Second Wind explores the potential of reusing pre-cast concrete elements from an obsolete apartment building in Helsingborg, Skåne County, Sweden.

As part of the ReCreate initiative, which encourages the sustainable repurposing of concrete components, I collaborated with Helsingborgshem, the city’s municipal housing company, to develop a new rowhouse typology of approximately 100 m², alongside a two-story multifamily apartment building on the same plot.
The project aimed to minimize modifications to the existing structural components, preserving their original form as much as possible while adapting them to new uses. The rowhouses, arranged in an L-shape with a southwest-facing courtyard, serve as rental units and highlight the potential of reused materials in creating modern, functional spaces. The apartment buildings, located on the north and south sides of the site, further demonstrate the versatility of these repurposed elements.

Throughout this process, I sought to maintain a connection to the original architectural context of the Drottninghög area, respecting its mid-20th-century character while introducing new, sustainable housing solutions. This project illustrates the significant environmental benefits and creative opportunities in reusing existing building materials, paving the way for more sustainable construction practices.

CROW is a Dutch organisation that gather and uncloses knowledge which is relevant for civil works and buildings. CROW officially launched the CROW-CUR Guideline 4:2023 “Reuse of structural precast concrete elements” on Tuesday (11-06-2024). This guideline provides a practical description of a working method that can be used in projects involving the reuse of structural precast concrete elements. It covers various aspects, such as preparations for deconstruction, the disconnection of elements, the temporary storage of elements, the assessment of rewon elements and the reuse of these elements in new structures. The guideline has a general section that covers topics that apply to reuse of all types of precast concrete elements. In addition, it has annexes in which specific products are highlighted . Currently, there are two annexes: annex A deals with reuse of hollow-core slabs and annex B covers precast prestressed bridge girders. More types of elements are going to be added to the guideline in the near future. The guideline is for both infrastructure and buildings, in the broadest sense of the word. Many aspects are the same for both, and the non-standard aspects are dealt with in the separate annexes.

TU/e, TNO and other experts, including contractors, engineering firms, clients and testing companies, contributed their knowledge, experiences and insights to shape the guideline. In this respect, the knowledge and experiences from the pilot projects of the Horizon 2020 project ReCreate were very valuable. The wide-ranging scope of ReCreate has helped shape all the guideline’s sub-sections.

CROW launched the Guideline on site at IJmuiden. Heidelberg Materials hosted the event and after presenting a quick overview of the guideline for a mixed audience, we all got a chance to check out the temporary storage (near Heidelberg Materials) for the harvested precast concrete bridge girders. Here, the girders are waiting to be used in new bridges at various locations in the Netherlands.

During my master’s thesis work over 15 years ago, I familiarised myself with precast production and its history in Finland. After that, precast concrete has been playing a role in one way or another in my work career. Many projects have involved either repairing precast concrete buildings or building new ones. Since the 1970’s, precast concrete production has formed a significant part of the Finnish construction sector. The systematic and ‘simple’ method provided a standardized way to build, and it quickly became very widespread. The precast concrete system has been criticized for producing a unified stock of buildings, reducing versatility in urban environment and suppressing designers’ creativity. Since the early days, though, the technique spread to erecting ever more complex and monumental buildings. It has been foundational for providing a fast and trusted way for building construction in Finland. There are thousands and thousands of precast concrete buildings here, and some of them are already slated for demolition. A part of the buildings suffers from degradation, but many are just mislocated from today’s point of view.

Figure 1. Finnish deconstruction pilot in Tampere, building vacated before the deconstruction of elements for reuse.

I believe that technical know-how is essential for creativity and enables responsible and sustainable construction. We must be more aware of our decisions’ environmental impacts when building new. Architects’ and engineers’ creativity is ever more challenged as we must prioritize sustainability values. Knowing the technical limitations and possibilities is crucial, so that creativity can be unleashed in the right place at the right time, and adverse uncertainties can be eliminated. Building new is inevitable in the future too, but we need to redefine ‘new’. We must apply regenerative thinking, create net positive solutions and aim for more ambitious circularity. The actions we undertake should have a positive impact on nature and the environment so that instead of consuming it, they restore and revive it. This is a leading value for Ramboll.

