It

cannot be used in basement construction

It

uses a large amount of steel reinforcements

It

is built for the core of a high-rise building

It

is used primarily for temporary structures

Primary

piles are installed without reinforcement

The lobby was decorated extensively with plywood artwork

The use of architectural plywood as the external cladding

The use of plywood along with glass panels to improve thermal insulation performance

The glass curtain wall panels fell due to thermal stresses and were replaced with plywood

The use of timber structure in the majority part of the building

Grade 1b

Grade 2

It usually is weaker than the Kentledge test

It cannot be done in an over water construction (offshore)

It is expensive

It is not suitable for certain types of piles, such as a steel H pile

It requires a lot of space

Continuous construction

Lower cost

Easier and safer operation

Faster setup

Greater weather resistance
