Confidential Hospital

Case Study Overview


Water can be a damaging force. A trickle can turn into a downpour, and a leak can signal a flood. With one hospital, moisture had invaded from all angles––including standing water in its basement and crawl spaces, flooded parking lots, mold behind vinyl wall covering, and more. GHP was called in to identify the cause and develop a solution that would not only clean up the moisture damage, but also prevent it from returning.


Having relied on GHP to solve complex environmental and structural issues at other properties, hospital ownership called in our forensic team to chase down multiple lines of investigation into the causes––from air quality to drainage to mold assessments.

Environmental and indoor air quality tests revealed the building was under negative pressure––drawing airborne moisture into the facility and trapping it there. Our team analyzed the exterior drainage sites, discovering that rain leaders and roof drains were dumping water directly onto the ground and creating a hole that channeled moisture directly into the hospital’s basements and crawl spaces.

To correct the facility’s interior negative pressure, GHP partnered with the hospital’s HVAC vendor to rebalance and upgrade their system. Working with the hospital’s infection control specialist, the team set up containments to safely strip contaminated vinyl wallpaper, remove mold and refinish the facility’s walls in the midst of a still functioning ICU.

To manage public perception throughout this process, GHP maintained strict confidentiality that extended to its environmental partners who removed any mention of environmental clean-up from their uniforms.

Additionally, our team re-engineered overall site drainage, navigating difficult access points like interior courtyards and low clearance areas. We also coordinated with local stakeholders including the region’s railroad company to reconstruct a main drainage ditch that neighbored railroad tracks.


Throughout GHP’s work on this project, a single root cause emerged: insufficient attention to maintenance. While seemingly insignificant in the moment, inadequate care through the years had led to the hospital’s moisture issues. To prevent future issues, GHP provided hands-on training for hospital employees detailing how to keep drainage pathways open and clear. From site investigation to environmental remediation to preventative instruction, the hospital was left with a clean, safe facility and with the tools to keep it that way.
