As a leader in earth-retention solutions and advanced specialty foundations, Schnabel is your trusted provider of excavation shoring systems tailored for various environments.

Excavation shoring systems play a crucial role in stabilizing the walls of an excavation, ensuring that nearby structures, roads, and utilities remain intact and undisturbed.

Schnabel offers highly specialized excavation shoring systems (ESS) designed to meet the diverse subsurface conditions encountered across the United States.

With expertise as a top Geostructural Design & Construction contractor, Schnabel delivers dependable excavation support systems to ensure the success of your project.

EXCAVATION SUPPORT SYSTEM SOLUTIONS

Excavation support systems (ESSs), commonly referred to as shoring, play a critical role in stabilizing the ground around an excavation site. These systems are engineered to withstand various forces, including groundwater pressure, building loads, construction traffic, roadways, railways, and other surcharge loads that might impact the site.

Excavation shoring systems can be implemented temporarily to support an excavation until a new structure is constructed, or they can be designed as permanent solutions to sustain the excavation over the long term. The primary difference between temporary and permanent excavation shoring systems lies in the materials used, with permanent shoring often featuring components that are designed for increased durability and resistance to long-term corrosion.

The ideal excavation shoring system for any given project is determined by multiple factors, including soil conditions, required rigidity, and whether a groundwater cut-off is necessary.

Schnabel offers a variety of excavation shoring systems tailored to meet the specific demands of each project, including soldier piles and lagging, soil nailing, secant/tangent piles, deep soil mix walls, and sheet pile walls. These systems are further supported by tiebacks, soil nails, braces, or by designing vertical elements to cantilever. With extensive experience in designing and installing these systems, Schnabel ensures the best-suited excavation shoring solutions for your project, utilizing the most effective methods available in the United States.

EXCAVATION SUPPORT SYSTEM CASE STUDIES

Excavation Support

Capitol Crossing | Washington D.C.

Schnabel designed and installed over 130,000 square feet of excavation support for the Capitol Crossing project in Washington, DC for client Balfour Beatty Construction. Several sensitive structures including the Holy Rosary Church, the Casa Italiana, and a modern office building were supported by a combination of conventional hand-dug underpinning pits, bracket piles, and stiff SASM walls. 

Excavation Support

Reston Row East Promenade Garage | Reston, VA

Schnabel designed and installed a temporary excavation support system for client Davis Construction to facilitate the construction of five-level underground parking garages. In this project, Schnabel installed 120,000 SF of sheeting with over 1,000 temporary tiebacks. The project which took place during the COVID-19 pandemic was completed safely, on budget, and to the client’s content.

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.
