Commercial & Industrial New Construction

New Construction Foundation Systems

 

Civil Construction Applications: Residential, Commercial and Industrial

CHANCE® Helical Foundation Systems for new construction are designed, tested, and proven for applications in expansive soils, high water tables, fill areas, and other areas where unstable soils require piling.

On reinforced footing or stem walls, the new construction Helical Pile Foundation Systems anchors are usually placed every 5 to 10 feet depending upon the load of the structure and the bearing strength of the soil.

A two-man crew with a skid loader can place over 30 helical piles ready for loading in less than one day. Helical Piles rated by the building codes for working loads of 10 to 20 tons are typical. For new deep foundations, CHANCE® helical pile systems are installed at intervals between the footing forms and tie into the rebar gridwork prior to pouring concrete. The steel piles are extended to depths attaining the required installing torque correlated to the required load bearing capacity.

The CHANCE® Helical Pile Foundation System Features

  • Reach competent soil below active zone
  • Predictable via torque-to-capacity correlation
  • No excavation or spoils to remove
  • Loads may be immediately applied
  • Installs in limited access
  • Installs in any weather condition

The Shape of Stability

Helical Piers for New Construction

The true helix geometry of each steel bearing plate minimizes soil disturbance during the vibration-free installation. Approved by, CCMC and ICC-ES, CHANCE® helical piles have become the deep foundation system of choice for architects, builders, contractors, engineers and geotechnical firms.

 

New Construction with CHANCE Helical PulldownsCHANCE® Helical Piles have 1-1 ⁄2″ to 2-1⁄ ⁄ 4″ solid square shafts or 3-1 ⁄2″ pipe shafts with helical plates 8″ to 14″ in diameter. For more details, see Technical Design Manual – 3rd Edition.
