Tax Depreciation Schedules
BDSA Quantity Surveyors prepares ATO-compliant tax depreciation schedules for residential and commercial properties. Our reports identify all allowable asset depreciation and capital works deductions to maximise investor tax returns. Services include detailed property inspections, asset life calculations, and 10-40 year deduction forecasts tailored to construction dates and ownership structures.
Construction Cost Estimates
We deliver accurate construction cost estimates for architects, developers, and builders. Our services include feasibility studies, council DA submissions, and bank finance reports with detailed cost breakdowns for materials, labour, and compliance requirements across residential and commercial projects.
Expert Witness Reports
Our expert witness services address construction disputes through detailed cost analysis and litigation support. We prepare tribunal/court reports on contract breaches, defect claims, and project audits, leveraging 30+ years of industry experience to provide clear, defensible documentation.
Sinking Fund Forecasts
We create sinking fund forecasts for property strata schemes to ensure adequate reserves for future maintenance. Our reports analyse building lifecycles, repair timelines, and levy distributions to prevent special contributions while maintaining asset value.

BDSA provides council DA cost estimates including Section 94 contributions and EDC reports. These detailed analyses help developers meet regulatory requirements by forecasting infrastructure costs, compliance expenditures, and project viability metrics for approval processes.
