Booking a Level Run, step by step

Rise and fall method. The check is three equal differences.

  1. Book each readingBacksight, intermediate or foresight, one line per staff position.
  2. Work out rise or fallCompare each reading with the one immediately above it.
  3. Carry the reduced levelsAdd a rise or subtract a fall from the previous reduced level.
  4. Total the four columnsBacksights, foresights, rises and falls, each summed.
  5. Apply the checkΣBS − ΣFS = Σrise − Σfall = last RL − first RL.
  6. Close on a benchmarkCompare with the known level, then distribute the misclosure.

The check in numbers

  • ΣBS 4.215, ΣFS 3.100
  • Difference = +1.115
  • Σrise − Σfall = +1.115
  • Last RL − first RL = +1.115

Who is the Booking a Level Run poster for?
Booking a Level Run belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning surveying can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Booking a Level Run poster?
Reducing a field book, and proving the reduction before leaving site. A wall chart earns its place by being glanceable from where the work is happening, so Booking a Level Run belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Booking a Level Run?
Areas & Volumes, Bearings and Contours sit alongside Booking a Level Run in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Areas & VolumesBearingsContours
Is the Booking a Level Run poster free to download and print?
Yes. Booking a Level Run downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Booking a Level Run poster print at?
Booking a Level Run is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Booking a Level Run loses nothing.Printing guide
