Title page


‘Measurement using the New Rules of Measurement’ is intended to provide some guidance on how to measure quantities in accordance with NRM 2 using comprehensive and detailed examples of most of the sections in the NRM 2.The text and examples have been drawn from my professional and academic practice as a chartered quantity surveyor and lecturer.

The publication by the RICS of the suite of New Rules of Measurement (NRM) provides a prescriptive approach to the measurement of quantities throughout the construction process. The second of these, NRM 2, provides new methods of measurement for work in separate trades. As is often the case with innovations, some guidance can be useful and a commentary with examples and exercises on how to use NRM 2 is therefore appropriate.

The publication of the RICS Black Book guidance notes on acceleration and damages for delay to completion provides best practice to the quantity surveying profession and could, perhaps, indicate further developments in standard methods of measurement in an area very much in need of an accurate and consistent approach.

For students and practitioners the acquisition of technical competencies is by practice. A textbook can only provide an introduction. For this reason each chapter has a step-by-step worked example that can be followed and an opportunity to practise with an exercise on each topic. Development can be monitored by using the self-assessment marking sheets that are also provided.

A work like this will contain errors and they are entirely my own responsibility. I would be grateful for your assistance if you would be kind enough to please point out these errors and I will correct them at the first opportunity. I am also aware that some of the opinions in this volume will not be shared by all. I welcome your opinions which I will carefully consider.

The author and the publisher would like to thank the following individuals and organizations for their kind permission to use the material as described below:

Barry Symonds for allowing me to use the drawings and my lecture notes.

Andrew Bateson at Cadwyn Housing Association for the use of the partition, flat roof and external works drawings.

Paul Hunt at St George Central London Ltd for the use of the services drawings and the steelwork pergola.

Balkees Noor Mohamed at the College of Estate Management for the use of the drainage drawings.

Tim Cook at Causeway Technologies Limited for the use of the CATO examples.

Palgrave for the use of the windows and door openings drawings.

Phil Young at CEREA for the use of the curtain walling drawings.

Wiley-Blackwell for the use of the sloping site, underpinning and RC frame drawings.

Many people have read and commented on parts of the manuscript and they have my sincere thanks and gratitude:

My wife, Sally, for her assistance with proof reading.

Keith Tweedy for his careful appraisal and discussions on the NRMs.

David Benge for our initial discussions on NRM 1.

Professor Allan Ashworth for his encouragement and tolerance.

David Hockley, RIBA, and Matthew Boughton who despite busy workloads prepared many of the drawings.

Ben Taylor.

David Quarmby of Glamorgan University.

Simon Pope at Causeway Technologies Limited.

The students of several institutions whom I have been privileged to teach who diligently and sometimes gleefully but always in good humour pointed out everything that they could find that was wrong or inconsistent and were kind enough to tell me what they found difficult about what they were being taught.

My publishers Wiley Blackwell for their encouragement and comments for which I am profoundly grateful.
