Defense housing, Erie, Pennsylvania. This excavator can dig foundation for two four-unit buildings in eight hours, an operation that would require several days by hand. Foundations go down five feet for cement support blocks. The ground between the foundation blocks is later forked preparatory to receiving a cinder filling. Since there is no basement, the cinders afford a solid base for concrete flooring
