ENKA, in all of its company operations covering both corporate processes and projects undertaken that are carried out in the light of its vision; i.e. to be one of the best and innovative companies among the engineering and construction companies serving worldwide, and in line with its mission; i.e. to design, build and deliver safe, high-quality and cost-effective construction projects; has established, documented, implemented and improved an effective quality management system to ensure the achievement of the company’s strategic goals, to maintain the quality of the products and services it offers, to provide work efficiency, to do the work good and correctly, to complete the work on time-budget-quality, to ensure that the processes are carried out effectively, to ensure that the processes produce the expected results, to meet international quality standards, to establish an infrastructure for employee training and development, and to meet the needs and expectations of its customers-employees and stakeholders.

ENKA, together with all its functions; aims to create value and excellence in its works by cooperating with its employees, customers, business partners, suppliers, subcontractors and all other stakeholders. To this end, it has supported its employees in every respect, based on its mission of caring for people, and succeeded in disseminating quality to all its fields of activity.


“The ENKA Quality Management System defines the organisational structure, corporate policies and procedures, processes and resources that are deemed necessary to complete our work on time, on budget and to the intended quality.”




ENKA is committed to continually improve the effectiveness of the quality management system through the use of ENKA’s strategic direction, corporate quality policy, quality goals and objectives, the context of the organization, needs and expectations of the interested parties, process risk analyses, internal audit program, process performance monitoring and measurements, data analyses, corrective action program, and regular management reviews on quality.

ENKA’s Quality Management System is fully compatible with ISO 9001 and was certified for the first time in 2001 by BSI (British Standard Institute).

In addition to the ISO Certification, ENKA’s Quality Assurance Program which is necessary for the implementation of construction works, including engineering-design, procurement, quality control, contracting, fabrication or installation, in accordance with international standards, is also compliant with the American Society of Mechanical Engineers (ASME) Boilers and Pressure Vessels Code, and accordingly certified for the first time in 2013 by ASME.


ENKA believes that in order to perpetuate its existence to become even stronger, it needs to invest in each and every employee who possesses the knowledge and qualities needed in their field of work.

In this context, ENKA Academy was founded in 2015 to provide ENKA employee with opportunities to learn and develop their competencies, and to support the achievement of the company’s goals through the principle of continuous improvement, which is one of the requirements of the quality management system.

ENKA Academy is designed to develop the professional competencies, awareness of processes, technical knowledge and skills, social skills and their leadership and management skills  of ENKA employees.

Trainings, seminars, conferences and workshops in the ENKA Academy curriculum are delivered by ENKA staff or professionals with whom ENKA cooperates.


ENKA periodically reviews its processes and activities, conducts audits and evaluations in order to maintain its corporate processes and activities in a continuously developing, integrated and systematic structure and keep them up to date.

In this context, regular inspections and evaluations are conducted in conjunction with the internal audit team for the systematic evaluation of the performance, compliance, integrity and effectiveness of the company’s processes and activities within the framework of the requirements of international management systems, the company’s quality standards, corporate procedures, the relevant legislation and the labour laws.

Internal audits are carried out within the framework of an interval audit program. They are intended to identify potential risks and to to contribute to ongoing processes  and to identify the improvement areas.


Risk management is the leading priority in all ENKA’s processes and activities, and the habit of risk-based thinking is constantly encouraged by ENKA’s senior management.

The necessary mechanisms have been established, and the related procedures put in place in order to ensure that an effective risk management programme is implemented throughout the company, to determine the principles and methods on which this programme is to be based, to guarantee the continuous development of a corporate culture of risk management extending to all projects, units and individuals, and to conduct the risk management function effectively.

At every stage of the work, quality-related risks are analyzed and evaluated and process management is carried out in a coordinated manner with the risk committees within the company, by addressing the relevant risk issues according to the risk definitions, risk reduction methods and risk distribution structure.


ENKA has established a body of corporate knowledge for the purposes of conducting existing processes effectively, standardising the quality of its products and services across all locations, institutionalising the experience it has acquired since its establishment, perpetuating its corporate culture and clarifying its working rules and methods. This knowledge is made available via an electronic library accessible to all employees. All employees can access numerous international publications, magazines and library via this portal.


As stated in the first article of the Corporate Quality Policy, “Customer Focus and Feedback” is the priority of ENKA. In this perspective, ENKA seeks to ensure that customer satisfaction is lasting, and to maintain sustainable relations with its customers.

ENKA begins to value its customers’ views and expectation even before the contract is signed and identifies project requirements and the indicators that will allow for the monitoring of whether these requirements have been met in cooperation with the customer.

During the course of the project, ENKA provides its customers with a regular flow of information about the level of quality achieved. In this way it seeks to prevent the slightest question mark from arising over the quality of the product which it delivers.

In line with its customer-oriented approach to business, ENKA conducts customer satisfaction surveys upon the completion of projects and views this practice as one of the most important mechanisms for stakeholder feedback.  Survey results are treated as important data in improving process performance, system updating work and the formation of action plans.


ENKA strives to achieve the intended quality in construction through the use of proven process procedures, capable personnel, adequate planning, effective budget management, effective resource management, effective communication management, effective risk management, effective stakeholder management, suitable equipment and tools, current project drawings and specifications, applicable codes and standards, appropriate supervision and technical direction, sound construction methods, techniques, and practices.

ENKA verifies its construction quality through quality control, audit, inspection and surveillance, testing and monitoring of business activities.
