Despite the significant development of automation in the manufacturing industry, the construction industry has not yet comparably gained much from automated processes. Fabrication of reinforcement rebar cages is one good example where automation has a limited application. Several challenges have to be tackled to introduce and take advantage of the automatic fabrication of reinforcement rebar cages. One important challenge is how and in what order the rebars should be installed one after another so that the fabrication of a reinforcement rebar cage is feasible. In this paper, we present our ongoing work towards proposing a method that gives a solution to finding the installation order of rebars.
