When Bancroft was first approached by DuPont regarding the installation of a code compliant sprinkler system in the Gold Ballroom, foyer, and the Du Barry Room of the Hotel DuPont they knew immediately that this would be a challenging project. Bancroft worked together with the Hotel DuPont to designate a time period when the hotel would be able to close these areas for three weeks (the amount of time that Bancroft allotted for project completion). There were two major challenges involved with this project. The first was schedule, which was crucial due to the fact that these rooms were booked for affairs immediately prior to and following construction and installation. The second challenge revolved around aesthetics and historical integrity. The system would have to be installed so that it would not be detectable to the casual observer and construction had to be completed without disturbing the hotel's irreplaceable original architectural elements and finishes.

Working within the confines of the hotel's busy events' roster required meticulous planning, but protecting its architectural and historical significance called for innovative thinking and a high level of technical expertise. Bancroft involved the primary subcontractors at an early stage in order to anticipate any constructability issues or other problems that might have delayed the project's progress. The team decided to feed piping into the ballroom through the second floor administration offices to avoid any disturbance to the original suspended plaster ceiling. With the use of false valances, the team was able to incorporate the sprinkler system piping seamlessly into the ballroom's ceiling. Once construction began, two ten hour shifts were run daily, including weekends, which allowed some flexibility within the schedule should unexpected conditions arise during construction. Bancroft completed the project in 11 days - 11 days ahead of schedule, and logged 3500 man hours without any safety incidents.
