Set up over point 2 RL 99.70
sight point 1 the TBM RL 100.00
TS reading for point 1 TBM 100.007.

Need to set out finish floor level point for earthworks fellows of 98.85.

If you first set out floor level 98.85 using point 2 level as assumed correct station height and make a mark.

What adjustment up or down do yo make to the set out point mark to ensure floor level mark is really 98.85, based on point 1 TBM that is actually 100.00 ?
