iNli' 1 Bridge Structural Design Services Scope of Work The following is a summary of the key elements of work for the project. Task 1 —Administration 1.1 Management & Adminstration- This task includes tasks such as subconsultant agreements, monthly progress reports, and tracking hour and cost expenditures. A project specific Project Work Plan will be developed which includes our quality control procedures, and will be distributed to all team members. 1.2 Project Team Meetings— DMJM Harris will organize and participate in a project kickoff meeting with the City and all project stakeholders to discuss the scope of work and review procedures to be followed for project communication, processing and approval. DMJM Harris will organize and conduct regular PDT meetings throughout the duration of this project phase on a monthly basis (8 meetings assumed), and will also be available for public outreach, City Commission and City Council meetings (2 total meetings assumed). The DMJM Harris Project Manager and Engineers will also participate in informal, unscheduled meetings as necessary as critical issues arise. 1.3 Agency Coordination — DMJM Harris will be responsible to coordinate with outside Agencies as necessary to address Project and permitting issues. This will include, but is not limited to, Caltrans, the County of Orange, the Corps of Engineers, OCTA, RWQCB and CDFG. 1.4 Record Research & Field Reviews — Existing as -built information and all available studies will be obtained and reviewed. A minimum of three field reviews, including a digital photographic inventory, will be conducted at various stages of the project to ensure all field conditions have been accounted for in the Project plans. The initial field review will be basis for the preparation ofthe "Field Review Report" in conformance with Caltrans requirements. 1.5 Utility Coordination — Initial requests for utility information will be sent to each utility company and a master base map of utilities will be developed from the information received. The existing utilities, as well as proposed relocations, will be shown on the project plan & profile sheets. Meetings will be conducted with the impacted utility companies as needed to convey the project impacts and coordinate their relocations. (6 meetings total provided). A conceptual relocation plan will be developed and distributed to each company for their input, modification, schedule, and cost (if applicable). Utility notices will also be sent out at the 60% and 100% levels to ensure concurrence of their facility locations as depicted on the plans and their relocations, if applicable. DMJM HARRIS AECOM Task 2 —Engineering Studies 2.1 Survey — DMJM Harris team member, Coast Surveying, will perform initial field control, topographic survey and aerial mapping. Provide overall site mapping for base mapping purposes and design purposes at 1 inch = 40 feet accuracy, with 1 -foot contour intervals. • Perform survey research at the City of Santa Ana and the County of Orange for horizontal and vertical control, centerline ties, right of way maps, record maps, and any other pertinent information. • Place five aerial photogrammetric control targets on the ground and determine appropriate horizontal and vertical control positions upon them. • Prepare aerial photogrammetric mapping 200 feet wide, 100 feet each side of centerline First Street from 600' E/O to 600' W/O bridge, and within the Santa Ana River 400' each side of First Street, at a scale of 1 "=40' with one -foot contour accuracy in MicroStation digital format in U.S. Survey Feet per the City of Santa Ana Standards. • Perform design surveys along First Street from 600' E/O bridge to 600' W/O bridge. Deliver a MicroStation digital file of the survey results and a .txt file of all the survey points with point number, X, Y, Z and descriptor. • Perform cross-sections at 100' intervals of the Santa Ana River 400 on each side of First Street. Deliver a MicroStation digital file of the survey results and a .txt file of all the survey points with point number, X, Y, Z and descriptor. • Perform field surveys to tie-in street centerline monumentation on First Street on each side of the Santa Ana River, and determine appropriate horizontal control positions upon them and then compute the existing centerline through the project area. • Compute appropriate right of way lines in project area using the established centerline positions and record data. Provide right of way delineation mapping in MicroStation digital format in U.S. Survey Feet. • All surveys will be tied into the appropriate County of Orange horizontal and vertical control datums utilizing both GPS Receivers and digital levels. 2.2 Geotechnical — Team member, Earth Mechanics will provide the geotechnical support which will evaluate the existing subsurface conditions and general onsite soil characteristics, and to provide recommendations for the proposed improvements. The scope of work is anticipated to include the following tasks: Soil borings will be required for the retaining walls and abutment foundation, and pavement design. Borings are also recommended inside the river because the existing borings are not deep enough for deep foundation design. 04601 324.5557 12
