Completing Ongoing Hospital Repairs with no Disruption to Patient Care

Project Background

• York Hospital first opened its doors in 1880 as a small local hospital; it now serves over 500,000 people in South Central Pennsylvania
• MPS first began work at the hospital in 1990 and has completed over 70 projects since then
• Projects have ranged from full masonry facade restoration to the installation of a single trench drain

Projects of Note

Original 1929 Building

• In 1991, during a severe thunderstorm, a piece of cast stone spalled from the building facade and fell onto a lower roof
• MPS determined that due to age, water saturation, and a lack of adequate flashing, deterioration of the cast stone pieces had threatened their stability
• Over several years MPS worked to remove the deteriorated cast stone pieces, install new state-of-the-art flashing, and selectively replace the cast stone with brick to match the building’s original brick
• At the hospital’s main entrance, new cast stone was installed with side anchorage, ensuring that the new flashing would not be breached

Project South

• When an OR addition was constructed adjacent to Project South, leaks were immediately reported below the interface between the addition’s roofs and the walls of Project South
• MPS determined that there was not adequate flashing at the roof interface and any water that was entering Project South’s walls was circumventing the roof flashing
• MPS developed a work scope to properly flash the Project South walls and completed the work while operating room use continued
