CDM 2015 – Multi-Site Arrangements


The CDM challenge for the Crossrail project was to maintain a consistent approach to CDM compliance on more than 40 diverse projects. These were spread over a wide geographic area and consisted of challenging projects and work sites varying from green field sites to tunnelling under central London to new build facilities. This case study will explain how Crossrail, as Client and Principal Designer, discharged its CDM duties through the use of a CDM Integrator; managing the defined activities undertaken by a wide range of Crossrail post holders, providing assurance that compliance with CDM was maintained. This was all undertaken in-house by competent resources, using defined processes and procedures that were managed by Project Managers and Health and Safety Advisors with guidance from the CDM Integrator. These all worked closely with Principal Contractors, who integrated the Crossrail process and procedure into their own management systems. Consistent verification of compliance with the CDM procedures and processes assisted in ensuring compliance with the CDM duties and was aided by constructive feedback and suggestions from the Designers and Principal Contractors as to how to improve and develop the processes. This case study will be of use to Clients and Principal Designers on similar multi site construction projects wanting to ensure legal compliance with their CDM duties define expectations, and the means by which they are defined, managed, monitored and shared.
