The construction of military buildings will take place over a period of time, depending on the size and complexity of the project. Some aspects of the construction contract on Altus AFB could take several months to finish, and larger facility construction projects could span several years. Before the construction process starts, planning, design approvals, environmental reviews, and safety inspections are all crucial aspects of the process. Contractors need to take care to coordinate with the military operations in order to prevent disruption of base operations. While military projects can be more time-consuming than typical commercial projects, they are designed to be durable, secure and meet federal building codes to ensure long-term functioning and usability.
