Pinnacle Health West Shore Hospital Segmental Retaining Wall (Mechanicsburg, PA)

ELA Group was contracted by Pinnacle Health West Shore Hospital to design three segmental retaining walls for the hospital and parking area expansion plan.

The segmental retaining walls were a site-critical amenity required to provide support for the proposed parking lots and sidewalks located directly behind them. ELA designed the three walls, each 13,550 square feet, utilizing Keystone Compac III segmental retaining wall blocks with a near vertical batter.

The area behind the walls was insufficient to construct the required guiderail, therefore, ELA proposed and designed a mixed use concrete and Compac III block parapet design. At the rear of the parapet, reinforced concrete was used; at the front of the parapet, ELA utilized the Compac III blocks to keep a uniform look to the wall. The crucial part of the parapet design was to ensure that the parapet could withstand a vehicular impact without failure, for which ELA conducted the vehicular impact study and design.
