"By the time the site manager's WhatsApp photos get filed and the spreadsheet gets updated, we're three days behind on our own site." — Verbatim from a project manager we spoke to

Site diaries done on paper, typed up in the office later

Hours of admin, information delays, and something always gets lost between site and desk.

No idea who's actually on site at any given moment

Manual sign-in sheets, WhatsApp messages, and verbal confirmations are not a system.

Finding out a plant inspection expired — after the fact

Certificates, insurances, LOLER inspections. One spreadsheet that nobody updates in time.

No more expired certificate surprises.

Construo tracks every inspection date, hire end date, and insurance expiry across your entire plant register — and tells you before anything lapses.

  • Alerts 30 days before expiry. Plenty of time to act.
  • LOLER, insurance, hire dates — all in one place per asset.
  • Track which plant is on which site and when it's due to move.
No signal, no problem

Works even when there's no internet on site.

Basements, rural sites, dense urban builds, tunnels, cuttings. Construo keeps working. Everything syncs the moment connection returns.

Your team works normally — signing workers in, completing the diary, logging incidents.
2.
Everything is saved on the device. Nothing waits for a connection.
3.
The moment signal returns, it syncs. Office teams see it within seconds. No manual uploads, no data loss.

Built to fit your business

Works the way you work.

Every construction company tracks different things. Construo adapts to you — not the other way around.

Add any extra fields you need to any part of the system. No IT department required. If your site diaries need a permit reference number, add it in 30 seconds.

Each company on Construo has their own setup. Your data, your fields, your workflow — completely separate from any other organisation on the platform.

Who uses Construo

Built for the way your sector works.

Different sectors face different challenges on site. Construo adapts to all of them.

Railway Construction

The record-keeping your possession window doesn't leave time to skip.

Railway construction runs to a different clock. Possessions are booked weeks ahead, windows are tight, and a missing competency certificate or a late incident report can cascade into programme delays and Network Rail conversations you don't want to have.

Construo gives your site agents and section engineers a fast, offline-capable way to capture everything that needs capturing — before the possession ends and the team disperses.

PTS & COSS certificate tracking
Track Personal Track Safety and Controller of Site Safety certification expiry for every worker. Alerts before anyone lapses — before they step foot in a possession.
Possession & worksite daily records
Log the possession reference, Engineering Supervisor, COSS on duty, and works carried out — signed off before the possession is handed back.
On-Track Plant (OTP) register
Track OTP alongside road-going plant, with machine controller records, LOLER certificates, and possession allocation history in one place.
Works offline in any possession
Underground stations, tunnels, rural cuttings — wherever signal is absent, Construo keeps running. Syncs the moment connection returns.
"Getting PTS certificates chased and filed before possession start used to fall to whoever remembered. Now it's in the system with an alert. One less thing to chase."
