Understanding the critical path is fundamental to managing project schedules, protecting completion dates, and establishing the basis for delay analysis and extension of time claims. Our Critical Path Analysis services provide rigorous, defensible analysis of project schedules to identify the critical path, assess float consumption, and determine the impact of delay events on project completion. We combine advanced scheduling expertise with practical construction knowledge to deliver analysis that supports project execution, commercial management, and dispute resolution.
What We Do
Critical Path Identification & Validation
Identify and validate the critical path through rigorous schedule analysis. We review programme logic, assess activity durations, and confirm that the critical path reflects genuine project constraints. We check for logic errors, artificial constraints, and open ends that may distort the critical path. We deliver a validated critical path that withstands scrutiny.Near-Critical Path Analysis
Identify and analyse near-critical paths that pose a risk to project completion. We assess activities with low total float, identify sequences that could become critical if delays occur, and highlight scheduling risks before they materialise. We help project teams understand where to focus attention to protect the programme.Float Analysis & Management
Analyse total float and free float across the programme to understand schedule flexibility and risk. We assess float distribution, identify float consumption trends, and determine whether float belongs to the contractor, the client, or the project. We support float management strategies that protect contractor entitlements and programme integrity.Critical Path Tracing Through Delay Events
Trace the critical path through delay events to establish how delays affect project completion. We analyse how the critical path shifts as delays occur, identify which delay events drive completion date movement, and establish clear causal links between delay events and schedule impacts. We support EOT claims and dispute resolution.As-Planned vs As-Built Critical Path Analysis
Compare the as-planned critical path with the as-built critical path to identify where the project deviated from the baseline programme. We analyse the causes of critical path shifts, identify delay events that drove completion date movement, and establish the factual basis for delay analysis and EOT claims.Concurrent Delay & Critical Path Assessment
Assess concurrent delays and their effect on the critical path and EOT entitlements. We determine whether multiple delay events are simultaneously driving the critical path, assess whether delays are independent or interdependent, and analyse how concurrent delay affects responsibility allocation and entitlements under the contract.Programme Logic Review & Correction
Review programme logic to identify errors, gaps, and weaknesses that affect critical path integrity. We check for open ends, redundant constraints, missing relationships, and logic that does not reflect construction methodology. We recommend corrections and rebuild logic where necessary to produce a programme with a sound, defensible critical path.Critical Path Reporting & Expert Support
Prepare clear, comprehensive critical path analysis reports suitable for project management, EOT claims, adjudication, and arbitration. We present findings in accessible formats supported by schedule extracts and programme outputs. We provide expert witness testimony and respond to challenges from opposing experts.Who We Are
Our Critical Path Analysis team combines certified scheduling professionals with experienced construction practitioners. We understand how projects are built and how schedules behave under real-world conditions. We are experienced Primavera P6 practitioners with a thorough understanding of critical path methodology, network analysis, and the Society of Construction Law (SCL) Delay and Disruption Protocol. We have conducted critical path analysis in support of project management, EOT claims, adjudication proceedings, and arbitration cases across major rail, transport, and infrastructure projects in NSW and Queensland.

What We’ve Delivered
EOT Claim Support
Conducted critical path analysis to support extension of time claims on major rail and infrastructure projects. Traced the critical path through delay events, identified which delays drove completion date movement, and established the factual basis for EOT entitlements. Analysis formed the foundation of successful claim submissions and negotiations.Programme Logic Reviews
Reviewed and corrected programme logic on contractor and client programmes. Identified critical path deficiencies, logic errors, and artificial constraints that distorted schedule analysis. Delivered corrected programmes with sound, defensible critical paths that provided a reliable basis for progress monitoring and delay analysis.Adjudication & Arbitration Support
Prepared critical path analysis expert reports for adjudication and arbitration proceedings. Conducted rigorous as-planned versus as-built analysis and traced the critical path through complex multi-delay scenarios. Provided expert witness testimony and responded to challenges from opposing scheduling experts.Live Project Critical Path Management
Managed the critical path on live projects throughout execution. Monitored float consumption, identified near-critical activities, and provided early warning of emerging schedule risks. Supported project teams with regular critical path reports and recommendations for corrective action.Related Services

Our Approach
- Programme Assessment – We begin by assessing the programme to understand its structure, logic, and quality. We identify any deficiencies that may affect critical path integrity before conducting analysis, and recommend corrections where necessary.
- Critical Path Identification – We identify the critical path through rigorous network analysis. We check that the critical path reflects genuine construction constraints and is supported by sound logic and realistic durations.
- Float Analysis – We analyse total float and free float across the programme to understand schedule flexibility, identify near-critical paths, and assess float ownership. We document float distribution and consumption trends.
- Delay Event Tracing – We trace delay events through the critical path to establish how they affect project completion. We identify which delays drive completion date movement and establish clear causal links between delay events and schedule impacts.
- Concurrent Delay Assessment – We assess concurrent delays and their effect on the critical path and EOT entitlements. We determine whether multiple delays are simultaneously driving the critical path and how responsibility should be allocated.
- Reporting – We prepare clear, comprehensive critical path analysis reports documenting methodology, findings, and conclusions. We present results in accessible formats supported by schedule extracts and programme outputs.
- Dispute Support – We respond to challenges from opposing experts, prepare rebuttal analysis, and provide expert witness testimony in adjudication and arbitration proceedings.
