The unfinished Tyndall College in Carlow
Tyndall College and the Institute of Further Education in Carlow are now expected to be complete by the start of the summer.
Minister for Education, Joe McHugh, confirmed this week that the Carlow schools are among the last to be done.
Work halted on the schools in January of last year when the UK-based Carillion Construction - which had sub-contracted the works - went bust.
The Irish company, Sammon, had been sub-contracted by Carillion to carry out the building work on its behalf as part of the Public Private Partnership, but Sammon then went into liquidation in June of 2018.
This left six schools affected across the country and three of those have since been completed.
The school was due to be open for the start of this school year but that has now been pushed back to the 2019/2020 school year with many local contractors left out of pocket by the collapse of the two companies.
Minister McHugh said: "A replacement contractor was appointed in June 2018 and three of the six schools, Coláiste Raithín and Ravenswell Primary school in Bray and Loreto Secondary School in Wexford, have achieved service commencement and are now fully operational.
"The replacement contractor is now completing the remaining three school buildings in Carlow and Kells. While there has been slippage in relation to the completion dates originally targeted by the replacement contractor, work is progressing on all sites.
"The Public Private Partnership company has most recently indicated that they are targeting completion of all remaining buildings by Q2 of this year.
"However, the PPP company and contractor are currently working to finalise a detailed completion programme, which we expect to receive shortly."
