摘要

DC Water is improving water quality in Washington DC by replacing aging pipelines. The Oregon Avenue NW Sewer Rehabilitation project was constructed by Bradshaw Construction to replace and improve sewers in Rock Creek Park and Bingham Drive. Of the project’s 4,300 feet of new 24-inch sewer, 2,700 feet was installed by microtunneling through the variable rock conditions at up to 90 feet deep. Work areas were particularly challenging as the project was located between a quiet, residential neighborhood and Rock Creek Park. Access had to be maintained for residents, emergency services and visitors to the National Park. To minimize public impact, Bradshaw reduced the 7 designed tunnels to 3 including a single 1,860-foot drive and a 430-foot S-curve with a 625-foot radii. The collaboration and flexibility of the Oregon Avenue team allowed the project to show how far we can push the push the capabilities of microtunneling.
