Contracts 'with quantities' are priced on the basis of drawings and firm bills of quantities. 'Without quantities' means a contract priced on the basis of drawings and usually another document, such as a specification or work schedules.
JCT contracts are known for being highly prescriptive. Although the standardised format may provide clarity, it can also limit flexibility. Each JCT contract is structured around a specific set of terms and clauses, which may not suit every project's unique needs or challenges.
The employer must provide drawings together with a description of works, and either a specification or work schedules at tender stage. The project is generally not complex enough to require bills of quantities.
The term 'without quantities' refers to a construction contract or tender documents that do not include specific measured quantities of the items of work identified by the drawings and specifications. It can be used on projects where it is not possible to prepare a bill of quantities (BOQ) at the time of tendering.
BOQ vs BOM While a bill of quantities (BOQ) includes an itemized list of all project costs — including materials and labor hours — a bill of materials (BOM) only includes materials. Some general contractors include a BOM in the bid packages for subcontractors, on large and small projects alike.
