Concrete Construction: reinforcing, forms, saw, shore, precast, erect

Concrete cast-in-place construction: Gang forms for cast-in-place (CIP) reinforced concrete deep foundation/basement walls. Gang forms are sets of large form panels attached and braced together and moved by crane from place to place to cast large sections of concrete. The vertical concrete wall at lower right was cast using the gang form in middle of photo, rotated 90 degrees. It has been lifted and rotated into its current position by the crane. It will probably be lifted and rotated to form the wall section to the immediate left of the one it recently placed. Another gang form is in place on the right wall against which the next wall section will be cast. Workers at right are finalizing the details of reinforcing steel in preparation for the form to be placed. Reinforcing steel is being erected for the far wall to follow the wall on the right. In photo center is JLG telescoping boom man lift. The orange “mushrooms” in extreme foreground are reinforcing rod caps to protect workers who might fall onto the ends of the vertical rods.
