The complex is dominated by a number of underground laboratories, test areas (including an Anti-Mass Spectrometer), and administration offices, most of which contain very high-tech equipment, and even a rocket launch site. Chemical processing plants are also seen and as the facility is located within the desert water treatment plants are required to recycle waste water. The facility is self-sufficient, housing its own: ventilation, cold and hot water, central heating, sanitation, drainage, and power generation systems including a Hydro-Electric Dam and multiple types of electrical generators and reactors, some using nuclear technology.

The complex is also equipped with retinal scanners and alarms, as well as heavy blast doors that may shut down in case of fire, explosion or other event.
Security guards, carrying firearms and trained for emergencies, are present in all of the facility.
Black Mesa undertakes its various scientific researches in the facility, which is a very high-security complex, as each employee is required to undergo a series of rigorous security checks to access most areas. However the surface areas of Black Mesa feature more modern construction. Some areas are also described by characters such as Rosenberg as "old" or "abandoned" several areas of the complex are badly run-down despite the obvious fact that they are still in use. Several Half-Life texture files' names contain the word "fifties", suggesting the facility is as old as from the 1950s. The Black Mesa facility was apparently built over several decommissioned ICBM launching and testing silo complexes probably constructed during the 1950s, which was converted into a vast civilian institute for the research of almost every conceivable scientific discipline. 5.2.9 Biological Waste Processing PlantĪ fast food outlet seen by Barney Calhoun in the Black Mesa Transit System. 5.2.4 Area 3 Medium Security Facilities.