The prevalence of precast technology and the aim for a regenerative effect on environment are two leading thoughts that that drive our ambition here at Ramboll to examine and challenge the present business as usual in the construction sector. The headline’s statement inspires me and my colleagues at Ramboll Finland when we seek to find alternative ways to utilize what already exists. The built environment is a bank of building parts that has technically perfectly fine components stocked in it, preserved intact inside buildings. Only processes and systems to utilize them effectively are needed. I sometimes face people itemising reasons and obstacles why reusing building parts is way too difficult. I believe this pessimistic attitude may well up from the insecurity that follows from the building sector changing dramatically. There may also be a disbelief whether the huge leap, which is necessary, can be taken. Some of the items that the sceptics list are well known, some are relevant, and some are just fictional. We need to keep solving them one by one, showcasing with real-life projects that this is possible and acquire more experience to narrow down the gaping hole between the ‘old’ and the ‘new’ way of building.

An important milestone has been reached when the Finnish cluster finished the deconstruction of the pilot building in Tampere this autumn. We succeeded to reclaim several hundred hollow-core slabs, columns and beams intact, ready for use on next building site. It’s been encouraging to gain good test results, both before deconstruction, through a condition investigation, and after deconstruction, as some of the deconstructed elements have been load tested. All has been well from an engineer’s perspective! Now, the reclaimed building parts are being fitted into prospective new building projects. The search for the new building site has not been stalled because of any technical issues but rather by the currently poor market situation.

That final issue to solve – an important one indeed – is the business model that can support reuse. A circular business needs more collaboration among all the players in the field. Technically we are ready to say ‘yes’ to reusing precast concrete elements!

The success of the ReCreate project would not be possible without the expertise of the people that stand behind it. Our third interviewee is Simon Wijte – Work Package 2 leader and the Dutch country cluster leader. Ivan Fratrić of the Croatia Green Building Council will be conducting the interview. Here is his story:

Hello Simon and thank you for doing this interview! Can you introduce yourself and tell us about your background and role in your institution and the project?

Of course. I’m a full professor on the chair of sustainment of concrete structures at the Eindhoven University of Technology. My work is split between the University and a consultancy office where I already work for over 30 years. In both positions, my work is tied to concrete structures. I also take part in Eurocode meetings. In my consultancy office, I assess a lot of existing structures and damage to structures from which we can learn a lot. For instance, in 2017. a parking garage which was under construction near the Eindhoven airport partly collapsed and I performed forensic research to determine the cause of that collapse. I’m at the chair of sustainment of concrete structures since 2014. and my approach to this chair is more from a structural engineering than a material point of view, taking into account the application and maintenance of concrete structures in buildings. The material aspect is less relevant compared to a situation when you’re dealing with existing concrete structures in outside environments which are much more aggressive. When it comes to concrete structures, my belief is that concrete structures can be used again and again. The building of our faculty is now over 70 years old. A little over 20 years ago, it was renovated, a new façade, new plans and installations, but the concrete structure was maintained. Now already people are thinking of a new renovation which indeed can be done, but the concrete structures should be maintained again. You can do that over and over and in a way that can be challenging. That’s part of my chair. What you’re facing then is all kinds of problems because, obviously, you have to ensure structural reliability. I don’t know how it’s in Croatia and other countries in the consortium, but in the Netherlands, we’re not careful with the drawings of our existing structures. When you want to reuse an existing concrete structure and you have to assess the structural reliability, you would want to know what kind of rebar is in it, and if you do not know that, you try to investigate in order to find out. Those are the things I’m interested in my research and I receive more and more info about this through my work on the ReCreate project.

In your view, what are the professional benefits of working on the ReCreate project?

For starters, I have to mention Prof. Rijk Blok who sadly passed away and who got our university involved in the ReCreate project. He was an assistant professor in our unit on the chair of innovative structural design and since the topic of the project is closely tied to my chair, I got involved. Rijk managed the project, go us involved and made it successful, but after his untimely passing, there was a question on how should we continue with the project. At that point, it was already known that Patric Teufel would leave the university so I was basically the only one remaining. I took the task of being the Dutch country cluster leader and the task WP2 leader and it’s definitely a challenge. It fits the topic of my chair quite well, but the circumstances why it happened are very unfortunate.

That’s actually what I wanted to ask you because the Dutch country cluster experienced a lot of changes, from Rijk’s unfortunate passing and Patrick’s transfer – how did you manage to handle all of that?

