• 41,000 SF (28,000 exposed SF) of slurry wall installed from late December 2000 until early February 2001. The Cashman/Nicholson J.V. met the goal of a panel a day, 6 days per week under extreme winter conditions.

• The Cashman/Nicholson Team performed combined excavation and bracing operations under very restricted operating conditions. Excavation was performed in 3 stages to allow the installation of two levels of intermediate temporary bracing and the final substructure waterproofing and protection systems. The final depth of excavation was, approximately, 45 feet below grade. The team choreographed the bracing and excavation operations to complete the overall operation in record time.

• The two levels of bracing required over 1,200 tons of heavy 30 and 36 inch rolled sections and required over 17,000 man-hours to install and remove. Removal operations were coordinated with the General Contractor, a joint venture of Clark Builders and Suffolk Construction, and were performed as the permanent structural support system was constructed.
