Disruption and prolongation claims

Productivity and prolongation analysis grounded in project records.

Assess productivity losses, disruption, resource impacts and prolongation costs through coordinated programme, contractual and quantum evidence.
Overview

Time and productivity impacts must be separated before they can be valued.

Disruption concerns loss of productivity, while prolongation concerns the cost of remaining on the project longer. Either may occur without proving the other.

A defensible assessment selects the best available comparison, tests data consistency, considers alternative causes and explains the bridge from operational impact to claimed cost.

Quantification is reconciled to labour, plant, site-overhead, payment and accounting records, with contractual entitlement, notices, compensable periods and potential double recovery examined separately.

How the work is approached

A structured and auditable process.

01

Define the alleged disrupted work and period.

02

Assess data quality and select comparison periods.

03

Normalise scope, conditions and resource inputs.

04

Quantify productivity difference and test competing causes.

05

Separate disruption from critical delay and prolongation.

06

Test contractual recovery and reconcile each cost head to project records.

07

Present calculations with transparent assumptions.

Frequently asked questions

Practical answers before the engagement begins.

Is a measured mile always required?
No, although a reliable measured mile is often persuasive. Where no suitable unaffected period exists, other project-specific or industry-supported approaches may be considered with clear limitations.
Can total cost prove disruption?
A total-cost approach is generally vulnerable unless strict prerequisites are satisfied. More focused cause-and-effect and productivity evidence is usually preferable.
Does an EOT prove prolongation entitlement?
Not automatically. The compensable period, contractual risk allocation and actual additional cost still require assessment.
