Transmission line towers constitute about 28 to 42 percent of the cost of the transmission line. The increasing demand for electrical energy can be met more economically by developing different light-weight configurations of transmission line towers.

Foundation of any structure plays an important role in safety and satisfactory performance of the structure as it transmits mechanical loads of the electrical transmission system to earth. A transmission structure without having a sound and safe foundation, it cannot perform the functions for which it has been designed. The foundations in various types of soils have to be designed to suit the soil conditions of particular type.

In addition to foundations of normal towers, there are situations where considering techno-economical aspect for special towers required or river crossing which may be located either on the bank of the river or in the mind stream or both, pile foundation may be provided.

Upon completion of the course, the delegates should be able to:

·         Select the type of tower depending on antenna load, footprint, height needed and financial budget.

·         To have a base good quality foundation essential for a safe tower with long lift time

·         Know that working at high height does always imply danger.

·         Use good equipment and play safe.

·         Make sure that you have the time that you need. Stress will allow you to make mistakes which can be very costly.

·         Always keep in mind the risks of corrosion and prevent it as far as you can.

·         Plan for continuous inspections for corrosion and other defects.
