will be the first developer in Asia to introduce the prefabricated prefinished volumetric construction PPVC method in a large-scale residential development, The Brownstone EC (executive condo) project at Canberra Drive. The EC will be constructed using some 3,300 roomsized units – likely the largest application of PPVC in the world. Other executive condo in the vicinity include Signature At Yishun EC, at Yishun St 11 and Skypark Residences , Parc Life at Sembawang Crescent.
The Brownstone executive condominiums comprises eight 10-to-12-storey blocks with an estimated 636 units. This development was an ideal candidate for the use of PPVC because of the condominium’s modular nature, CDL said.

The use of PPVC for the EC is expected to increase construction productivity by more than 40 per cent and will save some 55,000 man days, compared to if CDL, developer for The Criterion EC, were to use the conventional construction method, it said. As a result, the EC is expected to be completed four months ahead of schedule.
“Adopting PPVC also enhances worksite safety as prefabrication of the building modules in factories means fewer workers on site which in turn leads to fewer accidents and less down time,” CDL said.
On top of that, quality control in factories result in uniformity of prefabricated components, which in turn leads to a reduction in the wastage of materials.
