An elevation must be established on a bench mark on a hill that is 2594.034 m from the nearest bench mark below. The surveyor decides to use a total station that has a stated distance measuring accuracy of ±(3 mm +3 ppm), and a vertical compensator accurate to within ±0.3__. The height of instrument was 1.68 m with an estimated error of ±5 mm. The prism height was 2.000 m with an estimated error of ±1 mm. The single zenith angle is read as 85_26_ 06__. The estimated errors in instrument and target centering are ±2 mm. If the elevation of the occupied bench mark is 106.579 m, what is

(Assume that the instrument does not correct for Earth curvature and refraction.)
