Labelling and Identification. All hardware shall be uniquely labelled, and shall be linked to the appropriate element references as will be described in the Inspection and Maintenance Manual for the bridge. Cables shall be labelled at each end and at regular intervals. All labels shall be applied to the equipment before installation. All labelling shall be subject to the approval of the designer. Where appropriate and feasible, sensor axis alignment shall be marked onto the adjacent steelwork. Labels and markings shall be permanent, but shall not damage the structure or protective system (e.g. paint system or similar). All hardware shall be identified in the System Architecture Guide. Photographs shall be presented in the System Architecture Guide recording the position of each component of hardware, including the position and orientation of each sensor. Photographs shall be annotated with the appropriate labelling. The photographs shall be of sufficient quality and layout that it shall be possible to verify changes since installation.
