the adjacent park pond will also need to be evaluated to verify water levels are maintained during construction and not impacted by the project. This may require back feeding water to the pond to maintain proper levels. Dewatering can be one of the larger challenges on this project. With proper planning, this can be managed to become a marginal risk item on the project. Maintaining Process Flows. We understand that this project will require a bypass pumping system to maintain CSO flows to the plant during the construction of the new diversion and outfall structures. A temporary system may also be necessary to tie in the new 48" interceptor piping. We approach bypass pumping by evaluating the flow requirements to the plant, risk associated with the pumping setup, and length of time the system must be in operation. We want to minimize the amount of time bypass pumping is required, simply because of the risk and cost these systems can have on a project. We also setup our systems to have redundancy and alarms to ensure potential mechanical issues can be remedied timely, with little to no impact to the bypass system. Kokosing will contract with a bypass pumping specialist that has the ability to engineer and provide a redundant system to meet the CSO needs for this project. A system with multiple pumps and flow level controls will likely be required to maintain CSO flows to the plant, but discharge to the river should flows exceed 77 MGD. Due to the risk and coordination efforts required for a system like this, we will ask that American Structurepoint and plant personnel be heavily involved in the planning process for this system to verify it meets your process requirements and permitting limits. D. CONSTRUCTION PLAN AND APPROACH Kokosing's approach to scheduling and managing every project starts with a firm understanding of the project scope, risk components, process constraints, and milestones set by the client. We then break the schedule into phases of work, from preconstruction through construction, followed by project closeout. This project will involve two separate scope upgrades to the plant with the CSO 045 EQ Basin improvement and Final Clarifier 1, 2, and 3 improvements. Although our master CPM schedule will include all activities for both scope improvements, we will track the construction phase of work separately so each can be managed independent of each other. Preconstruction Phase The preconstruction phase of this project will start with an understanding of plant operations, current design, and the establishment of project milestones for construction. Immediately after this section, we have provided a preliminary conceptual project schedule showing many of the pre -construction and procurement items that will be required for the project. This schedule will be refined as additional information is provided, but it will show how we will work collaboratively with American Structurepoint and the City of South Bend through the preconstruction process to get the project to construction. A design and permitting schedule, aligned with GMP budgeting will need to be established so contracting and material/subcontractor procurement activities can begin. We know that some materials and equipment will have long fabrication lead times, therefore, those items will be targeted for early procurement. These items would include the electrical scope, generator, VFD's, controls, piping, rebar, pumps, clarifier equipment, and dewatering. Getting these subcontractors and vendors on board early in the procurement process will help get submittals and releases for fabrication going to maintain and/or exceed project milestone expectations. In the event a particular equipment item has a lead time that will impact the intended schedule before IDEM permitting approval or the establishment of the GMP budget, we do have the option to issue a limited notice to proceed for that particular item and discuss the procurement with IDEM. We have had similar situations on other projects where pumps have been released for submittal/engineering prior to the establishment of the GMP If this becomes necessary, we will work with you to get the necessary approvals and allow these portions of work to proceed.
