In an era of global responsiveness, there is a continuing need for agencies and organizations to set up temporary contingency bases (CB) of operations in foreign nations. Examples of such CBs include epidemic hospitals, refugee camps, natural disaster response headquarters, and temporary military installations. The decision whether to import all construction material, to build entirely of local materials, or to purchase a combination of imported and local materials is a strategic decision. The outcome of such a decision will affect construction costs, maintenance costs, security of the facility personnel, and the local sentiment towards the CB occupants. In order to streamline the process, planners often choose to acquire all material and equipment needed to construct CBs in their home nation and then ship it to the deployment site.
