Slide 17
+ Extracurriculars What we learned: The lack of Portland cement
wasnt the only factor Curing time, scrim placement, etc. affected
durability Concrete Canoe 2010 Ex Calce Liberatus

+ Pacific Gas & Electric Entry Engineer program San
Francisco Distribution Planning Rotation Pipeline Engineering
Rotation Distribution Control Center Rotation Started working as a
Gas Distribution Planning Engineer last June
Slide 20
+ Pacific Gas & Electric How do we get gas to our
customers? Backbone transmission Local transmission Local
distribution Service lines Distribution is separated by divisions
and each division has their own hydraulically independent systems
Systems have minimum and maximum design pressures Overview
Slide 21
+ Pacific Gas & Electric Mission Division Five independent
high pressure systems: Fremont/Hayward HP Pleasanton/Livermore HP
San Ramon/Dublin HP South Fremont HP Sunol HP
Slide 22
+ Pacific Gas & Electric SynerGEE Hydraulic modeling
software that takes into account pipe material, diameter, length,
etc. and uses historical load data to predict pipeline pressures
Emergency Operations In case of a leak, dig in, etc., we use
SynerGEE to model whether a pipe can be cut off or needs a bypass
