Barcelona Under Construction: 200 Projects Test the City as BIM Could Speed Up Execution

Barcelona is undergoing an unprecedented urban transformation in 2025, with more than 200 simultaneous construction projects affecting both mobility and the urban landscape. These interventions, promoted by the City Council and other institutions, aim to prepare the city for the future through improvements in public transport, climate change adaptation, and the renewal of public spaces.

Major Projects and Impacts

1. Expansion of Line 8 of Ferrocarrils de la Generalitat (FGC)

  • The construction of the Hospital Clínic station has led to key road closures on Comte d’Urgell Street since January, affecting traffic between Rosselló and Còrsega. There are also disruptions in Francesc Macià.
  • Six-meter-high acoustic screens have been installed to minimize disturbances to residents.
  • BIM Application:
    • Multidisciplinary Coordination: BIM integrates structures, facilities, and project phases in a single model, avoiding conflicts and delays.
    • Traffic Simulation: Various detour alternatives can be modeled in advance, reducing unforeseen issues.
    • Noise and Dust Management: BIM analysis helps optimize the placement and design of acoustic barriers.

2. Rovira Tunnel Renovation

  • Closed in the downward direction since March, with detours via Avinguda de l’Estatut and streets like Tajo and Lisboa. Traffic lights at 22 intersections have been adjusted to mitigate the impact.
  • The project aims to improve safety before the tunnel reaches 40 years of operation in 2027.
  • BIM Application:
    • 3D Scanning and Digital Modeling: LiDAR scans can assess the tunnel’s current condition to plan renovations with minimal disruptions.
    • Traffic Optimization: BIM simulations help determine the best alternatives for signal adjustments and detours.

3. Plaça de les Glòries Transformation

  • The square is being transformed into a large urban park, with new green areas and social housing developments. Underground tunnels now channel traffic away from pedestrian areas.
  • BIM Application:
    • Underground Infrastructure Modeling: Prevents conflicts between service networks and existing tunnels.
    • Visualization for Public Engagement: Virtual walkthroughs can help residents understand how the park will look.

4. La Rambla Renovation

  • Sidewalks are being widened, traffic is reduced to a single lane, and traditional florist stalls have been temporarily relocated. The project is set to be completed in 2027.
  • BIM Application:
    • Optimized Construction Phases: A digital twin of La Rambla allows efficient coordination to minimize disruptions for businesses and tourists.
    • Urban Furniture Management: BIM helps simulate the relocation of market stalls to maintain business continuity.

5. Meridiana Avenue Renewal

  • Works between Felip II and Fabra i Puig aim to transform this road into a more pedestrian- and cyclist-friendly avenue with green spaces and reduced noise.
  • BIM Application:
    • Sustainable Design Analysis: BIM can evaluate noise, shadows, and wind impact to optimize green areas and urban comfort.
    • Cycling Infrastructure Coordination: Precise planning of bike lanes and safe crossings before execution.

Impact on Mobility

The large number of projects has led to significant disruptions for both residents and visitors:

  • Traffic Congestion: Road closures particularly impact private vehicle users, complicating daily commutes.
  • Rail Network Struggles: The critical state of the Rodalies commuter system adds to mobility challenges, with frequent delays at Barcelona’s access points.
  • Planning Tools: The City Council has launched an online platform where residents can check active construction sites, locations, and potential disruptions.

Iconic Projects

Beyond the immediate impact, some projects are reshaping Barcelona’s iconic landmarks:

  • Sagrada Familia: This year, a ceramic and glass cross will be installed at 172.5 meters, making it a new city viewpoint.
  • MACBA Expansion: Significant changes in Plaça dels Àngels will affect local dynamics, including the well-known skater community.

Reactions and Future Perspectives

The City Council acknowledges the inconveniences but argues that these interventions are essential to building a greener, better-connected, and more resilient city against challenges like climate change and urban growth. However, Barcelonians continue to face daily challenges in mobility and quality of life during this transformative period.

By fully integrating BIM technology, Barcelona could accelerate construction timelines, minimize disruptions, and enhance urban development efficiency.
