CHANCE® helical tiebacks are a pre-engineered mechanical anchoring system for permanent and temporary shoring. The success of the helical anchor tieback system is based on decades of similar use of CHANCE anchors in the electric utility industry. Capacities up to 200,000 pounds per anchor are obtainable with this “instant” tieback shoring method. CHANCE tiebacks offer a fast, cost-effective and simple solution for any tieback project.
A bit more obtuse than my last article, but definitely something to think about are the broader impacts that helical piles can influence when expanding the focus from product-specific sustainable features to a broader capital-S Sustainable community perspective…
For buildings and structures, material selection, energy conservation methods and good water efficiency are important parts to consider when thinking of sustainability. However, thoughts about what could be considered a sustainable foundation are often overlooked (or don’t go much “deeper” than costs or what LEED points it can qualify for). Let's explore how CHANCE helical piles effect the environment, economy, and society to create a more holistic view of what it means to be sustainable.
Dry Tortugas National Park is home to historic Fort Jefferson which was constructed for the protection of valuable shipping lanes in the Gulf of Mexico and along the eastern seaboard. The small remote island, only accessible by boat or seaplane, is located 70 miles west of Key West in the Gulf of Mexico and is surrounded by waters, beautiful coral reefs, and protected marine life.
A key benefit of helical piles is the ability to install them in environmentally sensitive areas. CHANCE helical piles are precisely engineered to create minimal disturbance to the soil itself during installation with the pitch and placement of the helices precisely calculated. Helical piles can also be installed using limited access installation equipment eliminating the need for damaging access roads and large equipment required for other foundation types.
