Cast in Place Concrete Construction is widely used for the construction of parking garages, hospitals, and high rise condominium structures.  This type of construction utilizes shored forms to create columns, beams, joists and slabs.  Concrete provides its own fire rating which eliminates the need to construct other fire rated assemblies.  Concrete floor systems provide low vibration transmission due to sound and movement.
