Where the contract divides the works into sections, each section carries its own completion date, its own damages rate and its own entitlement to relief. Delay to one section is not delay to the project, and conflating them is a frequent and expensive error in extension of time claim preparation.
The arrangement is common on phased residential schemes, on fit out packages and wherever an employer needs part of the building before the rest.
What sectional completion does
It splits the works into parts, each with its own date for completion and its own consequences for being late.
Practical completion, damages, retention release and defects periods then run separately for each section.
That is administratively heavier than a single completion date and it is what the employer is paying for.
Sections against phased possession
Sectional completion is set up in the contract from the start, with sections defined and dates fixed.
Phased or partial possession happens during the works, by agreement, and the consequences differ.
Treating one as the other is a common error and it affects damages, retention and insurance, so the distinction is worth establishing before anything else.
Delay to one section
An event delaying one section may have no effect on the others, which means the extension and the damages position are section specific.
The analysis therefore has to identify which section’s governing chain was affected, rather than the project’s.
Claims that present a single project level delay position on a sectional contract frequently cannot be assessed at all.
Events affecting several sections
Some events affect everything: late design information on a common element, a site wide access restriction, a statutory issue.
Each section then needs its own assessment, because the effect may differ depending on where each section had reached.
That is more work and it is the work the contract has created by dividing the project.
Damages by section
Each section usually carries its own rate, and the rates are frequently different, reflecting the value of each part to the employer.
Deductions are made section by section, which means the procedural requirements have to be met for each.
A deduction made against the wrong section, or without the certificate for that section, is challengeable on its own terms.
Where the sections interact
Sections are rarely independent in construction terms: one has to be built before or alongside another.
Delay to an early section therefore frequently delays a later one, and the causal chain runs between them.
Showing that chain is part of the analysis and it is why the programme needs to show the sections separately and their links.
Programmes for sectional contracts
The programme should identify each section and show its own governing chain, which many programmes on sectional contracts do not.
Without that, no section specific analysis is possible and the claim is limited to what the dates alone show.
Setting it up correctly at the start costs a day and saves a great deal later.
Retention and defects by section
Retention release and the defects period run from each section’s own completion, which means several timetables running at once.
Those timetables are frequently missed, with retention held long past the point at which it was due.
A simple schedule of section dates and consequent dates prevents most of it.
What the employer has to get right
Certificates for each section, at the right time, in the right form.
Damages applied at the correct rate for the correct section, with the payment notice requirements met.
And the extension of time machinery operated section by section, which is where employers most often fall behind.
What the contractor has to get right
Notices identifying which section is affected, because a notice about the project may not serve for a section.
Programme and progress records at section level, so the effect can be shown where it occurred.
And a claim structured by section, which is harder to write and far easier to assess.
Where the sections were never properly defined
It happens: the contract particulars refer to sections that the drawings and the works information do not clearly delimit.
That ambiguity affects damages as much as time, and it is worth identifying early rather than arguing about at completion.
Where the definition is genuinely unclear, the position needs advice rather than a surveying assumption.
Settling a sectional dispute
Sections can be settled separately, which sometimes allows the straightforward ones to be closed while the difficult one continues.
That is frequently the fastest route to releasing money and reducing the scope of the argument.
It needs the claim to have been structured by section from the start, which is the practical reason for doing so.
Keeping the section dates visible
A single schedule listing each section, its completion date, its damages rate, its retention release date and the end of its defects period, kept where the whole team can see it.
That one page prevents most of the administrative failures on sectional contracts, on both sides, and it takes an hour to prepare.
It also makes the claim and the defence quick to put together, because the dates that everything else hangs on are already established and already agreed.
Where it fits
The sectional position is established before any analysis, because it determines how many analyses there are.
Where damages have been deducted against a section, the mechanics are worth checking through pay less notice review in parallel with the time claim.
Administering the section dates during the works belongs with contract administration rather than with claims work.
Where the sections were run as a single project on paper and separately in reality, the gap between those two accounts is usually where the dispute sits, and it is worth closing before completion rather than afterwards.
Running late with nobody agreeing why?
Extension of time claim preparation sets out the events relied on, their effect on the programme and the contractual route to relief, in a form that can be assessed rather than argued over.
