Quantity surveyors are expected to be able to measure the perimeters of buildings as part of their routine practice. Building perimeter measurements are very useful in finding out the overall lengths of foundations, external walls, external wall finishes and associated items. One of the earliest difficulties faced by quantity surveying and construction management students, is mastering the technique of calculating perimeters of awkwardly shaped building plans. The student is typically required to calculate a perimeter and adjust this to derive the centrelines of various elements in the associated construction details. In this paper, the author aims to explain these processes, comments on various worked examples from the literature, and provides a number of worked examples from past Department of Education Builders’ Quantities Intermediate Stage examinations to demonstrate best practice in this area. The paper is addressed to students taking introductory modules in measurement and quantity surveying studies.
