Celestia is the single source of truth for civil engineering projects — payment certificates, variations, claims, site records and the full audit trail, from bill of quantities to final account. A tamper-evident ledger proves every decision.

Commercial control, site and technical records, and governance — built for the way civil engineering contracts actually run.
Bill of quantities, payment certificates, CPA escalation, variations, claims and cashflow forecasting — reconciled from tender to final account.
Site instructions, RFIs, NCRs, daily diaries, programme tracking and a visual progress tracker — the field record that backs every claim.
Role-based access, document sign-off and a tamper-evident, hash-chained audit ledger — so every figure and decision can be proven later.
No more spreadsheets scattered across drives. Every instrument is linked — a variation knows its instruction, a certificate knows its claim.
Load the BoQ, contract type (GCC/FIDIC), parties and programme.
Capture diaries, instructions, RFIs and NCRs as work happens.
Certify progress, escalate with CPA, assess variations and claims.
Sign-off and a hash-chained ledger keep an unbroken evidence trail.
Reconcile to a defensible final account, fully auditable.
Charge is per active project — about two billed hours a week. Unlimited engineers, site staff and client logins are included, so getting the client into the dashboard never costs you more. ZAR, excl. VAT.
