A note from HJLCMS’s president and founder, Hugh J. Lofting, on open building methods… We, at HJLCMS, practice “open building” methods of construction. This concept considers a housing project is never completed; it is always under construction. In order to achieve these goals we think of ways to make access to electrical, plumbing and HVAC easy and adaptable in the building. One of the obvious ways to achieve this is to use “open web” floor joists. As long as there are access ports to the floor joists, it is easy to add mechanical and electrical needs in the future. Another principle of open building that comes into play is spanning the entire width of the buildings in order to reduce the need of bearing walls. This is also achieved with the open web floor joists.
