The full scope of labor and coordination required to install an exhibit at the start of a show and dismantle it at the close. I&D encompasses unloading freight, assembling structural components, installing graphics, connecting electrical and A/V systems, placing furniture, and performing all finishing work during move-in, then reversing the process during move-out. I&D is typically the largest labor cost in a show budget and requires careful scheduling, experienced supervision, and coordination with the general contractor and venue.
