He is also experienced in the design of li Viii iii special steel erection equipment and precast concrete segmental viaducts; travel- BS/1992/Civil Engineering ing maintenance scaffolding for major bridges; and seismic retrofit and repair of Coursework, Reinforced and Prestressed steel plate girder, truss, and concrete bridges. He has been a project engineer on Concrete Design, Arizona State University highway bridge replacement and rehabilitation (HBRR) projects in California and is PE/1995/Arizona No: 29684 (Civil) familiar with Caltrans local programs procedures. He has supervised preparation PE/1997/California No: 56855 (Civil) 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. ~ Ilf~~~iil i ~ j ~~oii Sen for Bri dge Engineer for the independent design check for two underpass structures.

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 I-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 atthe I-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.

III ~ I ~ II III~uRor 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 boxgirder NutTree Road OC received approval from Caltrans since it passes over I-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 1100mm a . i , II ~ ~ ~ II x „N~~~ ~~~~~~~W ~ ~ ~ I ' ~ III II I I ir~ ~ ~ .
