ONE WAY TO MEASURE A JOB.
Find the surface measure of the entire job, including all edges and projections, and estimate how much it is worth per yard, on the basis that it is all plain work, easy to get at. Next we will proceed by what we may call special measurement. Suppose the cornice measures 60 yards, and is finished with blocks, moulded panels and brackets, and we estimate that the cost of painting it will be three times that of a plain cornice, hence we will add two measures or 120 yards to the general or first measurement. Next, suppose each window and casing measures three yards, and there are 20 of them to be trimmed in colors, we estimate the work of painting them double that of plain work; hence we add to our special measurement 60 yards. If there is a cupola high and difficult to reach we estimate that it will be worth double the cost of painting ordinary work to do it. Say, it measures 50 yards, we will add 50 yards to the general measurement, and so we will go on until we have taken in all parts of the work which will cost more than ordinary plain work.
To illustrate: The building measures 600 yards, and as plain work we estimate it worth twenty cents per yard to paint it. We amount our special measurement which we will say adds up to 300 yards, which added to the 600 yards general measurement, makes 900, which at twenty cents per yard, makes $180. The same system may be used inside.
