<br />Dr. Busuild, an atijunct faculty member at Cal
<br />Poly rotational, has room than 20 Years or
<br />diversified experience in goolechnicall and
<br />earthquake engineering. His experience covers
<br />a wide variety of transportation projects
<br />Including design and construction support for
<br />roadways, bridges, oil([ retaining structures
<br />(catifilever, tieback, soil nail, and MSE walls)
<br />within and hernial tile County of Orainge. Be
<br />has served tile County during various on -call
<br />getamhalical culdnecring contracts since 2006.

<br />Ruill-7ollars, Inc. and GIVIU closely collaborated during design and
<br />construction of this project. Dr. Bastard served as the Project

<br />construction or approximately s-muc long Los Patrenes Parkway
<br />project in Orange County, California. This new roadway Is aligned to
<br />extend the Raide 241 Freeway four Oso Parkway to OrteWi Highway.

<br />option as it resulted fit no estimated $6 million savings or nearly 40
