This historic structure in Des Moines was built over a creek that spans the whole building. The footings of the original building were too low and oftentimes during the winter, the creek would overflow and rise above the building foundation.
Because this was a salmon spawning creek and the fish had to be temporarily removed from the river, we only had 2 weeks before the salmon were due to arrive. We had to secure the foundation of the structure as we moved it completely over to one side as we installed the new foundation that was steel and 24 inch concrete pilings. Then had to move the structure back over to its new footings. Much of the interior and exterior foundation and floor level of the building had to be repaired. The creek now runs unobstructed underneath the Des Moines building and will remain that way permanently.
