Most structural systems treat their parts catalogue as a feature. CoGrid treats it as a liability.
Every additional part is one more thing the freight chain has to track, the build crew has to identify, and the engineering pack has to certify. So we collapsed the system to three: columns, beams, spreaders.
The trade-off is that each part has to do more. Columns carry vertical load and tie in spreaders. Beams carry horizontal load and index off the same bolt pattern as columns. Spreaders distribute load and brace against lateral movement. Designing them this way took years of iteration. Building them this way takes a wrench.
The result is engineering certainty that doesn't depend on the person fitting the parts. Which is the point — the structure performs the same whether the crew is on a residential build, a regional clinic, or a remote camp.
