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.
Quality = evaluation pointed to appreciation, especially, directed to persons.
Quality = condition, function.
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


19 – 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.


19 – 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.


19 – 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.


19 -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.


19 – 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:

  • User’s satisfaction (external and internal)

  • Never ending improvement

  • Control of business processes

  • Leadership and teamwork


19 -6. The total Quality Management process includes :

  • Aim for continuous improvement

  • Involves suppliers and customers

  • Involve all operations

  • Performance measurement

  • Teamwork

  • Employee involvement
