Dubose, George H.

Charles “Chuck” Allen has over 12 years of experience in building envelope and architecture forensics. His experience and knowledge focus on the control layers of building enclosures, including roofing systems, wall assemblies, cladding systems, fenestration systems, and other design issues that can create opportunities for catastrophic mold and moisture failures. He has applied his expert architectural knowledge and cutting-edge technological skills to some of the world’s largest and most complicated building failure projects, many of which span multiple construction industries. These include the 1.2 Million SF Orlando VA Medical Complex, FRHI 2,000+ rooms in Southeast Asia, Disney’s Grand Floridian Building Envelope refurbishment, and The University of Virginia CAS and ITE building. His ability to efficiently aggregate, organize, analyze and deliver information based on massive data points makes him a necessary part of building forensics projects worldwide. He is also a reviewer of the updated NCARB Mold and Moisture Monograph course. 

George H. DuBose brings over 30 years of experience in building forensics, focusing on failures related to mold and moisture issues. He is the co-author of three manuals on IAQ and Mold Prevention. These manuals, written for the EPA/ASHRAE, NCARB, and a major theme park owner, have been used on over $4B in construction. He has consulted on multiple mold and moisture-related failures across many industries, such as 1.5M SF in healthcare. In hospitality, he has consulted on resorts and hotel projects comprising over 40,000 rooms, including resorts in Southeast Asia. He has also consulted on moisture failures in apartment, student, and senior living housing totaling over 5,000 units, individual residences, and military housing, including one military subdivision totaling over 1,000 homes. In addition, he has consulted on educational buildings and campuses, including one in the Middle East, totaling over $1B in construction. 

Nathan Sanders brings over 20 years of professional experience in building forensics and building systems interactions, focusing on failures that result in microbial, bacteria, and IAQ issues. Professional organizations, including ASHRAE, AIHA, and NIH, seek his knowledge of the design, construction, and building materials to industry partners as an expert on the interactions and issues that arise when building components fail. Across the US, his expertise has been provided to multi-family/student housing developers, totaling $1B+ in construction. He has also provided his expertise to Hyatt Hotels International with $300MM in renovations and temporary housing manufacturers involved in a $145MM+ contract supplying 3000+ housing units to FEMA. In addition, he has been involved with a UNC Wilmington post-Hurricane Florence $150MM+ claim and with $5M in Legionella mitigation for an extensive healthcare system. As an expert witness, he has provided services for clients pursuing and defending claims related to mold, bacteria, and chemical issues that have arisen in the building environment. These matters have included a contractor builder’s risk claim for a $60 Million water intrusion mold problem, a $15 Million developer claim against the contractor for negligent remediation, and a $10 Million homeowner association claim against the designer for a defective design. 

Donald B. Snell has over 25 years of experience with HVAC and building envelope systems mold and moisture failures. In cases where HVAC failure can lead to catastrophic moisture and mold intrusion, he is sought after by building owners, building managers, attorneys, and contractors to determine the issues surrounding these highly complex building failures. His experience has helped defend or recover hundreds of millions of dollars in costs in some of the world’s most complicated HVAC system failures. His diagnosis and remedial solutions have helped some of the largest commercial builders in the world, including NASA, Disney, FRHI, and Hyatt, solve HVAC mold-related failures in their buildings.
