About this file
The document is a Section 58 Highway Signing specification from a transportation department, detailing technical requirements for roadway sign installation and procurement. The specification covers the furnishing and erection of aluminum or steel roadway signs with supporting posts or columns, including both roadside and overhead sign installations. Sign types range from single-post and multi-post assemblies to overhead truss, cantilever, and bridge-mounted signs, with provisions for both standard and lighted sign configurations. The specification provides comprehensive guidelines for sign panel materials, support structures, preparation, and installation, with detailed measurement and payment methodologies for various sign assembly types and sizes.
The pricing structure is itemized through multiple pay item categories (A700 series) with granular classifications based on sign panel square footage, structure length, and specific installation requirements. Payment covers complete sign assemblies including panels, supports, foundations, and for lighted signs, electrical installations up to connection points. The specification allows contractors flexibility in material selection between aluminum and galvanized steel for certain components, with specific restrictions on frangible supports requiring aluminum. Electrical components like conduit, conductors, and service point equipment are explicitly noted as not being included in the base sign installation pricing, providing clear delineation of contractor responsibilities and potential additional costs.
