Compliance with regulatory requirements, coupled with early coordination with regulators, is paramount to smooth project approval. Maintaining facilities in service during construction. Special Considerations for Non -Potable Facilities • Stored water quality can be more difficult to maintain and therefore requires special attention regarding the tank volume, residence time in the tank and circulation. • A higher degree of settlement in storage facilities can lead to the need for more frequent and special equipment for clean -out operations. • Configuring facilities to properly handle planned discharges such as wash down, as well as unplanned discharges like tank overflows, must respect regulatory constraints and may require special features to control flows (e.g., discharge to a sewer). • Compliance with regulatory requirements, coupled with early coordination with regulators, is paramount to smooth project approval. PROJECT MANAGEMENT APPROACH We've derived our project management approach from many years of experience and proven success, and it includes very specific strategies: coordination, communication, and documentation. COORDINATION: All task orders require coordination. This may include coordination with other City departments, local agencies, and stakeholders. The Ardurra team has years of experience with major on -call contracts with Southern California agencies. These on -call contracts require similar coordination efforts in which Ardurra has established and maintained outside -agency contacts, coordinated the designs with their staff, and received the approvals to move the project forward. This knowledge and understanding of working with other agencies provides great benefit to you for each project. COMMUNICATION: Ardurra has a formal, proactive communication plan to share critical project information as soon as possible and to make sure there are no surprises. We continuously report progress, identify problems, assign priorities, receive feedback, and document progress. From project start-up through project closeout, we will prioritize our communication to make sure we document and address all required actions timely. We assure you that your team and our team will always know the status of your projects. This level of coordination, coupled with the project progress meetings, helps avoid project issues and delays, and ensures that the project is on schedule and within budget. Ardurra has used this management approach with great success on all types and sizes of projects. City of Santa Ana I March 14, 2023 On -Call Engineering Services, RFP No. 23-030 /\/ARDURRA
