In the preparation of the Agreed Rules of Measurement many people within the industry and profession have contributed. In particular we acknowledge our thanks to our predecessors who produced the Agreed Method of Measurement of Building Works Applicable to Work in Ireland (AMM) in 1952 and to our colleagues on the Standing Joint Committee for the Standard Method of Measurement who produced SMM 6 and SMM 7 as well as the Royal Institution of Chartered Surveyors who publish the Principles of Measurement (International) for Works of Construction. The first edition of ARM was published in October 1994 and Arm 2 and Arm 3 were updated to take account of users comments and industry changes. ARM 4 has been revised to meet the needs of today’s construction industry and we trust that they will be widely used and of benefit in ensuring a consistent set of rules for the measurement of building works. The Joint Committee responsible for the production of the original The Joint Committee responsible for the production of ARM up to ARM 2, was composed as follows: ARM 4 was composed as follows: Representing the Construction Industry Federation: Representing the Construction Industry Federation: Kevin Callan, Ian Hagan, Hugh McAtamney, Padraig O’Kennedy.
