Topping out

Common card · No. 250178

In building construction, topping out (also referred to as topping off or roofing ceremony) is a builders' rite traditionally held when the last beam (or its equivalent) is placed at the top of a structure during its construction. From the late twentieth century, the ceremony has often been parlayed into a media event for public relations purposes. It has since come to mean more generally finishing the structure of the building, whether there is a ceremony or not. It is also commonly used to determine the amount of wind on the top of the structure.
