The mission succeeded: a care centre for detainees that meets safety requirements and a nitrogen emission rate below the standard on site. The temporary care centre on the grounds of the Haaglanden penitentiary in Scheveningen was completed on 8 May. This achievement was made possible by the dpcp consortium, a collaboration between Du Prie Bouw & Ontwikkeling and cepezedprojects.
Lush greenery all around. The care centre for inmates is a stone's throw from the Natura 2000 area Meijendel & Berkheide, which has the status of a "protected nature monument". The Rijksvastgoedbedrijf deliberately chose to build here with low nitrogen, although this was not required at the time.

To minimise nitrogen emissions during construction, the process on the construction site was the main focus. For instance, we weighed up which (construction) materials were needed and calculated how much transport would be needed on the building site. 'The design of the care facility was adapted to this. It was also decided to build modularly on the building site,' says director Martijn du Prie. Du Prie is the contractor responsible for designing the facilities and building the temporary care facility. Cepezedprojects was responsible for project and process management.
For modular construction on site, the maximum size of a unit had to be calculated in advance in order to place the units on site with construction cranes. Du Prie: 'The construction site was small, so we could not use all types of construction cranes. We chose an electric crawler crane that can lift the heaviest elements. This crane also has the advantage that it can reach the furthest corners.'
In practice, there were quite a few challenges to tackle for minimal nitrogen precipitation during construction. The starting point was that everything on the construction site needed to be electric, but that was not always possible. Du Prie: 'The electric crawler crane broke down once. We had to resort to a diesel crane in order to repair it. And a diesel pump - with filters - was needed to pour the screed. These are unexpected issues during the construction project, which affect the total nitrogen emissions.
