Strengthening safe, fast connections and regional growth in Chile
At a glance
This new bridge, spanning 2 kilometers with dual tracks, connects the municipalities of Concepción and San Pedro de la Paz, replacing the century-old structure built in 1890. Its modern design enhances the frequency and speed of passenger and freight trains, driving economic and social development in the Biobío Region.
The challenge
Our response
Since 2017, we have contributed over 27,000 hours of engineering across two key phases:
Phase 1: Basic and detailed engineering:
- Development of four design alternatives with 3D models, budgets, and scheduling.
- Seismic risk studies, integrated drainage design, bike lane planning, riverbed management, and contingency planning.
- Detailed engineering of the final bridge design.
- Constructability analysis and preparation of bidding documents.
- BIM 4D modeling of the bridge, tunnel, railway tracks, and associated systems.
Phase 2: Engineering support during execution:
- Review and optimisation of third-party studies.
- Preparation of hydraulic and structural calculation reports.
- Resolution of technical disputes and generation of detailed plans.
- Review of contractor documentation and continuous improvement proposals.
The impact
This project represents not only a technical advancement but also a commitment to community well-being, offering:
- Connectivity: Reduced travel time between key urban centers in Greater Concepción.
- Modernisation: Enhanced train frequency and speed, aligned with current standards.
- Regional development: Strengthening of the Concepción–Curanilahue rail corridor and local economic growth.
- Social commitment: Integration of safe, community-focused engineering solutions.
This initiative reflects our dedication to continued development, safety, and community welfare. Our teams collaborated with contractors, seismic reviewers, and consultants to deliver a significant upgrade to municipalities of Concepción and San Pedro de la Paz.
