18. RW -VA — a mechanically stabilized earth wall along the south side of SB Veterans Blvd. approach to flyover. Total length is approximately 689'-6"; design height varies from 4' to approximately 24'. The Type Selection Report will include the following: • General Description of the Project • Design and Constructability Issues • Structure Type Selection and Support Location Considerations • Foundation Issues • Speed of Construction • Staged Construction of the Structures • Preliminary Aesthetics • General Plans • Construction Costs • Recommendations Results from the Advanced Planning Studies previously prepared by AECOM, Preliminary Foundation Reports and structural and visual design criteria will be used in developing General Plan details. This includes performing preliminary analysis to aid development of structural elements such as depth and type of the superstructure, size and shape of column members, footing sizes, and abutment types. The analysis will be consistent with the preliminary nature of design. Preliminary Construction Structure Quantity and Cost Estimates in a Caltrans General Plan format will be developed for the project at this stage. The list of items of work will be prepared based upon Caltrans' Standard Items of Work and adding items as may be necessary. The cost estimate will identify construction work items, quantities, unit costs, and summarize the estimated total structures cost, including allowances for supplemental work, owner furnished materials, expenses, mobilization and contingencies. The type selection report will include discussions noted above and will consist of a type selection memo, bridge site data submittal (BSDS), a vicinity map, General Plans, construction cost estimates, for each of the structures. The results of the single type selection report for the seven bridge structures and the eighteen non-standard retaining walls will be presented in a meeting at Caltrans Division of Engineering Services (DES) in Sacramento. AECOM will be prepared to discuss and provide information on foundation requirements, false work requirements, seismic and aesthetic considerations, traffic handling, construction cost and other pertinent information that is needed to determine the proper structure type. This is the "Structure Type Selection" process and no further design work will be performed until written approval of the structure type is received from DES. Within two weeks after receiving written approval of the proposed General Plan and structure type, AECOM will furnish DES with appropriate copies of the approved General Plans. These will be distributed by Caltrans for comments in accordance with Bridge Memo to Designers 1-5 or current policy, and comments received will be Page 35 of 73 REV: 07-18-17 PR AM/AGR.2017.166/AECOM 101/84 PS&E
