SIGMA systemically manages resources, works, and services across all of its services, with the engagement of all employees and a focus on continual development. The basis of our quality management is to provide the services with a holistic approach by establishing customer-oriented and process-based systems.
The holistic engineering approach is the engagement of multiple disciplines in a project life cycle to produce coordinated design, organized construction works, and high-quality buildings.
Our services are for the cities, communities, and environment, specifically people and living beings. We act with this awareness in all our projects, and we are aware of our responsibility.
We make health and safety a priority. We aim to minimize the environmental impact where we operate and focus on health and safety in the workplace.
Wherever we work, we act with integrity to build trust and create a legacy. Integrity and honesty is the path we walk in our business.
We aim for a better life for our clients and humanity through an inclusive culture that covers all our employees. We respect the culture to which everyone belongs and provide a working environment where they can bring their individuality to work and reach their full potential, regardless of ability, age, ethnicity, religious beliefs, and gender.
