// Appendix Duration per Panel Installed

11 days to construct a floor (Where there are 8 work hours/day) = 88 work

hours per floor wing

(88 hours) / (152 Panels) = 34.73 minutes per panel – Installation

This value takes into account crane operation or hoisting material to

the proper bay.

Therefore:

It takes 34.73 minutes on average to complete one panel around the perimeter

of the building.

There are 130 panels of glazing.

There are 22 precast pieces.

It is assumed that 28 minutes is assigned for the precast panels. This allows

the left over 6.73 minutes of each of the concrete panels (or 148.06 minutes

total)

Each of the 130 glazing panels of the third floor facade then gain 1.13 minutes

of additional installation time, yielding a total installation time to be 35.86

minutes.
