COMPARATIVE COSTS - EARTH MOVING Notes The cost of earth moving and other associated works is dependent on matching the overall quantities and production rate called for by the programme of works with the most appropriate plant and assessing the most suitable version of that plant which will: * deal with the site conditions (e.g. type of ground, type of excavation, length of haul, prevailing weather, etc.) * comply with the specification requirements (e.g. compaction, separation of materials, surface tolerances, etc.) * complete the work economically (e.g. provide surface tolerances which will avoid undue expense of imported materials) Labour costs are based on a plant operative skill rate 3 unless otherwise stated Comparative costs of excavation equipment The following are comparative costs using various types of excavation equipment and include loading into transport. All costs assume 50 minutes productive work in every hour and adequate disposal transport being available to obviate any delay.
