"As on December 1, 2014, a total of 731 projects were on the monitor of this Ministry.
"As per latest project implementation schedule, out of 731 central sector projects, 306 projects were behind schedule and of these, 27 projects were with cost overruns," Minister of State for Statistics and Programme Implementation V K Singh said in a written reply to the Rajya Sabha.
The ministry monitors central government's infrastructure projects costing Rs 150 crore and above with regard to timeliness and cost overruns.
Besides Central Sector Projects Coordination Committees have been set up in states under the chief secretaries for removal of bottlenecks and for facilitating the speedy implementation of major projects.
The nine-month old BJP led NDA government has committed that funds are no constraint for infrastructure projects.
Prime Minister Narendra Modi earlier this month has pushed for quick resolution of inter-departmental and Centre-state issues to speed up the pace of implementation of infrastructure projects.
