This specialist module allows the rapid entry of Surfacing Items to be added to an Estimate. The calculator allows materials and gangs to be selected, with the quantities of the materials (in tonnes) calculated from material density, % compaction, thickness, % waste and superage. These calculations are then applied to the total Item quantity (measured in square metres) and a rate build-up produced as a combination of the materials, labour, plant, gang, transport costs etc. The calculator may be used add several surfacing elements to the same Item, such as sub-base, main and wearing courses etc. The calculator may be used to change any element of the calculations after they have been initially created.
