The six Tyndall College temporary prefabs are costing €185,000 as local contractors remain out of pocket for works done on the ill-fated Carlow school.
The additional temporary accommodation arrangements, alongside the existing building, is to cater for increased enrolments, according to the Department of Education.
Works came to a halt on Tyndall College last January 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.
In a statement, the Department confirmed that the cost of putting in place the temporary accommodation is approximately €185,000.
They added: "Including rental costs, technical consultant fees, submission for statutory planning consent, site preliminaries, civil works, mechanical & electrical works etc."
Many local contractors have been left out of pocket with one owed over €100,000 for works done previously telling Carlow Live he would go to jail over trying to get paid what he is owed.
The Department added: "The new school building for Tyndall College Carlow is one of six buildings being delivered via the Schools Bundle 5 PPP Project. Completion of the buildings was delayed following the liquidation of Carillion Construction Ltd earlier this year.
"The new building for Tyndall College is now targeted for completion by end December 2018."
Carlow/Kilkenny Education and Training board was granted planning permission on July 31 from Carlow County Council for the construction of six prefabricated temporary general classrooms and all associated site and development works.
Chairman of Kilkenny/Carlow Education and Training Board, Cllr Peter 'Chap' Cleere, said: "These will be provided by the middle/end of September.
"The students will have access to the existing adjacent Carlow Institute of Further Education Campus until the temporary classrooms are available in the next couple of weeks.
"KCETB will be catering for all students services from September. The needs of students, learners and staff are paramount to KCETB."
Cllr Cleere said that the Department of Education have confirmed to the ETB “that the interim works contract of the replacement contractor Woodvale, is now being extended to progress further works at the Carlow site, with a view to completion by the end of the year”.
Tyndall College is under the auspices of the KCETB.
He added that the new educational campus in Carlow will “facilitate and enhanced learning environment for students, learners and teaching staff providing top class modern facilities and enhanced space.”
