Automated Mat Casting Plant Description SOURCES SOUGHT Automated Mat Casting at Richardson Landing, TN Introduction: This is a SOURCES SOUGHT announcement; a market survey for information only, to be used for planning purposes. THIS IS NOT A SOLICITATION FOR PROPOSALS AND NO CONTRACT WILL BE AWARDED FROM THIS ANNOUNCEMENT. The Government is seeking qualified, experienced sources capable of executing a design build contract to develop an automated casting plant at Richardson Landing to mass produce articulated concrete mattress (ACM) squares to government specifications within specific tolerances. Squares cast will be stored on the current casting field and have must have a compressive design strength of 3,000 psi at 28 days. Background: Annually, the United States Army Corps of Engineers (USACE) Mississippi Valley Division casts approximately 150,000 squares of ACM at 3 government furnished locations (see Figure 1). The ACM is used as revetment to maintain channel stability for the Lower Mississippi River. Casting ACM has historically been provided via manual labor and cast outdoors as weather permits. Articulated Concrete Mattress - Current Process: An articulated concrete mattress square consists of 16 individual concrete blocks (4 feet x 18 inches x 3 inches thick). They are currently cast in government furnished forms upon a proprietary wire mesh to form an articulated concrete mattress square (4 feet x 25 feet x 3 inches) that is used as an assembly system for interconnecting the 16 concrete blocks. A mix design is used to acquire 3,000 psi on a 28-day cylinder break. Squares of mattress are cast in stacks of 13 that are neatly aligned vertically and by rows (see Figure 2). One layer of specified paper is placed as a separation beneath the bottom square of each stack and between each successive layer of mattress. The current process requires the wire mesh to be placed on the paper with the cross wires (bracket wires) on top of the longitudinal wires. The...
