Deep Foundations

Kiewit’s deep foundations work spans three main areas: drilled shafts, micropiles and miscellaneous pile methods. 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

Micropiles (also minipiles of pin piles) are a deep foundation system constructed using casing and threaded bar in a variety of sizes. Micropiles are typically used for small diameter shafts and work well in tight working conditions and low-overhead environments.

Micropiles

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.
