If you think that your building may be under-insured, then you need a Replacement Cost Estimate. Certainly commercial, industrial or retail properties that are built for purpose may need an expert to determine a replacement cost. Similarly, architecturally designed houses may require a Replacement Cost Estimate.
In accordance with the Strata Schemes Management Act, all Strata Schemes must have their building/s insured. And the best way to have the building adequately insured is to have a Replacement Cost Estimate prepared by an experienced Quantity Surveyor.
