Design for Manufacturing and Assembly (DfMA)

Design for Manufacturing and Assembly (DfMA) is a key pillar of Singapore’s Construction Industry Transformation Map (ITM). It is a game-changing method of construction which involves construction being designed for manufacturing off-site in a controlled environment, before being assembled on-site. 

Key benefits of DfMA include:

  • Shorter construction period– Most of the construction is done off-site, reducing the construction time and the amount of manpower required on-site
  • Improved workmanship– Due to stringent quality control in prefabrication factories
  • Reduction in dis-amenities– As lesser construction work is carried out on-site, it causes less disruption to the community

Types of DfMA technologies 

DfMA comprises a continuum of various technologies and methodologies that promote offsite fabrication from prefabricated components to fully integrated assemblies across the structural, architectural and MEP disciplines.


Advanced Precast Concrete System (APCS)

A construction method that adopts precast concrete components and applies features under the ‘3S’ principles of Standardisation, Simplicity and Single.

Mass Engineered Timber (MET)

A building material comprising engineered wood products with improved structural integrity.

Prefabricated Prefinished Volumetric Construction (PPVC)

A construction method whereby free-standing 3-dimensional modules are completed with internal finishes, fixtures and fittings in an off-site fabrication facility, before it is delivered and installed on-site.

Prefabricated Bathroom Units (PBU)

A bathroom module which is preassembled off-site complete with finishes, fixtures and sanitary wares before it is delivered and installed on-site.

Prefabricated Mechanical Electrical and Plumbing (MEP) System

MEP components and equipment that are integrated into a sub-assembly off-site and then installed on site.

Structural Steel

A category of steel used for making construction materials, such as beams and joints.

How Singapore is encouraging adoption of DfMA

Integrated Construction and Prefabrication Hubs (ICPH)

To support the increasing demand for DfMA components, Singapore is developing Integrated Construction and Prefabrication Hubs (ICPHs) with a 30-year lease term.

Generating Demand for DfMA projects

Driving adoption of DfMA is driving adoption of DfMA through Productivity Gateway Framework (PGF) and Government Land Sales (GLS) requirements.

Pipeline of DfMA projects

Pipeline of projects prescribing DfMA technologies – for construction tenders expected to be called within the next two years.
