QUALITY DEFINITION:
Quality is the totality of features and characteristics of a product for service that bears on its ability
to satisfy the projects functional requirements. The quality of output is always agreed upon between
the supplier and the client (In project works, Contractor and the employer, respectively), and the
quality objective is to achieve zero defects with best quality of the project works. This is possible
only by ensuring quality control at every stage during progress of construction.
Quality is conformity to standards and requirements to achieve excellence. The following are some
definitions pertaining to quality and how to achieve it.
Quality control (QC):
POWER CONSTRUCTION operational techniques or a system of maintaining standards by
– Reviewing
– Checking
– Inspecting and testing.
Quality Assurance (QA):
POWER CONSTRUCTION planned and systematic actions and implementations necessary to provide adequate
confidence that the work will satisfy quality requirements.
Quality System (QS):
POWER CONSTRUCTION documented processes, which seek to provide satisfaction that the project outputs will fulfill all
the requirements for which it is being planned. Our Quality System fully incorporate the
organization, human resources, materials, equipments, processes, inspections, testing and other
parameters of the project. A key element of QS is the QA/QC Manual.
Quality Surveillance:
We are normally covering two aspects.
– At the project level, a review is required to ensure that the quality practices are
implemented and documented to ensure in relation to the quality system.
– At the contract package level, inspection and testing is required to ensure that the works
executed meet the required quality standards.
QA/QC MANUAL
Our QA/QC Manual focuses on the implementation activities of the project following contract
award, primarily on supervision and quality control of construction works. POWER CONSTRUCTION QA/QC Manual is
intended to be used as guide line for supervision of construction activities, primarily by the field staff
and the Design and Supervision Consultants.
It is providing a base outline towards, procedure, responsibilities, compliance acceptance criteria
and documentation for carrying out inspection, testing and reporting on various materials, items
involved for the satisfactory execution of the project work. In all cases, somehow, it is most
important to understand that the technical specifications as specified in the contract document /
agreement are the guidelines for any construction activity.
POWER CONSTRUCTION QA/QC Manual for the Construction activity does not attempt to suggest technical
specifications, since these are stated in the contract documents. Its aim is to ensure that the works
are executed as per specifications to achieve best results. Test results shall be interpreted as
applicable for individual package, in accordance with the technical specifications as specified in the
conditions of contract.
Key Parameters Of Quality Assurance
POWER CONSTRUCTION Quality system involves the various key tools which are generally practiced in the field for
Quality Assurance System. Our well designed quality assurance system will provide confidence that
the project outputs will fulfil all the requirements for which it is being planned. The quality assurance
system should have the following basic parameters.
– Site documents
– Mandatory and optional testing
– Availability of field and departmental laboratories
– Manufacturing test certificates
– Departmental team inspections
– Checklist guide for works
– Site inspections
– Post quality testing of finished works
– Quality certification
– Monthly reporting and review meetings
