The spiral fossil staircase is made of 4 main elements. The concrete pad serves mainly as the second step of the staircase while the wooden step is the first step of the staircase which is mounted to the concrete pad. The precast concrete steps are mounted to the carriage which is also cast of concrete.
The material of the precast concrete elements is Ultra High Performance Fibre Reinforced Concrete. The material has high ductility, low permeability, very high strength capacity in compression to standard concrete. Also, it is more durable and has a longer life span. This concrete includes fibers which allow to cast much thinner and complex forms while increasing the durability.
