“Foundations” of sustainability

Posted by Brent Adams on Sep 14, 2021 2:50:42 PM

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.

Helical Anchors: The Superior Choice for Mooring Applications

Posted by Stephen Scott, EIT on Sep 7, 2021 10:39:00 AM

On land, piling and anchoring solution are abundant and helical anchors have always been known to be cost-effective, versatile, and easy to install. Offshore, however; helical anchors stand alone as the superior choice for mooring applications. First used in the marine environment to secure oil pipelines to the ocean floor, helical anchor technology has been proven to be a successful and environmentally sensitive alternative to traditional mushroom, deadweight, and pile anchors for boat owners, harbormasters, and marine construction and civil engineering firms.

Objecting to Obstructions in Deep Foundation Installation

Posted by EBS Geostructural on Jul 15, 2021 8:45:00 AM

Obstructions can be difficult, because you often do not know they are there until you begin to install a deep foundation. Helical piles cannot install through obstructions; however, here we highlight the different options you have for dealing with obstructions while installing helical piles. One of the benefits of helical piles is that you do not have to abandon the pile. In most cases, it can be removed and reinstalled (unlike other deep foundation options).

Helical Pile Applications for the Oil & Gas Industry

Posted by Fernanda Osborne on Jul 7, 2021 12:33:00 PM

Helical piles are an excellent foundation solution for the oil and gas industry, both in congested and remote areas. They are easy to install and can be uninstalled (if necessary) and reused at another location. They are displacement piles, so they produce no spoils, no time is lost waiting for concrete to cure before loading, and they are installed with minimal environmental impact. For oil and gas applications, helical piles can be the most suitable foundation solution in the segment.

Overcoming Helical Pile Design Engineering Challenges

Posted by Ben Jennings on May 24, 2021 9:32:00 AM

Have you ever needed to estimate the axial capacity of a helical pile? You could calculate helix bearing and shaft friction by hand, but there is a better method. Use HeliCAP® v3.0 Helical Capacity Design Software! HeliCAP is software that estimates the axial capacity of helical piles, is free to use, and accessible from any computer, smartphone, or tablet with an internet connection and a web browser. A desktop or laptop computer with the Google Chrome web browser is recommended for best results.

Helical Pile Shaft Optimization

Posted by Gary L. Seider, PE on Apr 8, 2021 9:45:00 AM

The shaft type/size of a helical pile is critical to both the axial and lateral capacity – especially for compression in soft/loose overburden soils where lateral stability of the shaft must be considered.  The following is a brief summary of the 4 different shaft types commonly used for helical piles and their relative advantages and disadvantages based on site conditions and application.  It is very important to understand that helical pile installation must be considered in the design process.

Helical Piles vs Concrete Drilled Shafts (Caissons)

Posted by Shawn Downey on Mar 2, 2021 4:39:03 PM

There are several solutions engineers and contractors can choose from when a deep foundation is required. With a deep foundation the structure’s load is transmitted to soils that are deeper in the ground. A deep foundation is used when a shallow foundation is not possible, not practical, or will not carry the load. Examples are weak, unstable, or expansive surface soils. Two popular options for deep foundations are helical piles and drilled shafts, also known as drilled piers or caissons.

Helical Piles: New Technology or Just Back In Style?

Posted by Dave Bruce on Jan 28, 2021 7:00:00 AM

The first question we often get is, “are helical piles a new technology?”. Though they are growing each year in use and popularity, many Geotechnical and Structural Engineers are often unfamiliar with the technology. Complicating the matter is that, in many cases, students who will be our future engineers know very little about helical piles and their history. The truth is that helical piles [a.k.a. screws, screw piles, helical piers, helicals] appeared on the scene in the early 1800s. Alexander Mitchell (1780-1868) applied the use of screw piles in 1836 for moorings and, in 1838, for a lighthouse foundation. To put things into perspective, screw piles preceded the advent of Portland Cement [1850’s] and first use of a gasoline-powered automobile [1886]. According to some historians, screw piles were the major foundation technology of the 19th century.
