IQ Contracting installed 6 large retaining walls for 3 stream crossings. The foundations were installed frequently in rock and were very large, sometimes over 6’ thick and up to 30’ wide. The walls themselves ranged from approximately 6’ tall to over 30’ tall and had pipes as much as 11’ in diameter intersecting to accommodate the stream flows. IQ handled all excavation, all pump around of streams, managed the inspections, and built all the walls for a turnkey project to the client.
