Traditional concrete casting has been a popular method of building. However, buildings erected with such approach have a limited potentialities due the standardization of the formwork. However, such methods produce ample waste due to the use of exclusively custom formwork. This option is not reusable, thus unsustainable.

Saeculum allows users to compose their designs in economical, sustainable and eco-friendly methods through a circulatory workflow. In contrast to automated and autonomous systems, AR assisted fabrication links the connection between the maker and the materials in the context of design and manufacturing.

The Wave Function Collapse Algorithm is a constraint solving algorithm with a library, or libraries of tiles, where each tile has its coordinate properties. Saeculum’s space making system is separated into two scales - global and local. On the global level, the tiles are designed to form various spaces. It takes in the users’ inputs such as space type, number of occupants, space area, etc, and generates inhabitable spaces. The local scale serves as a pattern generator, allowing the user to generate different patterns according to their preferences and structural needs of the tiles’ aggregations.

These patterns are designed with the moulds being reusable. The designs are different variations generated by the same set of moulds reconfigured differently. Consequently, stainless steel moulds are more effective and efficient in a large scale construction, whilst aluminium moulds would be more effective on small scale constructions such as furniture.

The platform guides the users through the fabrication processes. The user commences by selecting the project. The platform breaks down the volume into smaller segments. The app provides a further breakdown of every selected tile into its respective molds for the users to navigate the fabrication process.

Saeculum utilizes AR technology for a real time exchange of information on the construction process through an augmented platform that provides instructions for the fabrication of formwork, the moulds’ assembly and subsequent casting of concrete. This aspect of the platform assists the construction workers on site and will be utilized via HoloLens.

Upon the completion of casting of a tile, the formwork is removed, and pieces are reused to create new casting templates, or form internal partitions.

The project aim is to explore new and efficient ways of concrete casting which deliver higher flexibility and ease of use. Since the design of the tiles are constrained by the WFC algorithm, other possible outcomes have not been researched that might possess more potentialities. MEP strategies require further research regarding this type of project in terms of efficient integration into the project.
