CHAPTER NO. 12
STONE MASONRY
Notes :(i)
The labour rates include the cost of water, tools and plant, labour and materials for scaffolding and
centring and shuttering wherever required and cost of good earth for mud mortar where required.
(ii)
Unless otherwise stated, the labour rates include the rehandling of materials within 100 metres.
(iii)
The rates include the cost of water. Where the water is supplied free by the Department, rates shall
be decreased accordingly.
(iv)
The labour rates including the cost of dressing stones according to the relevent PWD Specifications.
(v)
The labour as well as through rates for item nos. 12.11, 12.12, 12.13, 12.16 to 12.24, 12.28 to 12.33
are applicable when quarried stone is used. 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. Variations in actual lead in such
cases will be taken care of, by premium/abatement over the schedule rates. 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.
