A method and apparatus are disclosed for use in conjunction with concrete construction that incorporates steel reinforcing bar formwork. In particular, the invention relates to a clamp that includes a plate having a plurality of gripping positions for clamping a first reinforcing bar against the plate and a recessed channel positioned on the plate between the gripping positions so that when a second reinforcing bar is aligned in the channel and the first reinforcing bar is clamped at the gripping position, the gripping positions will hold the first reinforcing bar and will also hold the first reinforcing bar in an overlying fashion against the second reinforcing bar in the channel. The present method includes constructing formwork from reinforcing bar for use in concrete construction, and in particular, includes the steps of assembling reinforcing bars into a desired arrangement, stabilizing the formwork by securing clamps to select intersections, and lifting the assembled formwork for incorporation into a building under construction.
