0 0 SECTION II: WORK PLAN The following is a project approach, and work plan for a typical roadway rehab i I itation/rec onstruction project. This sample information is provided only as an example of tasks required and a comparative level of effort for the services necessary to complete the project. The deliverables will be provided in imperial or metric format. A. PROJECT APPROACH Our approach to a typical roadway engineering services design project, is to meet early with City of Santa Ana staff and other impacted agencies, if applicable, in order to establish scope, schedule and process. Once we have prepared the final scoping documents and are issued a Notice to Proceed, we will begin the preliminary phase of the project which typically consists of research and data collection; utility identification, coordination and investigation; field site survey; identification of facilities to be modified or replaced; and preparation of preliminary plans for the proposed improvements. ASL will utilize existing information that is available from previous studies, reports, investigations and analyses as a basis to begin the design work. This information will be augmented and updated, where required. Because they are typically on a project schedule's critical path and usually require substantial lead -time, the following tasks will begin immediately upon receipt of Notice to Proceed: y • Research and Data Collection • Utility Identification and Service Point Coordination • Field Site Survey and Verification of Existing Facilities • Identification of Right -of -Way ASL will meet with the City staff responsible for review of a specific element of the preliminary plans as we are working on them. Draft copies of this work will be submitted for significant work items before the milestone submittal date with follow -up meetings to solicit input. This early coordination gives us a clear understanding of what the reviewers expect while giving the reviewers a preview of what will be submitted before the actual submittal is made. Design of street and roadway improvements in highly urban settings is a service which ASL has been providing to public works clients in Southern California for the past 50 years. We understand the complexity of retrofitting urban streets, alleys and access ways while maintaining basic services, traffic flow and minimizing impacts to the roadway user. Specific elements related to street and roadway widenings, overlay and/or reconstruction projects include: • Horizontal and Vertical Alignment • Pavement Section Design • Utility Adjustments • Utility Relocation • Drainage (Drainage issues are exacerbated in flat areas where cross fall and longitudinal grades are minimum) • Construction Staging • Construction Traffic Control • Permits and Approvals (Typically urban settings involve multi - agency approvals which require planning, communication and follow through to successfully process) Key Project Issues Based on previous experience with similar projects, the following are typical key issues that will impact the overall design and successful construction of street rehabilitation /reconstruction related improvement projects. • Survey/Base Mapping — Coordination of the new work with existing improvements and any proposed adjacent improvements becomes critical in providing a project that is constructable. Such items as valve boxes, manholes, vaults and other in- street improvements can cause significant problems during construction, if not addressed during the design phase. Our site survey and development of base mapping, in conjunction with field job walks before the preliminary and final plan submittal phases, will minimize potential for oversight in this area.
