        The staircase shaft: Precast stairs will be erected 
        into the shaft to form the completed staircase. The workers inside the 
        shaft are forming a chase using hand chisels for the future connection 
        of the reinforced concrete landing. The steel link bars, already in place 
        in the concrete wall, will be recovered. The landing for the staircase 
        will be constructed in situ later
