Deep Foundations
Kiewit’s deep foundation work includes drilled shafts, micropiles, auger cast piles and driven piles. We have the knowledge, experience and equipment that is required for this specialized work and we can offer cost-effective solutions for any type of project.
Drilled Shafts
Drilled shafts (also called caissons, drilled piers or bored piles) have proven to be a cost-effective, excellent performing, deep foundation system, that is utilized worldwide. Typically they are used for bridges and large structures, where large loads and lateral resistance are major factors.
Advantages
- Economics
- Minimizes pile cap needs
- Slightly less noise and reduced vibrations
- Easily adaptable to varying site conditions
- High axial and lateral loading capacity
Micropiles
Relatively small-diameter piles. Installed using rotary or rotary percussive drilling methods. Generally compromised of steel casing, inner steel core and high strength grout. including a load transfer mechanism. Can be rock socketed or pressure grouted.
Advantages
- Tight working conditions and low-overhead environments
- Slightly less noise and reduced vibrations
- Easily adaptable to varying site conditions
- High axial and lateral loading capacity
Other Deep Foundation Techniques
Kiewit performs many other deep foundation techniques, including auger cast piles, helical piles, pipe or H-piles, and many other geotechnical solutions designed to meet your project’s needs.
