Abstract: Embodiments described herein include systems and methods for efficiently assembling a structure. In one embodiment, a system includes multiple panels, with each panel having a frame made of multiple members. Each member of the frame has at least two pairs of passageways. Each pair of passageways can include two passageways that intersect each other in a perpendicular manner. Furthermore, each passageway may pass through, and be oriented orthogonal to, the longitudinal axis of the member. The first pair of passageways can be spaced a first distance from the first end of the member, while the second pair of passageways can be spaced a second distance from the second end of the member. In some embodiments, the first and second distances are approximately equal to one another. This consistency allows for maximum interchangeability and compatibility of the members and/or panels.
