Raising the LCLS Office Building

Last Wednesday and Thursday, in only two working days, construction crews assembled the exterior of what will be the new office building for the Linac Coherent Light Source. After receiving final safety instructions Wednesday morning, workers were cleared to begin erecting 22 two-story concrete panels that make up the exterior walls of the building.

One by one, the crew used a crane to lift the panels—all poured on site—and place them upright in their designated locations. The first handful of panels were the easiest to place since they were created exactly adjacent their destinations. Due to space constraints, the other panels were slightly farther away, which meant the crane had pick them up and move them slowly and carefully to their spots. The crew had all 22 panels in place by Thursday afternoon, well ahead of the predicted rain.
