The Utah Department of Transportation (UDOT) has thousands of poles that are used to mount vehicle detection sensors, CCTV cameras, etc. at adequate heights. Maintenance technicians use bucket trucks to access the devices to install, maintain, or replace them. There are locations where bucket truck access is difficult. UDOT is interested in 40 ft - 60 ft poles or towers that hinge and allow a maintenance technician to access devices near or at the top of the pole while standing on the ground. 2.0 References 2.1 AASHTO “LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals,” Current Edition with all applicable interim revisions. 2.2 American Society for Testing and Materials (ASTM) 2.3 American Welding Society (AWS) D1.1 Structural Welding Code. Current Edition. 3.0 Pole/Tower 3.1 Various heights shall be provided between 40 and 60 ft. 3.2 Cable shall be covered until reaching the device without the need to add components. 4.0 Hinge/Tilt Point 4.1 The pole/tower shall not use any mechanical or electrical components to hinge/tilt. (base: we require a precast or manufactured foundation, so we don't have to worry about the pole/base connection point). 4.2 The pole/tower shall allow for bi-directional lowering. 4.3 The electrical cables shall be protected at the hinge/tilt point. 4.4 Pole/tower shall not require more than one user to lower the tilt pole. 5.0 Materials 5.1 Steel: ASTM A500 GR B or ASTM A501 GR B or greater tensile/ strength 5.2 Structure Finish: ASTM A123 or AASHTO M111 5.3 Flexible conduit must have UV resistance/protection 5.4 Welds: Meet minimum current AWS D1.1 weld testing requirements
