(ENGINEER) WASTEWATER TREATMENT PLANT - UV DISINFECTION -- SYSTEM EXPANSION ENGINEER is currently engaged in the execution of Task Order 10055 in support of the Wastewater Treatment Plant UV Disinfection System Expansion project. ENGINEER is following a traditional step -wise, phased approach to performing the work associated with design of the UV system. The project design approach consists of: • Project Definition and Alternatives Evaluation — identify target capacity and redundancy goals, develop alternatives, assist City with selecting preferred alternative to advance to design • Preliminary Engineering and Design (30 Percent Design) • Equipment Procurement — assist City with procurement of UV disinfection equipment upon which to base facility design details • Design Development Documents (75 Percent Design) • Bid -Ready Documents (100 Percent Design) • Bid Period Services — assist City with bid process for selecting a general construction contractor The project is being delivered in two phases to align task order budget with City fiscal year budgets. Per the list above, Phase 1 carries the project through the Equipment Procurement task and Phase 2 will advance the project through Bid Period Services. The initial Task Order 10055 is considered Phase 1 and this Change Order No. 1 constitutes Phase 2. The tasks associated with this Change Order No. 1 are more fully described in the Scope of Work section below: Task 1 — Project Management (Additional) Additional project management will be provided by ENGINEER to manage, coordinate and lead ENGINEER Team's activities and perform administration of the project design services and project quality reviews. ENGINEER will provide the resources necessary for project management throughout this phase of the project as described in the initial Task Order 10055. Change Order No 1 to Task Order 10055 Page 2 of 9 Wastewater Treatment Plant UV Disinfection System Expansion Deliverables • Periodic written project design schedule updates to keep the City's Project Manager informed as to the changes to the initial schedule outlined in this Scope. • Monthly project invoice statements with a brief description of the work performed. Meetings (Unique to those identified below) • Bi -weekly telephone meeting conducted between City Project Manager and ENGINEER Project Manager to discuss project status, review actions/issues pending, and other project coordination. Task 6 — Design Development Documents (75 Percent Design) — Phase 2 Task The purpose of this task is to utilize the decisions of the project that were made in the Preliminary Design Phase (30 Percent Design) and the results from the UV equipment pre -purchase effort to complete and finalize the preliminary calculations of the previous phase, and develop the project design to achieve a true "design freeze" at the conclusion of this phase. The completion of this design phase will constitute the final design and allow the City perform a final review of the contract documents.

A workshop will be held with the City's personnel to receive and discuss comments and to reach closure on design issues. Additionally, City WWTP operations staff will be relied upon to discuss construction sequencing and plant operation during construction. Existing plant operating facilities that will be impacted during construction will be identified. A preliminary sequence of construction will be developed to accommodate operation with minimal plant disruption. The tie-ins to existing facilities will be discussed, need for process or plant shut -downs identified, the duration for tie-ins discussed, and the maximum duration that facilities can be shut down documented. A memorandum summarizing the discussions will be produced and provided for City concurrence. Following the workshop, meeting minutes and responses to comments will be prepared and submitted.
