Never forget

Building it back

As part of the reconstruction at the World Trade Center, Halmar was responsible for the construction of the foundation within a 100-foot-deep slurry wall. The foundation included 130 high-capacity anchors, and special grouting to protect the adjacent subway station. Halmar kept the foundation project on schedule despite severe design changes. Being the prime contractor on site, Halmar ran site logistics, provided tower cranes for operations and other trades. As one of the most complicated and congested construction sites in the nation, Halmar adhered to unique restrictions and safety requirements, together with specific traffic control and protection measures. Rock excavation was completed by drilling, controlled blasting, mechanical and chemical demolition. Halmar was also responsible for the control of groundwater in the rock excavation. Controlled blasting was executed with complicated logistics including muck disposal, rock bolting and extensive drilling for mechanical/rock demolition. The superstructure, which was awarded based on the successful performance of the foundation work, was the most complicated of all towers. It has the largest footprint, with massive core sheer walls. Halmar introduced value engineering by substituting high strength steel in lieu of normal rebar, which was fabricated at Halmar’s offsite rebar facility in Maybrook, NY.
