Anchors and Micropiles

Kiewit Foundations’ small diameter drilling fleet is comprised of Comacchio and Casagrande hydraulic, dual rotary crawler drills of varying operating capacities and weights. These drills can operate both in low- or high-headroom configurations. Our rotary and/or percussive methodologies and tools allow for open-hole, cased hole, over-burden or rock drilling, suitable for installation of bar or strand anchors, high-capacity dam anchors, tie-downs, and micro (and macro) piles up to 18-in diameter. Kiewit Foundations makes extensive use of spoil diverters mounted to these drills, maintaining the highest standards of site cleanliness.

Piling and Cranes

Kiewit’s crane and lift capabilities, both in numbers and capacities, are unmatched in the construction industry. Kiewit Foundations draws on this fleet for varying foundation project needs as they arise, where they arise. From smaller support cranes for anchor jobs, to custom equipped duty-cycle cranes for deep vibro-replacement work, to cranes supporting oscillators or leads for shaft and piling work, Kiewit Foundations has the right crane, fitted with the optimal attachments.
