Final answer:
A mechanical or MEP floor plan shows the arrangement and location of plumbing and heating features in a building, designed by architects and followed by detailed mechanical scale drawings.
Step-by-step explanation:
The type of plan that shows the arrangement and location of plumbing and heating features in a building is referred to as a mechanical or MEP (Mechanical, Electrical, and Plumbing) floor plan. This plan is developed by architects and engineers during the more detailed and technical phase of the design process after initial sketches have been made.
mechanical floor plan includes the exact location of heating and cooling systems, plumbing lines, water heaters, HVAC units, and other related details, forming an essential part of the building's overall design. Architects often begin with quick sketches, but soon move on to create detailed mechanical scale drawings that clearly illustrate the size, shape, and location of all elements necessary for the plumbing and heating systems.
