New Madrid Levee Jack and Bore

The Frontier-Arrowhead Joint Venture, LLC, was awarded a Firm Fixed Price contract by the USACE Memphis district for a Federal levee pipe jack and bore project along the Mississippi River levee system in New Madrid, Missouri.

The project entailed the installation of a new culvert by boring and jacking methods including: excavation, backfill placement/compaction, clearing and grubbing, disposal of materials, rip rap, installation of a new 48” RCP carrier pipeline inside 56” steel casing, demolition and tie-in to an existing junction box, installation of new sluice gate, construction of a new walkway (access bridge), construction of a new concrete outlet structure, removal of the existing flap gate hardware, grouting of the existing culvert, fill placement at the outlet channel, establishment of turf, and environmental protection.

Perimeter sheet piling was installed as needed on the river side of the boring to cofferdam the boring outfall.
