A long-term client engaged Apex to assist with a stormwater emergency response due to a sudden collapse onsite. The southern side of the employee entrance roadway faced a significant slope failure caused by an outfall pipe deteriorating approximately 20 feet below the roadway. This situation posed immediate safety risks for vehicular traffic, as the roadway serves as the primary access route for all employees. The project was addressed in four phases. In Phase 1, temporary best management practices were used to control water runoff and prevent further erosion. Phase 2 involved sliplining the pipe as a temporary solution while we conducted further investigations of the surrounding soils. An engineered plan for permanent repairs was issued. Phase 3 initiated permanent repairs, which included boring a new 60” RCP pipe under the roadway parallel to the existing outfall pipe and abandoning the old pipe. Finally, in Phase 4, soil enhancements were implemented via compaction grouting to the roadway within 100 linear feet of the abandoned and new outfall pipes. This comprehensive project addressed slope failure, outfall pipe deterioration, and safety concerns, ensuring the continued functionality of the employee entrance roadway. #ApexCompanies #Stormwater #Texas Abby Stanley Edward Coleman
