My Construction Photos > Placing undeground concrete: Concrete bucket is being filled by direct chute from concrete ready mix truck. Caterpillar 345B backhoe has backed down slope toward underground utility tunnel into position to lift concrete bucket and rotate 180 degrees into position to place the concrete in the utility tunnel. Access to the utility tunnel construction is behind backhoe, by ladder. At upper left of photo is cylindrical manhole surface access to tunnel. Mott Childrens Hospital, University of Michigan, Ann Arbor, Michigan, May, 2007.

My Construction Photos > Laydown concrete bucket delivers fresh concrete through its bottom gate valve to worker powered concrete buggy at building floor edge. Worker operates gate valve lever with right hand. Bucket is supported by crane. The natural tilt of the laydown bucket allows it to extend inside the floor edge, held in place by the wire cable perimeter fall protection, in this instance. Worker will push concrete buggy to concrete placement position and tilt it forward to place its concrete, and then return to this point to load additional concrete. Ashley Terrace, Ann Arbor, Michigan April, 2007.

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 > Concrete construction/readymix/placement: Advance front-discharge ready-mix concrete truck delivers and places concrete in trench. The mechanisms that position the concrete placing chute are all controlled by the truck driver from his driving position, which allows him to continually position truck and chute in the best placement location while placing concrete.
Chute control mechanisms include the following: 1. Top of chute, where concrete is fed into chute, can be rotated horizontally through 180+ degrees with horizontal chain drive around chute top gear, to place concrete at any angle to side or in front of truck. 2. Hydraulic piston at vertical angle from truck front center supports and positions 1st section of chute vertically. 3. Hydraulic pistons parallel to chute on both sides at joints between sections 1 and 2 and sections 2 and 3 fold chute up out of driver's way when truck is driven to and from job.

My Construction Photos > Concrete construction, residence construction: Cast in place reinforced concrete foundation continuous footing placed in built in place dimension wood lumber side forms. Foundation for basement or lower level garage of residence, cast in bottom of excavation. Note that the bottom of the concrete is below the level of the general excavation, which allows the foundation to rest on soil that was excavated carefully so as not to disturb the soil on which the foundation rests. Concrete would have been placed by direct chute from the readymix concete truck except possibly for that at the far distance that might have been placed with cart/wheelbarrow/crane-bucket. Horizontal steel reinforcing bars were placed in the forms before the concrete was placed and provide tension strength to the concrete. The steel bars protruding from the concrete are to tie the vertical foundation wall, either cast in place concrete or concrete block masonry, to the foundation footing. Arlington Street, Ann Arbor, October 2005.
