As the QS you have been tasked to explain to the Minister of works how gross measurement of a site earmarked for demolition with buildings on it can be measured and quantified for site clearance, using illustrations.

This demolition project required skilled labor who can follow proper safety rules and heavy machinery is used like bulldozers, wrecking ball etc.
