Maximum level of prefabrication. The manufacture at the workshop is much more productive than the construction site, and the quality has a much higher guarantee.

Easy assembly, no adjustments or corrections at the construction site.

Independence in the assembly order of the elements. This means that anything can be changed even after the assembly of the whole set. Assemble or disassemble any bar without considering the rest of the structure, so it is not necessary a preset order of assembly. This property is especially interesting for structures in which the concurrence of bars not confined to a half-space.

Accessibility to all space. In the same node may concur bars in any direction and the resistance capacity does not depend on the direction the bars are placed.

Mechanical properties of the knot that produce a performance as close as possible to the calculation hypothesis regarding the degree of stiffness of the bars in the knot, axial rigidity of the union, etc.

Great versatility of architectural and structural solutions. Assume the sphere as an optimum geometric body for its aesthetics, maximum degree of symmetry and equal resistance capacity in any direction.

Assure the aproximation of the calculation hypothesis with the real performance of the structure, given the rigidity that provides a spherical closed, seamless knot, and great relationship between wall thickness and diameter.
