Smart tech like robotics, automation to be used at more BTO sites from 2027: Chee Hong Tat
One such effort is the use of robotics for labour-intensive processes like floor screeding.
Singapore's National Development Minister Chee Hong Tat announced plans to incorporate more smart technology, such as robotics and automation, in the construction of Build-To-Order (BTO) flats starting in 2027. This move aims to accelerate the housing supply and enhance construction productivity while reducing the reliance on manpower. So far, the utilization of smart technology has shown promising results, prompting its scaling up at additional BTO sites in the upcoming year.
One practical application of this technology includes using robotics for labour-intensive processes like floor screeding. Conventional methods involve manual setup of level pegs, whereas screeding robots employ lasers as guides, which can level and smooth floors more efficiently before installing tiles or vinyl flooring. Currently, two such robots are being trialled in 80 units at two BTO projects in Bukit Merah and Ghim Moh.
The Minister expects these robots to be tested in at least four more BTO projects by 2027 to evaluate their performance across diverse site conditions, with potential for wider deployment thereafter.
Another innovation is the introduction of smart hoists, temporary lifting systems installed on the exterior of buildings. These hoists offer safety features like obstructions sensors and worker gear detection cameras. With one worker overseeing up to three smart hoists, compared to the need for a dedicated operator with conventional hoists, this improvement saves manpower across multiple blocks and projects, contributing to overall productivity gains.
Chee emphasized that while the enhancement might appear minor, its effects compound significantly across many developments.
Additionally, contractors tendering for selected BTO projects commit to completing them three months earlier under HDB’s shortened time for completion scheme, introduced in 2023. Contractors propose improved productivity methods and technologies for tender submissions. To further streamline construction, an inloader, a heavy-duty transport vehicle with a hydraulic jack, will be utilized to load and unload precast components, eliminating the need for cranes.
HDB is also piloting an excavator for earthworks in Tengah, incorporating satellite positioning and digital terrain models for enhanced precision.
To minimize repetitive tasks for contractors, HDB will release a catalogue of precast components on September 28, complete with detailed specifications and drawings. This catalogue features 17 standard components to ensure consistency while retaining flexibility for distinctive designs. With common specifications across all HDB projects, the catalogue aims to bolster supply resilience by allowing contractors to source standardized components from various suppliers.
The initiative also enables the development of variations for components like facades, bathroom units, columns, and beams.
HDB highlighted that the catalogue helps maintain project diversity despite standardization. At the HDB Awards Ceremony held on September 25, 30 projects received recognition for their achievements in design, construction, engineering, and landscape. Two design consultants, LOOK Architects and 3PA, were awarded for their innovative BTO project designs in Berlayar and Mount Pleasant estates, respectively. Their designs incorporated nature and heritage elements, contributing to the projects' unique identities.
