CERN engages numerous contractors to carry out work on the CERN site. These external companies must acquaint themselves with CERN’s complex governance and statutes, which dictate various aspects of their work from their tender to the end of the work on-site, and at every stage of the contract inbetween. A new version of the document that outlines the rules and conditions is now available.

In order to help contractors and technical managers who administer these contracts at CERN, a general document entitled “Working on the CERN site” (“Prestations sur le site du CERN” in French) was produced in the early 2010s. The goal was to make bidders and contractors aware of all the rules to which they are subject. A new version of this document is now at https://edms.cern.ch/ui/file/1155899/LAST_RELEASED/*.pdf

The revision of the document involved updating and clarifying many of its provisions, in particular those relating to safety, while keeping it concise and efficient. The new version also references more CERN rules and policies. Notably, it also contains new information on how to provide the authorities with data, and about the role of the radiation protection expert. 

Since this document brings together the statutory provisions applicable on the CERN site, it is subject to change over time. Contractors and technical managers of contracts at CERN must therefore consult it regularly and apply the most recent version (see link above).
