EXCAVATION SHORING SYSTEMS & SUPPORT SERVICES

Also known as shoring, excavation support systems (ESSs) are designed to support the ground behind an excavation. The excavation support system may also be designed to resist groundwater pressure, building loads, construction traffic, roadways, railroads, and many other types of surcharge loads.

Excavation shoring may be used to temporarily support the excavation until a new structure is built. It can also be designed to permanently support the excavation. Permanent excavation shoring systems differ from temporary shoring in that many of the components in permanent shoring incorporate protection from long-term corrosion.

The best type of excavation shoring for a particular project depends on a number of factors including soil conditions, required stiffness, and whether or not a groundwater cut-off is required.

Excavation support systems provided by Schnabel include soldier piles and lagging, soil nailing, secant/tangent piles, deep soil mix walls, and sheet pile walls. Lateral support for the excavation support system is provided by tiebacks, soil nails, braces or by designing the vertical elements of the shoring to cantilever. Schnabel can design and install the shoring best suited for your project because we have experience in designing and constructing most of the methods currently used in the United States.

WE’RE CONTINUALLY FOCUSED ON PROTECTING OUR EMPLOYEES AND CLIENTS FROM ANY UNNECESSARY RISK.

Capitol Crossing

Schnabel designed and installed over 100,000 square feet of excavation support for the Capitol Crossing project in Washington, DC. This project required several innovative solutions from Schnabel including soldier piles, lagging, tiebacks, braces, underpinning, single auger soil mix (SASM) walls, micropiles, and tiebacks.

Project Fusion

Schnabel designed and installed a 57,000-square-foot temporary shoring system to support the construction of Norfolk Southern’s new two-tower corporate headquarters in Atlanta, Georgia.

The Capitol Crossing project was one of the most complicated excavation shoring jobs in Schnabel’s history. The use of stiff single auger soil mix SASM walls based on deflection-based design resulted in the successful performance of the support of excavation adjacent to some historic and modern structures.
