IAPMO UES EC 027
Full Name
IAPMO UES EC 027 – Evaluation Criteria for Helical Foundations for Use under the International Residential Code
Scope
IAPMO EC 027 outlines the evaluation criteria for helical foundations for use under the International Residential Code (IRC). This standard, developed by the International Association of Plumbing and Mechanical Officials (IAPMO) Uniform Evaluation Service (UES), focuses on assessing the suitability and performance of helical foundations for residential construction.
The scope of EC 027 includes:
- Performance requirements: it defines the minimum performance standards for helical foundations, including axial and lateral load capacity, corrosion resistance, and durability, to ensure they meet the structural requirements of the IRC.
- Testing procedures: it outlines standardized testing methods to evaluate the performance of helical foundations under various loading conditions, such as compression, tension, and lateral loads.
- Material specifications: it specifies the acceptable materials and manufacturing processes for helical foundation components, such as helical piles, extensions, and brackets, to ensure their quality and consistency.
- Installation guidelines: it provides guidance on the proper installation of helical foundations, including soil conditions, spacing, and depth requirements, to ensure their optimal performance and compliance with the IRC.
Manufacturers of helical foundations can seek evaluation and listing by IAPMO UES based on EC 027 to demonstrate compliance and gain acceptance in the industry. Builders and engineers can also refer to EC 027 for guidance on using helical foundations in their residential projects.
