The purpose of a lot grading plan is to shape land in order to direct surface runoff away from buildings and structures at a construction site. Grading must direct runoff toward a street or lane. Civil engineers develop lot grading plans at the outset of projects, directing the excavation, earth moving, and land grading. Builders grade all properties according to an approved lot grading plan. Municipality bylaws mandate grading plans.

  The decommissioning process in the oil and gas sector is necessary for containing remaining hydrocarbons, and to protect groundwater. Demolitions can take months to complete, especially if located off-shore. It involves dismantling entire rigs with lifts powered by gas or electricity. Much of the scrap metal is recycled. The entry of the well is prepared for decommissioning. Downhole equipment is removed, the wellbore is cleaned out, and holes are plugged.
