Construction Weather Delay Log Template
This construction weather delay log template is the full daily log. Type in the blank cells, or print the page and write on it. There is no signup and no file to download. What you type stays in this browser tab. This page does not save it. This is general information, not legal advice.
What to write in each column
- Date: the calendar date the work was affected. One row per date. If only the morning was lost, still use that date and say so in notes.
- Conditions observed: what people on the site saw, in their own words. Rain, snow, standing water, ice, wind, heat, or cold. This column is the crew's observation. It is not a weather-station printout.
- Work affected: the activity that stopped, slowed, or changed. Name the work, such as a slab pour, excavation, roofing, or a crane pick.
- Crew/equipment idle: who stood by and which machines stood by. A headcount and the equipment names are enough.
- Hours lost: how long that activity did not proceed. Use hours for that activity, not a guess about the whole project finish date.
- Notes: who decided to stop, whether a notice was sent and to whom, and where the photos from that day are filed.
Fill it the same day
- Open a row while the crew is still on site, or the same evening.
- Write the conditions someone actually saw. Keep the site gauge, if you have one, separate from later forecasts.
- Name the work that changed and the crew and equipment that were idle.
- Write the hours lost for that work, and the clock times if you have them.
- In notes, record the notice: the date it went out, who received it, and how it was sent. Attach that to the contract's own notice rule, which you read in the contract.
- Print another copy of this page when the 31 rows are full.
Example row
The row below shows the kind of note a superintendent might write. It is an example, not a record from a real project, and the cells are not part of your log.
| Date | Conditions observed | Work affected | Crew/equipment idle | Hours lost | Notes |
|---|---|---|---|---|---|
| 4 Mar 2026 | Steady rain. Site gauge read about 0.8 in. by late morning. Wind stopped crane picks. | Slab pour on grid C held. | Crew of 6 and the crane idle 7:00–11:30. | 4.5 | Superintendent stopped the pour. Notice email to the owner the same morning. Photos in the 4 Mar site folder. |

Why a log alone is not third-party proof
The log is a record of what the project wrote down. It can be detailed and still be one side's notes. A reader who has only the log cannot check three things:
- The conditions came from a named weather station, rather than from the crew.
- The same dates at that station, in earlier years, were wetter, hotter, colder, or windier than the day in question.
- The day passed a stated line, rather than simply being a day the crew lost time.
Keep the log. It is the place for the work, the idle crew, the hours, and the notice. It does not replace an outside daily record, and an outside daily record does not list which activity stopped.
Filing a delay claim?
The log above is your own notes. The separate step, when you are filing a delay claim, is a PDF of NOAA GHCN-Daily readings for the dates you choose. It uses the nearest station that qualifies and compares each day with a baseline of up to 10 prior years of those same dates. Days that pass the mean-plus-one-standard-deviation line are marked. How that line is built is on the NOAA adverse weather days for construction page. The PDF is $199, paid once, and you download it after payment. It does not decide whether a contract allows extra time. Get the weather delay report.
