Relationship Between Construction Technology
and Quantity Surveying..
Wikipedia defines quantity surveyor as Aprofessional person working within the
construction industry to manage and control costswithin construction projects and may involve theuse of a range of management procedures andtechnical tools to achieve this goal.

Relationship Between Construction Technology
and Quantity Surveying
Quantity Surveyors are expected to report the costeffects as soon as possible
In design stage you do estimates as soon as the
design is done. In tenders stage you analyze them as soon as
they are returned.
In construction stage you report the cost
effects of variations as soon as instructions areissued.

Why do we Need Buildings?
We build because little that we do can take place outdoors. We
need shelter from sun, wind, rain, and snow. We need dry, level
platforms for our activities. Often we need to stack these
platforms to multiply available ground space. On these
platforms, and within our shelter, we need air that is warmer or
cooler, more or less humid, than outdoors. We need less light by
day, and more light by night, than is offered by the natural
world. We need services that provide energy, communications
and water and disposal of wastes. So we gather materials and
assemble them into the constructions we call buildings to satisfy
these needs.
