The DreamCatcher Project was created during AEC Hackathon in Singapore on July 22-24, 2016. It uses Project Tango devices and Flux.io to quickly scan and shoot issues in a room, in order to boost productivity of the defects management process.

2. 2016
ONE PROCESS ON SITE : ISSUES MANAGEMENT
The contractor identifies defects that will need to be solved by sub contractors
Which is the faster, simpler and more reliable process to capture issues in this room ?

3. KILLER PAPER APPS
Example : FINALCAD

4. LET’S KILL BLUEPRINTS !
Dragging & dropping issues on blueprints is just tedious

5. TARGET THE ISSUE, AND SHOOT IT
Tango gave birth to Dream Catcher

6. INSPECTION REPORT FROM THE BIM
From FLUX, send back the issues to one 3d model, like Revit

THE INSPECTION SCENARIO REINVENTED
A new way to collect data on the field
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

8. 1 • JUMP INTO THE ROOM TO INSPECT
The room has been digitized
2016
Key notes
• A room appropriate for Tango 3d scanning,
from Whiskey team conclusions 5 months
ago.
• No need to be too accurate : defect
localisation with a +/- 10 cm error is fine.
• 3d model in Sketchup
• Integration in FLUX : project Dreamcatcher
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

9. 2 • MODEL CALIBRATION
Model & reality matching
2016
Key notes
• Need to find 2 points, identified in the BIM
model.
• One simple rule, based on the wall in front
of the door & 2 points at the wall
intersection.

3 • SCAN & SHOOT
Tango app prototype
2016
Key notes
• Start with the
floor_plan_example
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

11. 4 • EXPORTING THE DATA
Ready for FLUX
2016
Key notes
• Flux login feature, to send
data from Tango to Flux.
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

12. 5 • DATA VISUALIZATION
From Grasshopper & Rhino
2016
Key notes
• FLUX to move data from
Sketchup to Rhino
• FLUX to provide inputs for
the Rhino model
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

13. 5 • DATA VISUALIZATION
Point clouds
2016
Date captured
Location of defect
• (X,Y,Z), respective to room
origins.
Type of defects
• Categorization of defects:
floors, carpentry, plumbing
etc…
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

14. 5 • DATA VISUALIZATION
Defects follow up
2016
Based on date
logged in
• Within 14 Days
• 14 days < DATE <21 Days
• More than 21 Days
Possible applications
• Live monitoring of defects
team, for decision making
and quick response
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

15. 5 • DATA VISUALIZATION
Defect location
2016
Based on z-
Coordinate = height
• Within 0.5m (Floor Defects)
• Within Reach (2.3m)
• Require additional support >
2.3m (Ceiling Defects
Possible applications
• Facilitate deployment of
teams to tackle specific
defects
AEC Hackathon 3.4 • Singapore • JULY 22 - 24

16. 5 • DATA VISUALIZATION
Defects concentration
2016
Based on proximity
of points within a 1m
radius
Can vary depending on scale
roughly the size of a room
Possible applications
• Monitor defects in high
density residential buildings
• Visually identify
concentration of defects and
source of the problems
