Over the past year, the UK's construction workforce has fallen by 234,000 – a 10% reduction – and now stands at 2,045,000.
It is the hardest hit of all the UK's business sectors.
However, there were fewer redundancies in construction during the first quarter of the year: 29,000 compared to 34,000 who were laid off in the last three months of 2009.
Redundancy figures for the full year were 143,000.
The discrepancy between the figures for job losses and redundancies is thought to be due to self-employed workers dropping out of the industry.
The size of the construction workforce is expected to shrink further as cuts in public spending start to bite.
