The Greater Orlando Aviation Authority (GOAA) installed manhole SS-04 and an 8-inch ductile iron (DI) sanitary sewer pile along Hanger Boulevard in Orlando. The manhole SS-04 settled several inches and the 8-inch DI experienced deflection approximately 10 feet north of manhole SS-04. The 8-inch DI was buried about 20 feet below the existing grade and the bottom of the manhole SS-04 about 20.5 feet below the existing grade. Both the DI pipe and manhole were set on a 4-foot rock bedding material.
