The Oireachtas Health Committee has heard the contractor behind the development of the Children's Hospital hasn't provided a progress report in four months.
Revelations from the hospital's board this morning also described deficits in productivity from BAM, with just 27 out of a target of 3-thousand rooms deemed complete.
Meanwhile, BAM has also submitted over 2-thousand costs claims totalling 756 million euro, which were described as "grossly inflated".
Fianna Fail TD John Lahart says there are questions over BAM's performance in the hospital's construction:
"If this was a contractor on a school, or a contractor on a house and uou had questions about the productivity rate being low, about progress reports not being provided for four months, you'd call it and say 'who could give this company any contract' in the future."
