About the Presentation: 

“Drilled Shafts Remediation Using Micropiles” was first presented at the daylong ASCE Symposium held in ASCE HQ in 2025. This presentation highlights the remediation of deficient drilled shaft foundations for the I-64/I-264 Ramp Improvement Project in Norfolk and Virginia Beach, Virginia. The project involved addressing both structural and geotechnical deficiencies identified during construction of critical transportation infrastructure foundations. Micropiles were utilized as a practical and cost-effective solution to restore foundation capacity and performance while minimizing impacts to project schedule and operations. The presentation discusses the evaluation process, design approach, construction challenges, and lessons learned from implementing micropile-based rehabilitation measures. The case history demonstrates how micropiles can effectively resolve complex drilled shaft deficiencies and provide long-term foundation reliability for major infrastructure projects..
