Doha Metro

Design verification for one of the world’s largest metro systems.

Client

Qatar Rail

Project date

Appointed 2013

With over 100 stations and more than 219 kilometres of rail line, the Doha Metro is one of the largest infrastructure developments in Qatar and among the most extensive metro systems globally. Zutari was appointed in 2013 as the design verification engineer for the Red Line South Underground section—one of six major components of this transformative project.

The opportunity

The Red Line South Underground spans 16 kilometres of twin-bored tunnels, featuring multiple cross passages, five underground stations, switchboxes and emergency exit shafts. It connects with other lines in the network, including the Red Line North, Green Line and Gold Line.

The scale and complexity of the project required rigorous design verification across multiple disciplines, ensuring compliance with local standards and international best practices.

What we did

Zutari’s consultancy services included:

  • Design verification of bored tunnels

  • Geotechnical, structural and architectural reviews

  • Mechanical, electrical and plumbing (MEP) design verification

  • Fire and life safety assessments


Special attention was given to geotechnical aspects, as all concrete elements had to meet strict durability standards due to Doha’s high salt levels in air and water. Materials were carefully assessed to mitigate long-term deterioration.

Coordination was critical. With numerous contractors, consultants and project managers working simultaneously, regular workshops were held to align designs with Qatar Rail’s evolving requirements and maintain professional integrity throughout the development.
Close collaboration and accelerated turnarounds ensured success on one of the world’s largest metro systems.

The outcome

Zutari’s involvement helped ensure the safe and timely delivery of a key section of the Doha Metro. The stations feature a unique architectural style inspired by traditional Bedouin tents, blending heritage with modern functionality. The metro will serve as a vital transport link for the 2022 FIFA World Cup™ and support the development of new urban hubs across Doha.

The Doha Metro is more than a transport system, it is a symbol of Qatar’s ambition and innovation. Zutari’s role in verifying the design of the Red Line South Underground reflects its commitment to engineering excellence and collaborative delivery on world-class infrastructure.

Close collaboration between stakeholders and accelerated turnarounds were essential to the project’s success.
