The size and suitability of such armories, camps, ranges, bases, buildings, structures and other facilities and the necessity for expenditures for all work to be done for all materials, articles and equipment to be furnished or installed and for all services to be performed pursuant to authority granted in subdivision one of this section shall be determined by the adjutant general.
