There were issues surround the structural stability of the supporting columns going into the construction. Additional walls and timber members were introduced to improve the structure’s resistance to horizontal shear forces, tying all of the supporting members together into a connected structure. It was also important that these additional walls and timber members are tied into the brick columns during their construction.
(Above) Example of an untied brick wall – the columns had to be demolished and rebuilt to be tied in with the wall. That caused some friction with the bricklayers who were used to simply placing everything on top of each other.
(Above) Timber inserted into the brick columns to improve its structural connectivity on the whole.
