Marcus works in construction and uses programs that allow him to model the building itself, as well as the electrical wiring, plumbing, and heating needs of the building. Which type of program would

be most helpful to Marcus?

Building Information Modeling (BIM) programs would be most helpful to Marcus. BIM programs allow for the creation of detailed 3D models of buildings and their components, including electrical, plumbing, and heating systems. This allows Marcus to plan and coordinate all aspects of the construction process more efficiently and accurately.
