In order to evaluate the structural capacity of an existing self-support tower, one soil boring was obtained near the structure’s foundation. At the time of drilling, foundation information was not yet obtained, so drilling was performed to a depth of 50 feet through a variety of clays, silts, and weathered shale to avoid the need to revisit the site for additional drilling. Soil parameters determined from an analysis of the collected boring were used in conjunction with our non-destructive testing group’s foundation mapping services to determine the ultimate bearing capacity and ultimate skin friction values for the structural engineer.
In order to evaluate the structural capacity of an existing self-support tower, one soil boring was obtained near the structure’s foundation. Due to snowy and difficult conditions at the site, an all-terrain track rig was used for access and to minimize impact on the site’s subgrade. This was a high-risk location due to an extensive network of underground utilities, so careful planning and coordination was performed between FDH, the driller, the client, and the landowner to ensure that the work could be performed safely and that all parties involved were satisfied with the results.
Lares Norte Tower
In order to evaluate the structural capacity of an existing self-support tower, one soil boring was obtained near the structure’s foundation. Due to the site’s remote location and poor road conditions, a dozer was first used to level and clear a path for the drill rig. Since the site was located internationally, FDH coordinated with the driller, customs, and receiving lab in order to ensure on time completion.
Haney Mountain Tower
In order to evaluate the structural capacity of an existing monopole tower foundation with guyed rock anchors, one soil boring was obtained and analyzed to evaluate various parameters of the soil profile. The site, located at the peak of Haney Mountain, required rock coring in order to penetrate volcanic sandstone. The soil and rock parameters obtained from the samples allowed FDH to accurately analyze the base foundation and guyed rock anchors.
In order to provide a full geotechnical profile of the subgrade soils for a proposed 83-bed assisted living facility, storage building, parking lot and realigned sanitary sewer, 31 borings were performed on 53,000 square feet of farmland and wooded terrain. The borings were performed to depths ranging from 5 to 25 feet. Additional research and laboratory testing was completed in order for this project to meet strict Federal HUD Design standards.
