Cornerstone Structural Engineering Group, Inc. has just been awarded two awards for their structural engineering projects through the American Society of Civil Engineers (ASCE) Fresno Branch. Seneca Lane Mudslide Sewer Stabilization was awarded Outstanding Structural Project of the Year. The Hardin Flat Crossing South Fork Tuolumne River Bridge (HBP) was awarded Outstanding Roadway and Highway Project of the Year.
The Seneca Lane Mudslide Sewer Stabilization Project included the design and construction of a new tieback wall measuring 168 feet long and 16 feet tall to restore functionality of a 6-inch diameter sanitary sewer line and mitigate future slide events in San Mateo County, CA. The design teams coordinated closely with the County and construction crews to overcome a number of obstacles for construction including: active slide conditions, difficult site access, power outages, and schedule constraints in order to complete the wall before the rains returned.

The Hardin Flat Crossing South Fork Tuolumne River Bridge Project included the design and construction of a new 120 foot long clear-span, cast-in-place, post-tensioned, concrete box girder bridge in Tuolumne County located just outside the SR 120 entrance to Yosemite National Park. The original timber bridge was damaged in the 2013 RIM Fire and the replacement bridge was vital in connecting Berkeley Tuolumne Camp to State Route 120. The project site is in a relatively remote location which required close coordination with shipping companies, contractors, and material suppliers while evaluating constructability of the proposed replacement bridge.

These awards were presented to Cornerstone Project Manager, N. Bobby Zermeño, at the Annual Awards Luncheon on September 17, 2020.
