Microsoft and Amazon already showed Seahawks love today. Boeing impressed nearly everybody a day earlier with that special Seahawks-themed 747-8 jet.

Now, construction workers building Google’s new office in Kirkland are in on the 12th Man fun, too.

A giant Seahawks logo measuring 150-by-75 feet was hand-painted on the site of Google’s Kirkland campus expansion, which will be home to a new 180,000-square-foot development right in Microsoft’s backyard.

SRM Development construction workers came up with the idea to demonstrate their support for the Hawks, who face Denver in Sunday’s Super Bowl. One worker drew the logo by hand and then used a grid to paint the giant logo itself.

Google’s new building, originally announced in March, is slated for completion by the end of 2015. It will double the size of what is already the search giant’s third-largest engineering center in the country. Teams at the company’s existing Kirkland engineering center, next to the new construction site, work on projects including Google+, Cloud and Chrome. Google also has engineering operations on the other side of Lake Washington in Seattle’s Fremont neighborhood.

Here’s what the building will look like when completed:
