# Our Data Sources

Review the transparent data sources and industry benchmarks behind the BackyardCost landscape estimation engine.

Our database is updated on a bi-monthly cycle by our team of quantity surveyors. When major material shortages or fuel surcharges affect civil excavation margins, we adjust our local state modifiers to prevent calculation drift.

This ensures that when a homeowner estimates a project in Melbourne or Sydney, the final price closely matches active bids in the local market. For more information about our calculation flow, visit how we calculate.
