Full Name
ICC-ES AC336 – Acceptance Criteria for Bearing Pin Piers
Scope
ICC-ES AC336 outlines the acceptance criteria for bearing pin piers used as foundations for exterior porch decks, elevated walkways, and stairway construction.
The scope of AC336 includes:
- Materials: specifies the requirements for the materials used in the construction of the bearing pin piers, including the concrete head and the steel bearing pin, ensuring their strength and durability.
- Design and construction: details the design and construction requirements for the piers, including their dimensions, shape, and connection details, ensuring their structural integrity and stability.
- Load capacity: outlines the testing methods and acceptance criteria for evaluating the load-bearing capacity of the piers under various load conditions, including vertical, lateral, and uplift loads.
- Installation: provides guidelines for the proper installation of the bearing pin piers, including soil preparation, driving depth, and spacing, ensuring their effective performance as foundations.
- Durability: addresses the durability of the piers, ensuring they can withstand environmental exposure, soil conditions, and other factors that may affect their long-term performance.
The AC336 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their bearing pin piers comply with the applicable building codes and standards.
