Two case histories are presented which describe the site conditions, foundation design, construction, and performance of transmission towers supported on helix anchor foundations. Both sites are located in low lying marshes in Central New York. Access for site exploration and construction was limited. The foundation design was based on minimal information of soil properties and was modified in the field due to installation problems. A comparison of the foundation capacities based on an estimate from installation torque is made with capacities based on geotechnical parameters of the soil. Construction procedures in difficult terrain and resolution of problems encountered during construction are described.
