Aarsleff BIZ Precast
Precast production on the largest scale
"We needed a ready solution and professional assistance with implementation. Both came with Maturix. We used two devices located in the area of lifting hooks to know the exact strength that is achieved there.”

About Aarsleff BIZ Precast
Aarsleeff BIZ, based in Swinoujscie, Poland is a precast company from a different scale: They focus on extensive prefabricated concrete elements for the construction industry. Thus, they combine custom-made solutions with more standardised precast elements with high cycles. The factory produces middle or big-sized elements for international clients, combine time, quality and money and offers the best solutions.
Challenges
High demands for product quality and fast cycles for great productivity are the main challenges for a precast factory.
The precast element curing process is a controlled situation compared to on-site casting. However, good and efficient timing is even more critical as lifting the elements and beginning the next cycle on time offers a high potential to improve productivity while ensuring excellent quality, leading to cost-efficient solutions.
For Aarsleff BIZ, lifting and moving the element from the mould as soon as possible is essential to start the next cycle. The early strength development determines the optimal time to move the element, and monitoring at crucial positions around the lifting hooks enables efficient and safe production without risking slippage.
For large projects, it is common to require temperature and/or strength monitoring, either with test specimens or concrete maturity solutions.
Key Challenges
- Optimizing the demoulding time of large precast elements
- Shortening the cycles but reducing the risk of damage
- Delivering temperature and/or strength documentation with minimal effort
- Test cubes do not 100% reflect the actual curing process in the structure and are a time-consuming and costly
Solution
“We knew that performance differs between cubes and the real element – so measuring directly in the structure provides us with more reliable results. Also, the automatic documentation saves us a lot of time and effort!”
Using Maturix, the Aarsleff BIZ team always knows exactly how the elements cure and if they must adjust the work schedule according to data. With the maturity system using the IoT network Sigfox, they can access the data anywhere. Alarms and automatic documentation ensure quality control.
Key Benefits
- Real-time insight into curing process
- Easy overview with Dashboard
- Automatic documentation
Results
The precast factory could cut their cycles even in half during the summer – leading to higher productivity and being able to deliver elements even before the deadline.
Before using Maturix, the workers relied on their experience. With the maturity system, the production got more regulated, and they gained confidence in lifting the elements on time.
Where possible, Aarsleff BIZ switched from using additional concrete samples to document the strength development to using Maturix – resulting in lower costs and less manual work.
Key Results
- Faster cycles and higher productivity
- Regulate production based on data rather than experience
- Reducing additional sample cubes
- Automatic documentation and reporting
"We were using sample cubes - but we knew the performance differs between cubes and the real element. We wanted to prove that we don't have to wait 4 or 5 days just because the sample result says so."

About Aarsleff BIZ Precast
Aarsleff BIZ is a precast factory in Poland and part of Per Aarsleff Holding A/S, the leading Danish contracting company. They produce big-sized prefabricated concrete elements for wind farms, bridges, harbours and many more. Large projects have incredibly high standards and requirements, as the applications are demanding and have to withstand extreme conditions; thus, the product quality and documentation are beneficial.
