■ AECOM Robert Price, PE Retaining Walls Education and Registrations BS /1992 /Civil Engineering Coursework, Reinforced and Prestressed Concrete Design, Arizona State University PE /1995 /Arizona No: 29684 (Civil) PE /1997 /California No: 56855 (Civil) in M = Mr. Price has extensive experience in the bridge field including over 14 years in the design of steel girder, post - tensioned and reinforced concrete box girder, precast - prestressed concrete I girder, and segmental box girder bridges for highways and railroads from conceptual to final design. He is also experienced in the design of special steel erection equipment and precast concrete segmental viaducts; travel- ing maintenance scaffolding for major bridges; and seismic retrofit and repair of steel plate girder, truss, and concrete bridges. He has been a project engineer on highway bridge replacement and rehabilitation (HBRR) projects in California and is familiar with Caltrans local programs procedures. He has supervised preparation of construction documents and prepared engineering estimates and specifications for roadway and bridge projects in Arizona, Nevada, California, and international projects. He also has designed major arterial street projects for large metropolitan cities, and is experienced in many design -build projects. Hageman Road Grade Separation Project, Kern County, California Senior Bridge Engineer for the independent design check for two underpass structures. Cameron Park Drive /Palmer Drive /Country Club Drive Interim Improvements, Cameron Park, California: Project Manager for interim safety improvements for two intersections in close proximity. The safety improvements included adding lanes, right turn pockets, re- stripping and signals. Plans included drainage improvements and retaining walls. The Old Road Bridge at Castaic Creek (Replace) & Tieback Wall at Honor Ranch Road Overcrossing, County of Los Angeles, California: Engineer of record, responsible for the design review and PS &E of the bridge. The widening of The Old Road at Honor Ranch Road Overcrossing required a tieback wall of 13.5 feet in height. Plans included separate plans for the Tieback Wall. Cameron Park Drive /Palmer Drive /Country Club Drive Interim Improvements, Cameron Park, California: Project Manager for interim safety improvements for two intersections in close proximity. The safety improvements included adding lanes, right turn pockets, re- stripping and signals. Plans included drainage improvements and retaining walls. The environmental documentation included a mitigated negative declaration prepared by PMC, our sub. The Old Road Bridge at Castaic Creek (Replace) & Tieback Wall at Honor Ranch Road Overcrossing, County of Los Angeles, California: Engineer of record, responsible for the design review and PS &E of the 3 span, 250 foot long, 4' -3" deep, 76' -9" wide post- tensioned cast -in -place concrete box girder bridge. The bridge plans are staged with the construction of the western section while the existing bridge remains in service. The pier walls line up with the neighboring twin 1 -5 bridges to maximize hydraulic capacity of the creek. The footings are below scour depth and use steel H- piles. Approaches include a type 5 (L shaped) retaining walls at the 1 -5 right -of -way. The widening of The Old Road at Honor Ranch Road Overcrossing required a tieback wall of 13.5 feet in height. Plans included separate plans for the Tieback Wall. 1 -80 Nut Tree Road OC (Widen), Vacaville, California Engineer of record, responsible for the design of a bridge widening, and a specially designed retaining wall (mechanically stabilized earth) for this project. The submittal for the Structure Type Selection and Seismic Analysis for the 99.518 meter long four span cast -in- place, prestressed concrete box girder Nut Tree Road OC received approval from Caltrans since it passes over 1 -80. The bridge was widened on both sides from 12.313 meters of existing width to 31.355 meters in width. As part of our type selection submittal, prepared the General Plan and Estimate for two different widening alternatives to meet the restricted vertical clearance associated with the existing structure. Alternatives considered both an 11 00m II� e 4tl 000 ®® Proposal for Project Study Report Equivalent and Conceptual Engineering Plans for Santa Ana Boulevard Grade Separation Project
