Investment in Ireland's energy, water and communications networks could create up to 20,000 trades and construction jobs, Fine Gael claimed today.
The party maintained putting money in key infrastructure projects through its NewERA stimulus plan was key to getting Ireland working.
Fine Gael said it was the only party to put forward a costed and credible plan to invest seven billion euro in modern national infrastructure.
Transport spokesman, Simon Coveney, revealed the bulk of investment would be ploughed into bringing energy, water and communications networks up to the best international standards.
"Fine Gael believes that NewERA, combined with our other jobs initiatives, can create 100,000 new jobs over the next five years," said Mr Coveney.
"Integral to that plan is the creation of at least 20,000 jobs directly in the trade and construction sectors though investment in key infrastructure projects."
The proposal was launched at St John's Central College, Cork, where party leader Enda Kenny met apprentices and post-Leaving Certificate course students.
It was claimed new jobs will be spread across the country in plumbing, electrical work and construction crafts; telecoms, civil and structural engineering; construction materials suppliers; plant maintenance and operation; insulation and home energy appliances; software programming and support; and construction professions such as architects and engineers.
Mr Coveney added: "Our NewERA investment plan will stimulate the construction sector and the wider economy in the face of the recession".
