3. Degree of excellence a product or service provides.
In other words we can say :
Fitness for purpose
Conformance to requirement
Grade
I. Suitability
II. Reliability
III. Durability
IV. Safe
V. Affordability
VI. Maintainability
VII. Aesthetic look
VIII. Satisfaction
IX. Economical
X. Versatility
WHAT IS QUALITY ?

4.  Architecture view of any project should be good .
 Structure design should be good and safe .
 Testing of required material should be carried and confirm it feasibility in
use.
 Selection of material should be done according to structure.
 Methodology accepted according to Material .
 Workmanship should be good.
 Supervising of project should be done properly .
 Construction management technique should be used.
 Team who engage in construction have aim acc to quality conscious.
STEPS TO ACHIEVE QUALITY

5. Every operation is connected with the quality of the product. In the case of
construction the quality of construction is to be maintained as per project
specifications. It is important that quality requirements be satisfied and production
schedules are met. The satisfaction of the owner of the project is mainly derived by
the quality of the work.
Stiff competition in the national and international level of construction sector
demands a high quality oriented attitude of engineers. However, the management
is required to achieve the satisfaction of the owner by completing the project
within the cost constraints for the project. Both of these things are dependent on
properly integrating quality development, quality maintenance and quality
improvement in construction. The integration of all these three aspects can be
achieved through a sound quality control system.
REVIEW OF QUALITY

QCIP CONTENT

7. ORGANIZATION CHART

8. The necessary qualifications for QCIP staff should be established in
the QCIP and resumes for QCIP personnel assigned to specific
functions included in the initial submittal of the QCIP. At a minimum,
resumes should be included for QCIP personnel who have authority to
stop work or authority to recommend stop work due to adverse quality
conditions. The qualification standard can be based on existing
standards established by professional organizations such as ASCE and
ACI orthe qualification standard can be specified in the QCIP. The
information should be supplemented on a continuing basis by
submittal of qualifications of personnel actually employed.
QCIP DUTIES , RESPONSIBILITY, QUALIFICATION & AUTHORITY

9. The responsibilities of the various organizations involved with the
construction, such as the licensee, designer, construction management
organization, QCIP staff, testing laboratory and construction
contractor, should be addressed to provide an understanding of the
necessary coordination and relationship for construction of the
project. The services to be provided by each organization should be
clearly delineated and discussed.
CONT..

10. The responsibilities, duties and authority of key QCIP staff should be clear
and definitive, and should correlate with the organization chart. The position
description should contain such items as the job title; complete description
of all duties and responsibilities; authority, such as, authority to initiate a non
conformance report, authority to stop work and authority to recommend
stop work; responsibility relative to contractor negotiations and scheduling of
construction; and reporting authority. During construction, there should be
someone in the field at all times who has the authority to stop work. There
should be a separation of authority between the QCIP staff and construction
personnel. The principal QCIP supervisor in the field should have limited or
no involvement with contractor negotiations, scheduling of construction and
cost justification.
