Application of Quality in Construction Projects
Quality
is an integral part of the project Management
process. Management for Quality. Requires adequate
tools to achieve the intended objectives of the
project in the best possible results. Quality can be
simple expressed by fitness for Purpose. The systems
approach to quality consider the building process as
a set of activities starting ending user’s
satisfaction information system will be adjusted to
feed a date can be of great value to quality
improvement. The role of a quality control as a
production tool and a quality assurance as a
management tool. Economics of quality of conformance
is best achieve by minimizing the sum of the direct
construction and the quality cost. The quality
management approach start with the belief that
improvements is a way of life. Its principles should
apply in very branch and in every level. The aspect
of the overall management functions that determines
and implemented the quality policy is the
responsibility of the top management. Quality is
define is same different ways such as:
Quality
= evaluation, especially of materials products,
concentration of its use.
OR
Quality = evaluation pointed to appreciation,
especially, directed to persons.
OR
Quality = condition, function.
OR
The word quality to include “Quality which can
satisfy the requirements of the clients.”
“The
amount of adoption of the product-quantification’s
to the needs of using it”
Quality
sometimes defined in terms of strength, lifetime,
appearance, cost, use….etc.
The
common conclusion of Quality could be :
-
Judging quality is only possible when we do
relate products specification to factors of use.
-
The
same product, with the same specification has
different users.
The
main element of the dynamic cycle of quality
information system. It goes Through :
-
Collecting and analyzing the data.
-
Identify the quality problems and the causes.
-
Planning for elimination of causes.
-
Implement correct action

1. Quality Economics
There
are three ingredients to Quality Economics:
-
The
cost of skilled labor, equipment, materials,
methods and supervision to the product quality
output.
-
Replacing defect work.
To
optimize conformance cost of a given quality of
design one seeks to minimize the sum of the direct
construction costs and the quality control costs.

2. Quality control
The
quality control process includes:
Setting
specific standards for construction performance,
usually through the
-
Plans and specifications
-
Measuring variances from standards
-
Taking action to correct or minimize adverse
variances.
-
Planning for improvements in the standards
themselves and in conformance with the standards
in other words, once the engineers have set the
criteria for construction, quality control
ensures that the physical work conforms to those
standards.

3. Quality Assurance (QA)
For
construction projects, Quality assurance has
generally a broader meaning for the application of
standards and procedures to ensure that a product or
a facility meets or exceeds desired performance.
for, Construction Projects Quality Assurance has the
following definition. All those planned is
systematic actions necessary to ensure that the
final product will perform its intended function.
Quality assurance (QA) is a management tool. Quality
assurance can be thought as the design and control
application of set of product and process
verification procedures, both prior to completion of
the structure and during service, to ensure fitness
for purpose with on appropriately high
profitability.

-4. Quality Assurance process includes:
-
Third party approval (checking)
-
System audits
-
Advanced quality planning
-
Comprehensive quality manuals
-
Use
of quality costs
-
Involvement of non-production operations
-
Failure modes and affects analysis
-
Statistical process control
It is
also clear the Quality Assurance is an integral part
of all the building process stages, from inspection,
design, construction, commissioning, operating and
the use processes.

5. Total Quality Management (TQM)
The
philosophy of Total Quality Management is to make
the best use of all available resources and
opportunities by constant improvement Total Quality
Management requires that the principles of quality
management shall be applied in every branch and
every level in the organization. The Basic concepts
of Total Quality are as follows:
