The courageous actions of the pilots and flight crew were credited for saving the lives of all on board. But it was a physical force that kept the airplane afloat — a force known as buoyancy. For those in the underground utility business, however, it can be a pain if it is not accounted for in the design. Buoyancy is defined as the tendency of a fluid to exert a supporting upward force on a body placed in a fluid. The fluid can be a liquid, as in the case of a boat floating on a lake, or the fluid can be a gas, as in a helium-filled balloon floating in the atmosphere.

TorcSill was approached by a petrochemical plant owner to provide a value engineered foundation design and installation solution for a PVC Dryer to reduce the construction footprint while delivering verifiable load-bearing capacities required for a plant expansion. While value-engineering the appropriate helical alternative design for this Project, TorcSill had to account for a stringent maximum installation depth of 40 feet in very poor soil conditions while coordinating the construction amid a congested work site buzzing with various construction contractors and equipment. The first step for TorcSill's Engineering TEAM was to work closely with the facility's Engineer of Record to evaluate the foundation loads and geotechnical information. From here, TorcSill was able to determine the most efficient pile diameter and helical plate design to deliver appropriate axial, lateral and overturning performance within a maximum installation depth. Upon completion of engineering and load testing specifications, TorcSill's Construction Services TEAM mobilized to performed site-specific load tests, ultimately verifying the pile design, which consisted of 6 inch helical plates.
The Creators of Linkerd. See how. Without the observability that Linkerd gave us, it would have been difficult, if not impossible, to find the source of the problem. With a small team, we are managing about 2, sidecar proxies.
