New tower foundation designs seek to customise structures to suit the local terrain and reduce the time required for construction. The foundation is the name given to the system which transfers to the ground the various steady state (dead) and variable (live) loads developed by the transmission tower and conductors. Now because in electrical transmission towers, the footing experience extensive corrosion which is a big challenge. A grillage foundation could be used to support a communications tower when it is guyed;
A grillage foundation could be used to support a communications tower when it is guyed; The grillage bases were constructed with steel angles with a length of 5.5 feet and width of 3.7 feet. The corrosion of tower/ stub or grillage steelwork including guy foundation anchor rods and helical screw anchor shafts occurs in a similar manner to that described.
