Our team of chartered quantity surveyors combines technical construction knowledge with comprehensive tax legislation expertise to deliver reports that are accurate, compliant, and results-driven.
Whether you require a detailed tax depreciation schedule for your investment property, comprehensive cost planning for a major development, or independent expert witness services for dispute resolution, Costin Quantity Surveyors brings the qualifications, experience, and local market knowledge to support your success.
At Costin Quantity Surveyors, we provide an integrated suite of professional services designed to support every phase of property ownership and construction project delivery

We specialise in preparing comprehensive tax depreciation schedules that maximise deductions for residential, commercial, and business property owners across Melbourne and Australia. Our schedules capture both capital works deductions (Division 43) and plant and equipment depreciation (Division 40), ensuring you claim every dollar you're entitled to under Australian taxation law.

From initial feasibility studies through to final project completion, our quantity surveying services provide the cost intelligence needed to deliver successful construction outcomes. We prepare detailed cost estimates, manage project budgets, assess progress claims, and provide ongoing cost advice throughout the construction phase.

Our cost consulting services help architects, developers, builders, and property owners make informed decisions at every project stage. We develop accurate cost plans from preliminary concepts through to tender documentation, ensuring your Melbourne construction project remains financially viable and within approved budgets.

We provide comprehensive contract administration support, including progress claim assessments, variation analysis, cost reporting, and financial forecasting. Our services help project managers maintain control over construction costs while ensuring contractors are paid fairly for completed work.

Representing major Australian financial institutions, we prepare initial bank reports and progressive drawdown valuations for development projects across Melbourne. Our independent assessments provide lenders with confidence in project progress and financial management.

When construction disagreements arise, our independent expert witness services provide clear, unbiased cost assessments for VCAT hearings, court proceedings, mediation, and insurance claims. We prepare defect valuations, cost to complete reports, and expert evidence that helps resolve disputes efficiently.
Every report we prepare adheres strictly to Australian Taxation Office guidelines, Australian Institute of Quantity Surveyors standards, and financial institution requirements. Our commitment to compliance means you can rely on our work with complete confidence, whether you're claiming tax deductions or securing project finance.
Our team stays current with legislative changes, ATO rulings, and industry best practices to ensure your reports remain compliant and defensible in any review or audit situation.
Precision is fundamental to quantity surveying. Our chartered quantity surveyors use proven methodologies, current market data, and detailed site analysis to ensure every calculation reflects true values and costs.

For cost consulting, it means estimates you can confidently present to lenders, boards, or clients knowing they reflect realistic construction costs in Melbourne's current market.
