The latest survey also pointed to the sharpest rise in new orders since December 2015.
The headline seasonally adjusted IHS Markit/CIPS UK Construction Total Activity Index reached a score of 52.6 in February, up from 48.4 in January, and above the 50.0 no-change value for the first time since April 2019.
Moreover, the latest reading signalled that the overall rate of construction output growth was the fastest for 14 months.
The reported growth came despite weather conditions leading to delays on many sites.
Residential activity remained the best-performing construction category but commercial work also returned to growth in February, posting its fastest increase in business activity since November 2018. However, civil engineering activity fell albeit much less than recently.
The intake of new orders rose at the steepest recorded for just over four years. Survey respondents widely commented on greater tender opportunities and the release of spending that had been delayed in the run up to Brexit.
Demand for subcontractors picked up for the second month running and to the greatest extent since December 2018.
Tim Moore, economics director at IHS Markit, which compiles the survey, said: 鈥淔ebruary's survey data adds to signs that the UK construction sector has started to rebound after a downturn through the second half of last year. Growth of business activity was stronger than at any time since the end of 2018, supported by the fastest rise in new orders for just over four years. Some construction firms suggested that the recovery in output would have been even stronger had there not been disruptions on site from severe weather conditions in February.
"There were widespread reports that pent-up demand released since the general election had helped to boost workloads, especially in relation to house building and commercial construction projects. Civil engineering activity moved another step closer to stabilisation in February. A number of survey respondents commented that contract awards from HS2 and other major transport projects had the potential to boost infrastructure work at their businesses in the year ahead.
"While construction order books have begun to recover in the opening part of 2020, the fly in the ointment is the uncertain impact of the coronavirus outbreak on UK economic growth prospects. A renewed slowdown could see domestic investment spending put back on hold and dampen the outlook for the UK construction sector."
Duncan Brock, group director at the Chartered Institute of Procurement & Supply, added: "After a sustained period of contraction in construction last year, the resurgence in levels of new work at the fastest rate since December 2015 was a surprising but much-needed development for a sector that was on its knees. As the blocks of December鈥檚 election and Brexit uncertainty were largely removed, it was the residential sector that was the main winner with the fastest escalation in housebuilding since July 2018.
"Purchasing levels rose at their fastest rate for over a year across the construction sector meaning unprepared suppliers bore the brunt of the upsurge. Their performance deteriorated again this month as delivery times and stocks of raw materials came under pressure.
"Should there be another sudden rise in purchasing activity in March, we are likely to see more challenges in supply chains, until suppliers have a chance to catch up. Given the slowdown in the global economy and potential coronavirus impacts, the sector could struggle to maintain February鈥檚 strong performance and may experience slower progress as we head into spring."聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽聽
