Construction Analysis during the Design Process www.ddss.arch.tue.nl Bauke de Vries www.ddss.arch.tue.nl Bauke de Vries
2
www.ddss.arch.tue.nl 4D-CAD Linking building components with construction activities Manual task of the construction planner Dedicated systems: NavisWorks, 4D Suite, … Advantages: Simulation, Visualization
3
www.ddss.arch.tue.nl Challenge Automation of the planning process. Advantages: Independency from the planner Quick first concept plan
4
www.ddss.arch.tue.nl Implementation
5
www.ddss.arch.tue.nl Construction algoritms Analysis by object name: Walls are bearing floors, colums are bearing beams, etc.
6
www.ddss.arch.tue.nl Construction algorithms Analysis by object elevation: Object with a lower elevation is bearing an object with a higher elevation
7
www.ddss.arch.tue.nl Construction algorithms Analysis by directed graph: Each object is a node in a connection graph.
8
www.ddss.arch.tue.nl Construction algorithms Analysis by object adjacency: Each object is a node in a topological graph
9

www.ddss.arch.tue.nl Construction analysis The red object has in intersection with the green objects in the horizontal direction
13
www.ddss.arch.tue.nl Construction analysis Example: Objects adjacent to floor
14
www.ddss.arch.tue.nl Pilot study
15
www.ddss.arch.tue.nl Planning comparison Real planning Generated planning
16
www.ddss.arch.tue.nl Differences Concurrency whenever possible Unlimited resources Construction method
17
www.ddss.arch.tue.nl Complete process
18
www.ddss.arch.tue.nl 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
