These are engineering design drawings for a landslide remediation project by Ackenheil Engineers, Inc. for the CBS Radio Tower and Broadcasting Facility located at 107 Reese Street in Pittsburgh, Pennsylvania. The drawings detail two specific retaining walls (CBS Wall #1 and #2) with precise technical specifications for soldier pile wall construction.

The technical drawings provide comprehensive details on wall construction, including 14 total soldier piles (12x63, 50 ksi grade) with 24" drilled shafts, reinforced concrete cap beams, and detailed soil stratification information. The walls are designed to address a landslide area, with specifications for different soil layers including medium dense fill, claystone, sandstone, and bedrock. The drawings include plan and elevation views, noting precise elevations, pile placements, and construction materials such as wood lagging and gravel fill. The project was prepared by BRH for Ackenheil Engineers, with drawings dated 1/30/19 and 3/01/13, indicating a multi-phase design and review process.
