Practically all new construction of significant size or requiring accurate placement starts with the setting of stakes by a land surveyor. These stakes can control the location of fences, structures, streets or any other new construction. Using the maps prepared by another professional such as a geologist, architect, or engineer the necessary points are staked and a map and "cut-sheet" delivered to the contractor showing the points and their relation to the proposed construction. In some cases a boundary survey will need to be performed before stakes can be set to determine the location of existing boundaries, setbacks, and easements.
