(A) Epoxy attachments shall not be used. Epoxy compounds can lose strength at temperatures exceeding 140°F. Additionally, epoxy compounds can subjected to extreme stresses from thermal expansion/contraction of the metal structure due to changes in the ambient temperature and subsequently exhibit shear failure.
(B) Stud welding shall not be used. A properly installed stud weld will scorch the internal coating system in the same manner as ordinary stick welding. In addition, the plate attachment to the studs is open to water seepage and corrosion from trapped water and moisture. Proper coating procedures cannot be used on tank surfaces that have plates or other attachments bolted to them.
(C) Any penetrations larger than 3 inches in diameter that are to be cut into the support structure require special expertise in design and installation to minimize the possibility of structural damage to the structure. Consideration should be given to reducing the tank water level whenever openings are cut into the support structure. A professionally engineered solution must be provided.
(D) Antenna cables should be arranged and located to allow protective wrapping during abrasive blasting and recoating. Neatly arranged cables shall be offset from the tank to allow maintenance contractors to perform this work without removing the cable runs. Chaining or strapping to tower legs or handrails is not allowed. Cable runs should be routed under balconies or walkways to minimize access interference. Vertical coax routing up a leg should be orientated towards the center of the tank on the inside face of the leg where possible.
(E) The first carrier on the tank shall use hinged cluster brackets with snap-in clips capable of supporting eighteen 1 and 5/8-inch coax cables, and shall route the coax cables on the inside of the cluster brackets.
(F) Cables and antenna shall be installed with a minimum of 6-inch offsets. Any deviations must be expressly approved by the Town of Wilkesboro.
(G) Coax runs shall have a minimum of 4 feet clearance from tank logos.
(H) Penetrations shall be designed in accordance with AWWA § 3.13.
(I) Penetrations through walkways and platforms shall be toe board compliant in accordance with OSHA regulations.
(J) All installers shall comply with applicable local, state and federal requirements. In the absence of any applicable government standards, applicable BOCA and NEC codes, as well as EIA, TIA and AWWA, standards will apply.
(K) All materials and workmanship are to be in compliance with the latest AWWA codes and regulations.
