EPC contract meaning

What does EPC contract mean?
An EPC contract (engineering, procurement and construction) is a turnkey design-and-build agreement under which a single contractor agrees to deliver a fully operational facility by a fixed date and price, taking responsibility for design, procurement, construction, commissioning and performance. In practice it is used on energy, renewables, process and infrastructure projects to provide “single point” risk allocation and bankability for project finance. The term is descriptive market usage rather than a concept defined by legislation or case law. Typical features include: lump-sum price; fixed completion date; performance guarantees; liquidated damages for delay and under‑performance; capped liability; limited relief events (force majeure, change in law, unforeseeable ground conditions where agreed); strict design responsibility and interface risk; testing and commissioning; defects liability period; security (parent company guarantees, performance bonds), step‑in rights and collateral warranties. Standard forms often used or adapted include FIDIC Silver Book and IChemE (turnkey) forms; NEC is sometimes amended to approximate EPC risk allocation. Usage and core risk allocation are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, though local law affects implied terms, limitation periods, security instruments and procurement rules. EPC is distinct from lighter “design and build”, offering more comprehensive performance obligations.

Seller’s solicitor checklist for selling a registered freehold residential property—vacant possession or subject to tenancies (England and Wales): from initial instructions to post-completion

Use this checklist when representing the seller in the disposal of a registered freehold residential property, whether offered with vacant possession or burdened by a lease or multiple leases. It is not comprehensive and will not address every eventuality in every transaction. You should always consider if there are additional matters that require attention. It does not purport to be a complete guide for every case. Preliminary matters Have you taken instructions from the client? Robust due diligence and effective transaction management depend on a clear grasp of the seller’s objectives and the proposed sale terms. Obtain full instructions, and clarify any elements of your brief that are unclear or out of the ordinary. Consider whether further specialist input is required; for example, planning advice where completion is conditional upon planning permission being secured. The table below sets out some of the principal points on which instructions should be obtained at the outset. This list is not comprehensive, and you may need to request information about additional...

TCC (England and Wales): Prior notice under 43.1A was a condition precedent to termination; 'absolute discretion' concerned starting the process only (Interserve v Hitachi)

Original news Interserve Construction Ltd v Hitachi Zosen Inova AG [2017] EWHC 2633 (TCC), [2017] All ER (D) 82 (Nov) What are the practical implications of this case? Although the outcome rested largely on the parties’ bespoke terms, the case underscores the need to examine termination provisions with care both when contracting and before attempting to terminate. It also indicates that, when interpreting the parties’ chosen wording, the court is unlikely to construe it in a manner that fails to give operative effect to expressions such as ‘subject to’. What was the background? Hitachi, the EPC contractor for an energy from waste plant in Worcestershire, engaged Interserve as sub‑contractor. Dissatisfied with Interserve’s performance and delay, Hitachi served a notice under sub‑clause 43.1 of the sub‑contract, invoking grounds (h) and (q). Those grounds provided that, if Hitachi failed to proceed regularly or diligently with the works or committed a material breach: ‘…then, subject to Sub‑Clause 43.1A and without prejudice to any other rights or remedies which’...

Compiling the construction contract bundle for execution: hierarchy, standard forms (JCT/NEC/FIDIC), bespoke and ancillary documents

This Practice Note sets out, step by step, how to assemble all the components of a construction contract ready for execution from the outset. In the haste to start the works, gathering the complete suite of documents that constitute the contract is sometimes overlooked, or not collated promptly. At times, works even commence before negotiations are concluded or the agreement executed, typically under a letter of intent (see Practice Note: Letters of intent—construction). This is generally unwise; it is essential to finalise the contract and to ensure a full set of documents is compiled and readily accessible to each party at all times, to support efficient and consistent contract management and administration, and to ensure issues and potential disputes can be handled effectively and smoothly throughout the works. General considerations Construction contracts are often extensive and voluminous, containing numerous technical and commercial schedules as well as a lengthy main body of conditions and contract particulars. The precise documents required to create the construction contract will be shaped by...

FIDIC Red Book 2017 v NEC4 ECC: A practitioner’s guide to key differences in risk, administration, pricing, payment, delay/EoT, claims, termination and dispute resolution

This Practice Note sets out a comparison of headline aspects of the FIDIC 2017 and NEC4 suites, highlighting similarities and distinctions across their principal features. It specifically concentrates on the NEC4 Engineering and Construction Contract (ECC) and the FIDIC Red Book 2017 (Red Book), used primarily where the Contractor constructs to the Employer’s design in practice (although, where the scope includes any Contractor design, the Red Book accommodates this). For commentary on the 1999 edition of the FIDIC Red Book, see Practice Note: FIDIC 1999 and NEC4 contracts compared. Overall philosophy FIDIC FIDIC contracts are the leading international standard-form construction agreements. They are often described as ‘written by engineers, for engineers’. The suite is also recognised for balanced risk distribution, with liabilities generally allocated to the party best able to manage them (the EPC/Turnkey variant, widely referred to as the Silver Book, is something of an exception). As one would expect from documents devised by engineers, the Engineer has a central function in a number of the...

FIDIC 1999 Yellow v Silver Books: design-build/EPC comparison, project suitability, risk allocation, administration, price and payment, claims/DABs, testing and third-party property damage

This Practice Note reviews the Conditions of Contract for Plant and Design Build 1999 (widely known as the FIDIC Yellow Book 1999) and the Conditions of Contract for EPC/Turnkey Projects 1999 (the FIDIC Silver Book 1999). Both are intended for scenarios where the Contractor, rather than the Employer, undertakes the design of the Works, but there are important differences, which are outlined in this Practice Note and considered at a high level. For deeper analysis of each form, see Practice Notes: FIDIC contracts—introduction to the Yellow Book 1999 and FIDIC contracts—introduction to the Silver Book 1999 for background and context. New editions of the Yellow and Silver Books were issued in December 2017. For more information, refer to Practice Note: FIDIC contracts 2017—what’s changed? [Archived]. These materials provide helpful orientation too. What types of projects are the contracts suitable for? Although both contracts envisage the Contractor being responsible for carrying out all, or the vast majority, of the design, and both are fixed price 'lump sum' contracts, that...
