| Sl.No. | Synosis Points | |
| 1 | Transmission line towers and poles are subjected to large horizontal forces at the top, thereby causing overturning and/or uplifting of foundation. The design of foundations for such structures involves special problems and this standard has been prepared with a view to providing guidance to the designer. Often well foundations are used in river beds for which the concerned IRC standard may be referred. | |
| 2 | The provisions on necessary information to be provided for design and construction of foundations for transmission line towers and poles have been modified. | |
| 3 | Provisions on footings with and without under-cut have been modified. A 30° angle of cone assumption for determining soil resistance to uplift in case of footing has been specified for all soil types. | |
