Query: In what year was a hydraulic facility established?
Context: As a result of the boom, large commercial buildings, coffee palaces, terrace housing and palatial mansions proliferated in the city. The establishment of a hydraulic facility in 1887 allowed for the local manufacture of elevators, resulting in the first construction of high-rise buildings; most notably the APA Building, amongst the world's tallest commercial buildings upon completion in 1889. This period also saw the expansion of a major radial rail-based transport network.
