1
Construction Analysis during the Design Process Bauke de Vries Bauke de Vries

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 – Inleiding – Oriëntatie – Doelstelling van het onderzoek – De algoritmen – Implementatie – – Case Study – Reactie uit het bedrijfsleven – Conclusie en Aanbevelingen – Einde –

11
Construction analysis The green objects have an intersection in the vertical direction with the red object – Inleiding – Oriëntatie – Doelstelling van het onderzoek – De algoritmen – Implementatie – – Case Study – Reactie uit het bedrijfsleven – Conclusie en Aanbevelingen – Einde –

12
Construction analysis The red object has in intersection with the green objects in the horizontal direction

13
Construction analysis Example: Objects adjacent to floor

14
Pilot study

15
Planning comparison Real planning Generated planning

16
Differences Concurrency whenever possible Unlimited resources Construction method

17
Complete process

18
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
