A method, apparatus, and system are described for a monolithic, pre-wired, pre-engineered, and pre-assembled integrated platform for a critical power supply and electrical distribution system that is scalable and modular. The skeletal framework of the integrated platform acts as an equipment support structure and includes an upper superstructure and a lower superstructure. Two or more cabinet enclosures are mounted onto the lower superstructure where their weight is supported by the skeletal framework. One or more National Electric Code approved (NEC-approved) electrical cable routing support systems are mounted onto the upper superstructure. The skeletal framework also includes one or more vertical columns that are connected between the upper superstructure and the lower superstructure. The skeletal framework and the cabinet enclosures are fabricated in place as a monolithic, pre-wired, pre-engineered, and pre-assembled integrated platform prior to being installed.
