Services - Detailed Design - Structural EngineeringSega has been providing structural engineering services since 1987. Our engineers have over 80 years of experience designing a wide array of structures made of steel, reinforced concrete, masonry, and other composite materials for the construction of new facilities or improvements to existing facilities.

We understand the natural forces and the most recent building codes that affect the design on your project and we can present multiple options for your consideration. Every project is different but one thing remains unchanged, you need solutions that will keep your project ahead of schedule and within the budget. Access our database of experiences and lessons so we may work with you to achieve your goals.
