Abstract: A flooring member for use in constructing a floor surface comprising an elongated structural member having at least one, relatively flat, vertically-extending support portion enabling said flooring member to withstand relatively heavy loads without substantial bending, said flooring member consisting essentially of glass fiber reinforcements and a suitable polyester. Preferably the member is constructed by pultrusion and includes a top portion having a substantially flat upper surface suitable for forming the floor surface, the support portion being integrally connected to the bottom of the top portion.

Abstract: A building is quickly erected on the site, by preparing a footing below ground level, erecting at spaced apart distances around the footing a plurality of vertical pre-cast, combined foundation wall and side wall panels of U-cross section which have load bearing vertical side edge flanges and may include a parapet section and then welding infill panels containing windows and doors between the load bearing vertical, side edge, flanges of the panels. The vertical side flanges of the one piece foundation and side wall panels form reinforced colums and the space therebetween may be used as air ducts, pipe chases or the like.
