Planning focus
Use reliable survey/property information rather than assuming curbs, hedges or old fences mark the legal boundary.
Budget drivers
Survey work is a separate project cost that may be justified before a long fence is ordered.
Operations and lifecycle
Keep survey and as-built records for later property work.
Safety and project boundary
Boundary and easement questions are matters for qualified local survey/legal professionals.
Educational planning only. Actual construction, code compliance, regulated systems, hazardous materials and safety-critical work require qualified professionals and current local requirements.
