This document discusses quantity measurement in construction projects. It describes the importance of bills of quantities in costing, tendering, and valuing payment and variations. It explains the common units used to measure length, area, volume, weight, amounts, and items. It also defines structural drawings and their purpose in showing architectural and structural details. Finally, it outlines the key elements to take off quantities for substructures, such as piling, foundations, column stumps, ground beams, and ground slabs.

BQ are prepared by the quantity
surveyors and are widely used for project costing,
tendering, as part of contract documentation
and for valuation of interim payment and variation
orders.
They are produced according to the
locally produced Standard Method of Measurement
(SMM)

7. A structural drawing, a type of technical drawing, shows
information about architectural foundations, roof, or other structural
details.
STRUCTURAL DRAWINGS (sometimes identified with the
designating letter S on their title blocks) consist of all the
drawings that describe the structural members of the building and
their relationship to each other. A set of structural drawings
includes foundation plans and details, framing plans and details,
wall sections, column and beam details, and other plans,
sections, details, and schedules necessary to describe the
structural components of the building or structure. The general
notes in the structural drawings should also include, when
applicable, roof, floor, wind, seismic, and other loads, allowable
soil pressure or pile bearing capacity, and allowable stresses of all
material used in the design.
