1. Engineering Introduction Pacific Gas & Electric Company Gas Operations ENGR-10 Guest Lecture November 7, 2013

2. 1 Agenda for today’s presentation Introduction Education: Transferring to Cal Pacific Gas and Electric Company Internship: City of Palo Alto Natural Gas System Fundamentals Engineering in the Natural Gas Industry

3. 2 About my education and beginning of my career UC Berkeley 2 Career 3 Fall 2005 – Spring 2007 Still deciding what to major in: Architecture or Engineering Much cheaper alternative than going straight to university Chabot Community College 1 Fall 2007 – Fall 2009 Graduated with B.S. in Civil Engineering Internship opened many opportunities Led to full time position at City of Palo Alto Began a career at the Pacific Gas & Electric Company

4. 3 Two years at Chabot Fall 05First SemesterSpring 06Second Semester ARCH 2AArch Drawing & Graphics3CSCI 14Introduction to C++4 ENGL 1ACritical Reading & Composition3ENGR 25Computational Methods in Engineering3 HIST 7US History3MATH 2Calculus II5 MATH 1Calculus I5PHYS 4AGeneral Physics5 1417 Fall 06Third SemesterSpring 07Fourth Semester CHEM 31Intro to College Chemistry4CHEM 1AGeneral College Chemistry5 ENGR 36Engineering Mechanics - Statics3ENGL 4Critical Thinking/Writing in Literature3 GEOG 5World Regional Geography3ENGR 22Engineering Design Graphics3 MTH 3Multivariable Calculus5MTH 4Elementary Differential Equations3 PHYS 4BGeneral Physics5MTH 6Elementary Linear Algebra3 POLI 1Intro to American Government3PHYS 4CGeneral Physics5 SPCH 1Fundamentals of Speech Communication3 2325

5. 4 Transferred to UC Berkeley  Took two and a half years averaging 15 credits per semester  Chose to specialize in structural engineering  Course work at Berkeley is much tougher than Chabot -Study hard -Develop good relationships -Take advantage of available resources Schoolwork  American Society of Civil Engineers (ASCE) -Concrete Canoe -Steel Bridge -Career Fairs  Chi Epsilon, National Society of Civil Engineering Honor Society Extracurricular Activities

6. 5 Internships  Interned for the City of Palo Alto while at Chabot AutoCAD experience was invaluable (ENGR 22) Performed mapping and basic surveying for utilities Continued working part time which led to a full time position after graduation  PG&E offers internships 147 college interns during Summer 2013 Mechanical, Civil and Electrical from 60 different colleges ‘Felt part of a team doing important work that’s helping make PG&E the safest gas utility in the country.’

7. 6 Career at PG&E Gas Engineer Management ▪ Codes & Standards – Developing standards and procedures – Lots of research – Problem solving / process improvement ▪ Part of a team – Work on cross-functional projects – Rotational assignments ▪ Many opportunities for growth – Supervisor – Manager – Director ▪ Continue my education – Professional Engineer license – MBA
