Below is an example of a design brief for a bridge design problem, along with three possible specifications. ───────────────────────────── Design Brief The aim of this project is to design a bridge that connects two parts of a community divided by a natural obstacle such as a river or canyon. The bridge must safely accommodate both pedestrian and light vehicular traffic, ensuring ease of access while strengthening community connectivity. The design should balance structural integrity, aesthetic appeal, and cost efficiency, all while being mindful of environmental impact and sustainability. The final design will include innovative solutions that meet modern engineering standards and local cultural influences, and it should integrate seamlessly with the surrounding landscape. ───────────────────────────── Bridge Specifications 1. Load Capacity:  • The bridge must support a minimum live load of 4 kN/m² to safely carry the anticipated pedestrian and vehicular traffic. 2. Span & Clearance:  • The design should include a main span of around 30–40 meters, with sufficient vertical clearance (preferably 5–7 meters) beneath the bridge to allow for unobstructed passage of water and small boats. 3. Material Durability:  • Construction materials should be selected to withstand local environmental conditions (e.g., high humidity, temperature variations, or salt exposure), ensuring a service life of at least 50 years with minimal routine maintenance. ───────────────────────────── These elements create a comprehensive outline for the project, ensuring the design is both practical and forward-thinking.
