Abstract:
The estimated cost of a concrete road in a given location may be made in one of 3 ways: first, by making an estimate per mile, based on what other roads have cost under approximately the same construction conditions; second, by itemizing each detail after full surveys have been made, grade lines established and costs of materials and length and character of haul obtained; and third, by the conctractor making (a) a scientific guess based on carefully prepared unit prices obtained locally, using all available information gathered on the ground, or, (b) an estimate rendered with the idea of taking a chance that no one else has cut lower on the engineer's estimate and that the engineer has been somewhat liberal in preparing said estimate.
