INCA Engineers provided design, construction management services, and on-site inspection for the restoration of a portion of Marine View Drive roadway that had slid approximately 10 feet due to an, approximately 400-foot wide, adjacent landslide. This project included the design of a 150-foot long space pile wall consisting of 5-foot diameter by 25-foot deep lean concrete lagging shafts and 4-foot diameter, 75-foot deep structural concrete shafts. The effort included evaluation of alternative retaining wall systems and coordination of geotechnical efforts.
