 SINGAPORE BUILDERS DIRECTORY 2020/2021
 City Developments Limited (CDL) is another forerunner in the DfMA journey. The success of their first and voluntary PPVC project, the Brownstone Executive Condominium, paved the way for subsequent PPVC projects such as the Tapestry (TOP Oct 2021) and Whistler Grand (TOP Oct 2022). The Brownstone EC featured some 5,000 PPVC modules casted from 66 different mould designs, and is likely the world’s largest and first-of-its-kind application of concrete PPVC for a large-scale private residential development. By using the PPVC method, the Brownstone EC increased productivity by over 40 percent, compared to conventional construction methods.
To accelerate DfMA adoption, BCA enhanced its Buildability Framework at the end of 2019. Large (25,000 square metres and above) residential (non-landed) developments now need to meet a higher buildable design score through adopting more advanced DfMA technologies. This was to encourage more innovative solutions from the industry, as long as they meet the stipulated productivity outcomes, and in recognition of the fact that developments of this size are able to capitalise on the benefits of DfMA and enjoy economies of scale from off- site (factory) production.
To meet this strong upcoming demand for DfMA, BCA has also catered more sites in Singapore for Integrated Construction and Prefabrication Hubs (ICPHs) to build up the supply capacity. The 4th and 5th ICPHs by Soilbuild and Teambuild have been operational since last year and the 6th ICPH by Hong Leong- Sunway is slated to be in operation by 2022. At the end of 2019, BCA released two more ICPH- sites at Jalan Gali Batu, for tender.
INTEGRATED DIGITAL DELIVERY (IDD)
Digitalisation continues to be a key transformation focus area and Integrated Digital Delivery (IDD), has proven to be a game changer for the sector
since its launch in November 2018. IDD refers to the use of digital technologies to integrate work processes and connect stakeholders working on the same project throughout the construction and building life-cycle: namely, from design, to off-site fabrication, to on-site assembly and construction, and finally to operations and maintenance.
In the area of IDD, there are now 35 public and private sector projects piloting IDD, compared to 12 projects in 2018, making steady progress towards BCA’s 2020 target of piloting 40 to 60 IDD projects and building up IDD capabilities in 150 to 180 firms. The use of IDD in the built environment has reaped benefits such as productivity gains, with closer collaborations among stakeholders throughout the building life cycle; reduction of waste by minimising rework; and improving quality and site safety. Firms can tap on the Productivity Innovation Project (PIP) scheme under the BuildSG Transformation Fund (BTF) to support their IDD implementation.
Firms which have embarked on the IDD journey, have reported an increase in productivity, and a reduction in costs. For example, BHCC Construction shared that it aims to achieve 30 percent time savings during the design stage of a project by using a Virtual Reality (VR) collaboration system which allows members of a project team to collaborate and coordinate designs by merging Building Information Modelling (BIM) data into a single model. During the construction stage, BHCC Construction achieved 25 percent time savings by using a project management platform that enables all project parties to be updated on the progress of the project, including status tracking of precast components. BHCC Construction also targets to achieve 25 percent time savings by digitalising its management of site safety records.
