Soil Nail and Shotcrete Wall

Middletown, PA

JG was instrumental in developing the soil nail and shotcrete wall concept required to retain the earth from a new roadway embankment at an existing Facility in Middletown, Pennsylvania.  JG constructed a 500-foot long, 10,500 square-foot soil nail and shotcrete wall in order to re-align a service road at the facility.  The wall averaged 21 feet in height, with a maximum height of approximately 30 feet.  JG installed 400 soil nails and placed over 700 cubic yards of shotcrete.  After the structural shotcrete was placed, JG installed an architectural finish.

Soldier Pile and Lagging Wall

South McKeesport, PA

JG designed and constructed a soldier pile and pre-cast lagging retaining wall at the South Allegheny Elementary School in McKeesport, Pennsylvania.  The retaining wall was designed to provide global stability to the existing fill slope that was previously constructed for the building pad.  The wall included a total of 38 soldier piles drilled 50 feet deep, one (1) row of permanent anchors, and 4,800 square feet of pre-cast concrete lagging.  The work also included drainage and earthwork to restructure the slope.

Hydraulic Press Foundations and Wash Line Pits

Cannonsburg, PA

JG designed and installed multiple cast-in-place concrete wash line pits. The work included geotechnical design parameters and detailed structural designs of the pits and all steel embedments, structural members, and steel plate covers for plant traffic.  Especially challenging in this facility are the high variables and difficult subsurface conditions.

JG designed and installed single and multi-level foundations for this state-of-the-art equipment in very poor soil conditions.  Deep excavations required underpinning of existing adjacent column footings, along with structural excavation shoring systems consisting of drilled-in soldier piles with wood lagging.  The large equipment foundation supports consisted of conventional spread footings supplemented with twenty-two (22) each, 70’ deep helical piles for the heavy point loads.
