The construction of the Walnut Street YMCA on its original 60-year-old site represented an especially ambitious venture. It was the first urban YMCA to be totally rehabilitated in the United States in over ten years. While the nation and the neighborhood watched the project's progress, Bancroft orchestrated 40,000 square feet of construction within an exceptionally constricted site whose perimeter included a residential area and two major roadways required to remain open throughout construction. This made site management, especially for lay down areas and contractor ingress and egress, highly challenging. And because of the building's high-sloped roof, safety considerations called for the utilization of unique lanyard tie-offs to ensure fall protection. Unexpected site conditions created additional stress to the project's inflexible schedule, but Bancroft met all project parameters right on time and delivered a facility that exceeded the Y's expectations.
