Union Pacific Depot
The Union Pacific Depot is more than a hundred years old. Its age and the methods by which it was constructed pose settlement challenges, and variation in the construction materials used resulted in different settlement and compression behaviors. FOCUS was tasked with monitoring the building’s settlement and, to do so, placed 22 wall stations, each with three different vertical stations, and eight independent floor stations throughout the building. The stations are then relayed to a network of six reference stations mounted to stable structures and utilities. Measurements from wall and floor stations are taken in relation to the reference stations to detect minute movements in the structure. This process requires extreme attention to detail to ensure that the measurements are accurate and consistent. FOCUS’s skill at this process made it possible to detect unique behavior in the building that could not have been precisely quantified otherwise.
