The paper considers modular trihedral trusses of flat roofs for buildings with transverse division into pre-fabricated elements. The use of modular system is oriented to the mass production. The modular system delivery is carried out by various cargo vehicles. The main geometry calculations are given for the transportation modules and vehicles equipped with a crane. Variable design models of the trihedral truss modules are presented herein as well as the results of their static analysis. The different spatial positions and element's own weight values. Based on the results of the deformability assessment, the installation of additional temporary and permanent elements is substantiated. The engineering solutions are suggested for mounting the flat roof structures. Technical solutions are considered to provide the structural rigidity, module safety during the installation, storage and safe transportation.
