Abstract: A fitting for coupling an open upper end of a hollow section column to a support via which a building unit is to be supported on the column. The fitting comprises a body portion configured to be received in the open upper end of the column and rim portions that extend laterally outwardly from an upper end of the body portion so as to engage edge sections of the column at its upper end when the body portion is received in the open upper end.

Abstract: In a system and a method for managing production of prefabricated trusses and frames, production data during manufacture of a prefabricated truss and/or frame is collected, stored and processed to enable analysis of efficiency in the manufacture of the prefabricated truss and/or frame.

Abstract: A plurality of wooden roof trusses for constructing a roof includes first and second wooden roof trusses. Each of the first and second wooden roof trusses includes a bottom chord and at least one upper chord obliquely disposed relative to the bottom chord. A first web is provided to the first wooden roof truss and a second web is provided to the second wooden roof truss. Each of the first and second webs has a tapered web end shape set without regard to a shape of a first and second joint, respectively, into which said tapered web end shapes of the first and second webs fit. The first and second webs are substantially identical in length and web end shape. The first and second webs are located at different positions in their respective first and second wooden roof trusses.
