Primavera is only inhabited during summer, and has 11 buildings for housing a maximum of 18 people, a crew usually made up by a staff of 6 Argentine scientists, 4 invited foreign ones and 7 army personnel. Some of the base's critical facilities are the main house, dining room, heliport, infirmary, power plant, vehicle fleet, laboratory, workshop (mechanical, carpentry) and deposits. The heliport is only usable during summer. The main activities at the base are centered on area logistics; general maintenance of domestic buildings, neighboring shelters, and search and rescue capabilities; support for scientific activities, medical and meteorological expeditions, nearby bases, and ships and aircraft, both local and foreign.
