Haley & Aldrich responds to natural disaster and quickly reopens a critical commute route 

40 days

taken for repairs; half of the time expected

25,000 cars

travel the route per day

Summary

  • Severe storms in December 2022 resulted in a retaining wall failure that closed part of A Street in Castro Valley, California.
  • Alameda County leaned on Haley & Aldrich to design the emergency repair and provide construction services for this essential commuter route.
  • With our in-house LiDAR capabilities, we quickly developed a digital twin of the site conditions, which accelerated the design process. 
  • Haley & Aldrich’s staffing flexibility and its effective communication with the county, the contractor, and utility owners made it possible for the contractor to work seven days a week, 12 hours a day. This schedule effectively cut the construction phase in half, from 12 to six weeks.
