Facilities maintenance lies at the heart of museum work. The grounds and the buildings shape the visitor’s first impression upon arrival. Accessibility affects the ways in which visitors enter and navigate the space. Vigilant pest management ensures the integrity of both the building and the collection inside of it. Museum security protects whatever the building might hold – objects, documents, books, computers, etc. Managing and updating the facilities themselves and the techniques to maintain them are crucial to creating a clean, welcoming, and secure environment for visitors and museum staff alike.
