What role does the bentonite slurry play in diaphragm wall construction?
To keep the excavator heads clean
To prevent collapse of the excavation before filling with concrete
To reduce the volume of concrete required and therefore reduce carbon footprint
What type of soil improvement involves applying long-term loads to compress and consolidate the soil?

Small houses with many rooms
Structures requiring frequent modifications
What is a major advantage of using Cross Laminated Timber (CLT) in construction?
It is more flexible than steel in shaping complex designs
It can support spans of over 100 meters
It allows for fast on-site assembly due to prefabricated panels
It is completely fireproof
What is a key characteristic of a portal frame structure?
A rigid structure with minimal deflection
Use of lightweight materials for small residential buildings
Hinges and pins that reduce bending moments at the foundation
Columns and beams that support very short spans only
