Dean Lewis, P.E. , S.E.


Director of Mass Timber and Prefabrication Skanska

Before joining Skanska, Lewis was with Alphabet-funded Sidewalk Labs for two years, working on new construction technologies in the mass timber space. He has also worked for Swinerton Mass Timber (Timberlab) (2019-2021), DCI Engineers (2010-2019) and the U.S. Army Corps of Engineers (2009-2010).

During his career, Lewis has overseen multiple mass timber construction projects including office buildings, campus dorms, multi-family developments, and hotels. He has an extensive experience with design and fabrication, project management and delivery, logistics, and procurement, among other aspects of the construction process. He has also been part of published research projects within the mass timber space.

Lewis graduated from Washington State University (WSU) where he earned a Bachelor of Science in Civil Engineering and a Master of Science in Structural Engineering. At WSU, he studied under Dr. J. Daniel Dolan, P.E., a premier figure in the mass timber industry, who inspired him to pursue a career in the field. Lewis is following a similar career path to his father, who worked in construction, and his grandfather, an architect.

Mass Timber Hybrids at Different Scales – A General Contractor’s Perspective

As part of Skanska’s sustainability goals, teams are looking to decarbonize future projects with mass timber. With new land-use policies and adoption of new building codes, Skanska’s Development, Construction, and Self Perform construction teams are looking at ways to utilize mass timber in buildings. While Skanska has examples of mass timber projects which consist mostly of timber (which enhances the speed and execution of the project), other projects still require steel and concrete. This presentation will provide a case studies and examples of how hybrid construction can positively or negatively affect the overall project success and the factors that lead to the benefit or detriment of the project.
