The present development strategies throughout the world demands formal quality management system as a necessary attribute for any business. The main objective of quality management system is to ensure that the management system to be proficient
When talking about the history of evolution of quality management systems; a large number of national standards were developed as a part of quality assurance in 1970s in the area of manufacturing, military and in industries. Later this was extended to service industries and professional organization.
But it was difficult to implement in the services that were granted by the building professionals like the engineers, architects, quantity surveyors. As it is not related to a product that is obtained from a manufacturing unit.
In order to develop formal quality management systems in construction industry, quality assurance and related are registered with certified bodies. They seek third party certification based on the ISO 9000 quality standards.
Among the ISO standards, the most relevant quality management system to be implemented in the case of a building professional is the ISO 9001. For contracting organizations, ISO 9002 is more relevant.

Understanding ISO standards
The quality management systems comprise the following standards.
1. ISO 9000: This section gives the guidance to select and use the Quality management and quality assurance standards
2. ISO 9001: This standard section helps in specifying quality assurance in different production stages. These stages include design, development, production, installing and the final service.
3. ISO 9002: This specifically deal with the quality assurance in the production and installation stage of the task.
4. ISO 9003: Quality assurance in the final stage i.e. the final inspection and testing stage is guided by the standard.
5. ISO 9004: Quality management and quality system elements is dealt by this standard. This form the last part of the ISO 9000 series.
The ISO 9000 standard helps in documenting quality procedures by providing accepted accounting principles.
Generally, the certification is given for two quality standards for a construction organization. They are:
Certification to ISO 9001
This certificate is provided for companies who carry out design activities as the major business operation. These companies carry out the design, development, production, installation and the final servicing.
Certification to ISO 9002
These are provided for the companies that does not carry out design activities. This includes production and installation.
There are twenty different areas a company have to focus and pass in order to get certified as a ISO 9001 certified company.
Interpretation of ISO 9001
To get a construction industry ISO certified, the following 20 requirements determined by the standard must satisfied:
- Management Responsibility
- Quality System
- Review of Contracts
- Control of Design
- Control of Documents
- Purchaser Supplied Product
- Identification of Product and the traceability
- Process Control
- Inspection and the testing
- Inspection, measurement and equipment testing
- Status of Inspection and the test
- Control of products that are non-conforming
- Corrective action
- Handling, storing, packaging and the delivery
- Quality records
- Internal quality system auditing
- Statistical Techniques
A clear idea on the quality policy must be stated by the firm to the management. Well defined responsibilities and duties must be established on the staff members who are involved in the quality management.
The management must also ensure that for the verification of the performance activities, the resources and the personnel are available when needed.

Handling, storing, packaging and the delivery
The products that are outgoing must be properly addressed. They must show no chances to bring any damage.
The firm must have the following storage of:
