There are fears there will be further delays to the opening of the new National Children's Hospital due to a rift between BAM and the board.
A further 'breakdown' in communications over the project could lead to the current completion date 'slipping further'.
The Irish Times reports there's been another rift between the contractors 'BAM' and the development board, with the contractors reportedly refusing to meet with its members.
While it's also been reported a company hired to review the progress of works on the site were 'shut out' for six weeks.
A construction spokesperson for BAM told the paper it 'has fully engaged with the board, and will continue to do so'.
It comes as the Oireachtas Health Committee heard last week, that just 27 of 300 hospital rooms have been completed at the new hospital, on the grounds of St.James' Hospital in Dublin.
BAM's most recent progress report predicts the hospital will be complete by May 2024, 21 months behind schedule.
