Quantity is a measurement of a physical entity in units that depend on the nature of that entity. Therefore, quantity indicates how much of something there exists, existed or will exist.

In construction, ‘measured quantities’ form part of a bill of quantities and indicate how much of something will be required to construct a building or part of a building.

Usually prepared by a quantity surveyor (QS), the BoQ provides project-specific, measured quantities of the items of work identified by the drawings and specifications (which form part of the tender documentation). For example, in a traditional building, the BoQ will contain measured quantities for each item that goes to make up the final construction e.g bricks, doors, ironmongery, floor tiles, roof slates, etc. This means that potential tenderers know exactly how much of a given quantity will be required for the work and so what they must price for. It gives a level playing field as all tenderers are pricing for the same measured quantities which allows the client to make easy comparisons between the bids.

Measured quantities may be expressed in number (e.g door handles), length (e.g handrails, kerbs), area (e.g floor tiles, plaster), volume (e.g concrete) or weight (e.g gravel).

When prices have been entered by a tenderer beside each measured quantity in a BoQ, it constitutes the tenderer’s offer and can be reviewed by the client or the client’s cost consultant (normally a quantity surveyor).

Not having measured quantities would require the various tenderers on a project to ‘take off’ the quantities themselves. With numerous tenderers with possibly different methodologies, as well as human error creeping in, the quantities taken off would vary thus making the client’s job in comparing the tenders that much harder. Measured quantities establish a level playing field and bring objectivity and fairness into the tendering process.