There were actually more events than the ones you’ve mentioned that complicated things. When we entered the project, we thought we could have a pilot project of reusing concrete elements on our university’s campus. In the 50’s at the start of the university, there were four larger buildings and a temporary building built in the 50s. Those four buildings got renovated but the temporary building is still there. In that temporary building, there were some precast concrete beams and it was Rijk’s plan to reuse those beams in a fire station that would be constructed on our campus. That plan did not succeed so we had to look for another pilot project. With the help from our partners in IMd, we managed to get in contact with Lagemaat who are performing a challenging and huge pilot project which means that they are already commercially involved in something that is the topic of our project. All in all, personal changes to the project were followed with pilot changes which was challenging at the time.

It really mustn’t have been easy, to say the least. Now that you’ve mentioned the pilot, can you give more insight into the building itself and your role within WP2?

To be honest, if I had a choice, then work package 2 is something that I would not pick in the first place (laughs). It’s also not so much in my field of expertise, but we’re doing our utmost best for the sake of the project. What we noticed after Rijk passed away is that we’re lacking in staff and in knowledge as well. The Netherlands is not that big and we know each other quite well in the Dutch country cluster, so I looked around and found that a person I know whom was an expert in precast concrete elements, but just as I wanted to contact him, he started working with TNO just weeks ago. They obviously didn’t want to let him go, but since they are a knowledge institute, they were keen to participate in the ReCreate project. I’m of the opinion that adding them was a great move as they have great knowledge in terms of structural reliability, LCA, BIM models, and so on. Their participation in the country cluster opened up the opportunity to use their knowledge. Together, we managed to produce the deliverable for WP2, especially with their knowledge of BIM, which can be very helpful with everything we do in ReCreate. In principle, the basis of the project consists of two things, the first of which is the actual precast concrete element. But, additionally, to that, you want to have a lot of information about that element and those have to be connected to the element and have to remain that way so when that element is stored somewhere on the yard, you have to know all the relevant information about it. That is obviously in the domain of Work Package 3, but in Work package 2, before the deconstruction of the building, you have to know what kind of information is available on that particular element and for that, the BIM models are very useful because you can add a lot of information to those models and the challenging thing is that you can make a 3D model of the building that will undergo deconstruction with all the elements in it and then you can deconstruct it digitally, which means you can take them out and put them out into a database. We have to gain experience in that and connect with people with such knowledge as the BIM model and the database that contains all the BIM models of all the elements will be very important through the complete process. It will be important for both architectural and structural designers, as well as for LCA calculations.

That’s actually something that I wanted to ask you as I’ve asked Erik (Stenberg) the same thing. We know what kind of construction the ReCreate project proposes with regards to precast concrete elements and the benefits such as the reduction of carbon emissions and material extraction. That is good all by itself, but I asked Erik whether there are some drawbacks and constraints from an architectural perspective and he said that obviously you can’t do everything with precast concrete elements, so I want to see your perspective as a structural engineer and whether you see any constraints that such construction can have?

Let me touch upon the architectural constraints first. Normally, when an architect starts to design a building, he starts from scratch and its up to him whether the floor span will for instance be 7 or 8 meters. He’s free to choose it. It is completely different when you already have a complete structure after the older façade and separation walls have been deconstructed. When you go from an architectural point while having in mind the usage of precast elements, it’s kind of similar but you’re a little bit more flexible. Let’s assume you have a huge database of all kinds of precast elements that are available for reuse in new structures. Then an architect pays you a visit and says ”I want to make a building with, for example, 200 m2 of the ground floor and 200 m2 of the first floor and I want to see how I can create that using available elements”. That’s where the application that we are working on in WP5 is important as it will tell you the availability of elements in the database. In that sense, the architect has a degree of freedom but could be constrained by the availability of certain elements, as well as their location. In that application all kind of aspects can be considered. For instance, carbon reduction by reusing these elements is good, but if an element you need is in Rome and you have to construct a building in Amsterdam, then the reduction of carbon is gone. From an architectural point of view, when you want to reuse a structure in its place, the constraints are the largest. When you want to create a structure using rewon precast elements, you’re more flexible, but obviously, there are limitations, but those limitations can also be in your head.

And from a structural point of view?

