Our success is fueled by our ability to provide innovative solutions for all aspects of highway design that minimize design, construction, and future maintenance costs, while meeting schedules and staying within budget. By carefully listening to our clients’ needs we develop cost-effective, constructible designs that meet their objectives. We understand there is often more than one alternative to meet the objectives of a project and that construction costs must be weighed against potential benefits.

Our commitment to sustainability propels us towards context sensitive solutions that leverage new technologies and minimize environmental impacts. We work closely with communities, private industry, and government agencies at the state and local level. Our ability to deliver full project support from alternative alignment studies through final design and construction inspection/consultation helps us uncover efficiencies and cost-savings opportunities throughout the process. Our design process follows the strict requirements of LDG’s QA/QC policy which ensures constructible projects of the highest quality.

Each project is an opportunity to improve safety and connect people. We take this responsibility seriously.
