Anacostia River Tunnel ISCT Excavation

The District of Columbia Water and Sewer Authority (DC Water) distributes drinking water and collects and treats wastewater for more than 600,000 residential, commercial and governmental customers in the District of Columbia. As part of this mission, DC Water operates the Blue Plains Advanced Wastewater Treatment Plant (BPAWWTP), the largest such facility in the world. The Authority’s $2.6 billion long-term control plan for combined sewer overflows (CSOs), known as the DC Clean Rivers Project, captures CSOs and conveys them to the BPAWWTP for treatment. The Clean Rivers Project is comprised of a system of 20 miles of 23-foot-diameter tunnels at depths from 50 to 160 feet. HAKS is a member of the consultant construction management (CCM) team providing inspection services, including tunnel and near-surface construction, for both the Anacostia River and Blue Plains design-build tunnel projects. Giant tunnel boring machines (TBMs) are being used to bore the underground structures that form DC Water’s solution to CSOs. Continue Reading…

OneNYC: The Plan for a Strong and Just City

DSC07801 REVLast month, New York City Mayor Bill de Blasio released OneNYC: The Plan for a Strong and Just City, the successor to Mayor Michael R. Bloomberg’s PlaNYC. The Mayor’s Office of Sustainability oversaw its development and shares responsibility with the Mayor’s Office of Recovery and Resiliency for ensuring its implementation. OneNYC addresses challenges such as a population of 9 million by 2040, changing climate conditions and aging infrastructure through principles of growth, sustainability, resiliency and equity. The plan builds on the four core challenges addressed in past PlaNYC reports with the addition of growing inequality, the importance of the region and New York City “voices”—a reference to the necessary input of a broad range of residents. The plan also acknowledges the growing gap between “technology haves and have-nots.” Continue Reading…

Recommissioning of Gilboa Dam

Recommissioning of Gilboa

Recommissioning of Gilboa

On October 31, 2014, HAKS Senior Vice President Al Lopez, P.E., and Vice President Todd Yanoff, P.E., of our Water/Wastewater Group, joined New York City Department of Environmental Protection (NYCDEP) Commissioner Emily Lloyd and other dignitaries at the recommissioning of the Gilboa Dam in Schoharie County, New York.  A HAKS-led joint venture has been providing Construction Management services for the rehabilitation of the dam—the firm’s largest construction management project to date and believed to be the largest public works project in the Catskills. D&B Engineers and Architects, PC/URS was our joint venture partner; Gannett Fleming/Hazen and Sawyer joint venture was designer; and Barnard Construction/DA Collins joint venture was the contractor. The NYCDEP initiated this $400 million project to extend the life of the dam another 100 years and bring it into compliance with New York State Department of Environmental Conservation safety standards. Says Commissioner Lloyd, “This was a safety project foremost.” Phase 3 of this massive undertaking, the $138 million reconstruction of the Gilboa Dam, has been completed two years ahead of schedule in spite of a nine-month delay caused by Tropical Storm Irene.
