Hi Graham,

The offset of the axis of the first and second pyramid is almost identical at 3-6 minutes west of north. The effect of this difference on the siteplan length is negligible. The axis of the third pyramid is around 12 minutes east of north. This would have an effect on the dimensions of the siteplan, but the effect would depend on how the site of the third pyramid was surveyed, in relation to the other two.



The West wall of the workman's barracks has approximately the same axis as the third pyramid. It is also closely aligned with the third pyramid, suggesting that it may have been used as the survey line for the west side of the overall site. If so, the difference between the axis of the workman's barracks and the third pyramid in relation to the first and second pyramid would affect the EW site length but the affect on the NS sitelength would be negligible. The different axis of the workman's barracks and the third pyramid is greatly exaggerated below to illustrate the point.



This also supports the idea that in addition to a NS sitelength of 1732 the EW sitelength was intended to be 1414.2 or the square root of two, because the axis error of G3 would cause the EW sitelength to be longer than it was supposed to be if the site was surveyed as suggested by the diagrams above. This axis alignment issue and some other aspects of the overall siteplan are discussed on one of my webpages:
