This note is written to assist permanent works designers (PWD) in their legal obligations in relation to temporary works, stemming from CDM2015, and also to demonstrate the wider project benefits of careful consideration.It will also be of use to Principal Designers (most projects will have one of these appointed) and to Clients, informing them of what should be expected of PWDs on their projects.Temporary works cover a wide field of activity: these are illustrated in Appendix B and C of the TWf ‘Client’s Guide to temporary works’.Note that the definition of temporary works adopted by TWf includes interim states of the permanent works and the loading of the permanent works by temporary construction loads.#pwd#temporaryworks#cdm2015
