Cost estimation of any construction project depends on issuing the Bill of Quantities which defines and quantifies the work items of any project to be priced. When preparing these bills, a set of guiding rules can be used to ease the preparation which is known as the Method of Measurement. Some institutions issued standard Method of Measurements such as the CESMM, NRM and POMI. Each Method of Measurement has its own characteristics and uses. The use of these standard Methods of Measurement is studied in this paper for the civil and building projects in the Middle East by preparing a questionnaire to be distributed and returned on quantity surveyors in the Middle East. The Results are analyzed and the findings are used to construct a decision support system that automates the process of selection of the suitable standard method of measurement for civil or building projects based on some project parameters. The model was validated by comparing its results with those in real life projects. A conclusion was reached the standard Methods of Measurement are used with POMI having most uses followed by CESMM unlike NRM that has least use so the model can give suitable choice for the Method of Measurement in civil projects unlike building projects since NRM is issued recently and still not used in Middle Eastern projects.
