A number of Government minsters have expressed doubts over whether the construction sector will be able to return as planned next month.
The Department of Housing is keen to see a return of home and apartment building after March 5th, with commercial construction to return at a later date.
However, privately some ministers think NPHET is likely to advise against it and that the wider construction sector may not return until April.
One Cabinet source said they believe NPHET will prioritse opening schools in March, with housing waiting another month.
A senior source in the Department of Housing said they will present NPHET with evidence showing the limited amount of construction that has stayed open through live five has done so safely.
The Government estimates each week the sector is shut translates to 700 or 800 fewer houses that will be built this year.
On today's Newstalk Breakfast, Housing Minister Darragh O'Brien said March 5th is still the target date for construction to resume.
He said there'll be a review next week, and the final decision will be one made by all of Government.
He said: "The construction sector has operated very safely, and the reason they were closed was not because of anything they were or were not doing - it was simply around reducing the movement of people.
"I earnestly want and the Government earnestly wants the sector to open safely as soon as we possibly can."
