Regional Experience in Transportation Engineering

When it comes to designing public infrastructure such as streets, highways, and bridges, trust is essential.

The engineers at Klingner have designed or rehabilitated over 400 roadways, freeways, streets, and bridges projects in the past 15 years alone. These tried and tested teams have coordinated and developed all phases of work orders — including initial studies, final designs, and construction inspection — for municipalities, counties, and Departments of Transportation.

They’re also the ones doing the work. The team you meet and communicate with are the same individuals designing your project, ensuring consistent quality from start to finish.

Quality Control / Quality Assurance

Early and clear coordination is essential. We assign project managers as the single point of contact for all inquiries, deliverables, and deadlines from authorization to close-out. Before the project begins, Klingner’s engineers will work with you to define the scope of services – outlining tasks, schedule, deliverables, and other work requirements specific to your project.

Combined with our regular internal meetings, monthly client updates, and peer reviews, this tool is instrumental in maintaining our high levels of plan accuracy and project documentation.
