Bricklayers work on the North end wall. Four cranes are required to complete the roof. The peak of the roof is 65 high. The first two roof supports tied together. A crane holds the second set of roof supports while workers tie them to the other two with purlins.
Workers bolt the pieces together from portable lifts.
Over a third of the roof beams or in place. The roof supports are first bolted to the vertical main support columns before being bolted to each other in the center. Each side of the roof support is put together on the ground out of four pieces and then lifted into place with a crane. The two sections of roof supports must be bolted together once the ends are bolted down. Washing off the exterior brick gets rid of the mortar residue and accumulated dirt and dust.
