1. Preamble: The preamble in a bill of quantities is an introductory section that provides important information about the project, such as the name of the project, the location, the client, the architect, the contractor, and the date of the document. It may also include a brief description of the work to be carried out, the scope of the project, and any special conditions or requirements.
2. Contingency sum: A contingency sum in a bill of quantities is an amount of money set aside to cover unforeseen or unexpected costs that may arise during the course of the project. It is typically expressed as a percentage of the total project cost and is included to provide a buffer against potential cost overruns.
3. Prime cost sum: A prime cost sum in a bill of quantities is a specific amount of money allocated for the purchase of materials, products, or services that have not yet been selected or specified. It is used to estimate the cost of items that are subject to change or negotiation, such as fixtures, fittings, or finishes. The prime cost sum is typically based on the best available information at the time of preparing the bill of quantities and may be adjusted as the project progresses.
4. Query sheet: A query sheet in a bill of quantities is a document used to record and address any questions, clarifications, or discrepancies that arise during the tendering process. Contractors or suppliers may submit queries to the client or the project team regarding the bill of quantities, and their responses are typically documented on the query sheet to ensure that all parties have a clear understanding of the scope of work and the pricing requirements.
