The load must be properly attached using a rigging system. There will definitely be a couple questions on the PE exam about lifting and rigging so make sure to do multiple practice questions.
Excavation and embankment (cut and fill)
www.learncivilengineering.comExcavation and embankment (cut and fill) Excavation = the removal of soil or rock from its natural location. Embankment = the placement and compaction of layers of earth or rock to form a roadbed of the planned shape, density, and profile grade. Various sections of a roadway design will require bringing in earth.
