A site diary that gets written the day it happened
A site diary is only evidence if it was contemporaneous. BuildLog keeps the dated record — weather, visitors, deliveries, instructions, delays and photos — on the phone that is already in your pocket, so the entry exists before the day is over.

Everything a site diary is asked to prove
Written the same day, with photos attached, and exportable years later without hunting for a notebook.
Weather with the day
Conditions recorded against the date they belong to, not reconstructed from a forecast site when the delay is already being argued.
Deliveries and visitors
Who turned up, what arrived and who was on site. The detail nobody thinks matters until somebody disputes it.
Photos on every entry
Attach photos as you write. A diary line with a picture behind it settles arguments that a line of text alone will not.
Safety observations
Record toolbox talks, incidents and near-misses in the same dated record as everything else, rather than in a separate binder.
Works with no signal
Write entries anywhere on site with no connection, and let them sync when you're back in coverage.
Export any period as a PDF
Pull a week, a month or the whole job out as a branded PDF, complete with photos, when someone asks for the record.

Construction site diaries — common questions
- What is the difference between a site diary and a daily report?
- A daily report is the formal summary issued to the client or GC — production, labor, equipment, delays. A site diary is the contemporaneous record kept for your own protection: weather, visitors, instructions, conversations, anything that might matter later. BuildLog keeps both against the same project and the same dates.
- Does the site diary work offline?
- Yes. Entries can be written with no connection at all and sync automatically once you are back on signal.
- Can I attach photos to a diary entry?
- Yes. Photos attach directly to the entry and the date, so the evidence stays with the record instead of sitting loose in a camera roll.
- Can I export the diary for a claim or an audit?
- Yes. Export any period as a branded PDF with entries and photos included, ready to hand to a lawyer, an insurer or an auditor.
- How long is the record kept?
- Entries stay with the project in the cloud, so a diary from a job that finished two years ago is still there when a dispute surfaces.
