D. UNDERSTANDING SCOPE <br />OF SERVICES <br />Though no project can follow a "cook book" approach, there are many things we've learned over <br />the years that form the basis of our initial thinking for reservoir rehabilitation projects. The critical <br />and/or unique elements of this project are significant but not unusual. <br />As noted above, we view reservoir projects as civil engineering designs with a hydraulic emphasis. <br />If you don't get the hydraulics right, everything else falls apart. We take understanding existing <br />hydraulics very seriously, and recognize it as and one of the most important aspects of a reservoir <br />rehabilitation design. <br />Our experienced structural team has successfully rehabilitated concrete tanks up to 21.5 MG. We <br />have found what makes a reservoir project unique are the hydraulic considerations and ensuring <br />water reliability and water quality. Items we address in our assessment of the pros and cons for <br />each alternative include: <br />1. Hydraulic considerations. How does the reservoir function with the entire system? <br />2. How is flow distribution within the reservoir handled? <br />3. How is water quality assured by proper distribution and mixing over a continuous period? <br />4. How can we assure reservoir turnover to manage the "age of water"? <br />5. Access for operations and maintenance: How do we assure safe access, where do we locate <br />new hatches, and how do we provide adequate ventilation and lighting? For example, BRADY <br />strongly recommends that internal stainless steel stairs be installed to eliminate the need to <br />scale a 20 to 30- foot ladder, no matter how many safety measures are provided. We strive to <br />eliminate any way a person can be injured by entering a reservoir. <br />6. Overflow and drainage. Where does overflow discharge to? How is drainage of the reservoir <br />satisfied? <br />Designing for the City's O&M personnel is a critical success factor and BRADY will work closely <br />with the City's O&M staff. Though it may be a functional solution to a problem, a project is <br />often considered a failure by the designers in hindsight if the needs of O&M are not thoroughly <br />satisfied. <br />In addition to the technical approach, a well thought out management approach is the other side <br />of the balance beam. We know from our long history in the water business that schedule and <br />budget compliance are critical success factors. We know the City has the public to answer to, <br />and there is nothing worse than going over budget or long on schedule which means going back <br />to the City Council. Making sure we don't go down this path begins with a clear understanding <br />of the project's scope and the City's specific requirements, the assembly and commitment of an <br />experienced team along with all necessary resources, establishment, monitoring, and maintenance <br />of the project's deliverables within set parameters, which includes schedule and budget, and <br />RICHARD BRADY &ASSOCIATES, INC. <br />25B-85 <br />
