Emergency Retaining Wall Replacement
Project Cost: $3.89 million
County: Washington County
Client: PennDOT District 12-0
Contact: Mr. James Sisul, P.E. (724-439-7379)
This project involved the expedited design and construction of a failing concrete cribwall. Several options were investigated focusing on tie-back pile and lagging alternatives that permitted the existing wall to remain and minimize the impacts to Tenmile Creek. A hybrid anchored sheet pile-drilled pile retaining wall was advanced based on a collaborative effort with District Design and Construction staff, geotechnical design services provided by Earth, Inc., and a contractor. The initial meeting was held on the project site June 13, 2013 (Emergency Proclamation dated June 11, 2013). SPK delivered the final mylars July 31, 2013 for construction.
