Tectonic was retained to provide structural engineering services for the proposed upgrade of two existing four-circuit electrical transmission towers that bridge the Hudson River in New York.
The existing towers were evaluated for their capacity to support the proposed installation of antennas by various telecommunications providers, as well as for additional equipment required by Consolidated Edison. The services provided have included a structural analysis of the tower, preparation of an engineering report, design of structural modifications, and preparation of construction drawings, as well as detailed steel fabrication and erection drawings, including bills of material.
The work included incorporating current NESC and Con Edison loading conditions, as well as the recent recommendations of the New York State Public Service Commission, all of which are more stringent than the criteria used at the time of the original design and construction. The towers are being reinforced to satisfy the requirements of current codes and standards.
