Outline
1. What I learned in six months at PG&E
2. Challenges
3. Areas to improve & proposed methods
4. What’s next? Going upstream & understanding integrity
management
5. Goals for my next rotation
Pipeline Engineering & Design Group – March 6, 2015
Shorts assigned to be IFC’d by January 2015 = 20
Shorts IFC’d by January 2015 = 2
Shorts IFC’d to date = 3
Total # shorts contribution = 5

L-105A valve replacement in Oakland
Pipeline Engineering & Design Group – March 6, 2015
Limited funds &
restricted compliance
date prevents
compiling project with
neighboring work
12 kV electric line
creates limited space
to install 30” TDW on L-
105A

L-132 pipe replacement in SF
Pipeline Engineering & Design Group – March 6, 2015
Replace 2.7’ IM flagged D
pipe
ANSI 300 upgrade of pipe
assembly – should be
sufficient pressure bounds
contradictory dimensions on
As-builts
Overall recommendation to
reduce short pipe
replacements by expanding
future hydrotests
STAGE 1
IM sifts through PFL and prioritizes
flagged segments
STAGE 2
Engineering validates data &
scope and determine plan
of action
STAGE 3
Project management assigns job #s,
order #s, & stakeholders
STAGE 4
Engineering & Estimating 60/90/IFC
drawing review process
STAGE 6
PM, Construction & Engineering

Goals for Integrity Management
PED project forecast
Address IM
flagged pipe
Public & Employee
Safety, Engaged
Employees
Improve scopes for
pipeline projects
Understand how pipe
segments are flagged
given available records
Learn to discern what
projects to prioritize
based on IM industry
studies
Explore the
methodologies to
mitigate risk and refine
where necessary
Nick Jordan for his support with the L-105A Oakland project,
valuable feedback & insight, and field exposure
Shiela Moore for document research recommendations
George Farage for thorough review of PDS documents upon
projects assignments, helpful suggestions on project workflow
efficiency and overall investment in my professional growth
Ed Stracke for grilling me with questions
Neil Flemmer for supporting shorts projects, feedback on design’s impact on construction
Francisco Castro for the opportunity to learn & contribute to the
PED group
