A NEW Casement Park could be built by 2019 "with a fair wind", a senior GAA official has said.
Announcing a new public consultation on the £70m project in west Belfast, Tom Daly, chairman of the Casement Park Project Board, said the GAA remains firmly committed to a new stadium.
"If things happen within reasonable time frames we hope for a 2019 completion date, but everything has to fall into place," he said.
Plans to redevelop Casement Park have been hit by a series of problems.
The GAA was just four days away from beginning work on previous plans when a legal challenge was launched.
In 2014 the High Court then quashed a decision to grant planning permission.
Concerns have been raised by residents about the height and capacity of the stadium and how it could be evacuated safely in an emergency.
Around £6m has already been spent on the project, including legal fees.
Now the GAA is to begin a completely new 20-week consultation process.
Mr Daly said it will look at all aspects of a new Casement, including its capacity and safety.
He said the public will be asked to make suggestions about the stadium and uses for its proposed community space during events at Conway Mill, Andersonstown Leisure Centre and Glen Community Complex on May 24, 25 and 26.
The GAA will hold events across Ulster and people will also be able to give suggestions online.
The association will then draw up plans by late summer or autumn of this year.
"We know clearly there are people who had reservations about the project as it was proposed before," Mr Daly said.
"The critical thing is that we want to get the optimum design for the site. We're approaching this in a very positive frame of mind. We do want everyone to lend their voice."
When asked whether the new stadium will have 38,000 seats as previously planned, he said it must have a "significant capacity" to handle provincial fixtures but no figure had been discussed.
"It will be later in the process before we start talking about numbers," he said.
"Otherwise you're really predetermining things before you've heard all the voices and you really don't want to do that. We do want to listen."
Last year safety expert Paul Scott raised concerns that the planned stadium could not be evacuated safely in the event of an emergency.
Mr Daly said discussions about safe operation had already begun before the new plans are drawn up.
"This time we are engaging in the operational side of it earlier than other stadia providers have had to do," he said.
"That process is moving forward in a positive way."
He added that the GAA had an "excellent safety record and we don't intend to compromise on it".
Mr Daly said other stadia were able to operate safely in busy residential areas.
"The thing about emergency exiting is there are obviously very sophisticated protocols that are operated," he said.
"There are many examples of stadia in Ireland and Britain and throughout Europe where there are site challenges. The other two stadia in Belfast are in built-up areas too and certain challenges come with that."
He said the GAA is firmly committed to a new Casement Park.
"Croke Park has never demurred in its commitment despite the fact that this hasn't been an easy pathway," he said.
He added: "We've a very strong professional team in terms of the consultants involved. We don't intend in leaving any stone unturned in relation to the process."
