O&A has designed extensive amounts of concrete design projects for many different purposes. Structural concrete design can be utilized for commercial, municipal, and residential structures. Concrete can be used in floor systems, wall framing, outdoor decks, stair systems, and much more. O&A uses a wide variety of computer-based software to simulate the different loads that may affect any part of the structural concrete member. The use of concrete design is common among commercial and residential design. Through these concrete design projects, O&A produces the necessary drawings, documents, and specifications to complete the project. Each set of drawings includes a comprehensive set of plans and details specific to that unique project.  O&A designs each project based on the most recent and up to date Building Codes.
