Standard methods of measurement in infrastructure

Unlike surveyors in the building sector, those in civil engineering are often faced with a number of different methods to measure or quantify works. Standard details and specifications vary from rail, to roads, to utilities, etc. The underlying concern of all these methods, however, is to ensure accuracy and consistency.

This section explores the standard methods of measurement that may be used in infrastructure, including RICS' NRM 2, CESMM4 and others. Although this is the particular focus, attention is also paid to measurement conventions. Today, while the majority of bills of quantities are produced using proprietary software packages, a thorough knowledge of measurement conventions is essential in order to understand potential problems. A measurement example is also provided.
