A common example of this is when measuring drain pipes, for which the estimator may determine a cost based on the full length of the pipe measured along its centre-line, and then assess an ‘extra over’ cost for the additional cost necessary to pay for fittings such as bends and junctions.

‘Extra over’ (EO) is a term that is often used when taking off for a bill of quantities (BoQ). Taking off is the process of identifying elements of construction works that can be measured and priced. It is a necessary process for producing a BoQ.

When taking off for a BoQ, the term ‘extra over’ can be used for certain items that to a certain extent have already been measured and are not to be priced at the full value of all their labour and materials. A common example of this is when measuring drain pipes. Fittings such as bends and junctions are measured as EO items since the estimator measures the full length of the pipe (including the fittings) and assesses the cost for the fittings as ‘extra over’ that of the pipe cost.

NRM2 stipulates that some types of excavation should be measured as EO, including excavating below ground water level, next to existing services, breaking out rock and reinforced concrete, and so on.

EO items should be listed directly beneath the main item over which they are measured, as this simplifies the BoQ for the contractor when they have to read and interpret it. If the EO item cannot be listed immediately beneath, reference should be given in its description to the main item it relates to.
