Method for building a frame structure prefabricated with electrical wiring, plumbing, and hvac system

A method for framing a building structure prefabricated with electrical wiring, plumbing, and HVAC system, each floor of the building structure has an electrical column, a plumbing column, an HVAC column, a plurality of electrical beams, a plurality of plumbing beams, and a plurality of HVAC beams, the electrical column, and the electrical beams are prefabricated with electric wires, and the plumbing column and the plumbing beams are prefabricated with water pipes, and the HVAC columns and the HVAC beams are prefabricated with ventilation spaces, the method comprising:

• designing interior functions of each floor within the building structure;
• determining the positions of the electrical column, the plumbing column, the HVAC column, the electrical beams, the plumbing beams, and the HVAC beams in the building structure based on the interior design of the previous step, and these positions also comply with a location selection principles;
• installing the electrical column, the plumbing column, the HVAC column, the electrical beams, the plumbing beams and the HVAC beams;
• and
• connecting the electrical wires on the electrical columns and the electrical beams, the water pipes on the plumbing column and the plumbing beams, and the ventilation spaces in the HVAC column and the HVAC beams;
• wherein, the location selection principles include the following conditions:
• a. the HVAC column shall be located at the center of each floor within the building structure;
• b. the electrical column and the plumbing column are located at positions closest to a location of the power input source and water source respectively;
• c. the position of the electrical column and the plumbing column will not be adjacent, and the number of beams between the electrical column and the plumbing column should not be less than 2.
