- Schedule of Quantities

The schedule of quantities is a detailed document prepared by the announcing entity and attached with the tender documents. It contains a list of all the items, materials, or works required to execute the project. This schedule is meticulously prepared to ensure comprehensive detailing and clarity of specific requirements that the contractor or supplier must adhere to.

The schedule of quantities includes a detailed description of each item, the unit used (such as meter, piece, kilogram), the required quantity, and the estimated price. It is an essential tool for participants in the tender to understand the scope of work and potential costs, and it is also used as a reference to submit a price offer and determine the total cost.

One of the advantages of the schedule of quantities is that it helps the announcing entity to compare offers easily and objectively, as each offer is submitted based on the same list of requirements. It also helps to reduce confusion and ensure that all offers respond to the project's needs.

The schedule of quantities is also considered a tool for contract management after the award of the tender. During project execution, the schedule is used to monitor progress, review invoices, and verify the contractor's compliance with the agreed quantities and prices.

Preparing the schedule of quantities requires accuracy and expertise, as any deficiency or ambiguity can lead to problems during project execution. Therefore, announcing entities often rely on consultants or technical experts to prepare this schedule.
