This latest milestone builds on Ayesa Engineerings existing contracts for system supervision on the Line 3 extension and civil works for Line 7.

The new 27-kilometre route will serve two million residents, delivering faster, more efficient journeys across the city.

Ayesa Engineering, a global provider of engineering and technology services, has been awarded a key specialist advisory contract by Santiago Metro to provide project management support for the development of Line 9. This milestone further strengthens Ayesas role as a trusted partner in the expansion of Chiles most important mass transit system and builds on its ongoing work on Lines 3 and 7.

Spanning 149 kilometres, the Santiago Metro is one of the most modern and extensive networks in Latin Americaserving as a vital backbone of sustainable urban mobility. While construction of Line 7 continues and engineering for Line 8 progresses, planning is already underway for Line 9, backed by a USD 2.733 billion investment.

Ayesa brings extensive experience in mass transit systems, having delivered over 60 major rail and metro projects worldwide. Under this new contract, Ayesa will provide engineering management advisory services, counterpart engineering, environmental and community relations consultancy, works coordination, service change management, expropriation and easement management, as well as project planning and control.

The future Line 9 will be fully underground, adding 27 kilometres to the existing network. It will run through the districts of Recoleta, Santiago, San Miguel, San Joaqun, La Granja, San Ramn, La Pintana, and Puente Altobenefiting two million residents by substantially reducing travel times.

Line 9 will be the first in Santiago to feature a four-line interchange at Cal y Canto stationstrategically located at the edge of the historic city centre. Connecting with Lines 2, 3, and 7, it will serve as a major transfer hub with six interchange points, easing pressure on Line 4 and providing faster, more direct routes into the heart of the city.

The new line will comprise 19 stations, along with depots and maintenance facilities.

To integrate Line 9 with the existing network, some stations will need to be constructed at depths exceeding 40 metres, which presents a significant engineering challenge, explains Mariluz Ramrez, Director of Transport LATAM at Ayesa. Well need to design highly efficient vertical transport systems to manage heavy passenger volumes between Line 9, surface access, and connecting lines.

BIM methodology will be employed to coordinate all aspects of the project.

Fourth major contract win with Santiago Metro

In 2022, Ayesa was appointed to provide technical inspection services for the installation, testing, and commissioning of systems and equipment for the Line 3 extension. The company is also currently supervising civil works on sections 2, 3, and 4 of Line 7.

Additionally, Ayesa is supporting Santiago Metros digital transformation through a separate technology contract providing infrastructure services for its SAP ERP systemstreamlining user processes and improving administrative efficiency.
