CIRCA Build

A new standard in building replacement modelling for the insurance industry, CIRCA Build is accurate, transparent, and built for ease.

Overview

CIRCA Build is a purpose-built building replacement cost calculation model that blends trusted construction cost data with rich property characteristics to generate flexible, address-level rebuild scenarios. Delivered via API, it’s designed for fast integration, informed decision-making, and improved customer experience. 

How the Model Works

  • WT Australia Costings: reliable, regularly updated construction cost data grounded in quantity surveying expertise.
  • CIRCA Attributes: a complete property attribute dataset where each data point is accompanied by a confidence score.
  • CIRCA Algorithm: our proprietary engine that combines these inputs to produce six defensible rebuild scenarios per address. 


This integrated model brings together high-quality data, clear methodology, and proprietary intelligence to deliver outcomes others can’t easily replicate. 

Key Benefits 

  • Address underinsurance with multiple tailored rebuild outputs (rather than one generic estimate).
  • Enhance trust and regulatory compliance through transparency and attribute-level confidence scoring.
  • Deploy quickly via a fully API-driven solution—available within weeks, not months.
  • Improve quoting and conversion by simplifying decision-making with comprehensive yet clear estimates.

Model Highlights 

  • Six rebuild scenarios per address, covering different property types and construction standards.
  • Confidence-scored data ensures clarity at every attribute level.
  • Transparent methodology supports defensible underwriting and auditing.
  • API-first architecture for seamless integration into existing workflows.
  • Built to scale—works standalone or as part of combined building and contents solutions.
