This document outlines a project for Team Quadcycle to design a vehicle that can be disassembled to fit through small spaces like manholes or valves to transport workers inside water mains. It lists customer needs such as fitting through openings as small as 24 inches, comfortably carrying an adult, and having corrosion resistance. It then provides sections on the team's last design, additional modifications made like a revamped seat attachment, and photos of the fully assembled final product.
