Soil excavation for remediation of an oil pipeline release located under land designated for a future residential development. Excavation depths varied across the site reaching maximum depths of 32’. Over 90,000 tons of impacted soil was direct loaded for transportation and disposal as Non-Hazardous material. A 40’ deep beam and plate shoring system was engineered and installed to protect existing utilities. Removal and replacement of gas, water & sewer utilities was also required. Certified backfill and compaction was part of the site restoration as well as construction of residential house pads that had been demolished during excavation. Maintenance of over 1 mile of county road that was utilized has the haul road continued throughout the project. Asphalt resurfacing was performed to close out the project site restoration.
