When You May Need a Quantity Survey or Expert Opinion 

You may require a quantity surveyor or an expert opinion report from Tyrrells when facing cost-related uncertainties or disputes in commercial property transactions, construction works, or property ownership. 

Common scenarios that necessitate a quantity surveyor or expert opinion report include: 

• Validatie builder quotes and variations to ensure costs match market rates and the agreed project scope.
• Support property purchases and leases with accurate cost forecasts and independent assessments for stronger negotiations.
• Assisting in construction dispute resolution by providing independent expert reports for NCAT, mediation, arbitration, or court proceedings.
• Preparing tax depreciation schedules for commercial assets to maximise eligible capital works and deductions. 

A good rule of thumb is to always engage early in pre-construction or due diligence phases for cost planning and feasibility to avoid resolving disputes and claims after inspections.
