LDs meaning

What does LDs mean?
LDs means liquidated (and ascertained) damages: a pre‑agreed sum payable for a specified breach, most commonly delay to completion, used widely in construction and other commercial contracts. It is a descriptive, industry term rather than a statutory one; enforceability is determined by case law on penalty clauses. Typical features include a stated daily or weekly rate (often with a cap), a defined trigger (missed milestone or completion date), and procedural requirements (notices, certification, and deduction/payment mechanics). LDs allocate risk and provide cost certainty by avoiding proof of actual loss. They are usually the exclusive remedy for the identified breach unless the contract preserves the right to claim general damages. Across England & Wales and Northern Ireland, LDs are enforceable if they protect a legitimate business interest and are not out of proportion to it (Cavendish v Makdessi; ParkingEye); extravagant or unconscionable sums are penal and void. Scots law applies a closely analogous penalty doctrine. In Ireland, courts apply the Dunlop line of authority and increasingly consider “legitimate interest”, with Cavendish persuasive. Also known as lads. Related terms include delay damages (NEC) and liquidated damages (JCT/FIDIC).

Liquidated damages in construction: drafting and enforcement—penalties post-Makdessi, uncertainty, prevention, procedures, capping, sectional completion/partial possession, sub-contracts, and JCT/NEC/FIDIC guidance

This Practice Note sets out the concept of liquidated and ascertained damages (LADs/LDs) and their role within building contracts. It explains how these provisions function and why they are used. Distinguishes liquidated from general (unliquidated) damages; Reviews enforceability and common challenges, including penalty arguments; Addresses setting the LADs figure, caps, and the dangers of stating “nil” or “N/A”; Refers to case summaries in a related case law Practice Note. What are liquidated damages? Where parties to a construction contract agree LADs, they pre-determine a fixed sum payable if a specified breach occurs. These provisions are also known as liquidated and ascertained damages, with the acronyms “LDs” and “LADs” used interchangeably. When liability for LADs arises, the amount is usually payable by the contractor to the employer, or the employer may deduct it from sums otherwise due to the contractor...

PRACTICE NOTES
Time at large in construction: causes, prevention principle, extension of time, consequences for liquidated damages, reasonable time, time bars, concurrent delay, and drafting to avoid time being set at large

This Practice Note explores the notion of 'time at large' in the context of completing works under a construction contract, setting out what the term signifies, how it can arise, and the consequences of time becoming at large (including what amounts to a 'reasonable time' for completion)... What does 'time at large' mean? Ordinarily, construction contracts require the contractor to finish the works by a stated completion date (or within a defined timeframe). If that deadline is not met, and the contract does not permit an extension to cover the relevant cause(s) of delay, the contractor will typically be liable to pay liquidated damages (known as LADs or LDs) to the employer. Where, however, the provisions dealing with time for completion are absent or deficient, so that the employer cannot insist on completion by a particular contractual date, time is said to be 'at large'. When time is at large, there is no enforceable completion date under the contract, and the contractor is then bound only by an...
