Hello All:
I’ve to review a proposal from a vendor to provide some radiator equipment on a roof at a height of 13 m from ground. The height of radiator fans is 7.5 m from roof.
So the total height of equipment is around 20.5 m.  The size of each radiator is 10.4m x 4.4m weighing 19tonne. Such 8 radiators has to be provided. What are the major factors to be considered when I evaluate such a proposal?.
Thanks in advance,
