A method of installing a plurality of carrier elements within a building structure. The method includes the steps of determining the intended locations of various carriers within the structure, formulating a record of such locations, assigning to each carrier a location code indicative of the record of the location points comprising its intended path within the structure, storing and retaining the record of the location information in an accessible memory means, such as in a written record or in the memory of a computer, and reproducing at least portions of the codes on portions of each of the carrier elements. The carrier elements are then installed in the structure such that each carrier element follows its intended path, and each carrier element bears a unique code referable to a record that discloses its location path within the structure. Access may therefore be had to the carrier element at some or all points along its length, and the identity of any one carrier element may be determined by reference to the code. In those cases wherein the record of location points does not uniquely identify the carrier element, a separate identifying code element may be used. The carrier may carry electrical or optical signals, or may comprise pneumatic, vacuum or hydraulic lines.
