Résumé :
Willis's Elements of Quantity Surveying

A fully-updated new edition of the classic quantity surveyor's guide

Quantity Surveying (QS) involves the practice and management of costs related to building and civil engineering projects. Built on the fundamental skill of measuring building quantities, QS practitioners offer a range of services including cost assessments for life cycles, reducing carbon emissions, and more. For almost ninety years, Willis's Elements of Quantity Surveying has been the indispensable introduction to the theory and practice of quantity surveying. Now updated to reflect the latest standards and practices, it promises to train a new generation of skilled contributors to the building and engineering trades.

Readers of the fourteenth edition of Willis's Elements of Quantity Surveying will also find:

• New chapter on measuring electrical works
• Companion website with videos and worked-through examples for instructors
• Updates reflecting the 2021 edition of the Royal Institution of Chartered Surveyors' New Rules of Measurement 2

Willis's Elements of Quantity Surveying is ideal for all undergraduate students in quantity surveying and related construction disciplines....
