BARCUS AND SONS, INC. PROJECT PROFILE: 108-10 in. diameter AugerPiles installed to an approximate depth of 32 ft. Piles were installed through Stiff Clayey Fill and Medium-Dense Sands to Decomposed Shale. Piles were drilled to a refusal criteria of 1 ft. / 3 min. Piles were installed using a Barcus Mantis AugerPile rig which is large enough to install piles 25 to 50 ft. long outdoors. The Mantis is also ideal for indoor and low overhead installations. On top of being extremely versatile, the Mantis is also very economical to mobilize. The existing structure is supported on H-Piles. The AugerPiles were furnished and installed for less than the material price of the H-Piles. Design loads were under 40 tons which eliminated the need for a load test. AugerPiles were selected for minimal vibration, limited noise, and economy.
