Dr. Williams is the President and Founder of Facility Engineering Services. He has extensive experience in the structural, functional, and life safety design of agri-industrial (food, agricultural, and bioprocess) process facilities including USDA and FDA inspected facilities. He has extensive experience in the design and analysis of concrete and steel bulk storage and their associated material handling systems. He is an accomplished engineer, integrating structural engineering, architectural engineering and agricultural process engineering. As part of his practice, Dr. Williams has integrated his knowledge of food & agricultural process engineering with facility layout and design. He has an advanced level technical competency in the design procedures for all major materials of construction and has developed novel and complex solutions for facility construction using these materials. He has extensive experience using the design-build project delivery method. Dr. Williams has taught construction methods and building codes at the University of Wisconsin.

PEI Professional Engineer of the Year Award

Dr. Williams is the recipient of the ASABE 2915 PEI Professional Engineer of the Year Award.  This award honors a licensed engineer who has made outstanding contributions to the agricultural engineering profession, the public welfare, and/or humankind.

Henry Giese Structures and Environment Award

Dr. Williams is the recipient of the 2015 ASABE Henry Giese Structures and Environment Award.  This award is given “For distinguished service in advancing the knowledge and science of agricultural structures and environment”. Honorees are chosen based on their advancement of teaching, research, design, and basic knowledge of agricultural structures and environment including livestock and poultry buildings, plant growth structures, crop and other storage processing structures, and rural human housing. The award was established in 1988 by the family of Henry Giese to honor his lifelong accomplishment in farm building design, research, and teaching.
