Quantity Surveying Services for Contractors
Maximise Variation Claims. Strengthen Progress Payments. Protect Your Bottom Line.
At HSP Advisory, we provide specialist Quantity Surveying services for
contractors across Australia, helping you recover variations, strengthen
progress claims, and protect project margins.
We understand the commercial pressures contractors face—tight margins, design
changes, and rejected claims. Our role is simple:
ensure you are paid what you are entitled to under the contract.
Contractor-Focused QS Services
Materials Take-Off & Bills of Quantities (BOQ)

Identification of scope gaps, omissions, and drawing inconsistencies

We support contractors with construction estimating and cost planning to reduce
pricing risk and improve tender outcomes.
Independent estimate reviews before submission
Cost planning for design & construct (D&C) projects
Market-aligned pricing and benchmarking
