Based on the Route sketch of the proposed Road provided by the Client, relevant Road Survey will be carried out by using Total Station Survey Instrument covering the distance of the Road line, and capturing various Topo Featurs falling within the corridor of existing / proposed Road route.
The MSL Location and its value provided by the Client will be transferred to the starting point of the Road route, and arrive at the Levels that existed. Based on this value, the Spot Levels along the entire proposed Road Route will be taken by using the above instrument/Auto Level Survey Instrument and if required, beyond the side ends for a suitable width along the Road Route.
However, if MSL value is not available at the nearby location (though it is a must), an assumed bench mark value at 100m, or as the case maybe, will be taken at the Starting Point of the proposed Road Route and fix the value on any Permanent Structure. Based on this value, temporary Bench Marks (TBM) along the alignment route of the Proposed Road route will be established and fix its respective value.
