Revision of the Diversionary Works Code of Practice, ‘Measures necessary where Apparatus is affected by Major Works (Diversionary Works)’, published in 1992, has been “on hold” for some time awaiting a decision by the Department for Transport on whether the current legal ruling on the issue of charging for estimates reflects the original intention of the legislation. Nevertheless, in recent years, the Diversionary Works Working Group (DWWG) has been convened to review issues of concern to practitioners and to disseminate advice so that improvements in understanding and working practices can be achieved.
