When work is built with small boulders or with stone obtained by breaking large boulders, the above rates will be increased by Rs. 30.00 per cum on account of extra labour involved in dressing. (vi) The through rate of the stone masonry, include the cost of stone at the site of work irrespective of the distance from the source, but stone masonry will normally be constructed in such area, where stone is available locally, or in the vicinity of the site of the work.

Where, however stone is not available near at hand but has to be brought from long distances, item of stone masonry should not be specified, and if, some work has to be constructed in stone due to very special reasons, extra provision for carriage of stone should be made in the estimates. (vii) If pumping is required in wet stone masonry work, it will be done departmentally.
