Prologis Ports Pulaski Warehouse
Prologis Ports Pulaski Warehouse
Project Details:
Owner: Prologis, L.P.
General Contractor: RC Andersen, LLC
Duration of Work: 23 weeks
Subsurface Conditions: Dynamically compacted fill over peat soil overlaying varved silts and clay
Approximate Key Quantities: 11,900 Controlled Modulus Column (CMC)® rigid inclusions
Project Overview:
This project involved the construction of an 878,000 square foot distribution center built by Prologis, a global provider of industrial real estate. The warehouse is adjacent to the Pulaski Skyway in Jersey City, New Jersey. The former landfill site was placed on the US Environmental Protection Agency’s National Priorities List (superfund) requiring extensive remediation after it was discovered that various chemicals in the landfill were spontaneously combusting. To improve the highly contaminated in-situ soils and support the foundations, Menard proposed Controlled Modulus Column (CMC)® rigid inclusions as an alternative to traditional pile foundations.
Ground Conditions:
Solution:
Thousands of CMC Rigid Inclusions were installed to support the building slab, interior columns of the warehouse, perimeter wall footings, and a utility farm outside the warehouse footprint. Installed concurrently with 6 drill rigs, the CMC Rigid Inclusions were designed to withstand a bearing pressure of 800 psf under the floor slab and 1,330 psf under the footings. The settlement criteria for the warehouse was between 1.1 and 1.8 inches total for the footing and between 1.4 and 2.2 inches total for the floor slab. A ½ inch differential settlement criteria was maintained.
The use of CMC Rigid Inclusions was more economical than traditional foundation supports and offered substantial savings by allowing the client to eliminate the reinforced slab and pile caps. Additionally, this ground improvement solution was environmentally sound due to the minimal spoils associated with the displacement drilling of CMC Rigid Inclusions.
