How many people Singapore's construction industry employs, how many it is likely to need to 2030, and what could change that. Every figure comes from a published source — MOM, BCA, SingStat, HDB, URA, JTC, MOE, MOH — and is linked where it is used. What is a model estimate is labelled as one, with its back-tested error. For a single site, use the Manpower Predictor; for a programme of projects, the Portfolio.
Workers needed against workers available
Employment in construction to 2025 (MOM), and the workers the next five years' work needs, as a range from BCA's low and high forecasts. Change a figure below and the chart, the headline and the table follow.
Trends — the last two, three, four and five years
Growth a year (compound) over each window to the latest year, from the official series. Work Permit holders are published only for construction, marine shipyard and process together after 2019. Dollars are nominal.
By what is built and by client — housing, civil works, HDB, JTC, MOE and MOH, and the private sector
Workers implied by each part of the industry's output: its work done (BCA progress payments) times the industry's workers per S$1 million that year. A proxy: public residential is mostly HDB, public industrial mostly JTC, public institutional mostly MOE and MOH (with the small public commercial line, so every published dollar is counted); and each is costed at the industry's average, not its own. The workers are everyone employed in construction — on sites, in precast yards and in offices — shared out by dollars. They are not a count of people on each client’s sites. The private sector is every private home, factory, office and school together, so it is split by what it builds, as the public sector is. Housing is the exception to the dollars: a private home carries about three times the dollars of an HDB flat but not three times the labour, so HDB and private housing share their workers by homes under construction, weighted by the BCA Code’s labour a square metre (the table below the chart).
Why housing is not a bigger share, though most projects are housing. Workers follow the work done, not the number of projects. HDB alone had 127 projects on site in January 2026, about S$53m of work a year each; civil works are few contracts but each is large and long — the Cross Island, Jurong Region and Thomson–East Coast extension lines, the North–South Corridor, the Deep Tunnel Sewerage System (about S$10b in all, PUB), Tuas Port and Changi T5 are all on site at once, and scarce land sends them underground and offshore. Grouped by what is built, housing is still the largest kind of work in 2025 (about 31% of the workers), civil engineering next (25%). Civil work may use more plant and fewer hands a dollar than building, but no official source gives a figure to correct it with, so it is shared by dollars like the rest.

|---|---|---|
| Everyone employed in construction: 566,800 at December 2025 | Fact — official count | MOM, M182841 |
| Work done in each year by sector and type (housing, civil engineering, institutional, industrial, commercial) | Fact — official, in dollars | BCA, M400221 |
| Homes under construction: 91,941 HDB flats (31 Mar 2025), 30,138 private homes (end 2025) | Fact — official counts | HDB; URA, M400391 |
| Site labour a m²: public housing 0.439, private housing 0.319 m² a man-day | Fact — official baseline | BCA Code of Practice on Buildability 2022, Annex C Table 4 |
| Workers by client, or by type of work | Not published by any agency. The chart estimates it: everyone employed is shared out in proportion to the dollars of work done, every dollar alike. | method on this page |
| HDB against private housing | Estimate: their workers together are shared by homes under construction and the Code’s labour a m², taking homes as similar in floor area (no official floor area for homes under construction) | method on this page |
| HDB = public residential, JTC = public industrial, MOE and MOH = public institutional | Proxy: BCA publishes by sector and type of work, not by agency | BCA, M400221 |
