The 33-level Memorial Hermann Tower (POB V) was partially occupied when Hurricane Ike hit the Houston area. Levels one thru 27 are comprised of precast concrete panels, glazed aluminum curtain wall, punched windows and a built up roof. Levels 28 thru 33 utilize a custom curtain wall system to create a very contemporary combination of angles resembling a crown topped off with a built up roof. The facility was partially occupied while other floors were being built when hurricane Ike hit in September 2008.
