The Problem With Most Site Diaries
A traditional construction site diary often lives in places that fall apart when you need evidence. Sound familiar?
A paper construction site diary book that gets lost, damaged, or never leaves site
Spreadsheets and shared drives that no one fills in consistently or on time
Text messages and photos buried in group chats you can never find again
Someone's memory — end-of-day write-ups with critical details missing
No audit trail when delays are questioned or quality is disputed
Hours wasted compiling a daily diary construction site managers shouldn't have to chase
