Abstract
A new and novel process for constructing longitudinal concrete members such as beams by providing a longitudinal sack like mold constructed from a pliable sheet or sheets having an open throat supported by an open rim frame in turn supported by a plurality of inverted "U" shaped supports spaced apart one from another while in a common straight alignment while the supports rest upon an equipment base. The concrete members being either removed from the sack like mold, or the member being a cast in place member with the mold acting as a casing or protective skin. The sack like mold being a hybrid sling because of being provided with a long under loop support on which the loop portion of the true sling rests.
