108” Water Line, UPRR to John Ralston

Aurora completed the design of 8,000 LF of 108” water line along West Hardy Rd as part of the City’s NETL. The project includes open-cut crossings at Beltway 8 & CPN pipeline corridor and tunneled crossing at existing 84” water line, UPRR Railroad, and TxDOT frontage roads.

Major challenges included (1) constructability issues with placing the proposed 108” water line close to the existing 84” water line; (2) Crossing the existing 84” water line, Pipeline corridor, and UPRR Railroad; (3) Mitigating bridge settlement risks for BW-8 Bridge; (4) Minimizing impact to High Voltage Transmission Towers in proximity to 108” water line. Aurora, through extensive design alternative evaluation and coordination with stakeholders, developed appropriate mitigation measures and implemented them into bid documents.
