Delay
Analysis

What caused the delay, and how much time it justifies. Forensic analysis to identify, quantify, and explain project delay — with a method that fits the records, the contract, and the forum.

AS-PLANNED vs AS-BUILT FORENSIC AS-PLANNED AS-BUILT Δ EOT PLANNED AS-BUILT COMPLETION
Delay is rarely simple. We establish the cause, the effect, and the entitlement that follows — objectively, and on the evidence.

When a project finishes late, the questions that matter are precise: which events drove the critical path, how much time do they account for, and who is responsible. Answering them well requires a rigorous, transparent method — not assertion.

We select an analysis technique appropriate to the available records, the contract, and the forum in which the issue will be decided, and we apply it consistently. Where time is contested, we address the hard questions head-on: float ownership, pacing, and acceleration.

Our analysis is aligned with the Society of Construction Law Delay and Disruption Protocol and is prepared to the standard expected in formal dispute proceedings.

Methods We Use

Analysis techniques

Prospective or retrospective, the method is chosen to fit the records and the question being asked.

As-planned vs as-built

Comparison of the intended programme against what actually happened to expose where and when the project diverged.

Impacted as-planned

Delay events inserted into the baseline to model their theoretical effect on the planned completion date.

Time impact analysis

Event-by-event modelling on a contemporaneous programme — the preferred prospective method for assessing entitlement.

Time slice / windows

The programme split into discrete windows to track how the critical path and delay evolved over the project.

Collapsed as-built

The "but-for" technique — removing delay events from the as-built record to isolate their net effect.

Causation & float

Rigorous treatment of causation, float ownership, and pacing — the issues that decide contested time.

How We Work

Our approach

A transparent, evidence-led process from raw records to a defensible conclusion.

Records review

Programmes, progress data, and contemporaneous records gathered and interrogated.

Baseline validation

The baseline and updates tested for integrity before any analysis is built on them.

Method selection

The technique chosen to suit the records, the contract, and the forum.

Window analysis

Cause and effect traced through the critical path, window by window.

Findings & opinion

Conclusions on causation and entitlement, clearly evidenced.

What You Receive
