Work from the current confirmed layout
Before pricing or starting clearing, grading, drainage, driveway, pad, staging, or utility-path work, identify the current dated site plan or other controlling input for that scope and who confirmed it. Ask how revisions are communicated and which work must pause when a boundary, home location, access, septic or well area, utility route, foundation input, erosion requirement, or inspection prerequisite changes. The contractor defines its written work; responsible authorities and retained professionals control their separate decisions.
