At SEI, our staff takes a holistic approach to design. We involve the entire team in the process to get the best result possible. Landscape Architects at SEI play a pivotal role in this process. Where other firms treat required landscape plans simply as necessary steps in the permit process, at SEI we do our best to produce plans that will not only meet minimum requirements but will also be economically and aesthetically desirable. Our Landscape Architects are a creative group, capable of producing a wide variety of detailed plans.

With construction management services, SEI assists our clients in the successful and safe completion of their projects and programs. SEI works alongside the architect, engineer, and owner to optimize the project design, schedule, and cost. From pre-construction to construction to post-construction, SEI functions as an extension of our clients, putting their best interests first and handling every aspect of design and construction delivery. We are focused on solving any conflicts proactively and collaboratively rather than merely cutting costs.

SEI's land-surveying department is truly integrated with the firm's engineering, planning, traffic, and transportation operations. The surveyors are highly trained and dedicated professionals committed to quality service. They work with state-of-the-art equipment that is continually upgraded to keep pace with technological advances and have the experience and sensitivity to anticipate client needs, as well as the knowledge and ability to avoid costly problems and unnecessary work. The land-surveying staff are career-oriented individuals selected for their excellent educational and exceptional experience credentials.

SEI provides comprehensive environmental services to both public and private sector clients. We have extensive experience with complex and evolving governmental regulations, policies, and guidelines. SEI works to address issues of natural resource management, ecology, air/water quality, noise impact, flood risk, transportation planning/documentation, socioeconomics, jurisdictional waters of the U.S., state waters, protected species, urban planning, landscape architecture, permitting, tree surveys/recompense, and many other environmental considerations.

More and more local and national developers are turning to SEI for their civil engineering, planning, and a wide range of design services. We have gained their attention (and business) through a reputation built upon numerous successful public and private landmark projects in the metro-Atlanta area and beyond. SEI has the experience and depth of technical resources to provide outstanding technical services to support many types of development projects. SEI project experience includes developments ranging from multi-jurisdictional high density mixed use developments to master planned single-family communities and 1 million plus square foot industrial buildings.
