1. Elemental bill of quantities: This type of bill of quantities breaks down the project into different elements or components, such as foundations, walls, roofs, etc. It provides a detailed breakdown of the quantities and costs associated with each element.
2. Approximate bill of quantities: This type of bill of quantities provides an approximate estimate of the quantities and costs involved in a project. It is often used in the early stages of a project when detailed design information is not yet available.
3. Trade bill of quantities: This type of bill of quantities breaks down the project by trade, such as plumbing, electrical, carpentry, etc. It provides a detailed breakdown of the quantities and costs associated with each trade.
4. Preliminary bill of quantities: This type of bill of quantities includes the costs of preliminary items such as site preparation, temporary works, and other initial costs that are necessary to start the project.
5. Final bill of quantities: This type of bill of quantities is prepared at the end of a project and includes all the final quantities and costs associated with the completed project. It is used for final cost reconciliation and payment purposes.
