At its regularly scheduled Board of Directors meeting on Tuesday, November 17, the Alexandria Renew Enterprises (AlexRenew) Board awarded a US$454.4M contract to the Traylor-Shea Joint Venture to design and construct the RiverRenew Tunnel System Project. This marks a major milestone to comply with a 2017 Virginia law to deliver cleaner, healthier waterways to Alexandria by July 2025.
The RiverRenew Tunnel System Project includes a 3.2km (two-mile) long, 3.9m (12-foot) diameter tunnel to be constructed by TBM, shafts, and other sewer infrastructure that will help prevent about 130M gallons of sewage from polluting the Potomac River, Hunting Creek, and Hooffs Run each year. The Project will solve a sewer issue dating back to the mid-19th century. AlexRenew, with support from the City of Alexandria, has been working to implement the RiverRenew program since 2018.
Traylor-Shea was awarded the contract to complete the final design and construct the Tunnel System Project. The Traylor-Shea design-build team consists of Traylor Bros, Inc., and J.F. Shea Co., a joint venture, with support from Jacobs Engineering and Corman Kokosing Construction Co..
“AlexRenew is excited to partner with Traylor-Shea to improve the health and quality of Alexandria’s waterways on RiverRenew, the largest infrastructure project in the City of Alexandria’s history,” said Karen Pallansch, AlexRenew CEO. “In spite of a government shutdown, an ongoing pandemic, and other hurdles, RiverRenew is on track to meet its incredibly aggressive completion timetable. AlexRenew will continue to fulfill our vital mission to clean wastewater, working collaboratively with our community to solve our environmental challenges proactively and through effective local, long-term investments.”
