I've been experimenting with some different architectures for a construction site diary.
If you aren't familiar with the concept, the site diary is one of the most important construction tools. You basically document everything that happens on site: who did what and how much work you got done each day. Then you use the data to feed your project control system.
It also makes incredibly powerful evidence for any construction claims
In this video I outlined a simple architecture using Airtable as the database, Claude and Claude dispatch for updating the diary, and WhatsApp for tracking project correspondence and tasks
