North Midland Building Ltd v Cyden Homes Ltd

[2018] EWCA Civ 1744

We first reported on this case in Issue 208. NMBL and Cyden had agreed certain bespoke amendments to the JCT Design and Build Contract 2005, one of which concerned the way in which extensions of time would be dealt with in certain circumstances. The parties had amended clause to include the following:

“3. and provided that

(a) the Contractor has made reasonable and proper efforts to mitigate such delay; and

(b) any delay caused by a Relevant Event which is concurrent with another delay for which the Contractor is responsible shall not be taken into account

then, save where these Conditions expressly provide otherwise, the Employer shall give an extension of time by fixing such later date as the Completion Date for the Works or Section as he then estimates to be fair and reasonable.”

By way of a refresher, the CA provided the following definition of concurrency as given in the case of Adyard Abu Dhabi v SD Marine Services [2011] EWHC 848 (Comm), where Hamblen J (as he then was) said: 

"A useful working definition of concurrent delay in this context is 'a period of project overrun which is caused by two or more effective causes of delay which are of approximately equal causative potency' – see the article Concurrent Delay by John Marrin QC (2002) 18(6) Const. L.J. 436."

Indeed, the CA also noted that concurrent delay was not a concept that was ever considered by the courts until the late 1990’s. Here the works were delayed, and a dispute arose between the parties as to the proper extension of time due to the appellant, NMBL. A major element of that dispute centred on the extent to which Cyden could take clause into account. At first instance Mr Justice Fraser had decided that they could. On appeal LJ Coulson considered the concept of prevention. He referred to the three principles set out in the Multiplex v Honeywell case, namely that:

“(i) Actions by the employer which are perfectly legitimate under a construction contract may still be characterised as prevention, if those actions cause the delay beyond the contractual completion date. 

(ii) Acts of prevention by an employer do not set time at large, if the contract provides for an extension of time in respect of those events. 

(iii) Insofar as the extension of time clause is ambiguous, it should be construed in favour of the contractor.”

Note that what this case does not do, and LJ Coulson made it quite clear that this was not an issue he was considering, is to give a general statement on a contractor’s entitlement to an extension of time in circumstances of concurrent delay. The court was solely considering the bespoke concurrency clause agreed by the parties.

LJ Coulson, agreeing with Mr Justice Fraser, said that: 

“In my view, clause is unambiguous. It plainly seeks to allocate the risk of concurrent delay to the appellant.The consequence of the clear provision was that the parties have agreed that, where a delay is due to the contractor, even if there is an equally effective cause of that delay which is the responsibility of the employer, liability for the concurrent delay rests with the contractor, so that it will not be taken into account in the calculation of any extension of time.” 

In light of the Judge’s conclusion, the only remaining issue was whether there was any reason in law why effect should not be given to that clear provision. NMBL suggested, “boldly” in the words of LJ Coulson, that the prevention principle was a matter of legal policy which would operate to rescue NMBL from the clause to which it had freely agreed. This suggestion was rejected for the following reasons: 

(i) The prevention principle is not an overriding rule of public or legal policy, like for example the rule which strikes down liquidated damages as a penalty.

(ii) The prevention principle is not engaged because pursuant to clause 2.25.5, “any impediment, prevention or default, whether by act or omission, by the Employer” gave rise to a prima facie entitlement to an extension of time. 

(iii) The prevention principle has no obvious connection with the separate issues that may arise from concurrent delay. 

(iv) Clause was designed to do no more than reverse the result in the Walter Lilly case that where delay is caused by two or more effective causes, one of which entitles the contractor to an extension of time as being a relevant event, the contractor is entitled to a full extension of time.  

(v) Clause was an agreed term. This was the most important of all. 

LJ Coulson noted that in the Walter Lilly case, it would have been open to the parties to draft “a proviso to the effect that an extension of time should be reduced if the causation criterion is established”, thereby allowing for a different allocation of risk. That was what the parties here chose to do.The Judge said that:

“A building contract is a detailed allocation of risk and reward. If the parties do not stipulate that a particular act of prevention triggers an entitlement to an extension of time, then there will be no implied term to assist the employer and the application of the prevention principle would mean that, on the happening of that event, time was set at large. But it is a completely different thing if the parties negotiate and agree an express provision which states that, on the happening of a particular type of prevention (on this hypothesis, one that causes a concurrent delay), the risk and responsibility rests with the contractor.” 

The clause here was “clear and unambiguous”. It stipulated that where there is a concurrent delay (properly so called), the contractor will not be entitled to an extension of time for a period of delay which was as much his responsibility as that of the employer. That was an allocation of risk which the parties were entitled to agree. 

Finally, it was suggested that even if clause was enforceable (so that NMBL was not entitled to an extension of time for concurrent delay), there was an implied term which would prevent Cyden from levying liquidated damages. It would be “bizarre” if Cyden could recover liquidated damages for a period of delay for which it was responsible. It could not be said that the liquidated damages flowed from a delay for which the claimant was responsible. This suggestion was rejected for a number of reasons. These included that if clause was a valid and effective clause then it would expressly permit the employer to levy liquidated damages for periods of concurrent delay, because it would not grant NMBL relief against such liability by extending the completion date. Finally, the Judge noted that:

“I do not consider that this result is in any way uncommercial or unreal. A period of concurrent delay, properly so-called, arises because a delay has occurred for two separate reasons, one being the responsibility of the contractor and one the responsibility of the employer. Each can argue that it would be wrong for the other to benefit from a period of delay for which the other is equally responsible. In Walter Lillyand the cases cited there, under standard JCT extension of time clauses, it has been found that the contractor can benefit, despite his default. By clause, the parties sought to reverse that outcome and provided that, under this contract, the employer should benefit, despite the act of prevention. Either result may be regarded as harsh on the other party; neither could be said to be uncommercial or unworkable.”
