Tax Depreciation Schedule
We prepare ATO-compliant tax depreciation schedules for investment properties, calculating capital works and plant equipment allowances. Our services include site inspections, cost estimation for renovations, and applying Prime Cost/Diminishing Value methods to maximise tax returns while ensuring regulatory compliance.
Cost Planning
Our cost planning services monitor project budgets from feasibility through tender stages, providing accurate estimates for resources, materials, and labour. We use digital measurement tools to track expenditures against project timelines and deliver regular cost reporting to maintain financial control.
Bill of Quantities
We create detailed bills of quantities following Standard Method of Measurement guidelines. These documents form critical contract components by quantifying all construction works required, ensuring accurate tendering and transparent project costing for builders and contractors.
Project Scheduling
Our scheduling support maps all project activities with start/finish dates, milestones, durations, and dependencies. This comprehensive planning ensures coordinated delivery across complex construction projects, helping stakeholders track progress and manage resource allocation effectively.
Insurance Valuations
We calculate accurate insurance replacement costs covering building reconstruction, debris removal, and professional fees. These valuations ensure adequate coverage for natural disaster scenarios while maintaining compliance with insurer requirements and industry standards.
