An extension of time moves the completion date. It does not, by itself, produce a single euro. This is what an application has to contain, how it is assessed, and what happens when the machinery is not used at all.
An extension of time is the mechanism by which the contractual completion date moves. It is not a favour, it is not an admission, and it is not compensation. Contractors under-use it because they assume the employer knows the works are late for reasons outside their control, and employers mishandle it because refusing every application looks like the safe course. Both assumptions cost money.
This article deals with the mechanics of the application and its assessment. Delay claims generally, including the evidence they require and where they are resolved, are covered in Delay Claims in Cyprus Construction Contracts, and the immediate steps to take when a delay first appears are in Construction Delays: What to Do in the First Two Weeks.
What an extension of time does and does not do
It moves the date for completion, and so removes the period covered by the extension from any liability for late completion. That is its entire effect.
It does not entitle the contractor to be paid anything. Money for the prolonged period is a separate claim, made under a separate clause and proved by separate evidence of the costs incurred. Some events give both time and money, some give time only. The contract says which, and it is worth checking clause by clause rather than assuming the two travel together.
It also does not relieve the contractor of the obligation to proceed with reasonable diligence. Most contracts require reasonable endeavours to prevent or reduce delay, and a contractor that visibly did nothing while the programme slipped will find that reflected in the assessment.
What the extension is measured against
Before any application can be assessed, the original date has to be established. The contract will either state a completion date or fix a period running from possession of the site or from a commencement notice. Where the date runs from an event, confirm when that event actually occurred, since this is frequently in dispute later.
The programme is the second reference point. Where the contract requires a programme to be submitted and accepted, the accepted version is the baseline against which the effect of a delaying event is measured. Where none was accepted, both parties end up arguing about what the baseline was.
What the application has to contain
An application that will survive scrutiny does five things.
It identifies the delaying event specifically, by date and description, rather than by category.
It identifies the clause relied on and shows that the event falls within it.
It shows the effect on the completion date by reference to the programme rather than by assertion. The activities affected, whether they were on the critical path, and the resulting movement of the date all need to be visible.
It states the extension claimed, or, where the effect is still unfolding, the extension claimed so far, reserving the position on the balance.
It identifies the supporting records: instructions, correspondence, site diary entries, weather data where the clause allows for it.
Where the effect cannot yet be quantified, submit within time and say so. Updating an application is easier than explaining why none was made.
Notice, and why it is not a formality
Most extension of time clauses require notice within a fixed period. What matters is how the clause is drafted. Some make notice a condition of entitlement, in which case late notice may defeat an otherwise good claim. Others treat it as a procedural requirement, in which case late notice weakens the claim without extinguishing it, typically because the employer was deprived of the chance to mitigate.
The distinction turns on the words used, and should be established at the start of the project, not after the deadline has passed.
How the application is assessed
The contract names the person who decides, usually the architect, engineer or project manager administering the contract, and often fixes a period within which the decision must be given. The assessment should address entitlement and effect separately, and should give reasons. A certifier who simply refuses without engaging with the analysis invites the argument that the machinery has broken down.
Where two causes of delay operate over the same period, one the employer's responsibility and one the contractor's, the treatment of the overlap is governed in the first place by the contract, and some contracts address concurrency expressly. Where the contract does not deal with it, we are not aware of any Cyprus judgment settling how the overlap is to be treated, so the point should be approached as an open one and argued on the contract and the evidence rather than on an assumed rule.
When the machinery is not used at all
Where an employer causes delay and there is no extension granted and no mechanism capable of granting one, a contractor may argue, drawing on the English common law prevention principle, that the employer cannot then insist on the original date, and that time has become at large, so that the obligation is to complete within a reasonable time. These are arguments from common law reasoning rather than a rule of Cyprus law, and we are not aware of a Cyprus judgment applying either of them. They should be treated as unsettled and run, if at all, on facts that support them. Their practical significance is preventative: an extension of time clause that covers acts of prevention by the employer is what keeps the completion date, and with it the delay remedy, intact.
The consequence of getting it wrong
If an extension that should have been granted is not, the contractor may be treated as in culpable delay and exposed to the contract's delay remedy for a period it did not cause. Where the contract fixes a liquidated damages rate, section 74(1) of the Contract Law, Cap. 149 entitles the employer, even where actual damage or loss is not proved, to reasonable compensation not exceeding the sum named in the contract. The rate operates as a ceiling on recovery rather than as a sum payable automatically: as the Supreme Court put it in Ανόρθωσις ν. Απόλλων (2002) 1 ΑΑΔ 518, adopting Iordanou v. Anyftos, whether the sum is a genuine pre-estimate or a penalty makes no difference to the court's discretion to award reasonable compensation up to the stipulated amount, though a genuine pre-estimate carries weight in fixing it, and nothing beyond the named sum can be awarded. Πιττάλης ν. Ianira Enterprises Ltd (1997) 1 ΑΑΔ 814 remains the leading authority on how the section is applied.
Questions we are asked
Nobody applied for an extension. What is the position?
The completion date remains the original one and the contractor is in delay for a period it did not cause. Correcting that after the event is possible but harder, because the records that would have supported the application were never assembled at the time.
Does an extension of time entitle the contractor to more money?
No. An extension of time moves the date for completion, and so removes the period it covers from any liability for late completion. That is its entire effect. Money for the prolonged period is a separate claim, made under a separate clause and proved by separate evidence of the costs incurred. Some events give both time and money, some give time only, and the contract says which.
What should an extension of time application contain?
Five things: the delaying event identified specifically by date and description; the clause relied on, with the event shown to fall within it; the effect on the completion date demonstrated by reference to the programme rather than by assertion; the extension claimed, or the extension claimed so far with the balance reserved; and the supporting records, such as instructions, correspondence, site diary entries and weather data where the clause allows for it.
What happens if the notice deadline is missed?
It depends on how the clause is drafted. Some clauses make notice a condition of entitlement, in which case late notice may defeat an otherwise good claim. Others treat it as a procedural requirement, in which case late notice weakens the claim without extinguishing it. The distinction turns on the words used, and should be established at the start of the project rather than after the deadline has passed.
How is concurrent delay treated under Cyprus law?
The treatment of two causes of delay operating over the same period, one the employer's responsibility and one the contractor's, is governed in the first place by the contract, and some contracts address concurrency expressly. Where the contract does not deal with it, we are not aware of any Cyprus judgment settling how the overlap is to be treated, so the point should be approached as an open one and argued on the contract and the evidence.
What if the contract gives no way to extend time when the employer causes delay?
A contractor may argue, drawing on the English common law prevention principle, that the employer cannot then insist on the original date and that time has become at large, so that the obligation is to complete within a reasonable time. These are arguments from common law reasoning rather than a rule of Cyprus law, we are not aware of a Cyprus judgment applying them, and they should be treated as unsettled. The preventative answer is an extension of time clause that covers acts of prevention by the employer.
Making an enquiry
