and stakeholders, and will work collaboratively with these parties to ensure smooth execution of the complete project plan. We understand that these projects may require clear communication with local stakeholders and regional transportation agencies. iasK s - uata uainering ana meview IBI Group will prepare a detailed data needs memo following the initial meeting. IBI planners and engineers have years of experience in working with municipal transportation departments. The project manager understands that City staff has multiple demands on their time, therefore IBI Group correspondence will be clear, concise, and well organized. Data requirements will be clearly detailed in order to save time. IBI staff will research City records for prior approvals, including resolutions and conditions of approval, as necessary. In addition, IBI Group has experience contracting traffic counts and performing field reviews. IBI Group will review data gathered from other sources for accuracy and relevance. Task 4 — Traffic Analysis Specific Tasks In the category of traffic engineering, IBI Group will approach projects from a comprehensive perspective. IBI Group understands that traditional traffic engineering and traffic modeling approaches do not always support multi -modal planning. Further the transition to VMT-based analysis will require adjustments to the approach in how traffic studies are completed and in the identification of project mitigation measures. IBI Group understands the importance of providing rigorous traffic engineering. As shown in our firm qualifications, IBI has extensive experience in developing traffic generation and parking demand estimates for innovative projects that include Transportation Demand Management (TDM) components. We will apply our expertise in these areas on any projects to satisfactorily complete these assignments for the City. Task 5: Prepare Preliminary Design Plans IBI Group will prepare plan, profile, typical sections and construction details including intersection contour plans for street widening or areas of overlay and rehabilitation. Alternatives will be prepared to evaluate various impacts, constraints, costs, and geometric solutions to achieve the proposed street cross section and right-of-way. The traffic study will define the groundwork for identification of the proposed improvements including number of lanes, location and length of turning pockets, need for signals, etc. Development of project alternatives will involve coordination with the traffic engineers to determine the geometric needs. Design will commence using an iterative process with the traffic information to determine conceptual geometrics and determine if more than one alternative is warranted. The team will assess the data along with project goals and objectives to develop alternatives for further evaluation. Task 6: Preliminary Cost Estimate For each alternative, IBI will prepare a conceptual project cost estimate that details estimated quantities and unit costs for major work items, including right-of-way acquisition, drainage improvements and utility impacts. Project cost estimates will show quantities and unit prices with back-up calculations for all quantities. Preliminary cost estimates will be provided at each draft submittal and a final estimate will be provided with the final Project Design Report. Task 7: Prepare Project Final Report After the completion of the tasks above, IBI Group will prepare a Project Final Report in accordance with the City of Santa Ana's requirements.
