S.02On every sheet

What you get back

  1. 01Plan

    At a scale that fits the cave on one sheet, usually 1:500 or 1:1000, with a grid and true north.

  2. 02Elevation

    Projected or extended, your choice. Pitches with their measured depth, the sump level if there is one.

  3. 03Sections

    Wherever the passage changes shape, keyed to the plan with a letter.

  4. 04Title block

    Length, depth, grade, who surveyed it and when, the instruments used.

  5. 05Files

    PDF and SVG for printing, plus the reduced centreline as a Survex file for the next team.

  6. 06Closure report

    Every loop, its misclosure and where we think the error is, if one leg stands out.
