Course Aims & Objectives

At the completion of this course, the student will:

Able to describe technical information related to the building.

Explain the availability, properties, selection, use and maintenance ofcommon building components and the application.

Able describe alternative substructures of the construction in a building

environment.

Demonstrate a knowledge of construction

Describe appropriate construction methods for internal elementsincluding f loors, partitions, ceilings, stairs, windows and doors.

Describe internal and external surface finishes appropriate to the use of

the space and the needs of the user. Identify alternative service

Advanced technologies and new methods

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.

and Quantity Surveying

The traditional role of a quantity surveyor includes

Estimation

Tender Documents

Tender Analysis and Negotiation

Interim Payment Valuations

Financial Statements

Assessment of Variations and Claims Final Account

Recent expansion of Quantity Surveyors role hasincorporated new services as follows

Value Engineering Risk Management

Life Cycle Costing

Dispute Resolution

Expert Witness

Project Management

So Quantity Surveyor needs technical knowledgeand technical updates critically

UNIVOTEC


13/66



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.

and Quantity Surveying.

Note the term As soon as possible.

So again Quantity Surveyor needs technical

knowledge and updates critically

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.

Substructure

Substructure ~ can be defined as all structure below the

superstructure which in general terms is considered to include all

structure below ground level but including the ground floor bed.

Superstructure and Primary Elements

Superstructure ~ can be defined as all structure above substructure

both internally and externally.

Primary Elements ~ basically components of the building carcass

above the substructure excluding secondary elements, finishes,

services and fittings.


51/66



52/66


Secondary Elements

Secondary Elements ~ completion of the structure including

completion around and within openings in primary elements.

Finishes

Finish ~ the final surface which can be self finished as with a trowelled

concrete surface or an applied finish such as floor tiles.

External Envelope

Functions External Envelope ~ consists of the materials and

components which form the external shell or enclosure of a building.

These may be load bearing or non-load bearing according to the

structural form of the building.