We have to make a distinction between two parts. First on the element level. In the general situation, the elements which are available should be able to withstand the forces that will be applied to them in new structures. So that may not be so challenging until I’m not aware of the reinforcement which is there and I’m not aware of the function of the structure. The second thing is stability – there have to be some shear walls in the structure somewhere to keep it standing up. One of the last challenges is how do we connect the elements. What we see now through the ReCreate project is that disconnecting in majority of the cases is done by sawing structural parts apart and one of my remarks towards that we can do that also in ‘in situ’ structures and not limit ourselves to precast concrete. When demolishing in situ structures, you can also choose to saw off certain elements and try to use them again. ReCreate, as a project, is just the beginning of reuse and is also a small step towards the reuse of steel beams as well…

Now that you mention the reuse of steel beams, do you think that should be also focused on eventually? Do they go hand in hand with concrete elements?

When making the idea for the project, we limited ourselves purposely to precast concrete because if you expand the scope of research, it only gets bigger and bigger and more complicated and greatly expands in scope. But you’ve identified that correctly as the research can definitely be expanded to other things such as steel structures eventually as well. Research on that part is still ongoing. Research is also being conducted in the Netherlands on the reuse of precast concrete bridge girders.

That’s a topic for another project, maybe after ReCreate…

What you see is that a lot of things are ongoing and the tasks of structural engineers and architects is changing. I was educated only to design new structures.

It’s almost completely new science when it comes to ReCreate.

What we now have to do and what we have to educate our students is that in creating new structures, they should also keep in mind that reused elements can again be used or try to design new buildings within older structures.

Now that you mention the students…Simon, do you think that the knowledge that comes from the ReCreate project and the whole practice of reusing construction elements will be adopted and implemented into university curriculums?

It will and already is. I have some lectures on sustainment of concrete structures which is limited but what you see is that, when you look at master research projects done by students before their graduation, is that they are keen on carbon footprint of concrete structures and how that can be reduced. Because of that, we have a lot of students performing their master research projects within our ReCreate project. There’s one student at TNO looking at structural reliability when using reused elements, we have some students working on diaphragm action between hollow core slabs with particular connections so that they can be reused, and we have student looking after the reliability of non-destructive measurements after the presence of rebar, and lastly we also have a student working on how can we create new connections…

So there’s definitely a demand and interest for this topic?

Sure, students are very much aware of the problems we are facing with our environment and take this into account when choosing what they will master in.

Now that you’ve mentioned this, I’d like to return back to you. You’ve said that the students are highly motivated for topics that pertain to climate mitigation and reducing CO2 emissions. What I want to ask you specifically is whether you are a climate optimist or pessimist in terms of our goals for 2050.?

I don’t know whether I’m an optimist or a pessimist. I’m very much aware that things need to change. I try to be mindful of my personal behavior and preferences with regard to my own carbon footprint, but then again I will take a plane when I go for my holidays in the south of Europe. I still drive a car and will strive to buy an electric or a hydrogen one.

You’ve mentioned before that the ReCreate project circumstantially ended up in your hands. Now that you’ve spent some time with it, can you tell if you have any internal motivation or drive that underpins your work on the project?

Absolutely. The motivation for the reuse of concrete was already there from within my chair. I also must admit that the time I could spend on this topic was limited at the time, but ReCreate enabled me to expand the research. The topic in itself motivates me a lot as we need to work on the carbon footprint of concrete structures. The production of cement is responsible for over 8% of CO2 emissions created by people and that’s quite a lot. On the other hand, when you look at the Pantheon in Rome, the building, with a concrete structure stand there for more than 1900 years. Why do we have to demolish the concrete structures we make after just 50 years and create new concrete? We have to face the challenge that we have to reuse the structures that we already built. Reuse of whole structures is almost ideal, but the second best is definitely to dismantle it into reusable pieces rather than demolish it into coarse aggregate because then you have to use new binder and cement, at the cost of additional carbon emissions.

In your view, what is the ultimate goal of the project?

If the reuse of concrete elements in new buildings becomes regular within 10 years from now, then we’ve done a good job. We participate in it, produce new knowledge, and try it in pilot projects…if we are able to change the construction industry in this regard – that should be the goal. This goal will not come overnight even if people are initially for it, if we reach that goal, we’ve succeeded.

So a wider market uptake and a greater number of experts in these fields would be seen as successes of the project?

