Note. In equation (1), a = weight of facility; L = distance from facility to site; and d = service radius of the facility. In equation (2), Dmax = maximum distance between commercial facility and site; and Di = distance between commercial facility and site. Construction adaptability potential and engineering stability refer to the incorporation of existing constructions (structures) into the residential area, park, scientific research and office campus, and business district constructions in terms of structure, space, physical life, and foundation stability. Several experts and scholars have comprehensively evaluated the adaptability and transformation potential of existing constructions (structures) for residential, park, office, commercial, and other purposes.
