DESCRIPTION OF WORK

SOIL STABILIZATION ABOVE GREENLEAF STREET

19TH WARD – CITY OF PITTSBURGH, ALLEGHENY COUNTY, PENNSYLVANIA

This work will install stabilizing treatments on the hillside slope above the western, bottom portion of Greenleaf Street. The work, indicated on the Project documents, generally consists of deep soil mixing and installation of rock buttress, adjacent Greenleaf St, at the toe of the slope and . Work on the upper slope, adjacent the Emerald View Park Trail, includes excavation and installation of soil nails, installation of a line of micropiles with concrete cap and installation of geosynthetically-stabilized soil trail. Work also includes reconstructing a portion of Greenleaf St adjacent the historic slide area.

As background, the existing earthen slope above Greenleaf Street was part of a 2018 slide that destroyed at least one house and closed Greenleaf Street and the South Main Street ramp. To mitigate the risk of a future landslide and its potential detrimental effects on transportation networks, the City seeks to further stabilize the hillside with several landslide remediation techniques.

The work will generally include the following tasks, not necessarily in this order. Some necessary tasks may be omitted from this list:

Design Soil Nail Work Plan, Deep Soil Mixing Work Plan.

Perform Construction surveying.

Install Limit of Disturbance (LOD) work area boundary stakes.

Install erosion and sedimentation measures and rock construction entrance.

Design and implement a Traffic Control Plan.

Perform general site preparations for deep soil mixing work.

Perform deep soil mixing bench scale testing program.

Install deep soil mixed test panel and collect QA/QC samples from the test panel.

Construct the deep soil mixed panels.

Construct rock buttress above the upper row of deep soil mixed panels.

Stabilize the slope around the emerald view trail by installing soil nails and mesh, micropiles and geogrid reinforced slope treatment and the final trail surface.

Reconstruct a portion of the Greenleaf street pavement.

Topsoil, seed and mulch disturbed areas. Remove erosion and sedimentation measures.

Removal of any traffic control measures.

ALL WORK IS TO OCCUR IN ACCORDANCE WITH THE CONTRACT DRAWINGS,

SPECIFICATIONS, GENERAL AND SPECIAL PROVISIONS.
