PPT-Types of Errors in chain surveying

It is always very difficult practically to measure length accurately The permissibleerror with a steel tape is 1 in 2000 in a flat country and 1 in 3000 for a rough undulating country The error in chaining may happen in various ways Sometimes there may be mistakes or confusion in reading the tallies such as 30 and 70 There may be also omission of chain lengths due to miscounting or when chaining is interrupted by buildings canals etc The error may also be either cumulative or compensating Cumulative errors are these which may either go on increasing or decreasing when a chain is shorter or longer than its standard length When the chain is too short the measured length of the line is too great. * ELEMENTS OF CIVIL ENGINEERING – 110004. * B.E. 1. st.

Sometimes it will be observed that many obstructions like rivers, canals, ponds. thick jungles, ditches, buildings, etc. lie on the chain line. These obstacles can be avoided in chaining operation by applying some fundamental geometric rules. . . Youness R. Karodeh, B.Sc., Pharm.D., R.Ph. .. Assistant Dean, Associate Professor and .
