Material and Installation Information
Deadman Anchors
The deadman anchor is a foundation design used for guy towers along with a pad and pier or mat design for the tower’s base. Excavation, carpentry, concrete and reinforcing steel skills are required to provide a safe, as-designed installation.
Using the correct loading, a structural analysis of the tower must be provided with base reactions in order for an engineer to provide a foundation design. A geotechnical/soil report is normally required in order to obtain sealed design drawings for a building permit.
Although the specifications will provide you with the reinforcing steel sizes and placement, concrete PSI requirements and the foundation sizes, the excavation and formwork requirements are to be designed by the contractor. A few deadman anchor designs will have the anchor rod encased in concrete. Taller towers may require three sets of anchors. Cathodic protection may be required.
 The default pricing is a baseline of averages throughout the country for deadman anchors and a tower base foundation in normal soil within 120 miles of the contractor’s office. The total includes excavation, forming materials, reinforcing steel, 3000 PSI concrete and installation. The size of the foundation will influence the cubic yard pricing provided. Prices will vary based upon soil conditions, location and additional design requirements. Add concrete testing to your proposal. If your bid documents require you to provide a proposal using "normal soil" conditions, try to get the owner to provide soil borings with a report to ensure a competitive bid environment.
