Design verification for Doha Metro Red Line project in Qatar


Project name: Doha Metro – (Red Line North Underground)
Date: July 2013
Length: 6 years
Client: ISG Joint Venture (Salini-Impregilo, SK E&C and Galfar E&C)
Size: 7 underground stations and 13.5km of tunnels
Location: Doha, Qatar
Designer: CIO Joint Venture (COWI, Italferr, One Works) 


Qatar Rail awarded ISG Joint Venture a $2bn+ contract to design and build seven underground stations between Musheireb Downtown and Lusail Marina, along with 13.5km of bored twin tunnels, 7m in diameter, to connect them. This project required full independent design checking. This task was given to SOCOTEC, which used completely independent analysis modelling and methodology.


SOCOTEC’s role was to verify that design documents met Qatar Rail’s requirements for the work and complied with relevant codes and standards. SOCOTEC’s design verification engineer (DVE) services also included inspection of the construction works in all project disciplines to certify the as-built documentation. 

Regular meetings and collaborative works took place between the project manager, technical coordinators and team leaders to ensure correct implementation of the verification process and compliance with Qatar Rail’s requirements. 

Over 20 disciplines were verified by  SOCOTEC including architectural, civil, electrical, fire detection and suppression, geotechnical, mechanical, quality management and risk management.
