My Construction Photos > Caterpillar IT38G integrated tool carrier, fitted with side dump bucket, backfills trench under direction of worker with shovel. Mott Childrens Hospital, University of Michigan, Ann Arbor, Michigan. 2007.

My Construction Photos > Earthmoving construction: Bobcat 334 rubber-track hydraulic compact backhoe/ excavator with backfill blade. Young operator measures it out in rotunda at annual Science of Big Machines exhibit by the northern Ohio construction industry at COSI, the Center for Science and Industry, Toledo, Ohio, June 2006.

My Construction Photos > Earthwork, steel, concrete construction: Basement area has WF steel soldier beam, timber breastboard, tie back temporary retaining wall in left center. Bundles of resteel sit at grade level behind retaining wall, and two horizontal cables provide excavation edge fall protection. Right center bottom to top cast-in-place (CIP) reinforced concrete foundation piers sitting on CIP spread footings below and support base plates for H-section columns for superstructure. Protruding from piers are rebars, in circular pattern in piers, and 4 anchor bolts for column base plates. The rebars will be cut off before base plates and columns are set. heavy copper wire also protrudes from top of piers that is also attached to an electric ground plate in soil at bottom of footing. The cable will be attached/ spliced to metal above to provide an electic ground for building. Resteel extends above CIP foundation wall at bottom and upper right to provide reinforcing continuity at joint with future wall above and CIP slab to right. Backfill at bottom of excavation is sand, and additional granular material at top rear will later provide vertical support for CIP slab. Pink polystyrene sheets stacked in excavation will provide insulation when attached to exterior of foundation/ basement wall, as at mid-height far right. Cardiovascular Center, University of Michigan Hospital, Ann Arbor, 2004.

My Construction Photos > Soil moving, road construction: Worker pushes a gasoline driven vibratory soil compactor on a crushed gravel layer to provide base for street curb and sidewalk. Additional crushed gravel is in shovel of Caterpillar skeed steer loader on right. In foreground is excavation in which another worker is building a drain basin with concrete block and mortar. Huron Parkway, Ann Arbor, Michigan, 2005.

My Construction Photos > Soil construction, foundation construction: Nuclear gauge setup and setup tools, for measuring density of soil. Soil is fresh fill behind a retaining wall that has just been compacted by a manually operated vibratory soil compactor, and the technician is measuring soil density. On left side is geo-fabric to contain soil fines and water, for water to drain out at base of wall through flexible corrugated plastic soil tubing. Huron Parkway, Ann Arbor, 2005. (Note: Non-nuclear gauges have made nuclear gauges obsolete. See Electrical Density Gauge and Geogauge at www.humboldtmfg.com, which won the Nova Award for construction innovation.)

My Construction Photos > Soil, earth construction: Wacker WP 1550 manually operated walk-behind vibratory plate compactor compacting soil fill behind retaining wall. Geotech fabric covers back side of retaining wall. In distance is nuclear guage and technician that measures density of compacted soil. To right is unexcavated earth embankment. Fill will be placed up to top of retaining wall, compacted in lifts specified by design, probably 6, 8, or 12 inches. Huron Parkway, Ann Arbor, 2005.

My Construction Photos > Soil, earth construction: Caterpillar 325L crawler mounted hydraulic boom backhoe excavator places soil fill behind and against the back side of soldier beam supported precast concrete panel retaining wall. Soil is compacted in 6" to 12" lifts/ layers by vibratory plate compactor. Caterpillar 950F wheeled tractor front end loader at rear left maintains soil pile so backhoe can easily fill its shovel to place soil behind wall. In right front is roll of geofabric that is used as inside liner for retaining wall. Huron Parkway, Ann Arbor, Michigan, 2005. Fill will be placed up to top of retaining wall, compacted in lifts specified by design, probably 6, 8, or 12 inches. Huron Parkway, Ann Arbor, 2005.
