NOTE-1 : While classifying foundations of Wet, Partially submerged / Partially black cotton, Fully submerged / Black cotton foundations mentioned above, the worst conditions should be considered and not necessarily the conditions prevailing at the time of inspection. For instance there are areas where subsoil water raised when canal water is let out in the field raising subsoil water to a considerable degree. Similarly the effect of monsoon or when the nearby reservoirs are full should be considered and not the conditions prevailing in open season or summer when work is carried out normally.

NOTE-2 : For locations of cut point / angle towers, the classification of tower foundations shall be at next higher type for ensuring safety of the Transmission line, which is likely to be subjected to seasonal changes / climatic conditions from time to time. NOTE-3 : In case of highly collapsible & loose soils and river crossings, special design for foundations are to be made by Civil Engineering wing for adoption on case to case basis. NOTE-4 : All locations subjected to water logging, particularly in paddy fields, ponds, marshy areas etc., the chimney of all stubs are to be raised to 600 mm over the normal chimney being adopted in other cases. This shall be done after completion of erection of towers as a separate item for identified locations.

NOTE-1 : While classifying foundations of Wet, Partially submerged / Partially black cotton, Fully submerged / Black cotton foundations mentioned above, the worst conditions should be considered and not necessarily the conditions prevailing at the time of inspection. For instance there are areas where subsoil water raised when canal water is let out in the field raising subsoil water to a considerable degree. Similarly the effect of monsoon or when the nearby reservoirs are full should be considered and not the conditions prevailing in open season or summer when work is carried out normally.

NOTE-2 : For locations of cut point / angle towers, the classification of tower foundations shall be at next higher type for ensuring safety of the Transmission line which is likely to be subjected to seasonal changes / climatic conditions from time to time. NOTE-3 : In case of highly collapsible & loose soils and river crossings, special design for foundations are to be made by Civil Engineering wing for adoption on case to case basis. NOTE-4 : All locations subjected to water logging, particularly in paddy fields, ponds, marshy areas etc., the chimney of all stubs are to be raised to 600 mm over the normal chimney being adopted in other cases. This shall be done after completion of erection of towers as a separate item for identified locations.
