On the other hand, in walls A-Band D-E, this measurement seems to be somewhere around31 sun (939mm), but the minimum value, maximum value,and mode vary widely and size adjustment seems to havebeen made by a combination of different brick modules.Regarding pilasters, they appear to have been plannedwith a three brick unit length (= 6 brick unit short-end width)to be 23 sun (697mm), which was derived by adding a widthof vertical pointing to the actual measurements of pilasters A,B, D, and E. The width of vertical pointing was estimated tobe 0.3 sun (9mm) through actual measurements.Although standards for neither brick size nor width ofpointing are given in the construction specifications, inthe construction report, descriptions of mortar are givenas follows:“A ratio of cement 1, lime 2, sand 5 is to beemployed for mortar and (bricks are to be) laid with pointingof 3 bu ;”thus, pointing was set at a width of 3 bu .To maintain the width of mortar pointing and at the sametime change the brick module, it is necessary to differ thesize of bricks for making adjustments.
