Construction Industry Federation (CIF) boss and former TD Tom Parlon claimed over €295,000 in expenses during the four-and-a-half years he was a junior minister at the Office of Public Works (OPW).
Parlon claimed a massive €82,495 in travel and subsistence during 2006 alone.
This compares to a total of €28,526 which his two successors in the post of minister of state at the OPW, Noel Ahern and Martin Mansergh, claimed between them for 2008.
In the five months between January and May 2007, when he lost his Dáil seat, Parlon also claimed a total of €41,381, the figures show.
In 2005, he claimed €67,941. During the previous year, he received €40,086 in expenses. And in 2003, he claimed €64,022.
Overall, this brings the cost of his expenses to €295,927 for the four-and-a-half years in question.
Around €228,000 of these are listed under the category of "travel", with a further €57,395 listed as "payments to the Department of Foreign Affairs for travel and subsistence costs".
The remainder are listed as "subsistence" payments. Parlon, who is understood to be abroad on annual leave, was unavailable to comment when contacted by this newspaper.
During his time at the OPW, he oversaw the government's much criticised decentralisation programme.
But within months of losing his seat, he controversially transferred to the CIF on a rumoured salary of €250,000, where his role is to represent the interests of the construction sector.
A spokesman for the OPW was unable to respond to a series of questions in relation to the expenses in advance of publication.
However, Fine Gael TD George Lee, who obtained the figures in a written reply to a Dáil question, called for an explanation to be provided as to why the expenses claimed by Parlon were so high.
"The problem is not having any explanation in relation to how or why these bills were run up," he said. "I can understand how people might look at them as a gravy train. And you can't blame people for interpreting them in this way."
Lee, who has asked each department to provide details of the amount claimed in expenses by each senior and junior minister between 1997 and 2008, said another striking aspect of the responses he has received to date was the differences in the amounts involved.
"When you look at the range of figures we're getting, you have to wonder: what is the story?" Lee said. "Did different people have different attitudes to expenses? And can they literally run up any expense they want?"
Figures previously released by Lee show current education minister Batt O'Keeffe claimed expenses of more than €205,000 during his four years as a minister of state at the Department of the Environment.
But the figures provided to him for John O'Donoghue TD, who last week resigned his post as Ceann Comhairle after a series of revelations in the Sunday Tribune about his spending on foreign travel, amounted to just over €16,000 during his time as minister for arts, sport and tourism.
This is despite the fact O'Donoghue ran up an expense bill of more than €550,000, according to information released to this newspaper under the Freedom of Information Act.
