Historical background of quantity surveying; functions of bill of
quantities; contract documentation; processes used in quantity
surveying work; other measurement approaches; Standard
Method of Measurement of Building Works; coordinated project
information; other functions of the quantity surveyor; changes
in quantity surveying techniques.

2 Measurement Procedures 16

General rules: basic principles; tabulated rules; dimensions paper;
measurement procedures; entering dimensions; spacing of
items; waste; order of dimensions; timesing; abbreviations and
symbols; grouping of dimensions; deductions; measurement of
irregular figures; alterations to dimensions; figured dimensions;
numbering and titles of dimension sheets; order of taking off;
adjustment of openings and voids; descriptions; use of metric
symbols; extra over items; deemed to be included items; accur-
acy in dimensions; falls, crossfalls and slopes; drawn information;
use of schedules; take off lists; query sheets; preambles; prime
cost items; provisional sums; work of special types; fixing, base
and background; cO(llposite items; general definitions; services
and facilities; plant items; standard components.

3 Mensuration Applications 37

Introduction; girth of buildings: rectangular buildings; buildings of
irregular outline; measurement of areas: irregular areas; trape-
