Full Name
ICC-ES AC406 – Acceptance Criteria for Belled Segmented Pipe Foundation Systems and Devices
Scope
ICC-ES AC406 outlines the acceptance criteria for belled segmented pipe foundation systems and devices. These systems are used to support structures by transferring loads to deeper, more stable soil layers.
The scope of AC406 includes:
- Materials: it specifies the requirements for the materials used in the pipe segments, bell connections, and any additional components like base plates or reinforcement. This ensures the system’s durability and resistance to corrosion and other environmental factors.
- Design and construction: it details the design and construction requirements for the foundation systems, including the dimensions, tolerances, and connection details of the pipe segments and bells. This ensures the system’s structural integrity and load-bearing capacity.
- Installation: it provides guidelines for the proper installation of the foundation systems, including soil preparation, drilling methods, and connection procedures, to ensure their stability and performance.
- Load capacity: it outlines the testing methods and acceptance criteria for evaluating the load-bearing capacity of the foundation systems under various conditions, including axial compression, axial tension, and lateral loads.
- Quality control: it establishes a quality control program for manufacturers to ensure that the foundation systems consistently meet the requirements of the acceptance criteria, including inspections and testing procedures.
The AC406 acceptance criteria are used by manufacturers to obtain an evaluation report from ICC Evaluation Service (ICC-ES), which demonstrates that their foundation systems comply with the applicable building codes and standards. This evaluation report is essential for ensuring that the foundation systems are designed, installed, and used safely in construction projects.
