Self Supporting Tower Ft. Pierce Interchange Site Our Job No. 17-165 AUTHORIZATION In accordance with your instructions, Pate Engineering has inspected the 220-Ft. self supporting tower located at the Ft. Pierce Interchange site, Milemarker 152, Florida Turnpike, Port St. Lucie, St. Lucie County, Florida. INTRODUCTION The structure is a three -leg, 220-ft. self-supporting tower manufactured by PIROD, Inc. The inspection included the installation work of the tower modifications, the new antennas, lights and cameras for the following project: "Florida's Turnpike Enterprise Towers, Refurbishment And Repairs Project". The information concerning this tower work was provided by the Florida Department of Transportation. The information included the project drawings Appendix A, the revised Tower Loading Diagram and some of the project submitted documents approved by FDOT. The inspection also included the tower modification drawings. Pate engineering designed the modifications under Job No. 17-165. The Drawings No. FP-1, FP-2, FP-3 and FP-4, dated 5/8/18 were issued for the project. The Drawing No. FP-1 is attached for reference. Pate Engineering visited the site on November 16, 2021, to visually inspect the tower work. Photographs of the tower taken by the climber and taken from the ground are attached for reference. The photographs taken by the climber and his comments were carefully reviewed. INSPECTION CRITERIA The tower was visually inspected for general compliance with the provided drawings and documents, and different tools and equipment were used for this purpose. The inspection was mainly to verify modifications, and new antenna and equipment installation. To: FDOT Re: Our Job No. 17-165 The tower was inspected with the assistance of a professional climber under the direction of Pate Engineering. The climber was provided by FDOT and carefully selected for this specific inspection. The climber used two of the tower latticed legs to climb the tower, to access the equipment and the antenna locations. RESULTS OF THE INSPECTION Tower Modifications 1.1 The new diagonal members between the 180-ft. and 190-ft. levels were inspected. The member sizes and connection details were verified. The installation was according the previously described Pate Engineering drawings. See Drawing FP-1. 1.2 The new diagonal members between the 20-ft. and 40-ft. levels were inspected. The member sizes and connection details were verified. The installation was according the previously described Pate Engineering drawings. See Drawing FP-1. 1.3 The new leg splice bolts at the 20-ft. level were inspected. The bolt sizes and installation details were verified. The installation was according the previously described Pate Engineering drawings. See Drawing FP-1. Antenna Installation 2.1 The approximate mounting heights for the new antennas and equipment were verified. There were some approved changes during the installation of the new antennas. The final antenna elevations are listed below. See photographs, sheet No. 1. Antenna Description Elev. As Installed 8-ft. HP Dish 215' (2) ASP705K 212' 8-ft. HP Dish 207' 8-ft. HP Dish 185' 8-ft. HP Dish 177' 2.2 The two 8-ft. HP dish antenna installations on leg A (28 deg. Leg) were inspected. These antennas are located at the 215-ft. and 185-ft. levels. The inspection included antenna mounts, hardware, connections and side struts. The antenna installations were adequate and consistent with the previously described documents for the antennas, except that one of the outboard side struts was not installed. This was accepted, we understood, during the project review process to avoid the addition of several supporting members. Those member would increase the wind loads. See photographs, sheet No. 2, 4, and 10. 2.3 The two 8-ft. HP dish antenna installations on leg 8 (148 deg. Leg) were inspected. These antennas are located at the 207-ft. and 177-ft. levels. The inspection included antenna mounts, hardware, connections and side struts. The antenna installations were adequate and consistent with the previously described documents for the antennas. See photographs, sheet No. 3, 4, and 11. I To: FDOT Re: Our Job No. 17-165 2.4 The two ASP705K antenna installations were inspected. These antennas are located at the 212-ft. level and they were originally leg mounted at the 219-ft. level. The antennas were installed on 6-ft. side arms with stiff arms, this is a change to the original scope of work. The inspection included antenna mounts, hardware, connections and stiff arms. The antenna and the standoff installations were adequate. See photographs, sheet No. 1. 2.5 Two pieces of steel cable and an empty can (soda) were abandoned at the top of the tower, at the dish antenna locations. See photographs, sheet No. 5. 2.6 The antenna transmission lines installations were inspected. The inspection included hangers and support brackets. The installations in general were adequate and consistent with the previously described documents. However, one hanger at the 207-ft. level is not connected. See photographs, sheet No. 6. Camera Installation 3.1 The two camera installations were inspected. These cameras are located at the 96-ft. level. The inspection included camera mounts, hardware, connections, lowering boxes and lowering post. The cameras installations were adequate and consistent with the previously described documents. However, the eye bolt for the lowering wire of the camera on leg C (268 deg.) was installed on the fence corner post. The other camera has the eye bolt installed on a new pole, as required. See photographs, sheet No. 7. Obstruction Lighting System 4.1 The obstruction lighting system installation was inspected. The inspection included the top light and the side markers. The installations were adequate and consistent with the previously described documents. See photographs, sheet No. 8. 4.2 The old side markers located below the new markers were removed. However, some of the steel parts were abandoned on the tower. See photographs, sheet No. 8. Safety Climb System 5.1 The safety climb system installation was inspected. The inspection included top and bottom mounts, hardware, connections, cable and cable guides. The installation was not adequate, some of the intermediate brackets are not connected and the cable is unsupported at those locations. See photographs, sheet No. 9. 5.2 The safety cable at the 162-ft. level is in front of a pipe member (stiff arm) from the sector mounts. The cable is continuously moving (rubbing) and future cable damage can be anticipated. See photographs, sheet No. 9. To: FDOT Re: Our Job No. 17-165 RECOMMENDATIONS 6.1 The final antenna elevations and mounting system described in 2.1 and 2.2 need to be reviewed by FDOT, and compared with the approved changes. Pate Engineering participated only partially during the final review process. 6.2 The antennas described in 2.4 were installed on side arms and at a lower elevation. It is assumed that this change was approved during the review process. 6.3 The abandoned items described in 2.5 need to be removed from the tower, 6.4 The transmission line hanger described in 2.6 needs to be properly installed. Any other similar hanger condition needs to be corrected, the inspection didn't cover every new hanger installed on the tower. 6.5 The location of the eye bolt described in 3.1 needs to be reviewed by FDOT, and compared with the approved changes. Pate Engineering participated only partially during the review process. 6.6 The abandoned items described in 4.2 need to be removed from the tower. 6.7 The safety climb system needs to be properly re -installed. The conditions described in 5.1 and 5.2 need to be corrected. The safety cable needs to be properly supported and any possibility of cable damage should be avoided. 6.8 To the best of my knowledge, information and belief, the antennas and equipment described as adequate have been installed in substantial compliance with the previously described documents approved by FDOT. 6.9 The antennas and equipment, in general, should be inspected for maintenance purposes on a routine basis and after severe weather conditions.
