After the City of Santa Ana completes their review of the 30% design package, Tetra Tech will initiate the final design phase. Tetra Tech will produce a 60% design package, final Independent Design Review (IDR) package, and then a Final design package. The City will review each of these design packages, and the Tetra Tech team will work closely with the City to address comments, make adjustments, and ultimately produce the final, approved, design package. Design review meetings will be held after the 30%, 60% and final IDR design level completion. The 30% On -Call Engineering Services design review meeting will focus on confirming the project's design meeting the goals and intent that the City has for the project. The 60% review meeting focuses on the constructability of the submitted plans, specifications, estimate (PS&Es), geotechnical report and other supporting reports and calculations. The Final IDR design review meeting will ensure that all City comments and concerns are addressed prior to the design team finalizing the Final PS&E bid package. Meetings will be attended at a location selected by the City. Tetra Tech will prepare meeting minutes for each.

Inadequate resources can result in project delays and/or poor execution of required tasks. Tetra Tech is ready to provide support to the City with our experience and knowledge to quickly resolve technical issues and challenges. The Tetra Tech team can provide the specialized expertise and the depth of resources necessary to meet or exceed the City's variable project requirements. The depth and breadth of our team's technical expertise is described in the following sections. DETAILED DESIGN Field Investigations: Conducting thorough field reviews on projects is another critical component of cost-effective project management. Tetra Tech believes very strongly in walking our projects in the field throughout the base mapping and design stages of a project to insure all design issues are considered. This task can be particularly important on the City's future projects due to the variety of conditions that exist within potential project footprints. Therefore, we will conduct thorough field TETRA TECH
