Scope of Work Preparation of Plans,Specifications and Estimates Sunol Boulevard/1-680 Improvements Project August 21,2023 4. Utility Relocation/Occupation Plans (scale 1"=50') AECOM will identify and propose existing and final locations of known utilities that are affected by the Project, such as gas, electric, cable TV, telephone, sanitary sewer, and water. The relocation design of utility facilities will be the responsibility of the utility owners. 5. Drainage Layout Sheets AECOM will prepare the preliminary Drainage Plans/Profiles and Detail Sheets. The design efforts will be coordinated with other design disciplines of the Project Team. Drainage plans will be prepared at a scale of 1"=50' showing existing and proposed drainage systems. 6. Pavement Delineation will be prepared at a scale of 1"=50'. 7. Sign Plan (scale 1"=50') A field survey will be conducted and used to develop inventory of existing roadway signs and will be confirmed with as-builts found. Sign plans will be developed depicting both existing and proposed signs within the project limits. Task 3.2 Utility Identification and Verification AECOM will verify that known utility information shown on plans and other documents prepared by AECOM are current and have been coordinated with the utility companies, the City, Caltrans' Right-of-Way Utility Coordinator and Caltrans Right-of-Way Project Coordinator. Existing utilities will be located using the latest as-builts, visual inspection of surface features, and other available data. Where required, potholing will be conducted to positively identify utilities, including the high risk utilities. AECOM will locate and map existing utilities that potentially conflict with the proposed improvements, and prepare utility conflict maps identifying the accommodation, protection, relocation or removal of the existing facilities that conflict with the construction of the Project or that violate Caltrans encroachment policy including utility relocation design plans. These relocation plans will be submitted to affected utility owners for coordination, input, and to obtain their design for the facilities that they are responsible for relocation. AECOM will provide copies of the utility conflict maps, relocation plans, proposed notices to owners, report of investigations and agreements for Caltrans concurrence prior to issuing the notices to owners and executing utility agreements. Utilities that are required to be positively located will be potholed, reference surveyed and plotted. Approximately 15 potholes and 30 electronic probing are planned. AECOM will perform the following activities: • Pothole and verify utility locations and provide horizontal and vertical surveying. • Coordinate utility impacts and relocations caused by the proposed construction. • Prepare utility agreements, including utility relocation claim letters, Notice to Owners,utility relocation design plans, and utility conflict maps. • Develop utility plans (U- drawings) that indicate utilities to be relocated and utility envelope plans.
