SYSTRA Subterra has won the development of the Santiago metro in Chile with an assignment for Detailed Design Civil Works Shafts and Tunnels on Section 2 of line 8.

The project, which runs from the stations of Chile Spain to Los Leones over a length of 4.3km, includes the following main assignments:

• design and planning of the shafts necessary for the construction and ventilation of tunnels;
• development of galleries that connect different sections of the tunnels;
• Detailed engineering for the excavation and construction of the tunnels; and
• Complementary Civil Works, including all structures and systems necessary for the safe and efficient operation of the metro line.

The Santiago metro holds historical significance for SYSTRA, which first created plans for the system in 1968 and has played a key role in designing most of its lines. Line 8, spanning 19 km, is designed to enhance connections between the north-east and south-east of Santiago. The entire line will be underground, passing through six municipalities, and is set to benefit nearly 2 million residents, reducing travel times by almost 60%.
