CASE STUDY

“It's hard to quantify, right now. But at a guess, I'd say it's probably more than 50% faster, at times. It's literally that quick. We've found to be an essential practical tool. We're very satisfied.”

Walsall Council

Disruption meaning

What does Disruption mean?
Disruption describes reduced productivity on a construction project where work is impeded, re‑sequenced or performed inefficiently, so the contractor must deploy extra labour, plant or supervision, or work longer, to meet the programme—even if the completion date does not move. It is distinct from delay: delay concerns time overrun; disruption concerns loss of productivity and increased cost. In UK and Irish construction law, “disruption” is a descriptive term rather than a statutory definition. It is recognised in case law and managed under standard forms (for example JCT, NEC and RIAI) through change/compensation mechanisms or as damages for breach. Typical causes include late information, access restrictions, variations, interference, out‑of‑sequence working and cumulative change. A disruption claim usually seeks recovery of additional costs (inefficiency in labour/plant, supervision, site preliminaries), not liquidated damages or an extension of time unless critical‑path delay is also proven. The claimant must establish a compensable event, causation, and quantification, commonly using measured mile, earned value or resource analysis, supported by contemporaneous records. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, although procedures for pursuing claims (including adjudication under the UK and Irish Construction Contracts Acts) vary. Related terms: delay, prolongation, loss and expense.

Landlord redevelopment works: checklist for pre- and during-works management to mitigate tenant disruption and claims, with guidance on quiet enjoyment, nuisance, rights of light, party walls and remedies

A landlord’s development programme can impact occupants, whether within the premises or on adjacent land. This checklist outlines suggested steps a landlord might take before and during development works, to help minimise potential claims by tenants arising from disruption. What should the landlord do before development starts? The landlord should carefully gauge the potential for dispute by: obtaining a thorough grasp of the planned works programme, covering the physical extent of the works, the site facilities contractors will require, the anticipated timeframe for the project, and the likelihood of noise and dust reviewing the occupational leases in detail: whether the works intrude upon any demised premises. See Practice Notes: Airspace development—guidance for landlords and developers, and Alterations outside the demise—Definition of demised premises if any easements cannot be preserved throughout the course of the development whether any easements and/or rights can be lawfully varied whether an alternative entrance and exit route is available if...

Ireland-Competition dawn raids: preparation, on‑site conduct, privilege protection and post‑raid actions-practical checklist (CCPC and European Commission inspections)

Competition authorities with jurisdiction in Ireland Competition authorities operating in Ireland, chiefly the Competition and Consumer Protection Commission (CCPC) and, where applicable, the European Commission, possess broad powers to carry out surprise inspections, commonly called ‘dawn raids’. Such raids are a central investigative device for enforcing Irish and EU competition law, particularly in matters involving serious and grave breaches of competition rules like alleged cartel conduct, abuse of dominance, and wage‑fixing arrangements. For companies trading in Ireland, the unannounced arrival of the regulator’s authorised officers at their premises without prior warning can be both highly disruptive and risky. Businesses must be dawn raid‑ready to mitigate disruption and to safeguard their legal entitlements while meeting statutory duties throughout an inspection. This Checklist outlines pragmatic pointers to consider before a dawn raid, including forming a dawn raid response team, alongside key priority steps to take during the on‑site raid, managing legally privileged material, and the follow‑up once the raid has ended. Equipping your organisation with dawn raid readiness know‑how and a...

CJEU: Compensation under Regulation (EC) No 261/2004 requires presenting at gate check-in; online check-in alone insufficient (Laudamotion v flightright)

Laudamotion GmbH v flightright GmbH, Case C-474/22, ECLI-EU-C-2024-73 What are the practical implications of this case? In Laudamotion GmbH v flightright GmbH (Case C-474/22; ECLI-EU-C-2024-73), the consequences for air passengers covered by Regulation (EC) No 261/2004, the Air Passenger Rights Regulation (the ‘Regulation’), are far-reaching. Air passengers often find themselves already informed that a flight will run three hours late. Such delays are routine within aviation and may stem from technical problems with the aeroplane, strikes, or any other cause. When, because of that known delay, an air passenger no longer wishes to travel—whether because they know they will miss their meeting, as occurred in the dispute, or for any other reason—it is perfectly ordinary for them not to go to the gate to check in; and, where the delay is flagged much sooner, not even to set off for the airport for a flight they do not plan to take. The practical stakes for those within the scope of the Regulation are therefore considerable. Such disruption may...

