What CausewayOne Estimating is

CausewayOne Estimating is a cloud-based estimating platform for contractors and subcontractors managing bids and tenders. Estimators can create Bills of Quantities, allocate resources and trades, and reuse standard pricing or previous estimates. Its CAD/BIM Measure tools support takeoffs from BIM, DWG, and PDF drawings, measuring areas, lengths, volumes, and curved or pitched surfaces. Drawing comparison, snapping, and custom scaling tools are also available. For subcontractor bids, the system compares rates and automatically flags missing or unusual values. Subcontractors can access tender packages and submit pricing through the platform; estimators can share revised drawings and specifications as addendums. Documents are stored centrally with version control and audit trails, and drawings and documents can be allocated to trade packages. Causeway describes the product as multi-user and accessible from anywhere with an internet connection, for collaboration across devices. Single Sign-On support is available. Causeway offers a support portal, knowledge base, training courses, and access to its support team. The product page invites prospective customers to book a demonstration or contact Causeway, but does not state a price. Causeway describes the product for small contractors and growing businesses as well as other contractors and subcontractors.
