Site Diary
A site diary is a daily record of activities, conditions, and events on a construction site, serving as a contemporaneous log for project management and dispute resolution.
A site diary is the daily record of what happened on site. Weather conditions, workforce numbers, equipment on site, work completed, safety observations, visitors, delays — it all goes in the diary. It sounds mundane, but a well-kept site diary is one of the most valuable documents on a construction project.
Why? Because construction disputes are often settled based on contemporaneous records. If a contractor claims two weeks of rain delays six months after the fact, the site diary is what proves or disproves it. If there's an accident and WorkSafe investigates, the diary shows what safety measures were in place. If a subcontractor claims they were on site for five days but you only saw them for three, the diary is your evidence.
The problem with traditional site diaries is that they're often handwritten, inconsistent, or simply not done. A superintendent might fill in Monday's diary on Thursday from memory, which defeats the purpose of a contemporaneous record. And paper diaries are impossible to search, aggregate, or report on.
Good project managers treat the site diary as non-negotiable daily practice — like brushing your teeth. Five minutes at the end of each day to record conditions, progress, and any issues. That discipline pays for itself the first time you need to defend a claim or explain a delay.
How UpScale Handles This
UpScale's site diary is purpose-built for daily recording. Each entry captures weather, work summary, safety notes, delays, and photos. You can log labour by trade, equipment usage, and visitor sign-ins — all structured and searchable. When a dispute arises, you can pull up any day's record in seconds instead of flipping through a paper notebook.

Extension of Time (EOT)
An extension of time is a formal claim by a contractor for additional time to complete the works due to qualifying causes of delay beyond their control.
Practical Completion
Practical completion is the contractual milestone when a building is sufficiently complete for its intended purpose, triggering key obligations like defects liability and final payment.
Defects Liability Period
The defects liability period (DLP) is a contractually defined period after practical completion during which the contractor is obligated to return and rectify any defects that become apparent.
