Technical specifications for recoating were developed and the project was initially bid out by the City.However,the City would now like to revise/redevelop the technical specifications and submit new technical specifications for coating the EST through an addendum, before reopening the project for bidding.The City has requested that this task be expedited,and the new technical specifications be provided to City staff by December 20. In this regard,the City has requested LNV, Inc. (LNV)to review the existing specifications and provide a recommendation for best path forward. After an initial review of the specifications,LNV determined that it would be best to inspect the interior and exterior of the EST to determine the cause for the current condition of the coating. Based on the results of the inspection, new technical specifications will be developed based on the defects noted and the recommended repairs. Under this task authorization,a complete inspection of the exterior and interior of the current condition of the EST will be performed. The Engineer will then provide tank rehabilitation recommendations and develop technical specifications for the City to implement suggested recommendations. In addition to these services, construction phase inspection services are critical for the success of the recommended improvements. The scope of the construction phase services is difficult to determine at this stage. The scope will be better defined post the initial inspection and a separate task authorization will be submitted to the City for these services.

Notes on scope of work: i. The City will provide access to the EST for inspection including access to tank pedestal door and roof hatch. ii. A remote operated vehicle(ROV)will be used for internal inspection of the tank.The EST will not need to be taken out of service for inspection. However,it is recommended that tank level during the inspection be at least 50%and the pumps/inlet/outlet valves be shut off for the short duration of the internal inspection(-30 minutes).
