A method of building a structure, the method including the steps of: 1. fabricating a generally longitudinal, steel sub-structure of the structure with a cable retainer attached to, or forming part of, the substructure and that extends substantially longitudinally therealong; 2. assembling the sub-structure into a structure; 3. inserting a cable into the cable retainer; 4. after step 2, applying a tensile force to the cable relative to the cable retainer; and 5. after step 4, bonding the cable to the cable retainer.
