QUALITY PLAN FRAMING FOR CONCRETE

1. QUALITY PLAN FOR CONCRETE

1.1. INTRODUCTIONIn order that the properties of the completed structure be consistent with the requirements

and the assumptions made during the planning and the design, adequate quality assurance

measures shall be taken. The construction should result in satisfactory strength,

serviceability and long-term durability so as to lower the overall life-cycle cost. Quality

assurance in construction activity relates to proper design, use of adequate materials and

components to be supplied by the producers, proper workmanship in the execution of works

by the contractor and ultimately proper care during the use of structure including timely

maintenance and repair by the owner.

Quality assurance measures are both technical and organizational. Some common cases

should be specified in a general Quality Assurance Plan which shall identify the key

elements necessary to provide fitness of the structure and the means by which they are to be

provided and measured with the overall purpose to provide confidence that the realized

project will work satisfactorily in service fulfilling intended needs. The job of quality

control and quality assurance would involve quality audit of both the inputs as well as the

outputs. Inputs are in the form of materials for concrete; workmanship in all stages of

batching, mixing, transportation, placing, compaction and curing; and the related plant,

machinery and equipment; resulting in the output in the form of concrete in place. To ensure

proper performance, it is necessary that each step in concreting which will be covered by the

next step is inspected as the work proceeds.

Each party involved in the realization of a project should establish and implement a Quality

Assurance Plan, for its participation in the project. Supplier’s and subcontractor’s activities

shall be covered in the plan. The individual Quality Assurance Plans shall fit into the

general Quality Assurance Plan. A Quality Assurance Plan shall define the tasks and

responsibilities of all persons involved, adequate control and checking procedures, and the

CHANDAN, HARI OM, PRASHANSA, SHASHANK, VIDHYAGROUP-III


organization and maintaining adequate documentation of the building process and its results.

Such documentation should generally include:

1. Test reports and manufacturer’s certificate for materials, concrete mix design details;

2. Pour cards for site organization and clearance for concrete placement;

3. Record of site inspection of workmanship,

4. Field tests; non-conformance reports, change orders;
