Expert Insights: David Moreland Presents on Concurrent Delay in Construction Projects

We’re pleased to share David Moreland’s comprehensive presentation on Concurrent Delays in Construction Projects, delivered at the Construction Contracts & Claims Conference hosted by CMG Events in Dublin on 4th July 2024.

Understanding a Complex Construction Challenge

As a Chartered Civil Engineer and specialist in delay analysis, David tackled one of the construction industry’s most contentious issues: when both employer and contractor events cause project delays simultaneously. His presentation provided crucial insights into this frequently misunderstood concept that can significantly impact project outcomes and financial settlements.

Key Topics Covered

David’s presentation explores the fundamental principles of delay analysis, starting with critical path methodology and progressing through the complexities of concurrent delay scenarios. The session examines:

  • Critical Path Analysis – The foundation for understanding project delays and their impacts
  • Defining Concurrent Delay – Moving beyond misconceptions to understand when delays truly occur concurrently
  • Extension of Time vs Prolongation Claims – The crucial distinction between time relief and financial compensation
  • Case Law Analysis – Real-world applications through the Thomas Barnes vs Blackburn case study

Practical Insights for Industry Professionals

One of the presentation’s most valuable contributions is David’s emphasis that “true” concurrent delay is “frequently talked about but rarely true.” Through detailed case studies and gantt chart examples, he demonstrates how careful analysis often reveals that delays attributed to concurrency are actually sequential or only one event truly affects the critical path.

The presentation also covers the landmark Malmaison approach and the “Time No Money” principle, explaining how Contractors may receive extensions of time without corresponding financial compensation during periods of concurrent delay.

Expert Analysis of Recent Case Law

David provides an in-depth examination of the Thomas Barnes & Sons PLC v Blackburn case (2022), illustrating how courts approach concurrent delay disputes in practice. This case study demonstrates the difference between theoretical concurrent delay and the factual analysis required to determine actual project impacts.

Why This Matters

For construction professionals, understanding concurrent delay is essential for:

  • Accurate project programming and risk management
  • Proper extension of time claims and assessments
  • Effective dispute resolution and early settlement of issues
  • Improved project and programme management strategies
