Anyone can keep a weather log. A delay claim, a federal schedule review and an inspector each ask for something more specific, and they say what in public documents. AllClear builds its record to those documents.
Each site is baselined against NOAA's 30-year monthly normals: how many adverse-weather days the month should have had, and how many it did.
UFGS 01 32 17.00 20 sets this baseline.
Every lost day names the activity it stopped, by your own schedule's activity ID and name, with the cause as it was recorded at the time.
AIA A201-2017 §15.1.6.2 asks for an “adverse effect on the scheduled construction”.
A lost day means the crew could not work at least half of it on that activity. You can set a different test per contract. A no-go alone never counts, and a go alone proves nothing: a person confirms what happened.
UFGS 01 32 17.00 20: at least 50 percent of the day on the impacted activity.
Each lost day rests on the superintendent's own answer in that day's log: whether the work stopped, and when it could restart. The specification also asks for a narrative of cause. AllClear does not write one. It supplies the recorded calls and the superintendent's own words to whoever does.

Thunder heard, Josh Rivera
“Wind never came back under 25. Pick moved to Monday.”
8.0 of 10 scheduled hours, 80 percent. Claim notice under the contract is due by 10 Oct 2026, 21 days after the event.
Rules are versioned, with a named approver and the dates each version was in force. A decision copies the limits at the moment it is made, so editing a rule in October cannot change what September's record says.
An override is allowed. It carries a name and a reason, and it sits in the record beside the call it overrode.
Exterior hoist runs
Sustained wind is above the warning limit.
Wind is 17 mph against a 15 mph warning limit in Crane Operations, version 3.
“Continuing hoist runs with a spotter at the landing. Loads under half capacity until wind drops below 15.”
OSHA's heat emphasis program took effect on April 10, 2026. It sends inspectors out on any day the National Weather Service issues a heat warning or advisory. Near the top of their question list is how the employer monitored ambient temperature at the worksite, and they note any heat alerts from the days before.
AllClear answers from what it already kept: a reading every 30 minutes, the alerts in effect that day and the days before, the rule your company had adopted, and who was told.
There is no federal heat standard today, and AllClear does not claim to make anyone compliant with anything. It shows what you monitored and what you did.
The certified weather record is NOAA's. Certified copies come from NCEI, and most orders start at $191. What NOAA cannot show is what your company knew, when, what its own rule said that day, who was told and who saw it. AllClear keeps that, and tags every reading with its station or grid point, its provider, and whether it was forecast or observed, so the two records can be laid side by side.
Bring one site and the rules you already work to. In twenty minutes you will see its call, the text your crew would get, and the record it leaves behind.