And also to improve processes for precast structures to make their deconstruction easier. On the other hand, I now have a student looking at a more sustainable design of precast structures of apartment buildings. If you make them easier to disconnect them, it requires less effort for reuse.

How do you manage and what are your thoughts on the collaboration within your country cluster and with other organizations in the consortium?

The cooperation within the Dutch country cluster is good and is getting better with time. I very much appreciate the collaboration with all the other country clusters because everyone is working from their own area of expertise and together we are able to gain all kinds of knowledge on the matter. It’s not just about structural reliability and structural design. It’s about LCA, material research, the digital design process, and so on. I appreciate very much how Satu (Huuhka) and Soili (Pakarinen) are managing this project.

We’re at the end of our interview and I’d like to end it with a personal question. Who is Simon Wijte when he’s not a professor and when he’s not working on the ReCreate project?

I like to do a lot of things. I like sports – both watching and performing. Although I’m becoming an old man, I’m 60 (laughs). I used to play field hockey, but my body doesn’t want it anymore. Now I’ve switched to cycling. I like a good dinner, a good glass of wine and being with my family and friends.

The success of the ReCreate project would not be possible without the expertise of people that stand behind it. Our first interviewee is Satu Huuhka – the project coordinator and the person most responsible for its inception. Ivan Fratrić of the Croatia Green Building Council will be conducting the interview. Here is her story:

I: Hi Satu! Can you introduce yourself a bit, tell us about your background, your role, as well as the role of your organization in the project?

Satu: I’m an associate professor of sustainable renovation at Tampere University School of Architecture. Tampere University is coordinating the organization and implementation of the project and I’m the scientific coordinator and basically the project is my brainchild as ReCreate was born of my initiative. I’m originally an architect and the topic of my masters degree was regarding the reuse of concrete or reusing different kinds of building parts and materials, but with a special focus on precast concrete. Interestingly, the inspiration for my masters thesis came from a relative of mine who sent me newspaper clippings of topics that I would possibly be interested in and one of those clippings was on the topic of reuse in Germany which I found the most intriguing and which incidentally described the work of professor Angelika Mettke who has worked on the topic for 20 years at that time and who would eventually join the leadership here on ReCreate. As for the idea for the project, it began with my colleague Jukka Lahdensivu who is the Work Package 4 leader and eventually ended up as multidisciplinary research, not just architectural and civil engineering, and employing a more holistic approach. My university supports preparing and coordinating proposals so I received a little grant to start building the consortium. Then we traveled to meet people from KTH and other organizations with whom we had previous contact and that we knew had suitable expertise to join the project. That’s how it started.

I: What was your initial idea when forming the consortium? What was the reasoning behind structuring it the way it is? How was the idea for the project received by the partners?

Satu: The idea for the country clusters was present from the beginning and was influenced by another project we are involved in which is called CIRCuIT which is coordinated by the city of Copenhagen but we’re a partner and a WP leader. I think that worked well in CIRCuIT and it made sense for ReCreate because we’re working with buildings, and construction is quite a local activity. It made sense to find universities to be country cluster leaders as they have the capacity to handle the management side of things, the bureaucracy, as well as because of their connections to the local organizations and industry partners that would address this issue in their countries. Everybody was really positive when they heard about the idea for the project and they immediately wanted to be on board, especially the universities. There was some difficulty with industrial partners as we had some talks with organizations that weren’t interested in the end, but our connections enabled us to find partners that wanted to be part of the project.

I: In essence, the universities immediately saw the potential of the project, while the industry needed more nudging in that direction.

Satu: The core activity of universities is research and development, but I think that industry partners were a bit weary of the bureaucracy which these projects entail. That is also why it was important to have these universities at the core of the country clusters to help the companies with the bureaucracy and to take the load off reporting away from companies as much as possible.

I: Of course, so they can focus on the development and implementation of the project.

Satu: Exactly, yes

I: Returning back to you. You said that the project is your brainchild and that it is personally very important to you. Why do you think, on a broader scale, the project is important and what is its ultimate goal?

