ICC-ES AC509 – Acceptance Criteria for 3D Automated Construction Technology for 3D Concrete Walls


The purpose of this criteria is to establish the basis for recognition of 3D automated construction technology for use with proprietary 3D concrete for the construction of 3D concrete walls in ICC-ES evaluation reports under the the International Building Code and the International Residential Code.

This criteria applies to 3D automated construction technology and 3D concrete used to construct interior and exterior 3D concrete walls, with or without structural steel reinforcing, used as bearing walls, non-load bearing walls, and shearwalls, in one-story or multi-story structures. The walls are to be constructed by printing 3D concrete in layers to create two outer face shells, then placing a proprietary concrete core between the shells to form a solid wall.

This criteria contains provisions for the evaluation of the material and durability properties of proprietary 3D concrete, and the evaluation of structural performance of 3D concrete walls and proprietary wall-to-floor connections, designed in accordance with the applicable sections of the referenced codes.
