2
4D-CAD

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

3
Challenge

• Automation of the planning process.
• Advantages
• Independency from the planner
• Quick first concept plan

4
Implementation
5
Construction algoritms

• Analysis by object name
• Walls are bearing floors, colums are bearing
  beams, etc.

6
Construction algorithms

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

7
Construction algorithms

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

8
Construction algorithms

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

9
Construction analysis

• Object of anlysis

10
Construction analysis

• Move down

Construction analysis

• The red object has in intersection with the green
  objects in the horizontal direction

Construction analysis

• Example
• Objects adjacent to floor

Planning comparison
Real planning
Generated planning
16
Differences

• Concurrency whenever possible
• Unlimited resources
• Construction method

Experiences

• 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
