Presented at the 2012 Construction CPM Conference, this presentation walks through the challenges of owner/contractor and JV disputes and reviews solutions and prevention techniques using Fuse.
4. 4
Why do Disputes Arise?
• “Planning the work” and “working the plan”
! Causes of failure
• “Unrealistic & inadequate planning” or “Poor Execution”
• Poorly contracted terms, Misaligned expectations
• Loosely defined scope/ High degree of change
! The challenge of CAPEX projects
! Large projects are inherently complex to model
! Gantt charts/CPM tools don’t lend themselves to team insight
! The Solution: Project metric analysis & Forensics
! Pinpoint root-cause of schedule flaws & true risk exposure
! Resolution of cost/schedule/risk/performance issues through optimization
! Study of event interaction using CPM… … to understand significance of deviations from a
baseline for potential use in a legal proceeding.
! Hindsight vs. Foresight approach

Forensics & Metric Analysis
! Objective: to align plan & execution
! Planning
! Quality of schedule basis
! Realism of estimates
! Accuracy of sequence
! Risk-adjusted
! Execution
! Comparison of scenarios e.g. as planned V as built
! Windows analysis e.g. absorption of float
! Non-progress revisions – changes…
! Baseline compliance

14. Case Study #1
Execution Delay Dispute
! Project incurred massive schedule delays
! Disagreement as to root cause of delay
! Ongoing financial exposure was huge
! As expert witness, Acumen asked to:
1. Determine realism of schedule(s)
2. Give insight into highly complex plan
3. Perform schedule risk analysis
4. Pinpoint delay drivers (root cause)
5. Offer acceleration scenarios
15. 15
Schedule Critique
! Developed a library of core metrics to give
insight into schedule basis quality
! Drivers
! Missing logic
! Constraints
! Use of Lags Became the basis
! Effect of the 300
! Negative float metrics built into
! Logic Density™ Fuse
! Float ratio™

16. Fuse Schedule Quality 16
Index™
! Overarching schedule quality score
! Helped with assessing multiple versions
of the schedule
! Enabled trending of schedule quality
! Pinpointed shortcoming by contractor

Logic Density
! Indicator as to the quality of logic
! Highlighted extreme schedule complexity
in early phase of execution
18. 18
Driving Path Analysis
! Pinpoint driving path(s)
! Specific Activity
! Trace forwards, backwards
! Two Activities
! Path between them
! Link visualization
! Show movement
! Highlighted breaks in the
driving path!

Variance Analysis
! Pinpointed changes to plan on monthly basis
! Isolated owner of change
! Determined planned or unplanned

Baseline Compliance™
! Used to determine how close a schedule
was planned and executed against it’s
baseline
! Measure of well the plan was being
executed
! More than just date comparison
! Looked at period-compliance

Summary of Analysis
! Pinpointed specific shortcomings in
schedule
! Determined areas of repeated scope
change
! Determined owner/driver of unplanned

26. Case Study #2
Joint Venture Dispute
• Oil & gas CAPEX project
• Completion Nov 2018 (year later than JV board willing to sanction)
• Pre-FEED already slipped by 6 months
• Determine true first production date
• Understand & agree P50/P75 risk exposure
• Identify scenario to get project back to original target completion
