Workforce
£9/mo · included from SoloA site diary that proves what the weather did
Three weeks of rain in February, and come the extension-of-time claim nobody can prove which days you lost. One dated entry per job per day fixes that: weather and temperature, who and what was on site, work carried out, delays, visitors, notes. The weather data is stored against the entry rather than looked up afterwards. Included from Solo up.

What the Site Diary module does
- One dated entry per job per day, with the author recorded.
- Captures weather and temperature, and stores the underlying weather data against the entry.
- Records workers on site and plant on site.
- Work carried out, delays, visitors and notes are separate fields, so you can pull the delays out as a set instead of reading eight months of paragraphs.
- Site photos can be linked to a diary entry, so the evidence sits with the day it describes.
- Diary entries can be exposed to the client through the Client Portal.
Site Diary: how it works
Why does a site diary matter commercially?
Because extension-of-time and loss-and-expense claims get decided on contemporaneous records. A diary written on the day, naming the weather, the labour on site and what held you up, is evidence. The same thing written from memory in six months is an argument you’ll probably lose. Delays sit in their own field so you can pull the whole set out at once.
Is the weather recorded automatically?
The entry carries a weather description and a temperature, plus the underlying weather data record. So the conditions on the 14th are pinned to the 14th, rather than looked up two years later from a public source that may not say the same thing any more.
Can the client see the site diary?
Only if you give them a portal login. The Client Portal module shows recent diary entries next to progress, photos and documents. Without it, the diary stays internal.

Questions
Site Diary: frequently asked
Which plan includes the site diary?
It’s included from Solo up. The weather, the workforce, the plant, the visitors and the delays all come with it.
Can I fill the diary in from site with no signal?
Yes. Estimark installs as a progressive web app and has an offline field mode, so the entry is written on the phone and sent when there is a signal. Native apps for iPhone and Android are on the way, and neither is on a store yet.
Can photos be attached to a diary entry?
Yes. A site photo can be linked to a diary entry, and to a defect, and to an RFI. One upload, three records.
