The Hyatt Grand Cypress Ballroom Expansion created multiple challenges for us to overcome. Since this was an expansion, the original building was still in operation with guests staying on site. This required our crews to keep noise at considerate levels and limited the hours in a day we were able to pour concrete. The site for the expansion was also extremely limited and not large enough for the crane to tilt certain panels. This required the middle portion of the slab to be left out so the crane could access those panels for erection. A foam-core model was used to better inform the contractor of the sequence of erections and coordination with bracing.
