Highway E39

Largest infrastructure project in Norway

“Before Maturix, we planned, adjusted, and decided mainly based on our experience leading to rather conservative decisions. Now, we can work more efficiently and ensure safety based on data.”

Project Leader, Kruse-Smith

The E39 is a 1100 km long highway along the Norwegian coast. Today, it takes around 21 hours to drive this route including seven ferry crossings. With the ongoing E39 project, it is going to be possible to drive the whole distance in 13 hours without the need of using a ferry. That is why the project is also known as Ferry Free E39 as many ferries are being replaced by tunnels and bridges.

Kruse Smith is responsible for concrete work of 19 km between Kristiansand West to Mandal East with 8 dual lane bridges and other additional smaller constructions. 


The entire project of the norwegian highway E39 is scheduled for completion in early 2022 – good time management and well thought-through processes are required to successfully complete the project and meet the deadline within the strict schedule.

Deep fjords, high mountains and a harsh climate – these are challenges for infrastructure construction on the Norwegian coast.

For this extensive infrastructure project, resource coordination and time management are crucial. Project management is demanding, as resources must be optimally distributed among the sites to maintain efficiency and productivity, while natural environmental and weather conditions pose a challenge.

Key Challenges


The Maturix In-situ solution provides Kruse Smith with an end-to-end tool for concrete strength monitoring.
By using thermocouples that are cast directly in the structure and connected to a transmitter, the temperature inside the concrete is measured continuously. The data is sent wirelessly to the cloud platform. The software automatically calculates maturity and strength based on the history data and the concrete mix and the strength development process can be followed. The data is accessible from any device, thus smartphone, tablet or computer with internet connection via the web portal or app and provides Kruse Smith with real-time insights into the actual curing status inside the structure in several positions for each cast.

Key Benefits

“Using the Maturix system is very intuitive. I find it easy to use, making my quality control much faster than before. It saves me a ton of work and time, both in terms of collecting data and managing it.”– Marius Røksland, Quality Team, Kruse Smith


By using Maturix Kruse-Smith on the one hand, ensures that the required strength has been reached while on the other hand, the tough time management for the extensive infrastructure project is met. Getting insights into the curing status turns into the basis for decisions and proactive attitude while keeping the overview and having an automatically digitalized solution for temperature monitoring at hand.

Key Results

“Adapting project schedules continuously and aligning the workflow are keys to the success for this project. Maturix convinced us with its precision and it’s easy implementation – and we are now using the system for many of our projects to follow the curing and taking key decisions based on data. The monitoring directly in the structure gives us safety while we can keep up with the schedule and ensure delivery on time.” – Asbjørn Stålesen​, Project Leader, Kruse-Smith

E39 Coastal Highway Route project

About E39 Project​

The Coastal Highway Route E39-project is the largest infrastructure project in modern Norwegian history. With 1100 km connecting Norway from Kristiansand to Trondheim, the project is challenged by Norway’s landscape and weather conditions. The project is ongoing and is planned to be finished in Spring 2022.
