Topping out

In building construction, topping out (sometimes referred to as topping off) is a builders' rite traditionally held when the last beam (or its equivalent) is placed at the top of a structure during its construction. Nowadays, the ceremony is often parlayed into a media event for public relations purposes.^[1] 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.

A Scandinavian tradition of hoisting a pine tree to the top of framed out buildings had a more functional purpose: when the pine needles fell off, the builders knew the wood frame below had cured/dried out so they could enclose the building.^[2]

The practice of "topping out" a new building can be traced to the ancient Scandinavian religious rite of placing a tree atop a new building to appease the tree-dwelling spirits displaced in its construction.^[3] The tradition also served a functional purpose: a pine tree was used, and after the needles had fallen off the tree, the builders knew the wood frame below had cured/dried out so they could enclose the building.^[4] Long an important component of timber frame building,^[5] it migrated initially to England and Northern Europe, thence to the Americas.

A tree or leafy branch is placed on the topmost wood or iron beam, often with flags and streamers tied to it. A toast is usually drunk and sometimes workers are treated to a meal. In masonry construction the rite celebrates the bedding of the last block or brick.^{[citation needed]}

In some cases a topping out event is held at an intermediate point, such as when the roof is dried-in, which means the roof can provide at least semi-permanent protection from the elements.^[6]

The practice remains common in the United Kingdom and assorted Commonwealth countries such as Australia^[7] and Canada,^[8] as well as Germany, Austria, Slovenia, Iceland, Chile, Czech Republic, Slovakia, Poland, Hungary and the Baltic States. In the United States the last beam of a skyscraper is often painted white and signed by all the workers involved.^[7] In New Zealand, completion of the roof to a water-proof state is celebrated through a "roof shout", where workers are treated to cake and beer.^[9]

The tradition of "pannenbier" (literally "(roof) tile beer" in Dutch) is popular in the Netherlands and Flanders, where a national, regional or city flag is hung once the highest point of a building is reached. It stays in place until the building's owner provides free beer to the workers, after which it is lowered.^[10] Since the workers are treated to free beer as long as the flag is raised, the workers are considered greedy if they fly the flag for more than a few days.^{[citation needed]}
