Circular construction at Schiphol: BAM building checkpoint using demolition waste
Schiphol's waste-free ambitions take tangible form
At Schiphol, construction company BAM Bouw en Techniek has started working on a sustainable piece of craftmanship: a circular checkpoint. At this new checkpoint 90, individuals and vehicles will be checked by security staff. It is being constructed using materials left over from the demolition of three office buildings and three cargo buildings at Schiphol. The design is almost completely circular, which contributes to Schiphol's ambition to be a waste-free airport by 2030.
Demolition and design go hand-in-hand
In the design, created by Benthem Crouwel NACO Architects and BAM Bouw en Techniek, the demolition materials are leading in the material choices for construction. Existing steel structures, windows, doors, bathrooms, kitchens, LED lighting and facade cladding are getting a new home in the checkpoint. The design of the checkpoint is, based on the Building Circularity Index (BCI) score, 68 percent circular. The highest possible score is 80 percent.
At Schiphol, we have high ambitions when it comes to circularity. In 2030, we want to be completely waste free. That requires different ways of designing and building. Redevelopment and maintenance projects at the airport produce a lot of residual materials, and we want to use as much as possible in other projects. Checkpoint 90 is a unique example. The origin of the materials and the detachability of the design gives form to our ambitions and shows what is already possible.
The design team got involved right at the start of the circular demolition. An important factor, because then you can tailor the design to the collected materials. We often see design being put out to tender at a later stage. In this case, the processes went hand-in-hand. We're really looking forward to the next step in the creation of this new checkpoint. We are implementing BAM's 'Building a sustainable tomorrow' strategy in this project, with sustainability the key objective.
Materials not being recycled for the checkpoint have found other destinations. Bike sheds are being reused, window frames are being used in new buildings and even cable ducts are finding a new lease of life. What's more, the roofing is going to be processed and used to make asphalt for Rotterdam The Hague Airport.
Circularity at Schiphol
Schiphol aims to be a waste-free airport by 2030. Residual streams will be 100% reused or recycled, also in construction and maintenance projects whenever possible. When demolishing old buildings, we reuse as much of the material as possible, and we build circularly when using new materials. The source buildings for the checkpoint were demolished piece by piece and a record was kept of where the material came from and what state it was in. An architect then assessed the materials and (re)used them in new designs. Schiphol's circular ambitions focus on preserving scarce and recently produced construction materials, and on reusing them. An example of this is Schiphol's own concrete recycling plant, where concrete from renovation and maintenance projects is crushed and turned into new concrete or foundation material.
