1. All Structures shall be weathering steel. 2. Fabricator to follow RUS Bulletin 1724E-204 “Guide Specification for Steel Single Pole and H-Frame Structures” (Latest Revision), ASCE 48-19 (or latest revision) Design of Steel Transmission Pole Structures or latest version, and American Welding Society (AWS), Structural Welding Code AWS D1.1 (Latest Revision). As well as any additional national, state, local codes and standards. 3. Toth and Associates to review vendor assembly drawings and calculations used for the design of each structure. Review of drawings and calculations does not relieve the vendor of responsibility for adequacy of the design, the correctness of the dimensions, details of the drawings and the proper fit up of all parts of the structure. Toth and Associates is responsible for providing loading requirements adequate for steel transmission pole structure design. 4. Attachment detail requirements will be submitted with geometric structure drawings. The vendor/fabricator will notify Toth and Associates of any attachment detail requirements that cannot be met or are of a conflicting nature. Any requirement not provided or that does not exist in ASCE 48 (latest revision) shall be at the Vendor's discretion. 5. Details herein are only typical of the shapes and dimensions desired. Fabricator may propose alternative connection for approval. 6. Ground Collars, on direct embedded structures shall have a minimum thickness of 3/16” and a length of 4’-0”. Locate collars on the centerline of the designated ground line. 7. For direct embedded structures, ‘CorroCote’ or equivalent coating shall be applied on the exposed surface from butt of the pole to the 2” below the top of the ground collar. The ‘CorroCote’ coating shall be feathered at the top edge to avoid water accumulation. 8. For foundation type structures, anchor bolt cages are to be designed and provided with the structures.
