    1. 01

      Define the project scope

      Record country, receiving authority, purpose, work grade and contractual requirements.

    2. 02

    3. 03

      Document the review decision

      Tie observations, files and reports to the identified requirement. Record unknowns and issues before acceptance.

    Is every technical reference a binding survey code?

    No. “Survey specifications” and “survey codes” are common search terms, but document type, edition, responsible authority and contract determine applicability. Official sources, teaching guidance and project requirements are distinct; undocumented legal force is not implied.

    Where are the calculators and file templates?

    Each guide links to the appropriate existing tool and template. Begin with the reference and review, then continue to the calculation or working file.
