Prefabricated Prefinished Volumetric Construction (PPVC)

Prefabricated Prefinished Volumetric Construction (PPVC) enhances construction productivity, quality, and site conditions by enabling modules to be built off site and installed efficiently on site.

“Prefabricated Prefinished Volumetric Construction (PPVC)” means a construction method whereby free-standing volumetric modules (complete with finishes for walls, floors and ceiling) are – 

  1. Constructed and assembled; or 

  2. Manufactured and assembled 

in an accredited fabrication facility, in accordance with any accredited fabrication method, and then installed in a building under building works1.

1As defined under the Building Control Act

Why use PPVC

  • Improved Productivity - PPVC can raise productivity by up to 40% in terms of manpower and time savings, depending on project complexity. PPVC has been demonstrated to reduce structural floor cycle time and potentially reduce the total construction time per floor (i.e. Inclusive of architectural works), by up to 30%.

  • Reduction in Construction Time/Duration - On average, PPVC construction/projects have achieved 1 to 2 months of time savings over conventional construction methods with some projects achieving 4 months or more time savings.

  • Better Construction Environment - With most installation activities and manpower shifted offsite, there is less dust and noise pollution, and improved site safety.

  • Improved Quality Control - Off-site fabrication in a controlled environment leads to better precision and higher quality end products.

What to consider when using PPVC

  • Early contractor involvement - Developers or project managers should involve PPVC suppliers, manufacturers and the Main Contractor during the design phase, to help develop effective technical solutions for the project. For example, material choices affect module size and number, as module weight is a key factor in hoisting.

  • Site and project management - Road and site access must support the delivery of large, heavy modules. Instead of storing many large PPVC modules on site, Just-In-Time (JIT) installation helps manage limited storage and avoid double handling. Cranes deployed on site must be appropriately sized and strategically placed for efficient module installation.

  • Maintenance, replacement and renovation - For residential projects, developers should develop a homeowner user manual upon project completion to be provided to both individual homeowners and the Management Corporation Strata Title (MCST). Homeowners should engage trained renovation contractors who follow the provided instructions and use suitable tools.

Compliance with regulations

  • Agency requirements - The design, construction and installation of the proposed PPVC system for building construction shall comply with the requirements by the respective agencies such as BCA, Land Transport Authority (LTA), Ministry of Manpower (MOM), National Environment Agency (NEA), Public Utilities Board (PUB), Singapore Civil Defence Force (SCDF), Urban Redevelopment Authority (URA), Housing and Development Board (HDB) and JTC Corporation.

  • PPVC requirements - To ensure the reliability and durability of PPVC systems, PPVC adoption in projects must meet the requirements specified under the prevailing Code of Practice on Buildability and its addendums (if any).

  • Mandated use in specific sites - Since 1 November 2014, PPVC is required for select non-landed residential developments under the Government Land Sales (GLS) programme.Details can be found in the Building Control (Buildability and Productivity) Regulations and the prevailing Code of Practice on Buildability.

Case studies on PPVC

  • PPVC Case Study - The Clement Canopy [PDF, 533 KB]

    • The Clement Canopy is a 505-unit residential condominium featuring two 40-storey towers, making it the world's tallest concrete PPVC building. The project used 1,866 six-sided concrete modules weighing 26-31 tons each. While basement and first floors used conventional construction, levels 2-40 adopted PPVC technology. Benefits achieved included shorter construction duration, higher workmanship quality, improved safety, and reduced disruption to nearby schools. 

  • PPVC Case Study – The Brownstone [PDF, 408 KB]

    • The Brownstone Executive Condominium (EC) was the first Private Residential Non-Landed (RNL) Concrete PPVC development in Singapore. By combining controlled off-site manufacturing with organised on-site assembly, the project achieved significant productivity improvements, stringent quality control, and environmental benefits. The project achieved up to 4 months of time savings and 20% manpower savings at the project level, when compared against the conventional/prevailing method of construction during its time.
