The FMB is a compilation of the measurements made in a particular field. The book contains information on the location, type, and extent of the measures and the dates when they were taken. The purpose of the FMB is to provide a record of the measurements for future reference and analysis. Scale 1:1000 or 1:2000 is the individual survey number sketches that are maintained. It is divided into subdivisions. The owner owns the subdivisions. 

The FMB is typically used by engineers and other professionals who need to know the precise dimensions of a field to make calculations or carry out different tasks. It is also often used by surveyors, who use the book to verify the accuracy of their measurements. 

The FMB can be a valuable tool for anyone who needs to measure a field accurately. It can help to ensure that the measurements are made correctly and that the results are reliable

Types of Field Sketches under Field Measurement Book Sketch 

There are three types of field sketches that can be made in a field measurement book: 

Profile sketches, plan drawings, and sectional elevation sketches. 

Prfile sketches show the ground profile along a line, while plan sketches show the layout of an area. Sectional elevation sketches show how the ground changes in elevation along a line. All three types of graphics can be helpful for different purposes.

  • Profile sketches are typically used to show the ground profile along a proposed route for a pipeline or other linear feature. 
  • Plan sketches can be used to show the layout of an area, such as the location of buildings, roads, and other features. 
  • Sectional elevation sketches often show how the ground changes along a line, such as a proposed pipeline route. 

When making field sketches, it is essential to use symbols consistent with those used on engineering drawings. This will ensure that others can easily interpret the graphics.

5 Purpose of Field Measurement Book Sketches/Field Book

Engineers and surveyors use a field book to record their measurements and observations while working in the field. The book typically contains blank pages with lines and grid patterns that allow the user to draw neat and accurate sketches.

  • The F-line represents the property lines of the land.
  •  The subdivision lines divide the surveyed area into smaller sections.
  • The ladder helps to identify the elevations of points within the surveyed area.
  • The extension lines are used to connect points on the sketch. 
  • In addition, the sketch also includes neighbouring field survey numbers, which can be used to cross-reference other surveys of the area.
