20.1 CONTRACTOR ’ S CLAIMS

4.20.1 Contractor ’ s claims: Clause 20.1

We have already seen that in the the two Books the Contractor must give his

initial notice of claim within 28 days of the date on which he became or ought

to have become aware of the event or circumstance giving rise to the claim.

We have also see that, should he be late with this initial notice, then under the

express terms of clause 20.1 he is prevented from pursuing any claim in respect

of that event or circumstance.

The initial notice in order to be valid need not take any particular form but

must ‘[describe]

the event or circumstance giving rise to the claim ’. An effective

initial notice thus need not quantify the claim or describe in any detail the

situation or event giving rise to it. The essential purpose of the notice is to

alert the Employer or Engineer to the existence of a situation or event which

the Contractor treats as giving rise to an entitlement; the Employer or Engineer

can then investigate the circumstances as soon as possible.

Assuming that the Contractor does give his initial notice in time, the next

steps in the processing of the Contractor ’ s claim are, in summary, as follows.

The detailed claim

Within 42 days after he became aware, or should have been aware, of the event

or circumstance (or within any extended period agreed with the Engineer or

Employer), the Contractor must submit a fully detailed claim with full supporting

particulars of the basis of the claim and of the amount of time or money claimed.

If a claim event or circumstance has a continuing effect then:

the fully detailed claim is to be considered as interim;

the Contractor is to submit at monthly intervals further interim claims,

giving the accumulated delay and/or amount claimed; and

he is to submit his final claim within 28 days after the end of the effects

resulting from the event or circumstance giving rise to the claim.

The Engineer or Employer ’ s response

Within 42 days of receiving a claim or any further details supporting a previ-

ous claim (or any agreed extension to this timetable), the Engineer or

Employer must respond with approval, or disapproval and detailed com-

ments. He might request necessary further information but he should at least

respond on the principles of the claim within this period.

Determining the claim

The Engineer or Employer is to proceed in accordance with clause 3.5 (see
