BRIEFING EXPLORING DESIGNING CONSTRUCTING FINISHING

STACKING UNITS TEAM LCK_3C In this project, we seek to understand concrete by expounding on its properties and material poetics.

A concrete tower is tasked to be constructed by using modular proliferation. The operative performance of a module is explored through this project. Internally the module has a self-supporting, interlocking geometry. It would thereby achieve greater stability via inter-modular stacking.

Structurally, the theory of moment of inertia is experimented. This would mean that structural stability comes with a greater void at the base challenging common structural concepts.

Weight is of sensitivity at the same time. Concrete mixes of various ratios and alternative aggregate of lightweight materials are utilised to achieve optimum construction.

With all the above considerations in mind, this project therefore allows us to rethink concrete beyond its conventional perspectives.

INITIAL EXPLORATION: UNDERSTANDING QUADROR

The quadror is an efficient and effective structure by itself, Its versatility and interlocking geometry gives us a good point of departure in our design exploration. | PAGE 5

INITIAL EXPLORATION: MODULAR OPPORTUNITIES

In the exploration to redefine the conventional perspective of concrete, modules are stacked to attain a certain lightness.

The central space created from this proliferation is accentuated through a central void by creating a chamfer condition in each module. | PAGE 6

1. Initial formwork was made by enclosing the module’s perimeter. , However, it proved inefficient and not precise.

2. Precision is of paramount when cutting the angles required for the mould. Thus blue foams are utilised with the aid of the module templates and electric foam cutter to create the void. | PAGE 15
