A bill of quantities (BQ) provides a detailed breakdown of materials, labour and costs needed to complete a building project for the contractors and property owner. It makes budget planning easier as it presents a clear breakdown of different work items. As an illustration, if developing a house, it can contain the approximated product amounts of bricks, cement, steel, flooring materials, and various other materials. This information also aids to compare the quotations of different contractors and also determine bill of quantities . Creating this document prior to work will decrease the confusion and enhance cost management. Can a breakdown of costs be useful in avoiding any unforeseen costs when building a home?
