Called The Improving Performance of the UK Construction Industry,* the report will be launched by construction minister Nick Raynsford on Monday.
It says clients are 16% more satisfied with main contractors' performance since 1995 and 10% more satisfied with consultant teams' performance than they were in 1995. However, it adds that the industry still has some way to go.
It points to some areas where the industry can improve, including time and cost overruns.
These were criticised in a study by the Construction Clients' Forum that was the basis for the report. It showed that 58% of clients' projects were late and that 32% of work was over budget. It also said 30% of work was delayed by defects and that construction work ran 53 days behind schedule on average.
Several other events are planned for the five days of National Construction Week.
On Tuesday, environment day, the Construction Confederation is set to announce the creation of a group of industry leaders to promote green awareness in the industry.
The idea for the group was hatched at last month's confederation conference, for which Building was co-sponsor.
The group will try to encourage contractors to take measures to help the environment and distribute literature about the initiative.
Twelve construction companies will also open their doors to others wishing to learn from them.
Galliford, Wates, housebuilder Westbury, QS Bucknall Austin, M&E contractor Crown House and engineers Oscar Faber and Ove Arup will take part in this venture, which is being organised by the Confederation of British Industry, Inside UK Enterprise and overall week organiser the Construction Industry Board.
