Planning advice for contractors

Hong Kong's edition of the NEC4 ECC keeps the standard compensation event procedure and changes much of what sits around it. Weather becomes a list of Observatory warnings, labour shortage becomes an event, and on government contracts several events pay time only while the Project Manager can take six weeks to reply. This guide sets each change against the standard form, explains actual cost on Options A and B, and shows how a disputed event reaches adjudication under Cap. 65

The NEC4 contract read from the planning desk: how the ECC is put together, the main and secondary options in a table each and who does what. Then how time, money and change run back to the Accepted Programme, with one late access event worked through week by week.

NEC4 has six main options, and the one in the contract decides how the Contractor is paid, who carries an overrun and what the programme is asked to support. This guide takes them in pairs: the priced contracts A and B, the target contracts C and D, and the cost reimbursable contracts E and F. For each, what an assessment pays, where the cost risk sits, which clauses only that option carries, and what the planner has to keep current for the money to hold up.

NEC4 Option A and Option C both price the works in an activity schedule, and there the resemblance ends. One pays for completed activities and leaves the overrun with the Contractor. The other pays forecast Defined Cost plus the Fee and settles the risk through the share at Completion. This guide sets them side by side through the programme: what each pays, what each asks of the programme, how compensation events land and where each one goes wrong.

FIDIC does not ask anyone to approve the programme. It asks the Engineer to review it, and gives a period in which to object. Let the period pass and a Notice of No-objection is deemed given, so the defined Programme exists whether anybody meant to create one or not. This guide covers what Sub-Clause 8.3 of the 2017 books requires, how the review works, and when and how the programme is revised.

Delay damages are the part of the JCT to NEC transition contractors think they already understand. The rate is in the contract data and it starts when you are late. What changes is not the arithmetic but the procedure: JCT surrounds the deduction with three notices a contractor can attack, and NEC removes all of them. Plus the conclusion most find backwards, that taking option X7 out of the contract raises exposure rather than lowering it.

Every contractor arriving on NEC has heard that NEC is strict about notices and JCT is relaxed. It is half wrong, in the half that costs money. JCT keeps two notices because it keeps two lists: the extension of time notice carries no sanction, while the loss and expense notice has been held by a court to be a condition of being paid at all. NEC runs one notification and one deadline, and it bars time and money together.

The JCT Standard Building Contract asks for a master programme under clause 2.9, leaves critical paths optional in the Contract Particulars, and only requires an update when you apply for an extension of time. The Design and Build form does not expressly require a programme at all. None of that changes what a retrospective claim has to prove. This is the gap between the contractual floor and the evidential bar, and what to keep so the claim stands up.

JCT vs NEC vs FIDIC, from the planner's side. The three contracts use the same words, programme, notice and extension of time, and give each a different job. This guide sets them side by side, follows one late-access event through each week by week, reads three court cases with the programme at their centre, and sets out how I run the programme when a job moves between them.

A FIDIC extension of time is decided on the programme and the records. This guide takes the 2017 Red and Yellow Books from the planner's side: the Sub-Clause 8.5 grounds and what each carries, the Notice of Claim and fully detailed Claim under 20.2 with the Engineer's 14 days and the late-submission review, the 42 plus 42 days under 3.7, concurrent delay, the programme evidence that wins the days, and what an EU grant adds on funded work.

In June 2026 the High Court refused to enforce a £1.65m NEC adjudication award in Premier Modular v Maidstone and Tunbridge Wells NHS Trust. The legal headline is natural justice. The lesson for contractors is a project controls one. The whole dispute turned on which programme was the Accepted Programme, and the date the claim relied on was never in it. Under NEC, a compensation event is only as good as the Accepted Programme it stands on, and acceptance is a status you earn,

Hong Kong has now used the NEC form on more than 850 public works contracts and, since July 2023, has its own stand-alone edition of the ECC. The Hong Kong Edition re-engineers payment timing, compensation event assessment and dispute resolution, and every change lands on the programme. This is what the 2023 edition changes at programme level, where first submissions fail acceptance, and what a defensible programme contains.

Defined Cost is how NEC4 measures what the work cost the Contractor, and on Options C to F it is also how the Contractor is paid. This guide sets out what it includes under each main Option, what Disallowed Cost takes out, how the Fee is added and how one compensation event is valued, with a worked example. It then shows why real cost still goes unrecovered when the programme and the cost record stop telling the same story.

A practical NEC3 vs NEC4 comparison focused on programme acceptance, treated acceptance, early warning discipline and CE integration, based on NEC’s “Next Generation” white paper.

NEC did not arrive fully formed. It evolved as a deliberate response to the failures of the contracts that preceded it, and every clause in the current NEC4 suite carries the imprint of a specific problem that JCT and ICE could not solve. The history is not background to contemporary NEC practice. It is the explanation of why the controls matter, what the contract was designed to prevent, and how contractors who understand the evolution administer the contract more effectivel

FIDIC vs NEC is not about which contract is better. NEC tests a contractor's programme dialogue, FIDIC its contemporary records. This guide compares the FIDIC 2017 Red Book and NEC4 clause by clause on programme review, revisions, warnings, notices, delay assessment and delay damages, with JCT alongside, and shows where contractors moving between the two forms go wrong.

Social value in construction is the benefit a contractor commits to deliver through a contract, scored at tender and monitored through delivery. This guide covers the law and policy behind it, what scores under PPN 026 from January 2027, why commitments fail, and how jobs and skills commitments are delivered and evidenced on a live project, from the roles in the programme to the records each KPI assessment asks for.

NEC contract administration today still works the way it worked in 1993. A programme gets submitted as a document. The project manager reviews it as a document. Acceptance is recorded as a document. The contractual machinery is electronic in form and paper in function. This is changing faster than most contractors have absorbed, and not in the way the industry talks about.
