Project Approach Task 6: Complete all Necessary Field Work Description:Field work will consist of completing a full site topographic survey of the wastewater treatment facility area. Bolton &Menk employs our own surveying staff and they will conduct the survey of the treatment facility site.All marked utilities will be noted on the survey. It is critical that soil borings are obtained and a geotechnical report be completed before starting the full design process. The soil boring information is very important for the structural design portion of the project. Bolton&Menk will obtain quotations from at least two geotechnical firms and Bolton&Menk will provide the City with a recommendation on who should be hired to complete the geotechnical work for the project. The geotechnical work will consist of the design work including soil borings and a geotechnical report and materials testing such as density testing, soils analysis and concrete sampling and testing. The City of Elk River will pay for all geotechnical and special materials testing directly. Bolton &Menk will direct the geotechnical subconsultant on the type and quantity of testing that is required for both the design and construction phases of the project. Task 7: Organize, Schedule, and Attend Equipment Reviews at Other Treatment Facilities Description: Touring other treatment facilities is an important step in the design process and allows the operations staff to see similar processes,understand how they work, and most of all, allow for discussion with other operators to find out the pros and cons of their system. Bolton& Menk has arranged similar facility tours for many clients and will arrange tours and attend these tours with the City. Tours of other treatment facilities allow the operations staff to see what they like,but just as importantly,it allows them to see things that they don't like or don't want at their facility. These tours also introduce them to other treatment facility staffs and these staff persons then become another resource for the operators. In addition, it is often helpful to have equipment vendors visit the treatment facility and provide information on specific pieces of equipment, especially if there are no installations nearby. These types of meetings allow for comparisons of multiple pieces of equipment from various equipment vendors. Bolton&Menk will setup meetings with equipment vendors and also facility tours. Task 8: Design New Improvements Based on Selected Option Description: Once the selected options are determined,the final design process will begin. Some of the preliminary design will have already been finished through completion of tasks 1 through 7. As noted above in Task 3, Bolton&Menk encourages the input of the operations staff and Bolton &Menk will meet with the City multiple times throughout the design process to solicit input and provide updates on the design process.At a minimum, Bolton &Menk will provide review plans and specifications at the 50 percent, 90 percent,and final plans for City review and comment. Along with the review sets, Bolton&Menk will provide updated construction cost estimates. The design process not only includes the design work necessary for the proposed improvements but also requires working with the MPCA on the various permitting requirements. This includes the completion of a non-degradation review, Environmental Assessment Worksheet and the modified NPDES permit. Wastewater Treatment Facility Improvements I City of Elk River, Minnesota 3
