The RICS New Rules of Measurement provides the construction industry with a more consistent approach to the measurement and estimating of buildings. Yet despite the increased use of models, BIM systems, 3D sketches and drawings, it is still crucial to understand what to measure and how to measure it. This guide describes the process of measurement under the NRM, using plenty of diagrams, worked examples, and clear explanations of concepts and practices. Each chapter includes a detailed exercise, with solutions on a companion website. The website also includes PowerPoint slides, demonstrating the topics discussed.
