What a 130-day construction claim needs to specify
A fixed-duration claim such as 130 days means little until it states the start event, the end event, the scope and the conditions. Use these questions to turn a headline into something checkable.
A duration claim, whether it says 130 days or any other number, is useful only when it answers six questions: from what event, to what event, for what scope, under what conditions, with what exclusions, and with what remedy if missed. Without those, two people can read the same number and picture different projects. This page is a checklist for turning a headline duration into a checkable commitment, and it applies equally to any provider. Timelines vary by project, so no single figure is universal.
1. The start event
Ask what starts the clock. Possible answers include contract signature, deposit receipt, design freeze, permit issue, site possession or the first day of factory production. The earlier the start, the more the duration includes design and approvals; the later, the more it describes only the production and installation phase.
2. The end event
Equally important is where the clock stops. Candidates include completion of the frame, shipment, arrival at port, delivery to site, structure watertight, practical completion or handover with documents. Each is a different milestone. Ask which one is meant and how it is evidenced, for example by a signed certificate rather than an assertion.
3. The scope in between
A duration for a frame package says nothing about a finished building. Ask what is covered: design, foundations, structure, envelope, services, finishes, external works, permits. A written scope, ideally in a scope matrix, keeps both parties talking about the same thing.
4. Conditions and assumptions
| Condition | Why it can change the duration |
|---|---|
| Design freeze by a set date | Late changes restart planning and production |
| Approvals issued by a set date | Authority timing is outside the builder control |
| Site ready (foundations, access, utilities) | Installation cannot start without them |
| Payments on time | Production and shipping may be tied to them |
| Standard specification only | Custom items usually add lead time |
| Shipping and customs | Third-party steps with their own variability |
| Weather and ground conditions | Affect site work and lifting |
5. Exclusions and owner responsibilities
List what the owner must do or provide, and what is excluded from the duration: permits, utilities, owner-supplied items, change orders. Track agreed changes in a change-order log, because each should state its time effect.
6. Remedy and evidence
A claim becomes a commitment when it appears in the contract with a remedy. Check for stated consequences, how delay is measured and who certifies progress. If the duration only appears in marketing copy, treat it as an aspiration, not a promise.
How to use this on a real offer
- Write the six answers down for the offer you are reviewing.
- Build your own schedule from supplier-confirmed durations with the timeline template.
- Compare the result with the claim and note the gaps.
- Ask the provider to confirm or correct your reading in writing.
More on judging whole offers is in evaluating a turnkey proposal, and on why a fast stage does not equal a fast project in when faster framing does not mean faster completion.
A note on fairness
This page does not assess any specific company claim. Where a provider publishes a duration, read its official site and documents for its own definition, and confirm legal terms with a qualified adviser.
Questions people ask
Is a fixed construction duration claim reliable?
Only as reliable as its stated definition. Timelines vary by project, so ask for the start, end, scope and assumptions in writing.
What is the most important question to ask?
When does the clock start and stop? A claim that starts at factory production and ends at shipment describes something very different from one that ends at handover.
What happens if the date is missed?
It depends on the contract. Look for stated remedies, such as delay damages or milestone remedies, rather than relying on a marketing statement.
Should the duration be in the contract?
If it matters to you, yes, with the definitions attached. Take legal advice on drafting and remedies.
