My Construction Photos > Precast concrete tilt-up construction: Reinforced concrete wall section was pulled up at its top by crane into near vertical position to form section of outside wall of building. Worker uses impact drill to make hole in slab into which to bolt bracket that supports diagonal shore/brace to hold wall up until roof structure is in place. Phoenix, Arizona, November 2006.
My Construction Photos > Precast concrete tilt-up construction: Reinforced concrete wall section has been pulled up at its top into near vertical position to form section of outside wall of building. Wall section is heavily reinforced concrete that was cast in horizontal position on top of floor slab of building, which alleviated the need for wall forms. It is lifted by steel cable, hooked to wall at a 8 points to provide force sufficient to break wall free from the slab beneath it and lift it into its final vertical position. Two point support from lifting beams/ harness and pulleys provide independent support to each lifting point. Pipe with screw jacks at end align the wall and support it against wind forces. Workers 3, 5, and 6, from left to right, hold chain/cable with which they will jerk out pens locking the lifting cables to the slab wall, and they will next pull to withdraw pens to separate lifting tools from the wall. Phoenix, Arizona, November 2006.
My Construction Photos > Placing concrete with concrete pump: Concrete shoots out end of elephant trunk in a stream of concrete directed by the worker at the left into wood forms, where it joins with the reinforcing steel to create horizontal foundation beams. To the right a second worker inserts and withdraws a flexible concrete vibrator that helps consolidate the concrete. Behind him a worker carries on his back the motor that drives the vibrator. In background is temporary support wall, consisting of vertical steel soldier piles/beams that support wood breast boards that support the soil of the vertical soil embankment at the edge of the excavation. Soldier beams are supported at mid-height against lateral movement of soil by steel rod tiebacks, shown here with orange steel plates. Colorado Street, Denver, Colorado, December 4, 2006.

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 > Concrete construction, road/street construction: Advance concrete readymix truck places concrete through its front chute into forms for street curb. The two workers bent over are rough forming the vertical curve of the curb shape, using a piece of 2"x4" lumber. Huron Parkway at Huron High School, just North of Geddes, Ann Arbor, Michigan 2005.

The two workers are shoveling concrete to form the curb's vertical curve. Worker on right is placing concrete for curb height using concrete he took from the lower placed concrete. Worker on left is rough-sculpting the concrete into the vertical part of the curb. Huron Parkway at Huron High School, just North of Geddes, Ann Arbor, Michigan 2005.
My Construction Photos > Deep basement construction safety: Workers and equipment placing concrete at base of deep basement excavation are protected by tied-back soil support system against cave-in of soil side-wall. Timber breastboards support soil. Vertical steel soldier-beams (not visible behind breastboards) support breastboards. Steel tie backs support soldier-beams. Ann Arbor, 2003.
