The emergency accommodation site in Gormanston Camp in County Meath will be closed next month, as winter conditions set in.
The site, which is currently housing 190 people, opened in July to house new arrivals fleeing war.
The accommodation facilities at Gormanston Military camp will close in the first week of October, as it was never intended to remain during colder winter months.
About 800 new spaces are needed each week, however, as anything between 90 and 130 people arrive from Ukrain in Ireland each day.
The vast majority need state accommodation, unlike earlier in the crisis when many arriving already had friends and family in the country.
37,800 Ukrainian refugees living in state accommodations - with the vast majority living in serviced accommodations - like hotels and student apartments.
However, 165 contracts with providers are expected to run out in December - and the Department of Equality is working to renew those if necessary.
It expects almost 60,000 people to have arrived here by the end of the year and they say it's their aim to move away from serviced accommodation and into more private homes and pledges.
