vehicles
road shoulder
saving of different existing materials from the projects which are removed and
intended to be used in other construction
salvage materials
written technical description of materials, equipment, construction systems, standards, and workmanship that, in conjunction with the drawings, detail the requirements for acceptable completion of the work
