	Best practice for the preparation of bills of quantities is set out in the New Rules of Measurement (NRM) published by the [[Royal_Institution_of_Chartered_Surveyors_RICS\|Royal Institute of Chartered Surveyors]] and replacing Standard Method of Measurement, seventh edition (SMM7). Adopting the New Rules of Measurement means that all projects are taken off in the same way and in the same order following consistent rules.

−	Increasingly, software packages are available to assist in the preparation of preparation of bills of quantities, and building information modelling systems can be used to produce bills of quantities from information already contained within the model. The process in Building Information Modelling (BIM) is often referred to as material takeoff which uses the underlying ~~parametric~~ 3D model to calculate materials takeoff for cost estimation as well as in some cases embodied carbon calculations. In this process care must be taken that digital models are a fair representation of the actual product or component, for examples metal window frames being modelled as hollow extrusions rather than solid elements, the later can impact the material take-off dramatically increasing for example the assumed aluminium used by weight.	+	Increasingly, software packages are available to assist in the preparation of preparation of bills of quantities, and building information modelling systems can be used to produce bills of quantities from information already contained within the model. The process in Building Information Modelling (BIM) is often referred to as material or quantity takeoff, which uses the underlying 3D parametric model to calculate materials takeoff for cost estimation, as well as in some cases embodied carbon calculations by adding the density factor and CO2 e per kg or volume of material.
