What is a QS Report or Quantity Surveyors Report?
A Quantity Surveyor’s (QS) report is a detailed document that evaluates the financial aspects of a construction project or dispute. In litigation, a judge may request a QS report to determine the financial losses incurred. This report provides an objective assessment of costs, aiding in fair dispute resolution.
 
The report typically includes an analysis of actual and forecasted costs, and identifies discrepancies between estimated and actual expenses. It also assesses the financial impact of delays, disruptions, or changes to the project, offering a clear understanding of the project’s financial state for legal decisions.
 
In some cases, a quantum meruit report is needed to determine the value of work done without an agreed contract price, ensuring fair compensation. Additionally, a quantum expert witness report, prepared by a quantity surveyor acting as an expert witness, provides an unbiased financial assessment to support court claims.
 
In summary, QS reports, including quantum meruit and expert witness reports, are essential in litigation for evaluating financial impacts and losses in construction projects. These reports offer accurate assessments, aiding in dispute resolution and achieving fair outcomes.
