the core of Portside accommodates a complex array of lifts . Both owners have dedicated shuttle lifts which link their respective parking floors to their foyers , and the office floors are then serviced via six dedicated lifts each . Portside has a total of 22 lifts altogether , including a service lift and fireman ’ s lift .
Although both FirstRand and Old Mutual specified 2,700mm clear floor to ceiling heights on their respective floors as well as 800mm deep ceiling voids for service reticulation , FirstRand further stipulated that their portion of the building be fitted with 250mm deep raised access flooring for additional electrical and data reticulation , whilst the rentable floor plates of Old Mutual received only a cement screed finish . The effect of this is that the floor to floor height of the tower changes from 3,850mm to 4,050mm from the 20th floor upwards . The additional height is taken up in the spandrel panels of the curtain wall , between the floors . Interestingly , this is not perceptible in the external elevations .
