Construction Project Management Software for UK Contractors

Built around the bill of quantities — the way UK work is actually measured. Valuations and applications for payment from site-measured progress, retentions tracked, and records a QS can stand behind.

Construction project management software gives UK contractors one system for BOQ-based measurement, monthly valuations and applications for payment with VAT, retention tracking, site diaries and progress from an offline-first app, and a searchable register of drawings, instructions and correspondence — audit-ready from day one.

Measurement and valuation the way a QS works

The BOQ is the backbone of UK contracting, and it's the backbone of ProjectSathi too. Load the bill, capture measured progress from site, and produce monthly valuations and applications for payment with VAT — retentions, variations and materials on site all tracked against the contract, not in a side spreadsheet.

  • BOQ-based measurement and monthly valuations
  • Applications for payment with VAT, retention tracked
  • Variations priced and carried into the contract sum

Site records that survive scrutiny

Delay and loss-and-expense positions turn on contemporaneous records. Site diaries, progress photos, weather notes, instructions and correspondence are captured as they happen, time-stamped, and searchable — with AI document intelligence to pull the thread you need when the contract administrator asks.

One platform, from a single job to a framework

Run one project or a framework's worth in a single portfolio view with per-project P&L and progress against programme. International pricing is quoted per portfolio — talk to sales and we'll demo on data shaped like your jobs.
