panel will be replaced. The wet well tops will be replaced and modified with sealed hatches. Our assumption at this time is that the rehabilitation can be performed. If during the design process we uncover factors that will require a complete reconstruction of the lift station, a proposal will be provided for services associated with the change in project scope. The wet well walls were briefly examined during the site visit and indicated light to moderate deterioration of the wet well walls, however the walls are dirty and blast cleaning during the rehabilitation process will provide additional information as to the wet well wall condition and the need for grouting prior to applying any spray on coatings. The control panel will require replacement as well as all controls and electrical components. SCADA and remote alarm or information controls are not a part of this project. From preliminary information supplied in the Manning report, it appears that there will be sufficient depth to allow for acceptable pump cycle time and operation and at the same time maintain adequate water levels over the submersible pump volutes. Run times and pump level settings will be determined with the selection of the pumps during the design phase. Access to L.S.#8 is provided by a newly constructed concrete driveway from King Williams Drive with a concrete turn around near to the lift station. Additional site work and paving will be required for access to the station and to improve site drainage and maintenance requirements. L.S.#32 is accessed from a driveway from Underwood Road which appears adequate and additional significant site work and paving is not anticipated. The City has budgeted $225,000 and $200,000 for the construction cost and engineering for the rehabilitation of lift stations No.8 and 32 respectively. These budgets appear adequate based on our previous experience with similar projects and will be evaluated and updated as the project progresses. This proposal addresses the engineering services that CMI will provide the City of La Porte during the Design and Construction Phases. CMI will utilize an electrical subconsultant for the electrical components and control system designs. Since it is anticipated that all work will be confined to the existing station, no surveyor geotechnical work is included for this project. SCOPE OF SERVICES I. DESIGN ENGINEERING PHASE A. Perform field reconnaissance and partial survey of the site and immediate vicinity to obtain information on surface features and any other information that would impact construction. A detailed topographic survey will not be performed. A geotechnical evaluation will not be performed. B. Research and gather existing relevant data on the project such as existing utility information. Page 2 of7
