Sean Rennau
Sean Rennau

Mr. Rennau has over 15 years of combined experience in the Civil Engineering and Landscape Architecture fields. His employment with traditional design-build firms has garnered experience on a variety of Civic and Residential projects from across the Midwest. His understanding of the design process and experience in the construction industry has honed his abilities to listen to project owners and work with Architects, Engineers, and Contractors in the optimal development of exterior spaces and habitats. Mr. Rennau’s diverse background provides the means to better understand the scientific and aesthetic principles of Civil Engineering projects.

Since joining the AECI Team in early 2015, Mr. Rennau has worked on a variety of projects for commercial sites, multi-family developments, residential subdivisions, and public streets. As a part of those projects Mr. Rennau has been directly responsible for site layout, storm sewer design and calculations, landscape design, sanitary sewer design, water main design, and local and state permitting. Mr. Rennau’s education and experience in both Civil Engineering and Landscape Architecture make him a valuable asset for AECI and it allows him to offer a more comprehensive ability to exercise his passion for improving the human condition in tandem with our natural environment.
