Anton Constructiewerken in Amsterdam has made a floor fully usable, resilient and fire resistant for 60 minutes. We supplied and assembled steel to seal a floor recess. This project was a collaboration with Anton Constructie- & Adviesbureau and Anton Bouw- & Betontechniek. Anton Constructie- & Adviesbureau carried out the construction calculation and drawing work. Anton Bouw- & Betontechniek subsequently installed, poured and flattened a steel-plate concrete floor.
