Degree of excellence a product or service provides.In other words we can say :Fitness for purpose Conformance to requirement Grade I. SuitabilityII. ReliabilityIII. DurabilityIV. SafeV. AffordabilityVI. MaintainabilityVII. Aesthetic lookVIII. SatisfactionIX. EconomicalX. Versatility

WHAT IS QUALITY ?

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

Every operation is connected with the quality of the product. In the case ofconstruction the quality of construction is to be maintained as per projectspecifications. It is important that quality requirements be satisfied and productionschedules are met. The satisfaction of the owner of the project is mainly derived bythe quality of the work.

Stiff competition in the national and international level of construction sectordemands a high quality oriented attitude of engineers. However, the managementis required to achieve the satisfaction of the owner by completing the projectwithin the cost constraints for the project. Both of these things are dependent onproperly integrating quality development, quality maintenance and qualityimprovement in construction. The integration of all these three aspects can beachieved through a sound quality control system.

QCIP CONTENT

ORGANIZATION CHART

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

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..

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.

The condition of store room should be well Level between cement bag and ground should be

considerably high The distance from wall and cement bag should be

around 30 cm In a column structure of cement bag no more than 14

The brick should be properly heated The brick should be strong enough if we throw from

even 1.2 m The edge of brick should be sharp If we clap with brick then sound comes out to be

metallic Texture of brick should be uniform Size of brick should be standard The weight of brick should be 2.7 to 3.1 kg
