We are a group of experienced structural engineers serving architects, contractors, building owners, and developers. Our philosophy is simple, to be adaptable to client needs, providing both design solutions and delivery methods that best serve the requirements of each unique project. Fundamental to this approach is a focus on design and documentation efficiency, eliminating unnecessary complexity and waste, and avoiding redundancy in the design process.
