SOCIETY OF CONSTRUCTION LAW DELAY AND DISRUPTION PROTOCOL - 2nd Edition - February 2017

Sep 12, 2026

Society of Construction Law delay and disruption protocol establishes a structured approach for managing delay events on UK construction contracts. It sets out core principles on entitlement to extension of time (EOT), including programme and contemporaneous analysis, incremental review, and handling concurrent delay. The protocol links EOT to compensation, addresses mitigation and acceleration, and covers both disruption and global claims alongside valuation of variations. Guidance is organized into concept and practical sections for records, procedures, evaluation and calculation of prolongation compensation.

FAQs

What core principles govern analysis of delay events under this protocol?

The protocol emphasizes contemporaneous analysis and discourages waiting to see the full impact of delay events. It also requires maintaining programme and records to support entitlement decisions.

How does the protocol treat extension of time (EOT) in cases of concurrent delay?

It explains that concurrent delay affects entitlement to both EOT and, separately, compensation for prolongation. The protocol distinguishes meaning and handling of concurrent delay to guide evaluation.

How are compensation and disruption claims addressed?

The protocol links EOT to compensation and provides principles for valuation of variations and calculation of compensation for prolongation. It also covers mitigation of delay and loss, acceleration, disruption claims, and global claims.
