The distribution of 12 spot heights with a regular 15m spacing covering a square area which is to be graded to form a horizontal plane with the height of 15m. Determine the volume to be excavated from the site. The spot height data are as follows using Grid formula:
To control the elevation of a building, contractors must use or establish one or more benchmarks near the building site. In this example, benchmark A (BMA) is located some distance away from the site and the contractor wants to establish benchmark B (BMB) near the site. Therefore the contractor must: (a) Transfer the elevation form BMA to establish BMB using a technique known as differential levelling (see sketch below) (b) Confirm the accuracy of the work by 'looping' back to BMA or by completing a 'circuit' to another known benchmark - in this case BMC (c) Check the mathematical correctness of the work as well as determine if the work falls within acceptable limits of TIK 3.826 BMA ELEV. = 220,000 |HI = 000022 0.841 2.549 TPI ELEY = HI = DATUM LINE = 0.000 ·257 0.583 BMB ELEV,= HI = 2.681 1.202 TP2 ELEV = HIS 133 BMC ELE/-222,2266
