What's with the branch?

December 1, 2006 6:41 AM

Why does a building under construction have a leafy branch tacked to the peak of the first roof joist over the building entrance?

On the way to work each day, I pass a construction site. I've noticed that a leafy branch was tacked to the joist above the door. My husband says it is some tradition but he doesn't remember the meaning or where it started. Can you fill me in?

Ah! I finally remembered what my Dad used to call this. My Googling for tree, construction, etc. wasn't doing much good. It's called a "topping out" ceremony, and it's done on all sorts of buildings.

The term you are looking for is topping out (wikipedia).

OMG, I've been an architect for 20 years and I never knew about that! Or rather, I thought it was just construction crews bein' goofy...

That's how ancient rituals start. Someone's long-forgotten ancestor was just bein' goofy, but it filled a social and emotional need and people kept doing it.

Thanks for asking this - I just saw this on my brother's house-building blog and was curious to learn more.

Typically an entire evergreen tree is used at the uppermost member of the building or on the construction crane when the framing is complete. It is primarily used on larger steel framing construction projects.
