520			_aLooks at the measurement of rock when defined as a hard material in a contract document. The current definition has evolved into a material so designated in the Preambles to the Bill of Quantities and/or material which requires the use of blasting, breakers or splitters for its removal but excluding individual masses less than 0.20 cubic metres. Outlines the three options for the designation of hard material as designated strata, designated deposits with limits shown in the drawings and existing pavements, footways, paved areas and foundations. Concludes that in order to make the system of measurement of hard materials work the measurer should determine the need for hard material excavation, define what is considered hard material in accordance with the MMHW/MMRW, properly consider hard material in the contract documents and reflect the true cost of hard material excavation in the cost estimates.
