Video: Topping Out Ceremony

The final beam was put into place on Wednesday, June 17, as part of a topping out ceremony for the MPLX building, the last of the new buildings included in Marathon Petroleum Corporation's headquarters expansion in Findlay, Ohio. Employees were given the opportunity to sign the beam before it was installed. The beam was placed in the uppermost portion of the building, which will house many of the building's utilities.

About the "Topping Out Ceremony"

A custom within the steel construction industry is a topping out ceremony, which is held when the final steel member (beam) is installed in a building.

According to Modern Steel Construction Magazine, a topping out ceremony is a signal that the uppermost steel beam is going into place and the structure has reached its height. As the final beam is raised, an evergreen tree or a flag, or both, are attached to it as it ascends. The evergreen symbolizes the job went up without a loss of life or that it's a good luck charm for occupants. The flag can signal a structure was built with federal funds, or as a symbol of patriotism and the American dream.
