Analysis by object name:

Walls are bearing floors, colums are bearing beams, 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
