The measurement of building elements is a core subject for all  quantity surveying students. 
Willis's Elements of Quantity  Surveying explains from first principles the measurement  process of all the key building elements, and contains many  illustrative examples. The 11th edition maintains that approach.   
The book opens with an over-view of the need for measurement and  the differing rules governing the measurement at different stages  of the design or project cycle. The main focus of the book remains  the detailed measurement of building elements using the rules from  SMM7, but it recognises the publication of the New Rules of  Measurement: Order of Cost Estimating and Elemental Cost  Planning, by the Royal Institution of Chartered Surveyors  (RICS) and covers its relationship with the rules for measurement  of building works when producing bills of quantities for tendering  purposes. The book concludes with guidance on how to use the data  collected during the measurement process to create the tender  documents.
  This classic text, first published in 1935 under the authorship  of Arthur J. Willis, quickly established itself as a landmark in  building textbooks and was published in subsequent editions under  the authorship of two further generations of the Willis family. In  this 11th edition the hallmarks of the first edition –  clarity and practicality – have been maintained while  ensuring the book is fully up to date, providing the student of  quantity surveying with a first class introduction to the  subject.
