HDB’s BTO Construction Push: Smart Hoists, Screeding Robots and Precast Parts

HDB is combining automated site equipment with more standardised, factory-made building components to reduce labour-intensive work on Build-To-Order (BTO) projects. The intended payoff is higher productivity and, potentially, earlier completion—not a guaranteed cut in buyers’ waiting times.34

Where smart hoists and screeding robots fit

Smart hoists are automated temporary lifts used on construction sites. HDB plans to deploy them at about 50% of new BTO sites tendered from 2027.3 Separately, it plans to expand the use of screeding robots at more BTO sites. The laser-guided robots level and smooth floor surfaces, replacing some repetitive manual work.36

The technologies are being scaled up to improve productivity and reduce manpower needs, but the provided reporting does not establish a site-by-site staffing reduction or time saving for either machine.37 The 50% target applies to smart hoists; it should not be read as a separate deployment target for screeding robots.3

What the trials show—and what they do not

HDB’s construction-transformation projects at Tengah offer a broader measure of progress. Both were reported to be on track for a 25% improvement in site productivity over a baseline of 0.6 square metres per man-day, using approaches that include prefabrication and standardisation.2 That is a project-level productivity measure, not a 25% reduction in construction time or a result attributable solely to smart hoists and screeding robots.

Faster completion remains a possibility rather than a quantified promise for future BTO buyers.323

The precast catalogue and the quality question

HDB is also moving to further standardise precast building components. A September 25 report says the Enhanced Precast Components Catalogue is scheduled to launch on September 29, 2026, and apply to all tenders from December 2026.8 Precast construction moves component manufacturing off-site before assembly on-site; HDB says this approach supports better quality control, safer working conditions and less dependence on manual and unskilled labour.4

A report about the wider package of technology and standardisation measures mentions potential project man-hour reductions of up to 20%.7 The available evidence does not establish that the catalogue alone delivers that saving. Nor does it specify which components the enhanced catalogue covers or how it will preserve distinctive designs. Standardising components should therefore not be mistaken for a documented promise that every project will look alike—or proof of a particular design safeguard.

What helps contractors adopt the technology?

Industry-wide measures could lower barriers to adoption. The Building and Construction Authority (BCA) has announced the removal of the requirement for an operator to be stationed inside a smart hoist; that regulatory change does not mean hoists can operate without safety requirements.20 BCA is also waiving space rental fees for productivity-focused technology trials at the Built Environment Innovation Hub’s sandboxes for two years from July 2026.2021 Proven digital solutions are being shared through the Integrated Digital Delivery Technology Alliance.18

These are broader construction-sector supports, not evidence of a specific HDB grant, co-funding rate or training package for contractors in this rollout. For now, the clearest commitment is the planned equipment deployment; the effect on individual BTO completion dates remains to be demonstrated.3
