Report
Summary
The rehabilitation program was established to provide an overall approach to assess and rehabilitate steel tanks and to prevent them from deteriorating over time based on their coating, structural and site conditions. The program includes maintaining the coating and structural integrity of these steel tanks, enhancing water quality (recirculation systems, mixing, disinfection system upgrades, etc.) associated with the steel tank sites, and providing site-related improvements such as erosion repair, upgraded fencing, and other improvements. This program has grouped all the tanks into near-term, mid-term and long-term categories and established a master Preventative Maintenance schedule for tank inspections, assessments, design, and rehabilitation activities.
Wilson Engineers, LLC's Design Services include, but are not limited to: reviewing and updating the steel tank triage report; performing dry inspections and assessments; modifying the steel tank ranking based upon inspections and assessments; providing rehabilitation design; and assisting with overall program data management for the City's Work Order Asset Management system.
Wilson Engineers, LLC's possible CA&I services would include, but are not limited to: providing project administration and engineering services during construction activities; inspecting the site through various stages of construction; reviewing contractor work submittals; performing field inspections for completed repairs; and providing resident services during construction.
