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.

West Chestnut Street Widening - Washington County - SPK provided preliminary and final design engineering services for a 1.25 mile widening and resurfacing project through a heavily traveled urban corridor. SPK completed pavement, drainage, retaining wall, sidewalk/ADA and traffic signal design services and coordinated a substantial utility relocation effort. SPK worked closely with the District by leading public and public officials meetings with property owners to address public concerns regarding parking, driveways, right-of-way takes, landscaping and building entry.
