Wagman’s Geotechnical Construction group was subcontracted to design and install two temporary support of excavation walls so the excavation can be completed for the WellSpan Health’s Surgical & Critical Care Tower. The first wall is 650 feet long and up to 39 feet tall upon completion. The shoring system was designed to have cranes, concrete pump trucks, and stone throwing trucks sitting on top of the wall which assisted with the construction without impeding traffic on the nearby road.
The second wall is 445 feet long with a maximum height of 23 feet and was constructed by installing rock bolts and shotcrete. This wall is located through the middle of the project site so the basement and first floor were able to be constructed.
Wagman designed and installed 47 micropiles for several footings next to the existing hospital to eliminate the need for additional excavation and temporary shoring. Wagman also designed and installed a micropile foundation for 227’ tower crane which was erected late 2024.
Key Challenges & Project Details
- The project is on an accelerated schedule so there are existing utilities in the excavation area that have to be protected until they can be relocated.
- The project will have limited access once the excavation is complete, so Wagman designed the SOE system to allow rough terrain cranes to sit on top of the wall.
- This is the second time Wagman has provided geotechnical construction services to WellSpan York Hospital.
In 2015, crews finished excavation support with tiebacks for an Emergency Department expansion project.
