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
