We are two companies operating at opposite ends of the same industry – one developing and building the world’s greatest piling equipment, and the other designing and delivering bespoke piling and foundation solutions for structures around the globe.  

For the first time ever in the history of driven piling, we are accelerating the playbook on sustainability. We have combined our respective strengths and expertise in the pursuit of a new reality with the same mission: 

  • Contribution to sustainability without restrictions in performance or application. We are committed to building a world we want to leave for our children. 

The best collaborations are formed through a shared vision, and a drive to deliver customer success. The synergies were clear to us from the beginning; we are both passionate about creating better outcomes for our clients, and both hold a strong – and unified – vision for what the future of driven piling should look like.  

Together, we bring 119 years combined experience in the ground engineering industry. Our experience means that we are knowledgeable, client-oriented, and adequately skilled to provide our consumers with the best products and the best solutions, time and time again. Keep following – as ‘piling for the future’ is on its way!  

Aarsleff Ground Engineering AB support the construction industry’s roadmap 2045, which advocates that the construction industry should be climate neutral by 2045. Together, Aarsleff and the industry can influence society in the right direction towards a sustainable future.

According to research, the construction sector, including the property sector, currently accounts for one fifth of Sweden’s greenhouse gas emissions. As part of the Swedish government’s fossil-free initiative, the construction sector has developed a roadmap for a climate-neutral and competitive construction sector.

We interviewed Aarsleff Norway’s tender manager Jan Kreuziger on his view on sustainability within ground engineering.

Jan Kreuziger

Hi Jan. Tell us about your role at Aarsleff. What is your mission there?
Currently, I am the tender manager for Aarsleff Norway, and I have worked for Aarsleff Ground Engineering in four different countries since 2010, in roles such as site and project manager. My mission is to be a part of the change towards a more sustainable ground engineering industry.

Why are you interested in the topic of sustainability?
My interest in sustainability has been a big part of my life since I was a child and has mostly been focused on environmental topics. Spending plenty of time immersed in nature and natural surroundings makes everyone feel responsible for it and makes you want to protect it – whether it is resources, waste, or climate related.

How are you working with sustainability? 
Working mainly with tenders, I have very little direct influence on everyday choices in the field. However, I can certainly help clients choose more sustainable solutions.

Most recently, I have became a member of the sustainability working group of the EFFC (European Federation of Foundation Contractors), to be a part of the solution and work towards a greener and more sustainable industry.

How is the conversation about sustainability changing?
Just two years ago the deepest we came was sorting of waste and maybe emission standards. Now we have a goal of being climate neutral in 2045. If the ambition is too high or too low and how we get there can be discussed, but finally we have a goal.

How can the construction industry become more sustainable?
In my opinion, this is about the aggregation of marginal gains and taking small steps every day. There has long been a focus on reducing material-waste and recycling – (e.g., sheet piles) mostly because of the economic benefits. Since climate change has put sustainability into focus, and the demand for more sustainable solutions has increased, we must, and are able to, investigate other areas and the total/lifecycle impact of foundation works. Bigger steps can for example be taken, with the use of electric machinery or other major technological advances.

What challenges stand in the way of becoming more sustainable?
We are still in the early beginning of turning the industry around. If we don’t include everyone, from CEO to banksmen and from designer to developer and government, it will be hard to change anything at all. We need to demonstrate that there is no other viable alternative and continue to present all the positives, instead of only showing what everyone must change. For example, who doesn’t like clean water to fish in, healthy lungs because of less emissions from diesel engines and, a forest to walk in that is not burned down?

Are there any projects that Aarsleff AB has worked on that showcase your sustainability approach?
I think the reuse of sheet piles and other steel constructions, which Aarsleff is a champion in, is a good example of spending less money with a sustainable solution. Also, the energy pile is an interesting option to integrate a heating/cooling solution in the foundation.

What I often find underrated, but important in life-cycle considerations, is the overall quality of the performed work. Constructions installed to a high standard live longer than those that are installed without care and understanding of the total construction

Sustainable construction is often perceived to be more expensive, is that the case?
Firstly, this could be regulated with more requirements specified at government level, which would level the playing field.

Secondly, often money can be saved with sustainable solutions (Like Centrum Pile´s Energy Pile). Other solutions can often seem expensive when they aren’t. For example, investing in modern machinery; if less, or no diesel is used and you invest in careful operators and mechanics who give the rig a long life, costs can decrease. Also, the rising price of raw materials encourages us to discover better solutions.

Thirdly, the focus shouldn’t be on the costs right now for that it is too late. If society hadn’t waited this long to change their behavior towards greenhouse gases, we would be much better of in terms of the economic impact (It’s been a topic on the UN-assembly since the 70´s!). Essentially, the more we change “nothing”, the more it will cost.

How is technology shaping construction trends?
Trends come from both directions. Sometimes technology gives the construction industry possibilities we didn’t know we needed, other times the industry demands a piece of technology that is needed.

With better technology available we can make the industry safer, more sustainable and more productive overall.

Finally, what is one thing that you wish architects, developers, and building owners understood about sustainability?
This could begin with including constructors earlier in the process to find good, robust, sustainable solutions which might benefit other areas than just the foundations alone.

As a final note to our readers and clients, we welcome your challenging project requirements, and you can guarantee that we will always work hard to meet them! Without a goal, contractors are only competing on price. We should compete on sustainability too.
