Excavation and Earthworks. (a) The units of measurements shall be: (i) Bulk excavation and filling cubic metre (ii) Excavation, filling and compaction for pipelines metre (iii) Excavation in rock, extra over (i) and (ii) above cubic metre (iv) Preparation of surface, trimming of slopes, (b) pitching, soiling and grassing Method of Measurement square metres (i) Earthworks measured by the cubic metre. The measured volume shall be the net-in-situ volume obtained from the difference between the lines, levels and profiles of the ground or rock surface agreed with the Engineer before excavation is commenced and the lines, levels and profiles as shown on the Drawings, or as may be ordered by the Engineer as necessary for the Works. Where the Drawings do not indicate the profiles of the excavation, the measured volume shall be the volume of the voids that would be formed if the completed structure, for which the excavation is performed, were to be lifted vertically out of the ground. (ii) Pipelines measured by the cubic metre. Where excavation for pipe runs is measured in the Bill of Quantities by the cubic metre then the measurement shall be taken as the vertical depth from the commencing surface down to formation level and the width of the excavation as 400 mm wider than the nominal internal diameter of the pipe or as directed by the Engineer. (iii) Pipelines measured by the metre Depths used for classification in the Bill of Quantities shall be measured from the commencing surface to the inverts of the pipes. (iv) No measurement will be taken for material excavated beyond the limits and levels specified above.
