Excavation Support for a Hospital Addition-PPT Presentation

PPT Presentation

Pdf Summary

The presentation describes geotechnical construction for the WellSpan York Hospital addition in York, Pennsylvania. Wagman Geotechnical Construction worked with the structural, civil, geotechnical, and construction-management teams for two years before construction, supporting permitting and developing a design-build approach for excavation support and deep foundations.<br /><br />The site included existing structures and an anchored retaining wall, with geology that included the Chickies Formation—hard, light-colored quartzite and quartz schist, with dark slate near the top. Excavation support measures included soldier piles and tiebacks, as well as soil nails and shotcrete.<br /><br />The project’s notable challenges and solutions included crane support pads placed over the excavation support system, temporary bracing for a pipe support, permanent support and eventual demolition of an existing anchored wall, and micropiles for both building foundations and a tower crane. The presentation also highlights an investigation into water associated with “Spring Garden,” referred to as “The Spring that wasn’t.”
