NEC has no force majeure clause: the phrase doesn't appear in the contract. Instead, the NEC4 ECC uses the prevention event at 60.1(19), plus the Client's liabilities, weather, and termination reason R21, to deal with events that nobody could stop or reasonably foresee.

The result is often better for the Contractor than a typical force majeure clause, as it gives time and money and not time alone. This page compares the two approaches, as part of the wider guide to NEC risk and liabilities.

How NEC differs from a typical clause

PointA typical force majeure clauseNEC prevention at 60.1(19)
TriggerOften a list of named eventsA test, with no list
RemedyOften extra time and relief from liability, without moneyA compensation event: Prices and Completion Date can both change
Who carries the costUsually each side bears its ownThe Client, through the compensation event
Right to end the contractOften after a long stoppage, for either PartyR21: the Client only, when the stated tests are met

The left-hand column describes common drafting in general. Clauses vary, so read any actual clause carefully, particularly if a Z clause has added one to your NEC contract.

The test for 60.1(19)

All of these have to be met for the prevention event to apply:

  1. The event stops the Contractor completing the works, or completing them by the date for planned Completion on the Accepted Programme.
  2. Neither Party could prevent it.
  3. An experienced contractor at the Contract Date would have judged the chance so small that it would have been unreasonable to allow for it.
  4. It isn't one of the other compensation events.

Note the word "stops". Mere disruption and extra cost don't usually count. The guide to the prevention event covers typical examples and failures. Clause 19.1 allows the Project Manager to give an instruction about how to deal with such an event.

Where other extreme events go

EventWhere to look firstReference
Exceptional weatherThe weather compensation event, with data for the place in the Contract Data60.1(13)
Flood or storm damaging the worksUsually the Contractor's liability and insured. Check for a weather event and the Contract Data60.1(13), 81.1
War, riot, radioactive contamination damaging the worksClient's liabilities60.1(14), 80.1
Strikes confined to the Contractor's workforceThe Contractor's risk80.1 excludes them
New legislationOption X2, if selectedX2.1
Events listed by the ClientExtra compensation events in the Contract Data60.1(21) in NEC4 only
The contract becoming legally impossible to performTermination by either PartyR17, 91.5

A single event may touch more than one row. Before you claim prevention, check the others, since 60.1(19) only applies where nothing else fits.

A worked example

A fictional coastal defence scheme. Authorities close the only access road for 10 weeks after an unprecedented landslip on land nobody involved in the job controls. No other route exists. Illustrative only.

  • Does it stop completion by the planned date? Yes, on the Contractor's programme.
  • Could either Party prevent it? No.
  • Chance: the geological reports showed no sign of it, and nothing suggested that an experienced contractor would have allowed for it.
  • Other events? Not a physical condition within the Site, as it happened off Site. So 60.1(12) doesn't apply. Not weather as such.

The Contractor would notify a compensation event under 60.1(19) within the time limit in clause 61.3. It would give an early warning, and it should try to reduce the effect, since the assessment assumes it reacts competently. If the forecast delay had been much longer, the Client could look at R21. See reasons for termination.

Tips for tenderers and Clients

  • Check whether a Z clause has removed or qualified 60.1(19). Some Clients do so to reduce their exposure.
  • If a well-known hazard exists at tender, an experienced contractor may be expected to allow for it. The test is applied at the Contract Date, so what was known then matters.
  • Pandemics and similar events can't be answered in general terms: test the facts of each case against each element, and take advice where the sums are large.
