Remove the bolted connections at the upper level of steel angle X-bracing that is bowing and buckled at the north bracing elevation.The out-of-plane buckling may be caused if the bolt holes in the angle bracing are not spaced at the same distance as the bolt holes between the connection plates.The out-of-plane bracing will not engage in tension without considerable deflection of the tower structure;therefore,the angle bracing shall be straightened and reconnected by welding to the connection plates with continuous 1/4"fillet welds on the top and bottom at each end of the steel angles.The bolt holes shall not be enlarged to straighten the angle bracing because special slip-critical bolts would be required. 3. The replacement of the aerator tower protective coating system should be considered a High Priority at the Ridgecrest WTP.Based on the observed steel corrosion and condition of the existing paint coating,K I W recommends a new long-term high performance coating system for all exposed KIW Structural Engineers K I W Project: 21244 January 14, 2022 Page 5 of 27 structural steel surfaces of the entire aerator tower. See Appendix B for surface preparation and coating system recommendations. 4. The members noted with moderate surface corrosion did not appear to have deteriorated to the extent requiring reinforcement or replacement; however, the amount of section loss cannot be accurately measured until the corrosion has been removed and steel has been properly cleaned. K I W should re-evaluate any portions of steel with section loss that appears greater than 10%after the recommended surface preparation described in Appendix B is completed. 5. If K I W determines the section loss of a structural steel member is not acceptable,the member can either be replaced by matching the original construction with new materials or the member can be reinforced with supplemental steel. It is important the supplemental steel does not create additional surfaces for water to accumulate. For a round pipe member, continuous steel angles can be welded to the existing round pipe as shown in Figure A below. For steel beams, continuous steel plates can be welded to the flanges of the existing steel beam as shown in Figure B.The size and thickness of the supplemental steel reinforcement will be determined based on extent of section loss. For the platform beam framing, the bottom beam flange is accessible to install the supplemental steel plate; however, it should be noted the aerator tower legs will conflict with the installation of a continuous steel top plate. Installing segmented steel plates between the aerator equipment legs is not feasible because the capacity of the steel beam will not be restored at the separation joints. If the platform beam top flange requires steel plate reinforcement,temporary shoring and removal of the aerator tower legs will be required until the installation of the supplemental steel top plate is complete.Welds with significant section loss shall be restored to a 1/4"thickness after cleaning.Significantly deteriorated steel angle bracing should be replaced with a member of identical size and thickness. to STEEL ANGLE REINFORCEMENT 1/4" L EXISTING 1/4" STEEL BEAM ^‘ EXISTING SEAL 1/4" L 110 ROUND PIPE STEEL PLATE 1/4" r IP REINFORCEMENT AS REQUIRED TO AVOID OVERHEAD WELDING w FIGURE A FIGURE B Based on recent information obtained from material suppliers, pricing data for similar work, and correspondence with high-performance coating technical consultants, K I W estimates the probable cost of the above recommended actions for the Ridgecrest WTP aerator tower will be approximately$39,000.00.

It is our understanding the aerator tower was recently constructed in 2018. The aerator tower consists of(4) 12"x12"square tube columns spaced in a 19'-6"square grid.The columns are braced with an intermediate horizontal steel wide flange beam and two levels of 4"x4" square steel tube X-bracing.

Mild to moderate corrosion was observed in the interior of all of the steel tube X-bracing. Each end of the steel tubes was open and was not covered with closure plates.The exposed interior surface of the steel tube X-bracing was not protected with any coating, primer, or galvanizing. v_i_ 1 I _ _= i- - - - II:, --- V li KIW Structural Engineers K I W Project: 21244 January 14, 2022 Page 15 of 27 2. The ends of several of the steel tube X-bracing members were misaligned with the connection plate and were only in partial contact with asymmetrical welds.The bolt holes that are misaligned were likely intended for erection purposes only. It appears an additional erection bolt was drilled into the connection plate and end of the steel tube to facilitate the steel erection.The welds attaching the ends of the steel tubes to the connection plates likely provide the structural connection. • • 3. The majority of the protective paint coating appeared to be in excellent condition;however,there were a few areas that appeared to have an insufficient thickness of the topcoat with a speckled portion of the base coat or primer exposed. to r .. :rAlm KIW recommends the following actions for the aerator tower at Meadowbrook Water Treatment Plant #1101: 1. The open end at the top of each of the steel tube X-bracing members should be sealed with a steel closure plate to prevent water intrusion from rain or condensation from the aerator equipment. It is not recommended to seal the bottom of the steel tubes because this could trap any moisture infiltration inside the steel tube. It is likely not feasible to apply a coating to protect the exposed interior face of the steel tubes;therefore,it should be anticipated that the interior face of the steel tubes will continue to slowly corrode due to exposure to humidity.Sealing the top of the steel tube bracing will mitigate the corrosion rate since it will prevent most of the rainwater infiltration. K I W recommends that CCUA avoid the use of similar steel tube X-bracing members for any new aerator tower construction or other exposed exterior structures. KIW Structural Engineers K I W Project: 21244 January 14, 2022 Page 16 of 27 2. CCUA should request the original engineer-of-record review and approve of the corrections and asymmetrical welds at the misaligned steel tube X-bracing connections unless the corrections were performed under the supervision of the engineer during construction. 3. CCUA should regularly maintain and touch-up any portions of the protective paint coating if the primer, base coat, or minor surface corrosion is observed. 4. The full replacement of the aerator tower protective coating system is not currently required. Based on pricing data for similar work,KI W estimates the probable cost of the above recommended action to seal the top of the steel tube X-bracing at the Meadowbrook WTP aerator tower will be approximately $9,500.00. t0 KIW Structural Engineers K I W Project: 21244 January 14, 2022 Page 17 of 27 Spencer's Crossing Water Treatment Plant#1114 The aerator tower at Spencer's Crossing Water Treatment Plant (WTP) is located at 4426 Hanging Moss Drive in Orange Park, FL.The aerator tower consists of(4) round pipe columns with an outside diameter of 8.5 inches and spaced in a 15'-0"square grid.The columns are braced with an intermediate horizontal steel channel and two levels of L2X2 steel angle X-bracing.

