TAIT & Associates, Inc. On -Call Engineering Services Newport Heights Alley and Sewer Replacement Project Newport Beach, CA TAIT was selected by the City of Newport Beach to provide civil engineering services on Newport Height Alley and Sewer Replacement Projects. The project limits spanned across an entire neighborhood in the City's coastal community of Newport Heights and include a total of 3+ miles of alley reconstructions as well as the review and repair of existing alley sewer and lateral connections. In order to facilitate the City's budget and timelines, the design project was split in to three phases which required separate design PS&E for each project. Phase 1 included all sewer main replacements while Phases 2 and 3 included the alley removal and replacements in the neighborhoods. The proposed design includes the preparation of design plan and profile for each alley, prepare of design cross sections at 25' intervals for review of proposed cross falls, preparation of sewer main replacement and lateral replacement plans, field review of all alley locations to field locate existing utilities, conflicts, and join locations, identification of sewer laterals that have recently been replaced for protection, and the detailing of all alley approaches for ADA compliance.

The analysis included field investigations, geotechnical testing and reporting, pavement design, and the preliminary design and cost estimating for multiple design scenarios at each project location. The cost estimate included estimation of the design consultant fees as well as the construction costs for the ultimate design scenarios. Extensive coordination was required on this contract with City, Utility, LACFCD Staff, and private residences in order to understand the existing conditions and to project the required design and permitting efforts for the design and construction phase. Upon completion of the report, the City will utilize TAIT's recommendations for future CIP budget and project planning efforts in order to justify the cost and importance of each location.
