Construction disputes and quantum: what to do in the first ten days determines how a claim is eventually priced: preserve the site record before conditions change, issue notice under the contract's own clause rather than general correspondence, and instruct someone to cost the variation while evidence is still fresh. That window decides how much of the eventual claim can later be proven.
Who this concerns
This applies to a main contractor, subcontractor or employer on a Swedish construction or engineering project the moment a dispute becomes visible: a rejected variation, a delay notice that the other side disputes, a defect allegation, or a payment withheld against a certificate. It applies whether the underlying agreement is a bespoke contract or a standard-form set of general conditions, because the ten-day window is not defined by which form was used. It is defined by what happens to physical and documentary evidence once a project keeps moving.
The people who face this most often are site managers and project engineers who are not lawyers and who make decisions about photographs, diaries and instructions long before anyone in the organisation calls it a dispute. By the time it reaches our disputes and arbitration practice, the first ten days have usually already happened, well or badly, and the file reflects which.
Commercial teams on both sides of the contract face the same clock. A party that is confident it has no exposure still needs the same discipline, because a quantum position built only after a claim is formally advanced is weaker than one built while the underlying facts were still being generated on site.
What the law says
Swedish contract law does not treat a construction dispute as a special category with its own limitation period or evidentiary rule; it applies general principles of contract and damages (skadestånd) to a factual record that either exists or does not. Under Swedish law as it currently stands, a party claiming additional cost has to establish the causal link between the event relied on and the cost incurred, and has to be able to quantify that cost by reference to something more concrete than a running total kept after the event. The strength of that link is a question of evidence, not a question the general law resolves in the claimant's favour by default.
Where the contract sets its own notice and time-bar mechanism, that mechanism generally has to be followed on its own terms rather than substituted for by an assumption that the counterparty already knew about the issue from site meetings or informal correspondence. Whether a given notice clause is a true condition precedent or a procedural requirement that can be waived depends on how the specific clause is drafted, and that is a question the contract itself answers, not a question with a single answer across all Swedish construction agreements.
Quantum, separately, is a question of proof. A Swedish court or arbitral tribunal deciding a construction quantum dispute expects the claiming party to show what was actually spent or lost, supported by contemporaneous records, rather than a reconstruction produced after the dispute crystallised. Practice in this category consistently proceeds from the position that a later reconstruction is treated with more scepticism than a record made at the time, regardless of how carefully the reconstruction is prepared.
How it works in practice
Day one: stop the record from closing itself
The most common early loss is not a missed deadline; it is a site record that keeps evolving without anyone deciding to preserve a version of it. Diaries get updated, photographs get overwritten by later ones of the same area, and instructions given verbally on site are never reduced to writing. On day one, the practical task is to take a snapshot: copy the diary as it stands, photograph the disputed area or defect before remedial work covers it, and list who was present and what was said, while it is still recent enough to be accurate rather than reconstructed.
Notice under the contract, not general correspondence
Sending an email that mentions the issue is not the same as giving notice under the contract's specific clause. If the agreement requires notice in a particular form, to a particular person, within a particular period, that form has to be used and has to be identifiable later as having been used. A notice buried inside a broader project update, with no reference to the clause it is meant to trigger, creates an argument later about whether notice was given at all. The safer approach is a standalone notice that says what it is and which provision it responds to.
Instructing someone to price the position early
Quantum built after the fact by someone with no contemporaneous involvement is weaker than a costing exercise started while the underlying documents are still being generated. Instructing a quantity surveyor or equivalent early, even informally, means the eventual position is built from source documents identified in real time rather than assembled retrospectively from whatever happens to have survived.
Preserving communications as they exist, not as they are remembered
Correspondence should be preserved in its original form and sequence, not summarised into a narrative for internal use. A summary written weeks later, however accurate its author believes it to be, is a secondary account; the underlying emails, letters and minutes are the primary record and are what any later assessment will actually rely on.
Cross-border contracts and foreign counterparties
Where the employer, main contractor or a key subcontractor sits outside Sweden, or where project assets and payment flows run through a parent company abroad, the first ten days carry extra weight. Notice provisions may specify a foreign governing law or a foreign seat for any arbitration, which changes what "giving notice correctly" actually requires. Evidence generated on a Swedish site may need to be understood by decision-makers, courts or tribunals operating under a different legal framework, which affects how it should be recorded and translated from the outset rather than after a dispute is already advanced. Where enforcement may eventually need to happen against assets held abroad, the quality of the contemporaneous record affects not just whether a claim succeeds, but whether the resulting award or judgment is something that can practically be enforced once it is obtained.