Despite some signs of adhesion failure, paint delamination, and surface corrosion, the full replacement of the aerator tower protective coating system may be considered a Low Priority at Spencer's Crossing WTP. 3. Isolated repairs and limited replacement of the protective coating should be performed at the members indicated with adhesion failure, paint delamination, and surface corrosion, Repair procedures and coating materials should match those recently used at the base of the steel pipe columns or the surfaces should be prepared and coated per the recommendations in Appendix B. 4. CCUA should regularly maintain and touch-up any portions of the protective paint coating if the primer, base coat, or minor surface corrosion is observed. 5. The members noted with minor surface corrosion did not appear to have deteriorated to the extent requiring reinforcement or replacement; however, the amount of section loss cannot be accurately measured until the corrosion has been removed and steel has been properly cleaned. K I W should re-evaluate any portions of steel with section loss that appears greater than 10%after the recommended surface preparation described in Appendix B is completed. 6. If K I W determines the section loss of a structural steel member is not acceptable,the member can either be replaced by matching the original construction with new materials or the member can be reinforced with supplemental steel. It is important the supplemental steel does not create to additional surfaces for water to accumulate. For a round pipe member, continuous steel angles can be welded to the existing round pipe as shown in Figure A. For steel beams, continuous steel plates can be welded to the flanges of the existing steel beam as shown in Figure B.The size and thickness of the supplemental steel reinforcement will be determined based on extent of section loss. For the platform beam framing, the bottom beam flange is accessible to install the supplemental steel plate; however, it should be noted the aerator tower legs will conflict with the installation of a continuous steel top plate. Installing segmented steel plates between the aerator equipment legs is not feasible because the capacity of the steel beam will not be restored at the separation joints. If the platform beam top flange requires steel plate reinforcement,temporary shoring and removal of the aerator tower legs will be required until the installation of the supplemental steel top plate is complete.Welds with significant section loss shall be restored to a 1/4" thickness after cleaning.

Y I t sf,e 40,K. ,c;A K I W recommends the following actions for the aerator tower at Ravines Water Treatment Plant#1115: 1. The open end at the top of each of the steel tube X-bracing members should be sealed with a steel closure plate to prevent water intrusion from rain or condensation from the aerator equipment. It is not recommended to seal the bottom of the steel tubes because this could trap any moisture infiltration inside the steel tube. It is likely not feasible to apply a coating to protect the exposed interior face of the steel tubes;therefore,it should be anticipated that the interior face of the steel tubes will continue to slowly corrode due to exposure to humidity.Sealing the top of the steel tube bracing will mitigate the corrosion rate since it will prevent most of the rainwater infiltration. K I W recommends that CCUA avoid the use of similar steel tube X-bracing members for any new aerator tower construction or other exposed exterior structures. 2. CCUA should regularly maintain and touch-up any portions of the protective paint coating if the primer, base coat, or minor surface corrosion is observed. 3. The full replacement of the aerator tower protective coating system is not currently required. KIW Structural Engineers K I W Project: 21244 January 14, 2022 Page 25 of 27 4. It is our understanding the old aerator tower located to the east of the relatively new aerator tower is abandoned and not in service;therefore,a review of the abandoned aerator tower was excluded from this report. If this steel tower is to be utilized at another water treatment plant,the structure will require significant repairs including removal and replacement of all steel base plates, cap plates, connection plates, and connections. Reinforcement, reconstruction, and modifications of the abandoned aerator tower would likely not be practical compared to new aerator tower construction uniquely designed for the specific project and site requirements. Based on pricing data for similar work,KI W estimates the probable cost of the above recommended action to seal the top of the steel tube X-bracing at the Ravines WTP aerator tower will be approximately$9,500.00. to KIW Structural Engineers K I W Project: 21244 January 14, 2022 Page 26 of 27 Postmaster's Village Water Treatment Plant#1120 The aerator tower at the Postmaster's Village Water Treatment Plant(WTP)is located at 6511 County Road 214 in Keystone Heights, FL.
