The
data for the Road Sections shall be entered along the length of
the Road at various chainages. Usually the chainage value is used
in multiples of 5 mts. Or 10 mts. The quantities are calculated
between each two chainages, by taking the average of the area of
cross sections.
Following
levels are entered at each chainage, on both Left and Right sides
: Original Ground levels (OGL): The top levels of the original ground
profile. Progress Levels (PRL): The levels at various stages, as
the work progresses. Formation Levels (FNL):The top most level at
the centre of the Road. Rock Top Levels (RTL): If the rock is encountered
during excavation. Foundation Level (FDN): In case of Black Cotton
Soil, the level of good soil.
