Resection Method.
This method is used for establishing the instrument stations or after completing the traverse surveying the important object cannot be located due to difficulties & missed the station. PROCESS:-
- Select the two stations P & Q on the ground & measure the length PQ & plot to a scale pq on a suitable scale.
- Set the table at P , Centre, & level the table so that the point p is over the P.
- Place the alidade along pq, orient the table by turning the board until the signal at Q is bisected, & then clamp it.
- With the alidade touching at p sight the station R & draw a ray p to r.
- Shift the table at R. & make the center & level & sight the point P by back sighting & clamp the table.
- With the alidade centered on q, sight the station Q & draw a ray. The point of intersection of this ray & that previously drawn from p gives the reqd point r.

Here I am discussing about High humidity & rain. Actually, the compressive strength of concrete reduces with the high relative humidity which results in durability problem. Due to higher moisture in the surface of concrete results a growth of mold and bacteria.
