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
Panellised construction systems
Types of panels Open panels Closed panels Concrete panels
Composite panels SIPS
Oriented Strand Board (OSB)
Can you identify the 11-step process for the manufacturing of OSBs?
Advantages of using SIPs Pre-assembled from the factory Three times stronger than conventional stud walls Allowing for design flexibility Protection of the insulation material Using recycled wood chips instead of newly-cut lumber
Unitised curtain walling
Practical considerations for panellised construction system
Hybrid construction
Practical considerations for hybrid construction
Sub-assemblies and components Pre-fabricated foundations (e.g. ground beams) Floor cassettes
Roof cassettes Pre-assembled roof structure Pre-cast stairs
Practical considerations for sub-assembly
