25 West 51st Street, Manhattan, 2005. General contractor was Laval Construction.

This extensive structural rehabilitation project of this midtown boutique hotel involved creating a ramp for heavy remotely-controlled digging machines to descend to the work level, breaking up and removing the existing basement floor, excavating and rock removal, the construction of rock anchors which involved the drilling of holes to the bedrock below, grouting the holes and then inserting steel reinforcing bar into the cement-filled holes. A new basement floor was installed and a mat-slab was constructed in the base of the elevator shaft.
