Site diary software for main contractors

Main contractors carry the record-keeping burden for everyone on the job. Construction Metric builds the daily record automatically from the WhatsApp chatter your sites already produce.

Diaries decay across a portfolio

Every site keeps the diary differently, and quality drops the busier a project gets. The record is thinnest exactly when it matters most.

Sub-contractor claims arrive late and organised

When a claim lands months later, your defence depends on what your team recorded on the day, not on what anyone remembers.

Reporting eats management time

Site managers lose one to two hours a day assembling what the group chat already knows.

A main contractor lives and dies by its records. You hold the head contract, you carry the programme risk, and when anything goes wrong, upwards to the employer or downwards to the supply chain, the first question is always the same: what does the contemporaneous record say? For most main contractors the honest answer is that it depends which site you ask. One project keeps an exemplary diary. Another has three weeks of gaps because the site manager was covering two jobs. A third has everything you need, but it is spread across a group chat, a camera roll and somebody’s memory.

Construction Metric exists to make that variance disappear. It listens to the WhatsApp groups your sites already run, with consent and per project, and turns the messages, photos and voice notes into a structured daily site diary: weather, labour, plant, deliveries, progress, delays, instructions and health and safety observations, each entry timestamped and attributable. Nobody on site fills in a form. Nobody learns an app. The team keeps talking the way it already talks, and the record assembles itself in the background, every day, on every site, to the same standard.

For commercial teams the value shows up in disputes and final accounts. Delay and disruption arguments turn on dates, sequence and evidence. A diary built from messages sent at the time, with photographs attached and voice notes transcribed, is precisely the contemporaneous record adjudicators and courts give weight to. When a sub-contractor claim arrives eight months after the event, your QS searches the record and answers with facts in minutes rather than reconstructing a story over days.

For delivery directors the value is visibility. Because every site produces the same structured record, you can finally compare like with like across the portfolio: which jobs are losing days to weather, where labour is consistently short, which packages generate the most delay events. The diary stops being a compliance chore and becomes management information.

Records are filed to an ISO 19650 aligned structure in the systems you already run, so document control does not inherit a second filing job. And because capture is passive, adoption does not depend on the busiest person on the project developing a new habit. It works on the good sites and, more importantly, on the chaotic ones.

Main contractors typically see five to eight hours returned per site per week, a consistent evidence base across every live project, and a materially stronger position the next time a claim lands. One protected claim usually pays for the system many times over.

Common questions

Does it work across joint ventures and multiple companies?

Yes. Capture is configured per project group, so JV sites and sub-contractor groups can each feed the correct project record with the right access controls.

Can head office see every site?

Yes. The portal gives admin users a portfolio view across projects, while site and client access is scoped to their own jobs.
