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
