The Government today sought builders for multi-million euro contracts to construct decentralised offices for a total of 720 staff in Dungarvan, Edenderry, Roscommon and Tipperary.
Up to 190 staff of the Irish Naturalisation and Immigration Service within the Justice Department are to move to Tipperary town.
A total of 230 employees in the Land Registry staff will relocate to Roscommon.
Approximately 200 staff of Ordnance Survey Ireland will move to Dungarvan while 100 workers in FETAC, HETAC and the National Qualifications Authority of Ireland (NQAI) are decentralised to Edenderry.
The Office of Public Works (OPW) is seeking applicants to design and build the facilities, beginning in 2007.
The first Government department to have completed its move under the Decentralisation Programme opened its new offices in Tullamore last week.
Almost 130 Finance Department civil servants relocated from the capital to the Midlands town under the scheme.
More than 2,000 Government workers will relocate to 29 locations across the country by the end of 2007. Decentralisation has already been earmarked for 12 different towns under the project announced by former Finance Minster Charlie McCreevy in 2003.
