Our professionally licensed structural engineers utilize the latest in technology to provide safe design and innovative solutions for industrial, government, medical, residential, and educational projects. From residential homes to schools, hospitals, and bridges. No project is too big or small.

We have a reputation for providing quality, timely structural engineering design services.  TD&H Engineering is highly qualified to design, detail, and prepare construction documents, offering full-service structural services. We also provide investigations of all types of buildings and structures and address renovation and design solutions for all types of problems.  Our structural engineers serve as project managers capable of providing the design and construction lead for clients trying to obtain a quality structure with budgetary and time constraints.

TD&H Engineering is proactive in using the latest International Building and Residential Codes and respective discipline codes to provide clients with safely designed structures.  We also use the latest computer drafting software including Revit, a three-dimensional Building Information Modeling software used for building and component designs.  This software provides the owner with a more realistic model of how the final structure will look and helps to detect design concerns and interferences before they are placed on the plans.

Of our dozen structural staff and professional engineers, several are licensed as structural and several hold PhDs. With many years of experience, our structural engineers have gained the skills needed to execute these projects.
