The Government is expected to sign the controversial contract to extend broadband coverage to over 500,000 rural homes and business on Tuesday.
The Cabinet is meeting on Tuesday when Ministers will be asked to give the project the go-ahead, after which the contract is likely to be signed with National Broadband Ireland, the group led by the US businessman David McCourt.
The plan, which could cost the taxpayer as much as €3 billion in the coming years, has been subject to widespread criticism, both from outside and inside the Government.
Senior civil servants in the Department of Public Expenditure strongly opposed the plan on a value-for-money basis, but Ministers and officials in the Department of Communications took a different view and the Cabinet approved the plan in principle earlier this year.
Ministers have been summoned to a 7.30am meeting at Government Buildings to sign off on the plan, which has been strongly defended by the Taoiseach Leo Varadkar and Minister for Communications Richard Bruton.
The meeting follows legal drafting of the contract, and approval by the European Commission of the plan last week. It is expected that work on the first connections will begin within weeks.
The plan will provide high-speed fibre broadband to homes and businesses in areas - mostly remote parts of the country - which are not served by commercial operators. The contract will last for 25 years after which the operator will own the network. Last year The Irish Times revealed that the total cost of the contract to the taxpayer could be as high as €3 billion.
The Government is proceeding with the plan despite a recent vote in the Dáil calling for the contract to be renegotiated to ensure that the network was owned by the state, and not the commercial operator.
Opposition parties condemned the move, although some sources conceded unease at opposing such a high profile investment in rural Ireland. Fine Gael sources said they hoped the plan would be taken as a sign of the party’s commitment to rural Ireland.
“We have been clear and consistent in our criticism of how this Government has mishandled the rollout of broadband,” a Fianna Fáil spokesman said. “We will await the detail of what is being announced in this latest instalment before commenting further.”
Sinn Féin's David Cullinane said that the Government "should not proceed with a flawed and compromised process."
“Obviously we need to see a National Broadband Plan rolled out but not one that sees the state carry the risk and without owning the infrastructure at the end of the contract,” he said. The party favours re-examining the process with a view to asking the ESB to undertake the roll-out.
The Labour leader Brendan Howlin said that Fine Gael was "making an historic mistake signing the contract in its current form."
“Most worrying, the private owners will have the right to sell the network after just nine years,” Mr Howlin said.
“This approach is completely at odds with sensible economic decision making. A clear majority of the Dáil voted against this in support of Labour’s motion that the network should remain in public ownership.”
