There was 250,000 registered construction project contracts in Saudi Arabia before the first grace period to legalise expatriate workers ended on July 4.
However, 90,000 of these registered contracts, belonging to various small contracting companies have since been cancelled, the Arab News reported.
The newspaper quoted Raed Aqeili, a member of the National Committee in Saudi Chambers, as saying that most big projects were affected by the decision (to introduce Nitqat law) because they relied on small companies for employment.
As a result, a number of people from foreign countries who were working without valid work permits and runaways have come under the scanner.

Saudi Arabia has completed regularisation of nearly four million foreign workers in the last four months as part of its 'Nitaqat' programme, with 1.18 million expats choosing to change their profession.
Saudi King Abdullah bin Abdulaziz has extended the amnesty period for illegal foreign workers in the country by four months to November 4, bringing relief for thousands of immigrant workers, including Indians, who are yet to regularise their documents.
Aqeili feared the problem might escalate in the coming months, especially after the end of the grace period. He also said that contracting companies need to hire professional labourers from rental companies to carry on their work.
Once the grace period for workers without proper permits ends, all expatriates found in Saudi Arabia without valid papers will be jailed and heavily penalised.
