King Dome Demolition Containment
In 1994 Seattle Tarp Company was asked to help solve a large weather protection problem for the Kingdome re-roof project (The Kingdome was a domed stadium located in Seattle with a capacity of 75,000). With the start date of late August and a projected schedule that would have the project lasting until early spring several glaring problems came to the top. The first thing was the fact that the 7 layer roofing system that was being applied is very weather sensitive. There could be no moisture present during the application of the roof system. The Seattle area’s wet season being October through the beginning of summer was the main concern.
In addition to this, the fact that the roof area being 9 acres presented the other glaring challenge. Making this even more improbable was the fact that there was still many Seattle Mariners games to be played, dozens of events from Christmas bazaars to monster truck shows, In addition to a complete NFL season for the Seahawks, all the while the roof having the repairs being performed. Although the project got off to a slow start, by the time the rains came STC had provided 11 air-inflated tents that were secured to the outer ribs and moved from rib to rib as the project moved to completion.
With a support crew of Iron workers, a gifted crane operator and of course a large “Horse crane” STC flew the tents and secured them into position all the while maintaining them and improving the performance as they went. Using the already heated air from the Kingdome interior the tents were pumped to 1-1/2 pounds of static pressure allowing the tents to maintain strength and integrity through windstorms that produced 60 mph winds. The tents performed through the entire project resisting snow, sleet, and of course lots and lots of rain.
