As available tower space becomes more limited, it becomes imperative to tower owners and carriers to make the most of the existing space that is available. Oftentimes, this involves performing a structural analysis of the tower to determine its load carrying capacity and ability to support additional antenna structures. The existing foundation must be evaluated as part of this structural analysis.
What happens when the original foundation plans, geotechnical report, or as-built plans are not available? At this point it becomes necessary to perform an investigation to determine the subsurface conditions at the site and foundation type and dimensions. G2 has performed hundreds of such investigations across the United States for numerous clients including Semaan Engineering, Fullerton Engineering, Terra Consulting Group, W-T Communication Group, and all the major telecommunication tower owners and carriers.
G2 has the ability and network of drillers across the country to perform geotechnical investigations almost anywhere. Typically, our foundation investigations utilize low-strain pile integrity test methods to evaluate drilled piers. We also utilize excavation methods, as necessary, to determine foundation information. Our past investigations have also included evaluation of guyed anchor bars for corrosion below grade.
We also maintain a database of the thousands of tower sites we have worked on over the past 20 years and may be able to locate previous geotechnical reports or foundation designs, potentially saving a substantial amount of time and money required for new investigations.
