PEN'' TAIT & Associates, Inc. <br />On -Call Engineering Services <br />Ali Bastani, PC', GE, PhD I Dead Geotechnical Engineer <br />Dr. Nusuild, an atijunet faculty member at Cal <br />Poly rotational, has room than 20 years or <br />diversified experience in geotechnical 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 />(cantilever, tieback, soil nail, and MSE walls) <br />within and heyond the County of Orange. Be <br />has served die County during various on-call <br />geramhnical engineering contracts since 2006. <br />Dr. Hasten!'$ technical oxilinisc and extensive <br />experience enhances the leant capability to <br />economically address the gcotoehnical aspects <br />of the Type Selection, roundution, and <br />Materials Reports for the County's upcoming <br />transportation projects in u timely manner using <br />tine mast recent FHWA and Caltrans <br />approaches. - <br />Project Management Slope Stability <br />Scisutic Hazard Analysis Sharing <br />Stabilization <br />Foundation Design Landslide Analysis <br />2003 Doctor of philosophy Civil and <br />Environmental Engineering, University of <br />California, Dais <br />1991 Maser of Science Civil and <br />Inivimnmcnut Engineering, University of <br />California, Davis <br />1988 tfachelor of Science Civil <br />Engineering, polytechnic of Tchnu <br />Professional Gcotccboieol Gagineer <br />19991Califanta No. GE 2458 <br />Professional Civil Engineer <br />199510difurnia No. C 53924 <br />Los Patronrs parkway, County of Orange - Rancho Mission <br />Vtejo,CA <br />Ruilt-7olian, Inc. and GIvIU closely collaborated during design and <br />construction of this project. Dr. Bastard served as the project <br />Goolecludcal Engineer of Record Ili charge of the design and <br />construction or approximately S -utile long Los Patrenes Parkway <br />project in Orange County, California. This new roadway Is aligned to <br />extend the Witte 241 Freeway from Oso Parkway to Ortega Highway. <br />Geotecludcal design ofthis pmjcct included ombatknwnt stabiliyation <br />using deep wit mixing against latent spreading, largo mass grading. <br />slope stability of Ili& claffill stop", settlement cwluation, and <br />Ixrvenent design recommendations for appnoximutety 2 million <br />square feet of the proposed road. Conventional methods forpavement <br />design were compared with altcnmtive design recommendations, <br />including soil -cement tmattnent,googrid, fur -depth asphalt concrete, <br />and composite asphalt concrete with aggregate base. Each option was <br />also evaluated for construction cost, construction scheduling, and the <br />estintaed another of trucks required to transport materials. Nosed on <br />this analysis, the preferred recommendation was tine soil•ccment <br />option as it resulted fine estimated $6 million savings or nearly 40 <br />pereon savings over the conventional pavement method. <br />Chlqulta Canyon Bridge, Planning Area 2, County of Orange - <br />Rancho Mission Viejo, CA <br />provided peer review services during design and gcoteclmicai <br />engineering services during construction of file &span, I,400 -foot <br />long, and 80 -loot high bridge. Worked collaboratively with the <br />structural engineer to complete the foundation design. The bridge <br />bents were supported by 9- and I0 -foot diameter CIDH piles while the <br />allotment lvalls were supported oil 1.5 -foot diatucterCIDI-I pics. Bent <br />piles were supported by skin friction within the bedrock and were <br />desilped to resist the potential loads duo to laterad spreading. Bridge <br />foandations wen affected by liquefaction, earthquake -induced <br />scukaienl, and lateral spreading of the underlying alluvial soils. Our <br />analyses included vertical unit lateral capacity design of the large <br />diameter sitars with consideration or lateral spreading. <br />Aiden parkway Gap Closure, lake Forest - City or Luke rarest, <br />CA <br />Project Manager in charge or the geotechnical design and construction <br />quality assurance of Allan parkway Gap Closurc project. This project <br />included appruxinunely one anile of six•lae roadway through natural <br />hillsides of Orange. County. The design efforts included slope stability <br />analyses, evaluation of unsuitable hydro -collapsible alluvium depth, land <br />roadway pavement straoural section. Dr. Nasumi also managed tie <br />geotechnical observation, testing, and material inspection of this APWA <br />and ASCE award-winning project. <br />I WL— <br />'25E-601 <br />Appendix I Page 22 <br />
