TOWER FOUNDATION (OHTL)
Here is a major difference between the design of foundations for transmission lines compared to the design of foundations for most normal civil engineering structures.he selected foundation design for a particular tower must provide an economical, reliable support for the life of the line. The foundation must be compatible with the soil and must not lose strength with age.
In the past, it was often acceptable to ‘over-design’ foundations to allow for uncertainties in the soil characteristics. With the large sizes of foundations for EHV and UHV transmission it is obvious that significant economies can be made in producing foundation designs to exactly match the soil conditions.Increasingly, transmission lines are routed through areas of poor ground conditions, often for reasons of amenity. This results in the need for the use of special, generally larger, foundations.
We have the resources in professional staff and technology to apply to any challenge facing overhead transmission line foundation.
