Dewberry receives three ACEC NY Engineering Excellence Awards
Dewberry, a privately held professional services firm, has announced that it has earned three Engineering Excellence awards from the American Council of Engineers Companies (ACEC) New York chapter. The awards will be presented during the annual gala in April 2022.
Diamond Award: City Island 20-inch Sub-Aqueous Water Mains To improve water capacity and infrastructure resilience for City Island, the New York City Department of Design and Construction (NYCDDC) and the NYC Department of Environmental Protection selected Dewberry to design redundant, 20-inch sub-aqueous water mains, which were installed by drilling underneath the Eastchester Bay. Due to restrictions at both the launch and landing points of the trenchless technology installation, and considering parks department trees, wetlands, city streets, and seawalls that could not be disturbed, Dewberry selected a never-before-used in New York City method to directionally drill the two water mains in a compound curve. The mains would be installed in a three-dimensional compound curve through the bedrock below the waterway between the Bronx and City Island. The use of the compound curve would minimize impact and hit the targets needed to reach project goals.
