The practice of most of the companies engaged in this class of work is to make a fixed charge per square yard for the pavement, including the concrete but excluding the excavation, and they also guarantee to keep the pavement in repair free of charge for one or two years, and then for so many years after, at so much per yard per annum.
About 14s. per square yard is generally the first charge for constructing, and 1s. per square yard is the annual charge for maintenance.
Upon the subject of cost the following tables[83] may be useful.
