FIDIC definition

What does FIDIC mean? In legal practice, FIDIC usually means the suite of standard‑form construction and engineering contracts published by the International federation of Consulting Engineers (Fédération Internationale des Ingénieurs‑Conseils), rather than the organisation itself. It is an industry term, not defined in legislation or case law. FIDIC contracts (commonly the Red, Yellow, Silver, Green, Gold, Blue and Emerald Books) are widely used on international infrastructure, EPC and design‑and‑build projects. Key legal features include the Engineer’s role as contract administrator and decision‑maker, detailed risk allocation, provisions on variations, payment, extensions of time and claims, strict notice and time‑bar requirements, and tiered dispute resolution using...

This preliminary total is then recalculated at project close, once every quantity has been remeasured, to determine the contract price with accuracy.

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
