 sector construction demand over the medium term will continue to be supported by various mega infrastructure projects. BCA expects private sector construction demand to stay at a moderate level in view of the likely continued global economic uncertainties and the current overhang in the supply of private residential housing units. The planned expansion of the two Integrated Resorts at Marina Bay Sands and Resorts World Sentosa could provide further upside to private sector demand, depending on their eventual construction timelines and phasing.
Since the launch of the Construction Industry Transformation Map in 2017, the built environment sector has been engaged in three key transformation areas: Design for Manufacturing and Assembly (DfMA), Integrated Digital Delivery (IDD) and Green Building, underpinned by research and innovation and manpower development. This will improve construction processes and methods and ultimately create new and better jobs for those working in the sector.
A key strategic thrust in the industry’s ongoing drive to raise construction productivity is Design for Manufacturing and Assembly (DfMA). Through the DfMA approach, building parts are manufactured in factories before being transported onsite for assembly, enabling projects to be completed faster, cleaner, quieter and with better quality.
Over the course of more than 140 DfMA projects, this approach has achieved higher quality, productivity and sustainability in a traditionally manpower-intensive construction
industry. Three Singapore firms have also been investing in capability building to undertake DfMA projects. To date, more than 80 (architectural, C&S, engineering and M&E) consultancy firms and about 60 builders have undertaken over 140 DfMA projects in Singapore. Several leading firms have started investing in highly automated plants to produce higher quality prefabricated components and modules for DfMA in Singapore.
In all, the built environment industry has, since 2010, achieved a cumulative site productivity improvement of about 15 percent. The DfMA adoption rate by the industry was at 22 percent in 2018. As of 2019, the built environment industry has achieved a 31 percent DfMA adoption rate and is on track to reach the target of 40 percent this year. Looking further ahead, BCA aims to raise the adoption rate to 70 percent by 2025.
In the public sector, the Housing and Development Board (HDB) continues to take the lead in adopting DfMA in their building projects where 75 percent of all its units launched in 2020 will adopt DfMA methods such as Prefabricated Pre-finished Volumetric Construction (PPVC) or Advanced Precast Concrete System (APCS). HDB has adopted PPVC since 2016, and will be adopting PPVC for 30 percent of units launched this year. PPVC involves the fabrication of modules off-site in a controlled manufacturing environment, which are later brought to site for assembly.
As the public sector continues to take the lead in the adoption of DfMA, the BuildSG Transformation Fund (BTF) has set aside S$120 million under the Public Sector Construction Productivity Fund (PSCPF) for public sector agencies to adopt DfMA in projects launched by 2021. Private sector projects may continue to seek funding support for projects which adopt DfMA technologies voluntarily through the Productivity Innovation Project (PIP) scheme.
