Transitioning from Area to System Based ConstructionPresented by: Sean PrzyCOAA Workface Planning ForumCalgary, Alberta December 1 2010

OpeningSystem Based Construction- The challenges common to mostprojects can be anticipated.- Because these challenges can beanticipated, they can be planned for.2

Presentation OutlineDefine Area vs. System based Construction.Why & how the transition occurs. Is transitioning the problem?What are the significant challenges we face during system construction?• What are some of the mitigating actions we may take to reduce their impact.3

Common Challenges During System ConstructionQuality IssuesLate Engineering & MaterialsProductivity IssuesProgress & Productivity Measurement8

Quality IssuesThe ChallengeConstruction DeficienciesVendor & Fabrication DeficienciesEngineering DeficienciesDocumentation / Turnover DeficienciesPotential SolutionsRegular and meaningful Quality Audits. Identify trends early.Use of the “Scorecard” to not only verify progress but to perform targetedinspections during construction through In-Process Verification.Source Inspection with early involvement from Operations personnel.Early identification of RFI during Work Face Planning & Packaging.Early system definition which allows for effective packaging of qualityrecords for system turnover.9

Late Engineering & MaterialsThe Challenge• Capacity to absorb late engineering changes or material deliveriesdecreases substantially.Potential Solutions• Early identification of pending engineering changes or late materialdeliveries to permit recovery planning.10

Productivity IssuesThe ChallengeIncreased Travel & Support Requirements.Increased Safety Awareness RequirementsMotivational & Territorial IssuesPotential SolutionsFind a middle ground between system priorities and area based efficienciesthrough effective Field Installation Work Packaging. Package deficiencywork in same manner as original commodities.Work under system priority only as needed and accept that productivity willbe impacted and plan accordingly.Integrated planning that anticipates energized systems, hydro test exclusionareas, etc.Work Packaging during System Based Construction adhering to geographicboundaries used during Area Construction.11

Progress & Productivity MeasurementThe Challenge• Rate of progress drops significantly during system construction.Potential Solutions• We need to take a closer look at how we measure progress up to andduring this stage of the project. Anticipated work is being performedhowever there is no progress to earn against.12

ClosingThese challenges are real andcannot be eliminated.We can, however plan for themand manage our way throughthem.13
