CausewayOne Estimating
Buckinghamshire, United Kingdom
What it is
CausewayOne Estimating is web-based software for contractors and subcontractors managing bids and tenders. Estimators can create Bills of Quantities, assign resources and trades, and reuse standard pricing or earlier estimates. CAD/BIM Measure supports takeoffs from BIM, DWG, and PDF drawings, measuring areas, lengths, volumes, and curved or pitched surfaces. Drawing comparison, snapping, and custom scaling tools support on-screen measurement. The platform compares subcontractor bids and automatically flags missing or deviant rates. Subcontractors can access tender packages and submit prices, while estimators can issue revised drawings and specifications as addendums. Central document storage includes version control and audit trails, with drawings and documents assigned to trade packages. Causeway describes the system as multi-user, cloud-native, and accessible from any device with an internet connection. Single Sign-On is available. The product is paid with pricing on request. Causeway offers a support portal, knowledge base, training courses, and access to its support team.
