Environmental Remediation and Underpinning for November Sky, LLC

Shore Systems Group, LLC was directly contracted by November Sky, LLC to execute a complex environmental remediation and foundation underpinning project at a former gasoline station and mechanic shop, now operating as a metal fabrication facility in Bayville, NJ. This project required a strategic approach to excavation, shoring, and foundation stabilization while maintaining ongoing business operations.

**Environmental Remediation and Underpinning Project in Ocean County, NJ**

Project Overview

What

The project focused on environmental remediation and foundation underpinning at a former gasoline station and mechanic shop. The site, currently utilized as a metal fabrication facility, required excavation of petroleum-impacted soils and structural reinforcement to ensure long-term stability.

Where

385 Route 9 (Atlantic City Boulevard) Bayville, Berkeley Township, Ocean County, NJ

When

The project began with helical pile installation from September 16 to September 18, 2024. Asphalt and concrete removal followed on September 19, leading to shoring installation, soil excavation, and backfilling, which continued through October 3, 2024.

Methodology

How

Shore Systems Group implemented a combination of underpinning and environmental remediation techniques:

Installed (5) 2875.203 helical underpinning piles to a maximum depth of 21 feet below grade.
Constructed a 2-Bay Slide Rail Environmental Pit (41'L x 14.76'W x 16'H) to facilitate soil excavation and containment.
Addressed petroleum-impacted soil and groundwater following previous inadequate remediation efforts.
Excavated soils from 12-17 feet below grade and safely disposed of contaminated material.
Managed groundwater at 14 feet below grade to prevent running sandy soil from compromising stability.
Applied PetroFix to excavation floors and sidewalls before backfilling with crushed stone and stockpiled overburden.

Why

Petroleum contamination persisted at the site due to previous incomplete tank removals and limited excavation. The underpinning system ensured the structural integrity of the facility while the excavation and decontamination process took place. Groundwater control was crucial to maintaining site stability and preventing further contamination spread.

Overcoming Challenges

Problems and Solutions

Mismarked Public Utilities: Gas and water lines were inaccurately marked during previous surveys. A private utility locating contractor was engaged to provide precise utility locations, ensuring the safety of excavation and shoring activities.
Shoring Reconfiguration: Due to the discovered utilities, the slide rail shoring plan was modified to avoid interference, preventing potential damage and service disruptions.
Maintaining Business Operations: The project required excavation activities within an active business. Shore Systems Group worked closely with facility staff to develop a traffic flow plan, ensuring employee and public safety while allowing metal fabrication operations to continue uninterrupted.
Storage and Site Logistics: With significant space occupied by shoring equipment, dewatering systems, and stockpiled overburden, careful coordination was essential to optimize storage and maintain accessibility.

Conclusion

Through innovative engineering, careful planning, and close coordination with November Sky, LLC, Shore Systems Group successfully executed the environmental remediation and foundation underpinning project while allowing business operations to continue. This project exemplifies Shore’s ability to navigate complex environmental challenges and execute foundation solutions with precision and efficiency.
