Whether it\u2019s a residential building, highway infrastructure or a multi storey commercial complex, accurate estimation ensures the project is financially viable and sustainable. This is where <strong>quantity surveying<\/strong> comes in.<\/p>\n<p>A <strong>Quantity Surveyor (QS)<\/strong> estimates project costs, prepares budgets and manages expenditure throughout the construction lifecycle.
