The Holland Particle Therapy Centre offers a new treatment against cancer. The Rotterdam Erasmus Medical Centre and the Leiden University Medical Centre are closely cooperating with the Delft University of Technology to open the first Dutch proton therapy treatment centre, in 2016.
The HollandPTC is to treat about 600 cancer patients each year, of which children form an important part. Next to excellent patient care, HollandPTC will also provide education and room for innovative scientific research.

The compact building, designed by De Jong Gortemaker Algra Architects, offers a comfortable environment for patients, in which both research and optimal treatment can take place. The complex will consist of a so-called ‘courant’ section, mostly containing policlinic and medical imaging functions, office space and logistic areas, and an ‘incourant’ section, containing bunkers with specialized proton devices. These bunkers are made of heavy in situ cast concrete walls and floors of up to four metres thick.

The courant section has floors of hollow-core slabs and wide-slabs carried by integrated steel beams on prefabricated concrete columns. This forms a flexibly rearrangeable carcass work with floors capable of carrying heavy loads.
