Sigma Modular Construction System Documentation
Welcome to the Sigma Modular Construction System documentation section of the website.
Sigma Modular Construction System is an open-source modular construction system developed by Transhuma and provided for free for anyone to benefit from.
We believe standards and modularity are the key to efficiency and long term development of anything that mankind does.
Instead of inventing a standard of our own and trying to force the entire world to adapt it, we decided to utilize the standard of intermodal (shipping) containers.
The 8ft module is compatible with an 8ft container in size, 5 of them in a row match the size of a 40ft intermodal container. The 20ft container is incompatible with the 20ft standard intermodal container because if you put 2 standard intermodal containers they don't match the size of a 40ft standard intermodal container. For the 20ft module, we had to choose between compatibility with 20ft or 40ft containers. We chose 40ft containers because we think they are more wide-spread. So two Sigma 20ft modules match the size of a 40ft standard intermodal container, but one Sigma 20ft module does not match the size of a 20ft standard intermodal container (but almost does).
Because the components used in Sigma system are supposed to be 100% re-usable, they need to be built from superior materials able to withstand a lot of stress that time and their usage bring.
The Sigma components are mostly composed of stainless steel, fiber-reinforced plastics, aluminum, glass, fiberglass, polyurethane and other durable, strong materials resistant to almost any weather conditions on Earth.
