Two thirds of high-rises are finished late and almost a fifth are more than six months behind schedule, according to the latest research from the Chartered Institute of Building (CIOB).

Announcing the results of the poll of 73 companies covering over 2,000 projects, incoming CIOB president Keith Pickavance blamed poor time management practices for the industry's bad record for delays.

Complex projects like hospitals, prisons, stadiums, railways stations, he said, were generally delayed much more than simpler ones including low-rises, schools, industrial, housing, schools and education buildings.

Building magazine reported the findings, which also show that about half of the engineering projects examined were not finished by the completion date, with 18% over six months late and a third finishing on time. High-rise buildings performed very poorly, with a fifth completed over six months late and a third finishing on time.

Among the CIOB's conclusions was the need to increase use of critical path network software tools on projects, plus better provision of facilities for training and accrediting planning engineers and project schedulers in time management techniques.

The next issue of CM features an interview with Pickavance and an indepth look at the time management survey results.
