One Design allows for earlier coordination, saving time and money on Shop Drawings Coordination at the back end. Think of a building’s mechanical, electrical and plumbing (MEP) infrastructure as its central nervous system. These systems must run in synergy in order to be effective. Historically, to get to that point, MEP trades coordinate the work after contract award because bid documents don’t contain enough detail to make it happen sooner. So, the majority of clashes and conflicts typically occur in the field, after contractors are already on-board. This is the process that is always followed. That is, until AECOM Tishman challenged the status quo with a proprietary process called OneDesign.
