Introduction
The construction industry is traditionally divided IStage involved in
into two sub-sectors which is construction of contruction
buildings and civil engineering. Construction industries
industry is very important to stabilize the country.
It is an area of business which covers building
work, civil engineering, mechanical, water supply,
electrical, quarries, and development of new
township, telecommunication and others. There
are three types construction of buildings which is
Residential, commercial buildings, and industrial
buildings. Types of Civil engineering construction
are Road construction, Bridge construction, Dam,
and others.

Introduction
There are three types of Government Government
procurement which is acquisition of works, procurement
supplies and services . Government
procurement is to support Government
programmes by obtaining value for money.
work procurement include construction and
engineering activities. The way to obtain the
work procurement through tender, direct
purchase, direct appointment, quotation and
others.

what is tender
Tender
statement from the client that provides information to the contractor about the
proposed project. The tender can be awarded either by competition or by
negotiation. The main function of a tender is that the client can select the most
qualified contactor to carry out the project.
( financial limit > Rm 500 000.00)
what is Quotation
Quotation
formal statement of promise by potential supplier to supply the goods or services,
required at specified prices, and within a specified period. A quotation may also
contain terms of sale and payment, and warranties. The quotation only for G1 and
G2 contractor.
( financial limit < Rm 500 000.00)
Page 11
Chapter 2
Types of tender
Open Tender
Open tender are offered to all contractors and normally the contractor with lowest
bid is selected. The client advertises a notice in the mass media to invite
contractors to proposed project.
Limited Tender
Client offered limited tender to the qualified contractor in the specified class
stated in the tender. Registered contractors are qualified to bid government
projects based on their financial limit or qualification class.
Selected Tender
Selected tender is offered only to a few contractors selected by the client.
Competition to bid the tender is only among the selected contractors.
Negotiation Tender
The client will select and give the tender form to the contractor based on

if the contractor reject the tender after extension of tender validation period. The
contarctor will be suspended and blacklist.
Page 17
Chapter 2
Rejecting of Tender
A contractor offers very high tender price, resulting in the client paying more than
the project financial allocation.
A contractor offers very low tender. There is a tendency for the contractor to find
ways to reduce the cost to prevent loss. It results in low quality project.
A contractor is still in the process of completing other project. Therefore, client
assumes that the contractor will not give full commitment to the new contract due
to financial capability, labour, plant and restricted equipment.
A contractor with unsatisfactory work record.
A contractor does not comply to the terms in the tender, such as hiring
unregistered workers to CIDB.