Satu: It goes without saying that climate change is an issue, along with other environmental issues such as diminishing availability of sand and gravel in some locations. I think that now there’s a consensus in the construction sector that there’s need for change in the way how we’re building. Many European countries are even introducing legislation that requires low-carbon building – and not just with regards to the energy in operation. It is starting to be realized in the construction sector that manufacturing the materials for construction is also carbon intensive and that reusing building parts such as precast concrete helps to reduce that embodied carbon because in that case you don’t need to produce new material as you can just harvest existing elements from buildings that have been slated for demolition, which presents huge potential to cut embodied emissions as professor Mettke’s research has shown, and that’s the reason why we should look into reuse as concrete is used widely and is very carbon intensive as its a heavy material.

Satu Huuhka

I: You’ve mentioned the potential for the reduction of greenhouse gasses and the depletion of raw materials. Do you have any other aspects of the project that you personally find most exciting and compelling?

Satu: I’d say its the multidisciplinary approach that we have. It’s fantastic that we have all these experts in their respective fields, which includes practical experts of the industry partners. The fact that we have these pilot buildings is also really important as I found through my own research that we have reached the limit on what we can do alone as researchers without actually trying it in practice. Since now we have these pilot buildings, our experts can really put their thought into it and what can become reality eventually – not just in the construction aspect, but also in business, the environmental impact, the social impact and how work is changing, what are the architectural implications are, what it means for logistics and digitalization. Seeing all these experts work together is really inspirational for me as I feel that we’re really making a step forward with reuse thanks to all of their expertise.

I: There’s no lack of exciting aspects to the project, but its sheer scope and complexity surely brings some sort of challenges with it. In your view, what is the most challenging aspect of ReCreate?

Satu: Before we started, I already had a preconception that we might have a conflict of interest between the partners or that maybe there would be a risk that the industrial partners would change their minds on whether this is something worth pursuing, but these concerns were not realized at all. All the partners are really invested. The most challenging aspect actually is aligning the ReCreate project timeline with the real world building project timeline, because we don’t want to do something that isn’t really needed as we’d like for the pilots to be buildings that would stay, which is not the case with the Swedish pilot, but in principle, we would like the buildings to stay, so we need these real world collaborations outside of the project to find suitable building projects. That has been a challenge in many locations and we are still working on it. The timelines of building projects are variable – sometimes things happen quickly and in other cases things can stop for years and can then be picked up again eventually.

I: Do you think that negative impact is short-termed or that it could create further issues down the line?

Satu: It’s more about the moment we’re in as it reminds us here in Europe that it’s important for us to be self – sufficient with building materials to mitigate these supply chain uncertainties in the global geopolitical landscape, which also then creates a strong argument for reusing materials that we have here at home.

I: We’ve touched upon it a bit, but I wanted to hear more from your perspective. The ReCreate project entails four different pilots, from four different countries, with a multitude of organizations and companies involved. How do you handle the coordination of all of that as it must be a challenge in itself?

Satu: It is challenging and I’m really lucky that I don’t have to do it alone. Soili Pakarinen’s help as the administrative coordinator is really valuable because she helps everybody with the financial reporting and the country cluster leaders (the universities) are my main contact point to the industrial partners in the other countries and vice versa as sometimes there are language issues as it’s easier for people to operate in their own languages. It is a team effort and Soili, the country cluster leaders, as well as work package leaders are very valuable. So basically I’m not alone because I’m surrounded and helped by brilliant people.

I: The project is really ambitious and we’ll definitely have something exciting to show at the end of it. How do you see the future of the ReCreate project? What kind of impact would you like for the project to have?

Satu: I hope that the industrial partners will be able to integrate the ReCreate approach into their daily business activities and that they will be able to provide these goods, services and expertise. That is our main pathway to impact – that these products and services become available on the market through our industrial partners. I’m also dedicated to keep helping them through new projects if there are still things that remain to be developed. Personally, I’m prepared to help other companies that want to engage in similar projects. Of course, there are also open access documents and publication that will be available for scientists, industry people and even regular people interested in the topic.

I: Thank you Satu for the interview. To end on a more personal note – who is Satu Huuhka and what does she like to do in her free time when she’s not managing the ReCreate project?

Satu: I’m a very work-oriented person but sometimes I do other things in my free time. I like to cook, read detective stories like good-old Agatha Christie. When I have more time, I like to do something with my hands. For example, I live in a traditional wooden Finnish house and I do the conservation work with my husband. Things like window conservation and new felt roofing on the outhouse, as well as furniture conservation.
