The panels in the corridor

The exhibition panels arrived in numerical order, but the mounting plan identified them only by title. Two titles had been shortened on the printed panels, so their position was not obvious. The corridor's fire door needed to open fully, ruling out one planned location. Another section of wall contained a socket that staff still needed to reach. The adhesive supplied with the panels would not hold on the rough surface beside the stairs. We revised the plan on the floor before attaching anything permanently.
