The deepening downturn in India's crucial construction sector makes it understandable why Prime Minister Narendra Modi's image as the country's economic saviour has lost its lustre just over a year after his resounding election victory.
The decade-long construction boom in burgeoning cities like Noida, lured millions of labourers from the rural hinterland in search of a better life, creating one in every three new jobs.
That process is now going into reverse, undermining Modi's promise to create more employment for the one million Indians who join the workforce every month.
Indebted developers are cutting staff as they slow work on existing projects and postpone new buildings until they clear a backlog of 700,000 unsold homes.
A law to clamp down on "black money" flows that fund as much as a third of real estate deals is further squeezing demand.
Across the country, housing starts fell 40 % in the first half of the year, consultancy Knight Frank said. Cement output grew 0.9 % between April and June, down from 9.6 % a year earlier when Modi took office, government data show.
"The slowdown in the construction sector is very, very depressing which will have a negative impact on the overall GDP growth numbers in the first quarter of the current fiscal year," said Samantak Das, chief economist at Knight Frank India.
Rating agency Moody's last week cut India's growth forecast to 7 % for this fiscal year, against the government's target of 8 to 8.5 %.
India releases its GDP figures for the April-June quarter on Monday.
The lack of jobs is already being felt in Bihar, the source of the many labourers toiling near Delhi.
In Patna, eight out of 20 labourers contacted by Reuters had this year made the 1,000 kilometre (600 mile) trip back from Delhi because they could not find work - pressuring salaries in a region where wages are already low.
According to brokerage Ambit Capital, rural wages may now be falling after growing 4 % in the year to March - a far cry from the double-digit annual rises between 2010 and 2014.
"Labourers are starving and are ready to work even at lower wages as there are fewer or just no jobs in the construction markets," said Navendu Kumar Thakur, Patna chairman of the Builders Association of India.
The squeeze comes at a bad time for Modi.
Bihar heads to the polls this year, in an election where the Bharatiya Janata Party (BJP) must win to gain seats in the upper house of parliament where Modi lacks a majority to pass economic reforms.
Economists say that lower interest rates and a government splurge on infrastructure should eventually help revive construction, which contributes a tenth of the GDP.
BJP also wants to regulate property markets and tie investor money to specific projects to stop developers diverting cash elsewhere.
The slowdown around Delhi, where unsold inventory is highest, shows no sign of abating, however.
Noida, a city of 640,000, has grown rapidly in the last decade, expanding to a point where its middle-class housing complexes now meld into Delhi's urban sprawl on one side and villages on the other.
Real estate association CREDAI's Rohit Raj Modi estimates construction in Noida employed more than a million labourers at its peak in 2013, at least double today's number.
Even when the market recovers, a shift to mechanisation on larger sites would limit demand for new workers.
"From a labour point of view, the peak is over," he said.
