During Hackathon@Staalbouwdag, multidisciplinary teams will compete in designing the best parametric steel structure in a workshop setting. The task is to design a steel structure where the main loadbearing structure and the structural details are in optimal balance.

Each team will consist of three members. Including one architect, one structural engineer and one structural detail-engineer. The team with the best design wins Hackathon@Staalbouwdag.

During the hackathon the use of Karamba3D is recommended.  Via the new tool KarambaIDEA, developed by Bouwen met Staal, steel connections of the parametric steel structure modelled in Karamba3D, can be exported to IDEA Statica Connection for detail analysis. Temporary licenses for IDEA Statica connection, Rhino6 (Grasshopper) and Karamba3D will be provided to contestants.


Hackathon@Staalbouwdag is looking for:

  • Architects
  • Structural Engineers
  • Structural Detail-engineers
  • The contestants have experience with either Grasshopper or Karamba3D or IDEA Statica connection


The Hackathon will start with presenting the teams and announcing the case. At the end of the day each will team will give a brief presentation of the made design.

The jury will judge the design on: Efficiency, Aesthetics and Build-ability. The team that scores best on all four criteria will win the Hackathon@Staalbouwdag. Every winning team member will receive a free Bouwen met Staal-course, or -study book.
