As-Built Lot Grading Certification
Final grading certification after construction confirming the lot was graded per the approved plan, often needed for a certificate of occupancy.
What the work involves
Many jurisdictions require an engineer or surveyor to verify, after construction, that finished grades, swales and drainage match the approved grading plan before a certificate of occupancy or bond release. The professional surveys the as-built grades and issues a certification or as-built plan, noting any corrections needed.
