12 CONSTRUCTION
The footings were used as the foundation for both the bridge and classroom structural beams and columns. Once the footing holes were completed, the setting and leveling of the sonotubes began. The bridge had fewer, smaller tubes and was the first to be set and poured; this was followed shortly by the classroom. For the entire project, over 400 bags of concrete were mixed and poured by hand, the majority of which went directly into the footings.
