Which of the following is NOT a type of project?

Restructuring is not typically classified as a type of project in the context of project management for telecommunications or construction. In project management terminology, types of projects usually pertain to specific actions related to construction, system enhancements, or accommodates changes within existing infrastructures.

New builds refer to projects that involve constructing a brand new facility or telecom infrastructure from the ground up. Modifications and upgrades involve making changes to existing systems, technology, or structures to improve functionality or performance. Retrofit projects focus on adding new technology or features to existing systems, intending to bring them up to modern standards or improve efficiency.

Restructuring, on the other hand, implies a reorganization of processes, systems, or perhaps business strategies, rather than the physical or technical changes characteristic of the other project types. Therefore, it does not fit with the common categorization of projects encountered in the telecommunications context.
