The City of Grand Rapids and Kent County selected Granger Construction to oversee major HVAC, hydronic equipment and other upgrades at the Grand Rapids City Hall and Kent County Administration Building.

This campus is located on a raised concrete plaza in downtown Grand Rapids, with the City Hall occupying a 10-story structure and the County Administration Building occupying a 3-story structure.

The major equipment removal and replacement took place through the roof, using a crane situated on a busy downtown street between City Hall and the Devos Place.
