Quantity Surveyors control the ‘money’ for their clients in construction projects – they are experts in dealing with all financial matters related to a building project, from start to finish. They are mainly responsible for estimating the cost of a new building, calculating the materials and labour used in a building, preparing tender and other legal documents, estimate the value of work done at various stages of the contract, i.e. controlling all costs while a building is being built. They often get involved in other aspects of construction as well and in other industries such as insurance, banking, law, property development, etc. (Quantity Surveying is not the same as Land Surveying).
