Applications

Communication Towers

The location of a communications tower facility usually comes down to two factors; where can the best signal strength be obtained for the area and what available land is there? The availability of land is usually the predominent factor in very urbanised areas and frequently ends up being a very confined, leased space.  Space is at a premium and square metre area is often limited.

Screwpiles offer designers the ability to limit the m² area by catering for the large overturning moments exerted on the foundations by wind loads on the tower.  The piling layout configuration is installed inside the perimeter of the mass foundation and may consist of 3-4-6-8-12 piles, of which some may be installed at raked angles to reduce moment & shear loads. The screwpiles will act in both tension and compression, subject to wind behaviour and cyclic loads.  Wherever possible, our engineers encourage the lateral loads, or shear forces exerted on the foundations to be transferred into the ground by utilisation of mass foundations, sides and the passive resistance of the soil to those surfaces.  Whilst screwpiles can generate substantial compressive and tension load resistance economically, they do not cater for substantial shear loads.  These loads must be catered for by other means, such as the passive resistance of footings and by concrete filling and raking the angle of the screwpiles.

Communication tower signals are very sensitive to sway and rotational movement of the structure, therefore the foundations must be securely fastened to the ground.  At locations where the ground conditions are weak or reactive, a comprehensive geotechnical report should be conducted to enable designers to provide the most economical solution.
