In a large plant, who typically makes up the building-maintenance group?

The building-maintenance group in a large plant is generally comprised of skilled tradespeople such as electricians, mechanics, plumbers, carpenters, and painters. This diverse group brings together various expertise necessary for the day-to-day upkeep and repair of the facility. Each of these trades plays a crucial role; for instance, electricians handle electrical issues, plumbers manage water and drainage systems, and carpenters take care of structural and fixture repairs.

In contrast, the presence of engineers and consultants is typically more focused on design, planning, and operational efficiency, rather than direct maintenance. Supervisors and managers are involved in overseeing teams and operations but do not usually engage in the hands-on maintenance work themselves. Independent contractors provide specialized services but do not represent the primary, ongoing maintenance team found within a plant. The internal maintenance team is essential for ensuring that the facility remains operational and safe, making the skilled tradespeople the correct answer for this question.
