Employment fell in the construction sector last month, ending a five-month period of jobs growth.
The AIB Ireland Construction PMI report in February shows staffing levels were scaled back midway through the opening quarter of the year.
It comes at a time when there are significant concerns over housing output, with CSO figures showing there was a drop in the completion of new homes last year.
Some construction companies reported that workers had moved on following the completion of projects, while builders continued to increase their usage of sub-contractors modestly.
