•Linking building components with construction activities•Manual task of the construction planner•Dedicated systems: NavisWorks, 4D Suite, …•Advantages: Simulation, Visualization

ChallengeChallenge

Automation of the planning process.

Advantages:

• Independency from the planner

• Quick first concept plan

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
