Every answer and its explanation appears here once you have finished the path. Each one then links to the matching glossary entry, where the concept is set out in full with its worked example.
1. A localized settlement of a warehouse floor slab appears six weeks after the maintenance period expired. It affects neither structural integrity nor use of the building. What is left?
Nothing from either regime: the maintenance period is closed, the decennial requires impairment of structural integrity or use, and a poured slab is not a separable element for the guarantee of proper functioning
Between what the maintenance period covered and what the legal guarantees cover lies a space nobody protects any more, and this defect falls squarely into it: too minor for the decennial, not separable for the guarantee of proper functioning, and six weeks too late for maintenance. The answer on the guarantee of proper functioning keeps its duration and forgets its condition, which is not the absence of severity but the separable character of the element. The one assessing the decennial over time describes reasoning judges sometimes apply to evolving defects, and extends it to a settlement nothing says will progress. The answer starting the period at the lifting of reserves picks the wrong anchor: it runs from acceptance, and that is what makes expiry so quiet, it arrives on its own by the passage of time.
Glossary entry · garantie-subsequente2. The retention for a tranche was released when its maintenance period expired. Six weeks later, a defect appears on that tranche. What has changed, beyond the cover itself?
The balance of power: while the retention was held, the contractor came back because it wanted its money. Released, it now comes back only under legal obligation, which must be reminded then enforced
The retention is the owner's only concrete lever, and releasing it reverses the balance of power without any clause having moved. The answer seeing only a payment mechanism is legally accurate and practically wrong, which makes it instructive: rectification obligations do survive release, but enforcing them now takes letters, time and sometimes a third party, where an unpaid balance used to be enough. The one shifting the burden of proof invents an evidentiary effect the retention never had. The one making the defect latent conflates unrelated notions: apparent and latent are assessed AT ACCEPTANCE, and nothing happening afterward recharacterizes a defect.
Glossary entry · cautionnement-surety-bond3. On works accepted in three tranches, water ingress appears at the junction between a tranche whose maintenance period has expired and a tranche still under cover. What decides?
The side on which the defect is established to sit, each tranche carrying its own expiry date: this is the counterpart, at the other end of the period, of the coverage gap that acceptance in tranches produces at its start
A split decided for scheduling reasons produces as many calendars as tranches, and the works end up partly inside and partly outside. At the junction, characterization becomes a question of money rather than of engineering. Unifying the periods on the final tranche's acceptance describes what it would have been sensible to negotiate rather than what a policy counting by accepted section says. The one invoking interpretation in favor of the insured calls on a rule that applies to an AMBIGUOUS clause, not to an uncertain fact: here the wording is clear, it is the location of the defect that is not. The answer relying on the date of discovery assumes settled what is at issue, since at that precise moment one period is closed and the other is running.
Glossary entry · assurance-construction4. At the expiry of a maintenance period, a defect is poorly documented. Why, and how is that different from a lack of diligence?
The site teams left long ago: the works manager has gone, the contractor has reassigned its people, and the works are run by people who never saw how they were built
The difficulty is not ill will but memory: nobody was there when the thing was built, and a defect is documented first by the recollection of those who saw the erection. That is why documentation of rectification, done at the time, is used here for the first time. The answer on archiving names a real administrative nuisance, far easier to overcome than a team's departure. The one treating late notification as forfeiture draws too broad a consequence from a true rule, and above all reverses the order: it is because the file documents poorly that it is notified late. The answer giving the operator an interest in staying quiet describes a calculation that sometimes exists, and does not account for the more numerous cases where it documents in good faith what it does not understand.
Glossary entry · declaration-de-risque5. A review is carried out one month before a maintenance period expires. What does it allow that cannot be recovered afterward?
Deciding, reserve by reserve, which ones to have carried out while a lever still exists, and inspecting the works with someone who saw the site while any such person remains
What the review produces is neither legal nor insurance related, and that is what makes it easy to neglect: it creates no rights, it uses the ones about to lapse. The two levers it draws on, the retention still held and the people who saw the site, both disappear, and at roughly the same time. The answer on interrupting the period gives an internal document the effect of a legal act, which a formal notice would have and a review is not. The one on an extension as of right describes something that is negotiated, never a entitlement: an insurer assesses a future exposure, and may decline it. The answer promising recharacterization as a latent defect inverts that notion, which characterizes what was not detectable AT ACCEPTANCE and not what has yet to manifest today.
