Supply Contract for Articulated Concrete Mattress

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 mass producing articulated concrete mattress (ACM) squares to government specifications within specific tolerances. ACM can be cast at government provided fields along the Mississippi River, or cast elsewhere and transported to those sites. Squares cast will be identical with minimal tolerance and have 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 Mississippi River. Casting

ACM has historically been provided via manual labor, and cast outdoors as weather permits.

Articulated Concrete Mattress:

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 3inches) that is used as an assembly system for interconnecting the 16 concrete blocks. A mix design is used to acquire 3000psi 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 forms are then placed over the wire mesh, the wire mesh drawn up into the notches in the sides and cross pieces of the forms, and cross rods driven. The central location of the wire mesh in the form is very important. The mat surface is consequently roughened to provide indentations of approximately 1/4 inch in depth and 1/8 inch width.

Currently, concrete is compacted to the depth of a government furnished form by the use of vibrators. The concrete is properly consolidated with no rock pockets, excessive voids or honeycombs visible on the mat surface.

The concrete is struck flush with the top of the forms and given a uniform surface finish and uniform thickness. Any squares not meeting government furnished specifications are rejected.

Requirements:

The Contractor shall cast ACM using coarse and fine aggregate, Portland cement, fly ash, air-entraining admixtures, and calcium chloride to produce articulated concrete squares, to government specifications. These units can be cast at government owned fields or other locations and delivered to the prescribed area. Squares of mattress shall be provided in stacks of 13 that are neatly aligned vertically and by rows. Squares cast will be identical with minimal tolerance and have compressive design strength of 3,000 psi at 28 days. Steam curing, automation, year around casting and other technologies for concrete preparation should be considered, while the overall design and specifications of the mattress will remain the same.

Interested firms should submit a capabilities package to include the following: The prime firm and/or its subcontractor(s) (hereinafter referred to collectively as “firm”) shall have relevant experience in mass production of casting concrete products. The firm shall demonstrate experience using pre cast concrete. This experience must have been performed within the last five years.
