If you’re looking for a construction contractor who blindly follows orders, Mahieu Construct is not the right place. Thinking along to find the best solution, equipped for both steel and concrete, and always putting the client at the center—that’s where they excel.
Mahieu Construct is a general contractor for commercial buildings, with expertise in areas including logistics and storage facilities, production halls, and office spaces. The company has been active for 35 years in sectors such as industrial and agricultural construction, operating in Flanders, Wallonia, and Northern France. “Our headquarters are in Comines-Warneton, but we also have a physical presence in Mechelen,” says CEO Felix Mahieu. “The customer is central, so we want to always be close to them.”
Always the Best Option
The customer-first model is deeply ingrained in Mahieu Construct. It’s the main reason why the company has long invested in two different materials, while competitors often choose to specialize in just one.
“We have two of our own steel workshops as well as a workshop for prefabricated concrete panels and columns,” says Felix. “That allows us to produce whatever the client wants. In most construction projects, a choice is made between steel or concrete. “Both materials have their own advantages, but they can be used together perfectly,” he explains. “Concrete is highly fire-resistant, but steel allows for more architectural design flexibility.”
Building Together
Beyond practical considerations, this combination also makes the process more affordable for the client. Felix: “We have greater control over production and, thanks to vertical integration, can estimate the total cost much more precisely. It also gives us the opportunity to try new things and offer innovative solutions to our clients.”
At the heart of Mahieu’s DNA is the motto ‘building together.’ “And we truly mean that,” he says. “We collaborate with the architect and engineering firm, but also with the client themselves. Is what they have in mind really the best way to achieve the desired outcome? We also keep our lines of communication very short.”
This results in a smooth process from project start to completion. “We have a lot of in-house expertise that makes the process as painless as possible. Take loading and unloading docks, for example—those involve very specific requirements. Their construction essentially starts with the foundations, which means our salespeople already need to have a strong understanding of the client’s needs and wishes from the very beginning.”
Long-Term Sustainability
In response to changing climate conditions, Mahieu Construct has increasingly focused on sustainability in recent years. Recycling, waste separation on construction sites, the choice of materials and how to recycle them… “It’s not always easy to become more sustainable in our sector,” Felix admits. “We manage to do so by thinking long-term. We look for materials that can be maximally recycled, and above all, we aim to build in such a way that our clients won’t need to think about recycling for a long time.”
Looking Forward to Transport & Logistics
This October, the Transport & Logistics fair will once again take place in Antwerp, this time co-hosted with the breakbulk expo AntwerpXL. “We’re really looking forward to it,” says Felix. “We’ve already completed many projects in the Flemish ports, and it’s always beneficial to be present to reconnect with all our contacts. You meet only your target audience there—that’s always interesting.”
“We’ve participated in about four editions so far and have always been pleased with the results. It’s also always an enjoyable experience, made possible by strong organization.”
