PROJECT EXPERIENCE – Netflix Studio – Brooklyn, NY

Installation of exterior grouted Ductile Iron Piles alongside a vibration-sensitive retaining wall

Plans for a new 161,000 sqft movie studio required foundation and retaining wall support abutting an existing, vibration-sensitive retaining wall on a portion of the site. While ground improvement was planned for the majority of the project, Ductile Iron Piles were selected to limit vibration concerns in the critical areas. Grouted Ductile Iron Piles were installed through the fill and organic clay to develop working capacities of 40 tons (compression) and 19 tons (tension) through friction in the underlying medium dense to dense sand. Following successful load testing, a total of 195 piles were installed in 11 working days with no impacts to the retaining wall. Learn more about how Ductile Iron Piles provided the low vibration solution for the project. To learn more about the project, check out the full project summary.

PROJECT EXPERIENCE – International Shipping Facility – Philadelphia, PA

Installation of 100-ft long piles within active International Shipping Hub

Construction of a new mezzanine level at an international shipping facility air hub near the Philadelphia International Airport required deep foundations to support loads up to 516 kips at 74 new column locations. Piles were needed to penetrate the soft silt and clay and loose sand extending to depths of at least 65 feet. Overhead clearances were limited to 35 feet in many locations but approached only 20 feet in some areas. Learn more about this PDCA project of the year and how Ductile Iron Piles were installed in the low overhead conditions to depths ranging from 67 feet to more than 100 feet to deliver capacities ranging from 45 to 75 tons.
