Plant equipment refers to the machinery and materials that help to enhance a manufacturing shop's productivity by providing in-house services and utilities. These can include elevators, HVAC systems, security equipment, recycling services, refrigeration units, office supplies, cleaning services, and safety gear. Many of these features are necessary for keeping a manufacturing plant operational, as they make the environment more tolerable for workers and increase the likelihood of efficient production. Being able to move quickly in a safe, comfortable, and clean workplace can make a big difference in project effectiveness.
