Concrete Canoe – 2009 Bear Area
+Extracurriculars
First canoe that did not use Portland cement in the structural mix Geopolymer concrete
Concrete Canoe – 2010 Ex Calce Liberatus
+Extracurriculars
Unfortunately…
Concrete Canoe – 2010 Ex Calce Liberatus
+Extracurriculars
What we learned: The lack of Portland
cement wasn’t the only factor
Curing time, scrim placement, etc. affected durability

+Bay Area Air Quality Management District Local government agency Air Quality Engineer
Evaluated industrial sources and created permit conditions to ensure regulatory compliance
Conducted Health Risk Screen Assessments with air quality modeling program
+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
+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
+Pacific Gas & ElectricMission Division
Five independent high pressure systems:
Fremont/Hayward HP
Pleasanton/Livermore HP
San Ramon/Dublin HP
South Fremont HP
Sunol HP
+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
