The Construction (Design and Management) Regulations 2015 are effective from 6 April 2015 and replace the earlier CDM Regulations which were introduced in 2007.
The new regulations widen the scope of projects where parties have formal duties and shift the focus further to the design stage.
There is now a transitional period before the introduction of the new regulations for live-projects. Projects before April 2015 are subject to the CDM 2007 regulations until October 2015.
