Children's Hospital Sitework
Yale-New Haven Hospital

New Haven, CT

BAC was awarded the Sitework package for the construction of the Children's Hospital at Yale-New Haven Hospital. We built a system of soldier piles and lagging for earth support as we excavated for the deep foundation of the Children's Hospital.

Underpinning and earth support of the existing hospital were necessary before excavating for the deeper foundations of the new building. BAC underpinned some of the existing building and brought in specialists to stabilize the soil in other areas. Soilcrete and chemical grouting were used.

The photo shows soil stabilization under existing columns so we could excavate below the columns later. During this procedure, operating rooms above the columns remained active. The other photo shows the installation of soil anchors as part of the earth support system.
