The road project in the Finnish town of Laihia, launched in autumn 2015 to improve the traffic arrangements and safety in the centre, is unique in many ways: no drawings or diagrams printed on paper are used for reviewing and commenting on the plans.
‘The Finnish Transport Agency, which commissioned the work, required extensive use of information modelling. For example, at the worksite meetings we work with a digital information model alone. For us as the contractor it is easier to see how the plans fit in with the existing structures. It’s a great experience to be involved in a project like this,’ explains Sami Immonen, Skanska Infra Oy’s project manager.
According to him, analysing the impact of the existing structures on construction work is easier with an information model than a paper plan.
‘For example, presenting the rebaring for a complex corner structure is almost impossible with adequate precision and detail in 2D, and some of the design work must be carried out on-site. Information modelling eliminates this problem. This is particularly evident in the on-site work as no time is wasted on sorting out the design details, and we can get cracking with the actual construction work. This saves both time and money,’ says Immonen.
‘When it comes to the digitalisation of construction sites, Skanska Infra is one of the frontrunners in Finland. As the information model was available to all parties and no paper copies were required, our designers could make the most of their expertise. With information modelling, you can produce extremely detailed plans. And precision has been of the essence in the project as some areas were particularly tricky to design. Using information modelling as a tool, we could achieve sufficient precision and ensure feasibility,’ explains Markus Ventola, head of AINS Group’s infrastructure engineering unit.
‘AINS Group has carried out most of their design work with the help of information modelling for a long time, and now we adopted the same approach in our construction operations.’ – Sami Immonen, Skanska Infra
Laihia’s road project was realised as a design/build delivery, a method that requires open and direct communications between the participants. The use of information modelling in design can provide a response to many of the challenges presented by this delivery type. For the Laihia project, the work processes and progress were planned as collaboration between the parties involved, enabling great flexibility in design solutions, which could be adapted to achieve the best possible outcome. Editing the model accordingly was also quick and easy.
‘This working method requires patience from the designers. As a contractor, we impose certain restrictions to ensure that the project fits in with our production,’ explains Immonen.
Laihia’s road project involves the construction of about two kilometres of new main road and the renovation of around 2.5 kilometres of an existing road. In addition, three interchanges, seven bridges and new, safer routes for cyclists and pedestrians will be built, along with about two kilometres of new noise barrier. The three operators participating in the project have access to the same design tools: Tekla Civil for road engineering and Tekla Structures for bridge engineering. Also, various construction stages have been evaluated at joint meetings. In design work, the goals have included seamless work processes and the cost-efficient use of high-quality construction materials and methods.
‘A large project is always a learning curve. In this project, all participants have enjoyed the opportunity to use their expertise to influence the progress at each stage. That brings additional precision to the project and ensures appropriate quality management processes on every level.’
Building success together: Finnish Transport Agency, Skanska Infra Oy, AINS Group Suunnittelu Oy
Accomplishments: Whereas the conventional process would have involved preparing a construction plan with a single realisation method, in this project various parties joined forces to identify the ideal solutions. All parties shared a vision of a project where information modelling is utilised extensively and seamless work processes are prioritised, which helped save time and money.
The construction design is now finished, and the process went well. The design process has progressed in a different manner than before as information models were utilised and approved by the commissioner.

The new main building, Aalto University, Espoo, Finland
The design for Aalto University’s new main building was selected through an architectural competition. The building will rise in an area of cultural and architectural importance. The building project will be carried out as a customised project alliance. In addition to the building of new teaching premises, the project involves the construction of a commercial facility, Metro Centre, that will be directly connected to Otaniemi metro station.
Information on the project:
- Gross floor area 33,800 m²
- Total cost 110 million euros
- A large proportion of the energy used by the building will be generated by geothermal and solar systems

Tampere University of Technology’s Kampusareena building, Tampere, Finland
The Kampusareena building of Tampere University of Technology represents a modern teaching facility that brings together students, researchers and companies. The complex houses a library that, together with lobbies, open learning environments and cafés and restaurants, forms an extensive open-plan space. AINS Group’s acoustical engineers used architectural acoustics modelling to study the way sound would travel around the space, enabling designers to optimise the selection of sound-absorbing materials and fabrics. The building also boasts an auditorium, which has received praise for its excellent acoustics that allow the speaker to be heard by those on the back row without the need for sound systems.
Information on the project:
- Cost 38 million euros
- Gross floor area 15,500 m²
- Integrated project delivery (project management contract)
- BREEAM Very Good-certified
- The building’s green roof serves as a recreational area.
- The project received recognition in the 2014 occupational safety competition and Skilled Landscaping Contractor Competition.
Tampere’s newest tower block and landmark, Luminary, will consist of two components: an eight-storey building and a 22-storey tower. A parking facility will be built beneath the yard area.
Luminary will house residential and business premises, complete with parking places. The project involves the use of structures for several particularly challenging designs.
Cost: 85 million euros (estimate)
Gross floor area: 18,000 m²
VTT Centre for Nuclear Safety, confidential, Espoo, Finland
The key project alliance model developed by Senate Properties in 2013 was piloted in the construction of the Centre for Nuclear Safety of the Technical Research Centre of Finland (VTT). The project partners gave positive feedback on the model. The project, which is partly classified as confidential, required the application of extensive user experience design processes and advanced moisture control technology.
