“Solving problems is extremely rewarding for me. The range of problems I get the opportunity to help resolve is the biggest reason I enjoy my work. Whether I’m developing a repair for a 100-year old masonry building, doing a peer review or hygrothermal analysis for a new structure, or simply helping to resolve leakage issues into a modern building, I find satisfaction in the ultimate resolution of all these issues. Keeping an open mind is key for me because there are so many factors that can contribute to the cause and ultimate resolution of a problem.”

Technical Papers/Publications & Speaking Engagements

Rex has authored and co-authored numerous articles published in technical journals and frequently appears at national conferences to present his publications. Many of his publications and presentations focus heavily on the building envelope from the design phase, proactively working to prevent design problems, to the rehabilitation and repair phase, correcting issues that commonly plague the building envelope, such as water infiltration. His most recent publication at the 13th Canadian Masonry Symposium in Halifax, Nova Scotia, in June 2017 was titled “Performance of Historic Mass Masonry Walls Utilizing In-situ Measurements,” which was co-authored with Annette Cyphers, P.E., Director of Facilities Planning and Construction at the University of Virginia, and Jodi Knorowski, P.E., Senior Engineer at WDP.