Protest injunctions against persons unknown: no dispensation under CPR 6.16; alternative service and Article 10/11 proportionality (England and Wales)

Birmingham City Council v Persons Unknown (Re Protests in Support of the Bin Workers’ Strike) [2026] EWHC 373 (KB) What are the practical implications of this case? The ruling confirms that public bodies may secure protest injunctions against ‘persons unknown’ when there is cogent proof of mounting, intentional disruption, provided procedural protections are scrupulously followed. By declining to waive service, the court emphasised that CPR 6.16 demands truly exceptional circumstances. Accordingly, claimants should implement robust alternative notification measures and adhere closely to CPR 6.15, with explicit provisions on deemed service and liberty to apply. Injunction terms should be bounded by time and geography, and supported by precise evidence addressing trespass, private nuisance and public nuisance. On substance, the decision clearly distinguishes peaceful assembly from intentional blockage of access or critical services. Although Articles 10 and 11 are in play, persistent, targeted interference with public services is unlikely to sit at the heart of the protected rights...

Delay Damages and Extensions of Time in Energy Construction: FIDIC, NEC, MF/1, IChemE and ICC—Risk Allocation, Liability Caps and Sectional Completion

Even with advanced procurement techniques, scheduling tools and project management applications, construction schemes can still run late and overrun. Any slippage triggers extra cost. This Practice Note explores the delay damages regime designed to safeguard an employer if delay occurs, highlighting the relevant FIDIC clauses and other standard form contracts used in the energy sector that address delay damages. See also Practice Notes: Delay and disruption in construction projects and Time and money claims. The importance of time in energy projects Construction and energy contracts devote substantial attention to time, particularly setting a completion date. Most building contracts provide for delay damages (also termed liquidated damages or liquidated and ascertained damages (LADs)). The core concept is that, on specified breaches by the contractor—commonly failure to complete on time, but potentially performance shortfalls—agreed damages become payable to the employer. Fixing those sums before contract award seeks to avoid protracted and costly proceedings required to demonstrate actual loss...

PRACTICE NOTES
Time bars and conditions precedent in construction contracts: notice obligations, JCT/NEC/FIDIC/ICC regimes, case law, prevention principle, exclusive remedies and practical guidance

Conditions precedent in standard form contracts In many construction contracts, a party looking to pursue a claim under the contract must comply with a specified process as prescribed by the terms. Typically, the claiming party is required to serve a particular notice, which may then be followed by a further notice and/or fuller particulars, on the other party and/or the contract administrator, in a set form and meeting stated requirements as to content and layout. Frequently, these notice clauses also include a so‑called ‘time bar’, meaning the notice(s) must be given within a defined period specified by the contract. Where the time bar is expressed as a condition precedent, any failure to follow the contractual steps results in the claiming party losing its right to advance the claim, regardless of how compelling the underlying case might otherwise be, and even where the claim would otherwise be well‑founded. The inclusion of such time‑bar provisions has become increasingly prevalent, and they now feature in some standard form contracts (see Conditions precedent...

Scott Schedule for construction claims: misrepresentation damages, variation-related prolongation and disruption, and interest on late interim payments—template with claimant, defendant and judge sections

Damages claim for misrepresentation, at common law and/or under the Misrepresentation Act 1967, s 2 The Claimant entered the contract in reliance on the Defendant’s assurances that every parcel of land needed for the scheme had already been secured and that former local residents supported the project. See Schedule X. The Claimant says this amounted to fraudulent misrepresentation: the assertion was untrue and the Defendant knew it. Alternatively, the statement is said to have been made negligently, as the Defendant lacked any reasonable basis for believing it was accurate. When the Contract was executed, a number of local residents refused to sell their land, and residents carried out protests within the Site for the duration of the works, which halted operations at the protest locations...
