The NEC4 Brief

Send us Fan Mail We dig into how NEC4 turns value engineering from a vague ambition into a structured process that can reward innovation without undermining price certainty. We compare clause 16 contractor’s proposals with secondary option X21, then pinpoint the contract data choices that decide whether good ideas ever get raised.  • what value engineering means in NEC4 and why scope quality matte...

Send us Fan Mail Disallowed cost is one of those NEC4 ECC ideas that sounds simple until it hits your payment certificate. When you are working under cost reimbursable contracts like NEC4 Option C, Option D or Option E, one challenged line item can turn “defined cost” into a cost you carry yourself. We unpack what disallowed cost really means, why it exists, and how it acts as a commercial control...

Send us Fan Mail Getting an NEC4 activity schedule wrong rarely fails quietly. It shows up as cash flow pain, awkward assessments, and disputes about what “complete” really means. We dig into why the activity schedule is a pricing tool rather than Scope, why NEC expects the contractor to prepare it, and how that single document can either stabilise a project or create friction for months. We compa...

Send us Fan Mail Contracts don’t fail because of one big clause; they slip on dozens of small entries that nobody questioned. We unpack how NEC4’s Contract Data Part One and Part Two turn rules into real delivery, decode those italicised terms that drive behaviour, and show why the first page of options quietly sets your risk, cost and programme story. From X1 inflation and X7 delay damages to X15...

Send us Fan Mail What if the clause you add to gain control actually costs you bidders, time, and money? We dive deep into NEC4’s option Z and show how to make additional conditions work for you rather than against you. Drawing on years of training, live project experience, and industry engagement, we unpack where Z clauses fit in NEC’s modular design and how to decide whether you need them at all...

Send us Fan Mail A schedule on the wall won’t run your project. A living, accepted NEC4 programme will. We unpack how to turn the programme into a central management tool that reflects reality, accelerates decisions, and shrinks the space where disputes grow. From acceptance rules and deemed acceptance to resource clarity and client interfaces, we walk through the mechanics that make NEC’s prospec...

Send us Fan Mail We break down how to assess compensation events on price under NEC, focusing on the dividing date, defined cost, and the difference between assessment by agreement and assessment by default. Two worked examples show why you must compare cost with and without the change, not tender prices against new costs. • definition and purpose of compensation events under NEC • the dividing da...

Send us Fan Mail We unpack how to assess the time element of NEC compensation events, why the dividing date matters, and how to preserve terminal float. We share a three-step method to progress, model impact, and produce clear quotations without relying on end‑of‑project prolongation claims. • defining compensation events and the rights to change dates and prices • why quotations must show alterat...

Send us Fan Mail We unpack how to notify NEC4 compensation events properly, when the PM or contractor must act, and how to use project manager assumptions to price uncertainty without padding. Clear steps, examples, and pitfalls help you move from awareness to implementation without losing entitlement. • defining compensation events and where to find them in NEC4 • why time and cost are assessed t...

Send us Fan Mail We dig into the purpose and practice of NEC early warnings and show how to turn them from admin into a real project tool. Clear notifications, a live register, the right people in the room, and meetings that produce actions, not arguments. • why early warnings are a positive project tool • what to notify and when under Clause 15 • separating early warnings from compensation events...
