ICC-ES AC358
Full Name
ICC-ES AC358 – Acceptance Criteria for Helical Pile Systems and Devices
Scope
ICC-ES AC358 establishes the requirements for helical pile systems and devices to be recognized in an ICC-ES evaluation report under the International Building Code (IBC).
The scope of AC358 includes:
- Materials: specifies acceptable materials for helical piles, shafts, and helical plates, including steel grades and coatings.
- Design and construction: outlines design and installation requirements for helical pile systems and devices, covering aspects like shaft dimensions, helix configurations, and connection details.
- Performance: defines performance criteria for helical piles, including axial compression capacity, axial tension capacity, and lateral load capacity.
- Testing: details testing procedures for evaluating helical pile performance, such as compression load tests, tension load tests, and lateral load tests.
- Soil interaction: addresses the interaction between helical piles and soil, including methods for determining soil embedment and soil capacity.
By outlining these requirements, AC358 ensures that helical pile systems and devices meet the necessary safety and performance standards for use in foundation applications. It provides confidence to building officials, engineers, and contractors that these products comply with building codes and are suitable for their intended use.
