Exhibit A (Scope of Work) • Flexible pavement design for Terminal Ave/W Marine View Dr intersection (WSDOT Jurisdiction) • Rigid and Flexible pavement design for W Marine View Dr • Flexible pavement design for Pacific Avenue • Flexible pavement design for Rucker Avenue/41st St intersection The subgrade strength parameters (resilient modulus) will be provided in the Geotechnical Engineering Report and through Falling Weight Deflectometer (FWD) testing. Pavement core samples will be collected at project sites for FWD analysis. Traffic volumes, including percentage and classification of trucks, will be used from the information generated from the forecasted traffic volumes. The pavement sections will be shown on the typical roadway sections on the civil design plans. Recommendations for pavement design will be presented in a pavement design memorandum. The consultant will finalize a memorandum based on review comments. Consultant will perform field evaluation of existing pavement conditions along West Marine View Drive between Pacific Ave and SR 529/Terminal Ave to determine areas of preservation and recommend areas for rehabilitation. Consultant shall meet and review existing pavement conditions with City to determine priorities for preservation and rehabilitation, and review need for additional analysis to be performed. WSDOT has jurisdiction over the intersection of Terminal Ave/W Marine View Dr. Consultant will design the intersection to the requirements of WSDOT’s Pavement Policy using a design life of 50 years. The consultant assumes that 2 meetings may be required for resolution of comments with WSDOT. Should reviewing agencies request additional designs, Consultant shall develop additional scope and level of effort based on agency requirements for approval. Retaining Wall Design Recommendations Consultant will evaluate the data derived from field investigations and laboratory testing to complete geotechnical engineering analyses to provide design recommendations for the proposed retaining walls. Consultant assumes that modest retaining walls along the corridor will consist of SEW walls that are designed for internal stability by the contractor. For these walls, Consultant will evaluate global stability and provide recommended soil input parameters to be include in the project specifications. For taller walls a structurally intensive wall system may be necessary and for these walls, Consultant will evaluate global stability of the walls and provide earth pressures and design recommendations. Signal Pole and Luminaire Design and Recommendation Consultant will evaluate the data derived from field investigations and laboratory testing to complete geotechnical engineering analyses to provide standard signal pole foundation recommendations for the signalization improvements.
