What are the drivers for offsite production?
Lecture Outline
Volumetric
Can you think of a type of project where it would
be crucial to use volumetric construction?
Would you live here?!
How long did it take to construct Container City 1
and how long it would have taken if constructed the
traditional way?
Container City 1
What could be the practical considerations
for volumetric construction?
Volumetric construction: bathroom and kitchen pods
Bathroom in a box
Practical considerations for volumetric construction (Pods)
Summary of Pod cost data
