Extensions of time

Extensions of time, with the reasoning kept

An award is a number of weeks. What makes it defensible two years later is the sentence explaining how the number was reached, and that sentence is almost never written down.

  • Damages run from the revised completion date, not the original
  • Cap applied where the contract states one
  • Red warning where no certificate of non-completion has been issued

Original completion date7 Sep 2026

Without the six weeks of extension the works would be eight weeks late. The award reduces the damages the employer can deduct from twenty thousand pounds to five.

Where the extension stops the damages clock

The reason an extension matters in money is the completion date it moves.

Damages run against that date, and a week of extension is a week the employer can no longer deduct at the liquidated rate. QScope calculates damages from the completion date after any award, applies any cap, and refuses to let the figure stand while no certificate of non-completion is on the register.

Extensions of time

Time and money are different entitlements

A relevant event under clause 2.29 can carry an extension of time.

  • Thirteen relevant events, each flagged for whether it can carry money
  • A warning when loss and expense is claimed against an event that cannot carry it
  • Notice date, particulars date and award date held separately

Exceptionally adverse weather is a relevant event under clause 2.29 but not a relevant matter under clause 4.21. It relieves the contractor of damages and carries no money.

Extensions of time

Awarded is the only status that moves a date

A claim that has been notified but not decided extends nothing.

  • Revised completion date built from awarded weeks only
  • Contract completion date taken from start date and duration
  • Register prints as a document for issue with the assessment

EOT-02 is claimed at three weeks and has not been decided, so it does not appear in the six weeks applied to the date.

Programme

Where the delay is visible before it is claimed

An extension of time is argued after the event.

  • Contract period taken from the project settings, not drawn by hand
  • Today marked, so the position is obvious without counting
  • Overrun past practical completion stated in weeks

Contract period32 weeks

QScope draws the works against the contract period with today marked, so the overrun that supports the claim is a matter of record rather than reconstruction.

Loss and expense

The money that some of these events carry

An extension of time buys relief from liquidated damages.

  • Prolongation, disruption, overheads and finance charges assessed head by head
  • Each head linked to the delay event it arises from
  • Warning where the event is a relevant event but not a relevant matter

Exceptionally adverse weather carries time and nothing else. Late information is a relevant matter, so the prolongation arising from EOT-02 can be claimed.

Extensions of time

On FIDIC, the same discipline under different clauses

The JCT relevant event has a FIDIC counterpart.

  • FIDIC grounds under Sub-Clause 8.4 alongside the JCT relevant events
  • Notice date logged and the 28 day condition precedent under 20.1 flagged
  • Time and cost carried under the claims machinery, assessed separately

Notice under Sub-Clause 20.1 is a condition precedent in the 1999 edition. Served on day 21 of 28, the claim survives; served late, the entitlement can be lost whatever the delay. Counting is in calendar days. These are published starting points to verify against the Particular Conditions.

Who it is for

One programme, four clocks running on it

You are applying

You claim the time before damages run

You notice delay, name the relevant event and claim the time before the damages clock does the arguing for you.

Applying for payment
the same measurement

You are certifying

You award the weeks and stop the clock

You assess the extension from the other chair, and the completion certificate you issue halves retention and stops the damages clock.

Certifying payment

You are doing both

Your delay is your own money waiting

You run the programme and the money together, and a completion date that slips moves the whole payment tail with it.

Doing both yourself

You are reporting

A late job is a loan running long

You track completion against the facility term, because a job that finishes late is a loan that runs longer than the model.

Recommending a drawdown

The client, the architect and the tenderer are not on this list. They are the people you let in on a link: they see the one document you sent them, answer it, and that answer is written into the record. No account, no licence, no charge, on every plan.

FAQs

The questions this page raises most often, answered without a sales pitch at the end.

No, and it should not. The assessment is a judgement made by a named person under the contract. QScope holds the dates, the claim, the award and the reasoning, and does the arithmetic that follows from your decision.

The list follows the JCT standard forms. Where you are working under an amended contract or a different form, the categories still work as a way of classifying the cause, and the clause numbering will differ.

Yes. It carries the FIDIC grounds for an Extension of Time for Completion under Sub-Clause 8.4 alongside the JCT relevant events, logs the notice date, and flags the 28 day condition precedent under Sub-Clause 20.1 in the 1999 edition. Time and cost are pursued together through the claims machinery rather than as a separate loss and expense head, and dates count in calendar days. The figures are published starting points to verify against your Particular Conditions.

It is cancelled and has to be reissued against the new completion date. QScope flags any damages calculation where no valid certificate is on the register.

Yes, and that is the point of linking them. The heads of claim live in the loss and expense register and each one points back at the event that caused it.
