Analysis by object name:Walls are bearing floors, colums are bearingbeams, etc.


Construction algorithmsConstruction algorithms

Analysis by object elevation:Object with a lower elevation is bearing an object with a higher elevation



Analysis by directed graph:Each object is a node in a connection graph.



Analysis by object adjacency:Each object is a node in a topological graph

DifferencesDifferences

• Concurrency whenever possible• Unlimited resources• Construction method


Complete processComplete process


ExperiencesExperiences

• Model preperation through clash detection• Generated planning 2 months longer than

real planning over a a period of 1 ½ year• Suitable for a quick first guess• Further development of: Construction

method, Humen resources, Material resources
