System and method for embedding substrate in concrete structure

A system for allowing components to attach to a pre-cast pre-stressed concrete structure, comprising:

• a first attachment part having a first body, the first body having a first concrete structure facing side and a first plurality of attachment members extending from the concrete structure facing side;
• and,
• a second attachment part having a second body, the second body having a second concrete structure facing side and a second plurality of attachment members extending from the concrete structure facing side, wherein the first and second attachment parts are composed of metal and the first and second bodies include a metal plate and the first and second plurality of attachment members including a plurality of tabs extending from the respective metal plate, wherein the first and second attachment parts are spaced apart forming a compressible junction therebetween, wherein the compressible junction is formed by a slip joint formed by adjacent ends of the first and second attachment parts, wherein the pre-cast, pre-stressed concrete structure is formed from uncured cement, at least of a portion of the first and second attachment members being embedded in the pre-cast, pre-stressed concrete structure and the first and second bodies being outside of the pre-cast, pre-stressed concrete structure.
