Vektor.io brings together all project data in the Crown Bridges Alliance into a single view

25.8.2026

The Crown Bridges project is one of Finland’s most demanding tramway and bridge construction projects. The approximately 10-kilometre tram connection combines tramway, street, and civil structure construction within a large alliance project. Close collaboration between multiple design disciplines, contractors, and the client requires project information to be easily accessible and provide an up-to-date overall picture.

Within the Crown Bridges Alliance, Vektor.io serves as a shared browser-based interface where BIM models, as-built data, drone data, and geospatial information are brought together in a single view.

Making BIM models part of everyday project work

BIM models are widely used throughout the Crown Bridges project. Vektor.io has supported the project’s goal of making BIM models available not only for design and BIM coordination, but for the entire project organisation.

According to Heikki Putkonen, Design Manager at Sweco Finland Oy, Vektor.io has become a core tool in design coordination meetings between different design disciplines. It has been used particularly actively to coordinate water supply and utility designs.

According to Putkonen, the 3D view significantly improves the understanding of design solutions compared to traditional 2D drawings. It has also made it easier to present designs to project stakeholders.

In a project of this scale, Vektor.io also supports day-to-day work..

“Vektor.io acts as an extension of memory, especially for site managers, supervisors and design managers, who cannot be expected to remember every detail of a large-scale project.”

A shared view improves collaboration

Projects like Crown Bridges involve a wide variety of data from multiple sources. Vektor.io brings together project information from different systems and models into a single view, where BIM models, drone data and base maps can be viewed within the same coordinate system.

Miikka Gröndahl, Project Manager and Head of Information Management at the City of Helsinki, highlights the importance of maintaining a shared project overview.

“Vektor.io brings together project information from different systems and models into a single view. It makes it easier to understand the overall project and supports collaboration between the client, designers and contractors.”

A shared data environment reduces information silos and helps all project parties work from the same up-to-date project view.

Browser-based access makes BIM more accessible

On site, Vektor.io has made BIM models an integral part of everyday work.

“With its ease of use, Vektor.io made BIM models a natural part of everyday site operations and information sharing. In particular, the browser-based platform and the smooth user interface have received a great deal of positive feedback from users.”

– Juuso Kuusinen, Project Manager, Project Support, YIT Infra Oy

Since work began in 2020, the use of BIM models has expanded significantly. More and more people have incorporated BIM models into their daily work, regardless of their previous experience.

The browser-based environment also makes it easy to combine point clouds and orthophotos with design drawings, improving the overall project view and enabling information to be presented quickly through a single system.

As-built data continues to deliver value after project completion

The Crown Bridges Alliance has created post-construction as-built models for the completed project sections. Vektor.io serves as the platform where these as-built models are stored for future use.

According to Miikka Gröndahl, the as-built models provide valuable baseline information for future investments and follow-up projects while also supporting maintenance, asset management and infrastructure lifecycle management.

The as-built data will also remain available through the same environment during the alliance’s post-completion liability period.

Key benefits

• BIM models, as-built data, drone data and geospatial information available in a single browser-based view.
• A shared data environment for the owner, designers and contractors.
• BIM model use expanded from design into everyday site operations.
• A 3D view improves design understanding and multidisciplinary coordination.
• As-built models remain available after project completion to support maintenance and future projects.

About the project

The Crown Bridges project is one of Helsinki’s most significant public transport and infrastructure projects. The alliance is constructing a new tram connection between Laajasalo and Hakaniemi, the Merihaansilta Bridge, and the associated streets and infrastructure. The approximately 10-kilometre tram route will connect Laajasalo, Korkeasaari and Kalasatama with Helsinki city centre, significantly improving mobility and reshaping the city’s urban landscape.

The alliance partners are the City of Helsinki, Metropolitan Area Transport Ltd (Pääkaupunkiseudun Kaupunkiliikenne), NRC Group Finland Oy, YIT Infra Oy, Ramboll Finland Oy, Sweco Finland Oy and Sitowise Oy.

The project began in 2019 and is scheduled for completion in 2027. The estimated construction cost is approximately €326 million.
