ÄTA-granskning: fixed-price assessment, what you get and when, is fixed before the file is opened. The service reviews variation order claims, ÄTA short for ändring, tillägg, avgående (change, addition and deduction), against the underlying contract, checks notice compliance and valuation basis, and delivers a written assessment within a stated number of working days. Scope, exclusions and turnaround are agreed at intake, not renegotiated once the review has started.
Who this concerns
Contractors, subcontractors, project owners and in-house counsel facing an ÄTA claim on a Swedish construction contract fall inside this scope. It applies whether the claim has arrived as an invoice, a formal notice under the contract, or a draft demand ahead of adjudication. The product is built for a party that needs a written, structured opinion on the strength of a claim before it responds, not for a party whose dispute is already being run by litigation counsel with a live case strategy.
Read this if you are the party that will pay, or the party that submitted the ÄTA and expects to be paid, and the amount at stake is large enough that a wrong response carries a real cost. The assessment does not replace project management on site; it replaces guessing about where a written claim actually stands. For the wider set of drafting and dispute tools around construction and supply contracts, see the contracts and transactions hub.
What the law says
Sweden has no dedicated statute for construction variation orders. Claims of this kind are governed first by the terms the parties actually signed, read against the general principles of Swedish contract law as it currently stands. Where the contract incorporates a standard form, that form's own mechanism for notice, valuation and time extension controls the outcome. Where it does not, the party asserting the claim carries the burden of showing that the change was instructed, or was necessary, and that the price or time consequence follows from whatever valuation method the parties actually agreed.
Silence in the contract does not default automatically in either party's favour. It is filled by conduct, correspondence and prior dealing between the parties, which is exactly the material this assessment reviews. Where the client, the main contractor or the ultimate parent sits outside Sweden, the governing law clause and the forum clause in the underlying contract, not the physical location of the works, decide which body of rules applies to the claim. That check happens before the ÄTA-granskning starts, not after the assessment is delivered.
How it works in practice
The fixed-price scope covers a document-based review, not a site investigation. Lodline reads what has already been written down and states where it stands, in writing, against a fixed structure.
What is included in the fixed-price scope
- Review of the ÄTA notice or notices against the contract's own notice and valuation clauses
- An assessment of whether the change falls inside or outside the originally agreed scope
- A view on the valuation basis put forward, whether unit rates, actual cost, or the contract's default valuation method
- A written risk classification for each item: strong, contestable, or weak, with the reasoning behind it
- One round of clarifying questions to the instructing party if the file received is incomplete
What is not included
- Site inspection or technical quantity surveying of the works
- Negotiation with the counterparty on the instructing party's behalf
- Drafting a response letter or a formal notice to be sent onward
- Representation in adjudication, arbitration or court proceedings
- Assessment of claims that turn on expert evidence not yet obtained by either side
Documents you need to provide
- The underlying contract, including any incorporated standard form and its appendices
- The ÄTA notice, notices or invoice in dispute
- The correspondence around the change, including any site instructions referenced
- Any response the instructing party has already sent to the counterparty
How Lodline classifies the claim
Each ÄTA item receives one of three labels. Strong means the notice complies with the contract's own requirements and the valuation basis matches what the contract allows. Contestable means the notice or the valuation has a gap that a competent counterparty is likely to exploit, but the underlying position is defensible. Weak means the notice was late, the change falls inside the original scope on the contract's own wording, or the valuation basis has no support in the contract or in prior dealing. The classification is the deliverable; it does not tell the reader what to do next, only where each item stands.
What delivery means in practice
The output is a written memorandum addressed to the instructing party, structured item by item where the claim contains more than one ÄTA. It is written to be used internally, to brief a board or a project sponsor, or to sit behind a response letter that someone else drafts. It is not a pleading and is not written for submission to a tribunal, though nothing prevents a party from using it that way once it exists.
What happens if the counterparty disputes the assessment
The assessment is Lodline's reading of the file as it stands at delivery. A counterparty is free to disagree, and often will, particularly where the classification is contestable rather than strong or weak. Disagreement at that stage does not reopen the fixed-price review; it moves the matter into negotiation or into a dispute process, which sits outside this product's scope.
Can the assessment be used in arbitration or litigation
The memorandum can be shown to a tribunal or a court if a party chooses to rely on it, but it is written as an internal assessment, not as expert evidence prepared for that purpose. Where a dispute is already running under arbitration rules, the relevant question changes to what the first procedural steps after a challenge look like, which is covered separately in the arbitration award challenge guide.
Does the fixed price change if the file is larger than expected
The scope is confirmed once the file has been reviewed for completeness at intake, not before. If additional ÄTA items surface after that point, or the correspondence turns out to run to several times the volume first indicated, that is treated as a new item requiring a separate scope, not an automatic extension of the original one.
The numbers
The fixed scope is set once Lodline has seen the file, not before it. Two variables move both the scope and the delivery time: the number of separate ÄTA items actually in dispute, and whether the contract and its correspondence already sit in English or need translation before the review can start. A single item under a standard form contract with a clear valuation mechanism behaves differently from a chain of ten items, each carrying its own valuation dispute, running against a bespoke contract with no standard mechanism incorporated at all.
Delivery time follows the same two variables and is stated in the fee proposal before either side commits to the engagement, not estimated afterwards. A party choosing this product should expect the proposal itself, not this page, to name the working days that apply to its own file.
Where it usually goes wrong
- The file arrives incomplete. The assessment is issued with caveats attached to the affected items, and the classification does not move the reader any closer to a decision.
- The claim already sits in adjudication or arbitration. The relevant work at that stage is procedural and strategic, not a document review, and this fixed-price product stops here.
- The value of the claim depends on a fact that needs a witness, such as what was actually said on site during an instruction. Document review alone cannot resolve a disputed fact.
- A party expects the assessment to be an advocacy document written to support its own position. It is written to be accurate, and a classification of weak or contestable on the instructing party's own claim is a possible, sometimes likely, outcome.
- The underlying contract has no valuation mechanism at all and the value turns on a quantum expert's opinion. That calls for a different scope of work entirely.
- The dispute is actually about a delivery failure under a supply agreement rather than a construction variation order. In that case the relevant fixed-price product is the supply agreement delivery failure assessment, not this one.
This is where the self-service part of the exercise ends and a case-specific conversation about strategy begins.
What to do next
The ÄTA-granskning tells a party where a claim stands on paper: which items are strong, which are contestable, and which are weak, and why. Whether to negotiate on the strength of that classification, escalate to adjudication, or settle a contestable item rather than fight it, is a separate question that depends on facts the document review does not reach, including the counterparty's likely conduct and the commercial cost of delay.
Where the self-review this product delivers ends and a strategy conversation begins is a short call, not another written product. Book a preliminary assessment call to confirm scope and turnaround before the file is sent.
