Full Name
ICC-ES AC517 – Acceptance Criteria for Push Pier Foundation Systems
Scope
ICC-ES AC517 outlines the acceptance criteria for evaluating the performance and design of push pier foundation systems used to support structures. These systems are typically employed to underpin existing foundations or provide support for new construction.
The scope of AC517 covers several key aspects, including:
- Establishing allowable loads: defining the methodology for determining the safe load-carrying capacity of push pier systems based on geotechnical investigations, structural analysis, and testing.
- Deformation capacities: assessing the allowable deformation or settlement of the piers under various loading conditions to ensure the stability and serviceability of the supported structure.
- Installation methods: evaluating the installation procedures and equipment used to install push piers to ensure proper placement and performance.
- Material properties: verifying the material properties of the pier components, such as steel pipes and brackets, to meet specified strength and durability requirements.
- Corrosion protection: assessing the corrosion protection measures implemented for the piers to ensure their long-term performance in various soil conditions.
The evaluation process typically involves a comprehensive review of the engineering calculations, drawings, and supporting documentation submitted by the manufacturer. It may also include field testing of installed piers to validate the design assumptions and verify the performance under actual conditions.