What to check in the first ten days
- Whether the contract specifies a form, recipient and time limit for notice of the specific event in question.
- Whether the site diary, photographs and instructions for the relevant period have been copied and dated before they are overwritten.
- Whether anyone with contemporaneous knowledge of the disputed work has been asked to record their account while it is fresh.
- Whether correspondence referring to the issue has been preserved in its original form, including attachments and metadata.
- Whether a quantum baseline, however provisional, has been started rather than deferred until the dispute is formally raised.
- Whether the governing law and dispute resolution clause have been checked against the counterparty's location and asset base.
Where readers get this right on their own
None of the above requires a lawyer to execute. A competent site manager or commercial manager can copy a diary, take dated photographs and send a properly referenced notice without external help. The first ten days are, deliberately, a period where the client controls the outcome more than any adviser does.
The numbers
There is no single statutory figure that makes ten days the relevant period; it is a practical benchmark reflecting how quickly a construction site record degrades once work continues, not a limitation period set by any specific provision. Whatever time limits actually apply, whether for notice, for bringing a claim, or for responding to one, come from the specific contract in front of the reader, and those figures vary between agreements. A material misstates the position if it generalises a single number across contracts that were not drafted the same way.
What can be said generally is what drives the eventual cost of resolving the dispute rather than the specific fee involved: the volume and quality of contemporaneous documentation, whether the notice mechanism was followed correctly the first time, whether expert quantum evidence has to be reconstructed rather than built from source, and whether the dispute resolution route chosen in the contract is arbitration, litigation or a tiered mechanism requiring earlier steps before either. Each of these adds or removes work later, and each is influenced by what happened, or did not happen, in the first ten days.
Where it usually goes wrong
The pattern that recurs is waiting for a formal instruction before treating the matter seriously. Site teams often assume that documentation only needs to start once someone senior confirms there is a "real" dispute, by which point the earliest and often most useful evidence has already been overwritten or forgotten. The contemporaneous record cannot be recreated later with the same evidential weight, however good the memory of the person reconstructing it.
A second recurring failure is treating general correspondence as if it satisfied a specific contractual notice requirement. Where the contract is explicit about the form notice must take, an email that mentions the issue in passing, without reference to the clause, routinely fails to count, and that failure is often only discovered once the other side raises it as a defence much later, when it is too late to cure.
This changes where the contract itself does not impose a strict notice mechanism, or where the parties have consistently dealt with similar issues informally throughout the project without objection. In those cases, a tribunal may be more willing to accept that notice was effectively given, even informally, provided the substance of the requirement, that the other side actually knew what was being claimed and why, was met. The exception does not extend to situations where the contract is explicit and the other side has never treated informal notice as sufficient before.
Quantum built entirely after the dispute is raised, from invoices and time sheets gathered retrospectively, is not automatically rejected, but it starts from a weaker evidential position than a record built contemporaneously, and that gap is difficult to close once the ten-day window has already passed.
Does a contractual limitation of liability clause cap the quantum that can ultimately be claimed in a construction dispute?
It depends entirely on how the specific clause is drafted rather than on any general rule for construction contracts. Some clauses cap direct cost only and leave delay-related loss uncapped; others cap everything but carve out deliberate breach. The limitation of liability clause guidance sets out what the drafting has to say to actually achieve a cap, which is the first thing to check before assuming a figure is fixed.
If the underlying award needs to be enforced abroad, does that change what should be preserved in the first ten days?
Yes, because an award or judgment is only useful if it can eventually be enforced against real assets, and enforcement authorities abroad will scrutinise the same contemporaneous record that a Swedish tribunal would. Where assets sit in a jurisdiction such as Ireland, the practical requirements for enforcing an arbitral award in Ireland make the quality of the underlying evidence relevant well before any award is obtained.
How do disclosure and witness practice affect the early assessment of a construction quantum claim?
Disclosure obligations and witness credibility are assessed against what was recorded at the time, not what a witness now recalls. A document created in week one carries more weight than a statement drafted in month six. How we assess prospects using disclosure explains how that record, or its absence, shapes an early view on the merits.
What to do next
The first ten days are work the client controls directly: preserving records, sending notice correctly, and starting a quantum baseline do not require an external adviser to execute. What does require one is deciding whether the notice actually satisfies the contract, whether the emerging quantum position will hold up under challenge, and whether the dispute resolution mechanism chosen at the outset still fits the scale and urgency of what has happened. Where a smaller construction claim needs a faster route than full arbitration, the expedited arbitration option is worth checking against the contract's own dispute clause before deciding how to proceed. For a review of where the position currently stands, arrange an assessment call once the first ten days of records have been gathered.
