ConsensusDocs 200 Weather Delays, Explained
ConsensusDocs 200 is the industry-coalition alternative to AIA A201, and its weather language is close enough to lull you and different enough to hurt you. The substance is familiar. The clock is a week shorter.
The entitlement: §6.3.1
Section 6.3.1 provides that a contractor delayed in the commencement or progress of the Work by any cause beyond its control is entitled to an equitable extension of the Contract Time. Among the listed examples of such causes: adverse weather conditions not reasonably anticipated.
Two words in that phrase carry the weight.
- "Adverse" — not severe, not unusual, not abnormal. The threshold vocabulary is softer than the FAR's "unusually severe." Do not over-read that; the qualifier that follows does the limiting.
- "Not reasonably anticipated" — this is an expectation test, not a severity test. The question is not whether the storm was impressive. It is whether a competent contractor bidding this site, in this season, should have planned around it.
The consequence is the same as under every other form: the clause is meaningless without a baseline. "Reasonably anticipated" is a comparison, and you supply the thing being compared against. See unusually severe weather: what actually counts for how that number gets built.
The two-stage clock: §8.4
This is the provision most likely to cost you a legitimate claim, because it is shorter than A201's and split in two:
| Stage | Deadline | What is due |
|---|---|---|
| Claim | 14 days from the event | The claim itself — notice that you are seeking time and/or cost relief |
| Documentation | 21 days after that | The supporting analysis and evidence |
Section 6.3.3 additionally requires written notice of a delay to the owner, and obliges both parties to mitigate its effect.
The split is a gift if you use it as intended. You are not required to have your weather analysis finished in fourteen days — you are required to have claimed in fourteen days. Subs routinely miss the first deadline while assembling material that was never due until the second.
Practical rule: file the claim on the rain event, not on the finished exhibit. Fourteen days from the first unworkable day, in writing, identifying the dates and affected activities. Then use the following three weeks for the baseline comparison and daily-log package.
The mutual duty to mitigate
The obligation in §6.3.3 running to both parties is a real difference from the AIA approach, and it is worth remembering when an owner pushes back. If the owner refused a reasonable resequencing, declined access that would have let weather-independent work proceed, or sat on a decision during the delay period, that is relevant to the mitigation question rather than merely unhelpful.
It cuts at you too. Document what you did do — crews redeployed to weather-independent scope, dewatering, protection measures. A delay record that shows a site simply stopped is weaker than one showing a contractor working the problem.
ConsensusDocs 200 vs AIA A201 on weather
| ConsensusDocs 200 | AIA A201-2017 | |
|---|---|---|
| Test | Adverse weather not reasonably anticipated (§6.3.1) | Abnormal for the period, not reasonably anticipatable, adverse schedule effect (§15.1.6.2) |
| Remedy | Equitable extension of Contract Time | Extension of Contract Time (§8.3) |
| Money | Generally no | Generally no |
| Claim deadline | 14 days, +21 to document (§8.4) | 21 days (§15.1.3) |
| Mitigation | Mutual duty (§6.3.3) | Primarily on the claimant |
The headline: the tests are near-identical and the deadlines are not. A sub who runs A201 habits on a ConsensusDocs job is a week late before starting. If you work under both forms, the safe operating rule is to treat every weather event as if the 14-day clock applies.
What proves the claim
Same evidence stack regardless of which form you are under:
- The baseline — what should reasonably have been anticipated at this location in this month, from the nearest official station over a 10-year window.
- The actuals — measured precipitation for the period, from that same station.
- The unworkable days — including the drying tail after the rain stops, which is where earthwork claims are won and where documentation is usually thinnest. See jobsite soil drying time.
- The schedule impact — the affected activities and their position on the critical path.
- Timely notice — inside 14 days, in writing.
