T-43 Warehouse
T-43 Warehouse
Project Details:
Owner: Forsgate Ventures XII, LLC
General Contractor: Herrod Construction Company, Inc.
Dates of Work: December 2015 - February 2016
Engineer: Melick-Tully
Approximate Key Quantities: Wick Drains - 40000 LF and CMCs - 497 EA.
Project Overview:
T-43 Warehouse is a new 207,000 sq-ft facility located next to the Teterboro Airport in Teterboro, NJ. Although the site contained a previously demolished warehouse, the perimeter of the new facility is larger than that of the previous structure.
Menard was chosen to perform ground improvement to support the new facility in the areas outside the footprint of the previously demolished warehouse.
Wick Drains were proposed to consolidate and strengthen the soils of the new building footprint. However, the owner was concerned about potentially contaminated ground water in an approximately 33,000 sq-ft area. Controlled Modulus Column (CMC)® rigid inclusions were then incorporated into the design in this area of concern to prevent the possibly contaminated ground water from reaching the surface.
Ground Conditions:
Solution:
Because of the site’s proximity to the Teterboro Airport, a challenge on this project was coordinating with the Federal Aviation Administration to meet air traffic height requirements. Every night, Menard was required to lower the wick masts, park the CMC rigid inclusion rig in a designated area of the site, and keep the rigs lit and easily visible.
Wick drain and CMC rigid inclusion installation kept to schedule. More than 40,000 LF of wick drains were installed to an average depth of 67 ft, and a total of 497 CMC rigid inclusions were installed to a maximum depth of 76 ft.
