My Construction Photos > Armored truck on International 4700 truck chassis/frame, Groton, Massachusetts, 2007.
My Construction Photos > Steel Construction: Bolted steel structural frame of steel wide flange columns, girders. Corrugated galvanized steel decking provides support for concrete slab floor. Ann Arbor, 2005.
My Construction Photos > Rough wood framing for door: Rough frame around door supports downward forces from floor/roof above. A double 2"x12" header supports short cripple studs that support double top plates that support floor joist(s) and the loads the joist(s) carry. Joists are engineered oriented strand board/wood I joists, consisting of 2"x4" top and bottom flanges, grooved and glued in center to an OSB (oriented strand board) vertical web. The doubled 2"x12" wood header/lintel is supported directly on the two studs on each side of the door. Multiple studs beside the opening replace the studs that would be in the wall if there were no opening. Pencil marks on the lower top plate indicate position of cripple studs (an “O” at edge and vertical line in mid-opening) and full height stud (“X”), and the number “24” on the header indicates it is to be erected at door 24 on the rough frame erection drawing.  Ann Arbor, Michigan, October, 2006.

My Construction Photos > Rough wood framing for window: Frame around window must support downward forces above window from floor/roof joists or roof trusses above. In addition, there must be a small gap above the window itself so that any deflection of the framing under load will not bear on window and bind or break it. The joists/trusses above will bear on the double top plate, which is supported by a doubled wood header/lintel, here 2 – 2"x10" boards set on edge side by side and supported directly on one of the two studs on each side of the window. The window will be supported at its bottom by the sill, which is supported by short “cripple” studs below it. The frame is sheathed on the outside with wood oriented strand board, OSB, which is then covered with Tyvek wall wrap, as can be seen through the window hole. Ann Arbor, Michigan, October, 2006.
My Construction Photos > Rough wood framing for door: Rough frame around door supports downward forces from floor/roof above. In addition, a small gap between rough frame and finished door frame prevents any deflection/warping of rough frame from deflecting/warping finished door frame and binding door. A double 2"x12" header supports short cripple studs that support double top plates that support floor joist(s) and loads the joist(s) carry. The joists above bear on the double top plate, which is supported by cripple studs supported by a doubled wood header/lintel, here 2 – 2"x12" set on edge side by side and supported directly on one of the two studs on each side of the door. Multiple studs beside the opening replace the studs that would be in the wall if there were no opening. Ann Arbor, Michigan, October, 2006.
My Construction Photos > Wood frame section: Wood framing for exterior wall of new residence. The frame is made up of sections/modules, each fabricated by butt nailing through horizontal (when in final position) bottom and lower top 2"x4" plates into ends of 2"x4" vertical studs spaced 16" oc (16 inches on center). Exterior sheathing from 4'x8' sheets of wood oriented strand board (OSB) is then placed on top of the horizontal frame section and nailed to plates and studs. The section is then pushed up vertically into its permanent position. It is nailed through bottom plate and plywood subfloor into underlying floor platform edge joist/band. A second 2"x4” top plate is placed on top of the first and nailed to it. A gray line surround on photo identifies a section ~15' long, and 4 light brown circles indicate the joints/breaks at the 4 corners of the section. The upper top plate bridges/spans across the joints between sections to provide continuity in the completed frame. A dark brown circle shows a joint/break in the top plate. Abutting this section to its right is another frame section that includes a large window opening. Ann Arbor, Michigan, October, 2006.

The frame is made up of sections/modules, each fabricated by butt nailing through horizontal (when in final position) bottom and lower top 2"x4" plates into ends of 2"x4" vertical studs spaced 16" oc (16 inches on center). Window and door openings are framed, nailing into place multiple studs at openings supporting header/lintel at top and sill at bottom. Exterior sheathing from 4'x8' sheets of wood oriented strand board (OSB) is placed on top of the horizontal frame section and nailed to plates and studs. The section is then pushed up vertically into its permanent position. It is nailed through bottom plate and plywood subfloor into underlying floor platform edge joist/band. A second 2"x4” top plate is placed on top of the first and nailed to it. A gray line surround on photo identifies a section ~11' long that includes ~ 6' wide window opening, and 4 light brown circles indicate the joints/breaks at the 4 corners of the section. The upper top plate bridges/spans across the joints between sections to provide continuity in the completed frame. A dark brown circle shows a joint/break in the top plate. Abutting this section to its left is another frame section. Ann Arbor, Michigan, October, 2006.
My Construction Photos > Wood frame: Top and bottom plate joints/breaks between residence wood frame modules. The modules to left and right of circled joints were framed and sheathed laying horizontally on the subfloor platform and then pushed up into position. The top plate was then nailed across the top and the bottom plates were nailed through the subfloor into the subfloor framing joists/band to provide sturdy support top and bottom for the frame modules. Ann Arbor, Michigan, October, 2006.
