7.11 Recording measurements for earth levelling work
7.11.1 Level Books
In case of levelling operations and earthwork, measurements are required to be recorded in Level
Books in addition to Measurement Books. The Level Books should be numbered, accounted for and
handled like Measurement Books.
7.11.2 Preparatory works
Before starting the earth work, the following steps should be taken:
(1) Original ground levels should be recorded in the Level Book in the presence of the contractor or
his authorised representative, and should be signed by him and the Departmental Officer who
records the levels. All the local mounds and depressions should be indicated clearly in the drawing
and the field Level Book, and should be checked by the Assistant engineer/Executive Engineer
before the levelling work is started.
(2) A suitable baseline should be fixed with permanent masonry pillars at distances not exceeding
150 metres to provide a permanent reference line for facilitating check work. The base line(s)
should be entered in the Level Book with co-ordinates. These baselines should be maintained till
the final payment for the work has been made.
