Your estimates drive major investment decisions. Professional Indemnity insurance protects your practice when those numbers are questioned.

Numbers That Matter

Your cost estimates determine whether projects proceed. When estimates prove significantly wrong, clients who relied on your numbers may seek compensation for their losses.

Diverse Services

Modern QS practices provide cost planning, tax depreciation, insurance valuations, and more. This is different to land surveyor PI, which focuses on cadastral, boundary and setout exposures.

QUESTIONS

Frequently Asked Questions

Yes, PI insurance is essential for quantity surveyors and cost consultants. Your estimates and valuations directly affect project feasibility and investment decisions. When estimates prove significantly wrong, clients may seek compensation for their losses.
Construction costs are inherently uncertain, and scope changes are common. The challenge is distinguishing between legitimate estimating variations and professional negligence. Claims often involve complex analysis of what a competent QS would have estimated.
Yes, tax depreciation schedules are typically covered. If your schedule contains errors that affect your client's tax position, and they claim against you, your PI policy responds. This is a significant service line for many QS practices.
This depends on your project values and service types. Many QS practices carry $2-5 million. Those working on major projects or providing feasibility advice for significant investments may need higher limits.
Yes, insurance replacement valuations are covered professional services. If your valuation is inadequate and affects an insurance claim outcome, PI can respond to claims made against you.
