FOREWORD
Ever since it's establishment in 1888 by the erstwhile British rulers in India, in the last
125 years of the history of its existence Mumbai Municipal Corporation has catered
to every aspect of the citizen of Mumbai that can be conceived of. Think of Engineer
Victor Tulloch, who through his unparalleled immense efforts conceived the water
supply scheme fetching running over from distance of more than 100 km by
constructing a dam across river Tansa, to feed the population of Mumbai, then only a
few thousands in number. The items have changed with technological advancement
and the works like Roller Compacted Concrete Dam at Middle Vaitarna or numerous
underground tunnels for water supply and sewerage disposal, for example, have
become hallmark of MCGM's dedication to the citizen of Mumbai. The challenges
have always been daunting, nevertheless, always met with.
Every civilization be it 5000 years old Harrappan civilization on the bank of
Sindhu River, or Mumbai on the west coast of the Indian Ocean, require
infrastructure like water supply and sewerage system, storm water drainage system,
road, bridges, etc. and hospitals, markets, recreation centers etc. The exponentially
growing population of Mumbai and the technological explosion in the field of
engineering has made every aspect of contracting of works highly challenging.
M.C.G.M. is one of the largest local self government in the Asian Continent.
In observance of historic traditions of strong civic activism, with the change in time
and living conditions to match with the urbanization, M.C.G.M. has mainly focused in
providing variety of engineering services viz, storm water drain, sewerage, water
supply projects, roads, bridges, solid waste management, environmental services.
Beside this, the Corporation is also providing dedicated services in the Health sector
by establishing numbers of Major and Peripheral hospitals.
To update and modernize the mechanism being used for working on projects
from the stage of conceptualization upto execution, the need was realized to revise
prevailing Schedule of Rates along with specifications which were in operations
with various departments and being prepared individually as per their need and
used to revised at different span of time, resulting into various anomalies. Therefore,
to overcome all these, it was essential to revise the schedule of rates, not only with
simple mechanized revision, major changes to keep up with the pace of urbanization,
civilization, construction techniques / mechanization and voluminous developments
by restructuring items in the schedule as per requirements. This exercise would
-

provide comfort with field requirements and designs and will assist in effective
checks on creation of extra items during execution.
A conscious decision has been taken to keep pace with the changing time
and preparation of Unified Schedule of Rates is the first step forward in this direction.
Since long time, there have been demands made by the stake holders like Municipal
Engineers and Contractors about non-uniformity, anomalies and discrepancies in
various schedules of rates for work contracts of various departments of MCGM.
Every department had its own expertise and way of functioning which got reflected in
its independent schedule of rates, which, however, had no linkage with the fair
market schedules of other departments and resulting into extra items and fair rates.
In place of earlier 9 Schedule of Rates, the Unified Schedule of Rates is an effort &
seeks to rectify the defects, discrepancies and non uniformities which will provide,
not to mention about the ease and accuracy of estimation to the Engineers.
In view of the enormous and voluminous nature of work, keeping time
frame in perspective and above all, to ensure professionalism, the work of
preparation of Unified Schedule of Rates was awarded to the eminent consultants
M/s.Tata Consulting Engineers Ltd. M/s.Tata Consulting Engineers Ltd were directed
to conduct a thorough factual market research for major materials from
stockists/manufacturers/dealers and to study schedules of rates of Govt bodies like
C.P.W.D. and P.W.D. The new Rate Analysis are based on Factual Market research
done by M/s.Tata Consulting Engineers Ltd.
The anomalies in rate are minimized after extensive market research and
collection of quotations from reputed large scaled stockists/dealers, and also after
comparison with rates of CPWD, PWD etc.
The SOR is linked with its comprehensive specifications of basic important
activities so as to have clarity in execution. These specifications follow a chronology
of general scope of the item, material required, processing of material, construction
operation, finishing and mode of measurement.
All the rates are now linked to their detailed specifications and wherever
required, with drawings. Though there are about 12500 items, every item is now
given a Unique Code No. which will eliminate the repetition.
It has been our endeavour to include all the necessary modern materials and
technologies in SOR, for example, the concept of green building, which will go a long
-

way to have control on creation of extra items and fair rates. A salient feature of this
USR is 'Starring of items' specified, categorically which can be used only at certain
works or locations.
Another salient features is 'Dynamic Rate System' which will be based on
study of data base of quantities and bidding prices of awarded contracts on the basis
of which necessary corrections can be applied to the Unified Schedule of Rates at
specified intervals. The MCGM will be now in position to revise the Unified Schedule
of Rates every year after incumbency period of M/s.Tata Consulting Engineers Ltd of
one year, to work with and correct the system as and when necessary.
I hope this 'Unified Schedule of Rates' will be a milestone in civic governance
by MCGM. This self-contained publication shall be of great help and guidance to theofficers engaged in the project work of MCGM.

Star Rating:
In view of ambiguity related to choice of quality or grade of materials and subsequent
items of works to be used at Ward level projects, Centralised projects or Special projects
of and for smooth functioning during planning stage of a project, the new concept of Star
Rating has been introduced for building works depending on the life expectancy of
building, degree of occupancy of building and comfort to the end user. The buildings or
structures rated are as follows:
i. Two Star **- Ward offices and Central dept. Offices, schools, Small
Hospitals, Primary Health Center, Fire Station, Crematorium, Slaughter
Houses, Markets, Swimming Pools, Zoos, Chowkies, Libraries, Staff
quarters and residential colonies, Public Toilets and Water tanks.
ii. Three Star ***- Superspeciality Hospitals , Drama Theatres, MCGM
Mayors and Officers bungalow, Heritage Structures, Head Office and
Engineers Hub.
The items or work not marked as two star or three star are assumed to be
applicable for all the star buildings or structures mentioned above.

1. The rate analysis includes some provisions such as shuttering / centering on a
percentage basis. This has been brought on a rational basis using available data.

concrete works shall be limited to 40mm and that of reinforcedconcrete shall be limited to 25mm unless otherwise specified in
particular items or in drawings.
2) Whenever contractor uses fly ash as part of the cement quantity,
the following formula shall be applied for deduction in the rate of the

Amount in Rupees per Cubic metre of Concrete to be deducted from the
rate of item in the schedule of Rates/Tender :
Notes for R.M.C.
1) Any lead for R.M.C more than 20 km. is on contractors account.
2) R.M.C is required to be unloaded within one hour from plant tosite, hence more than 20kms. Is not desirable.
3) If lead is more than 20kms. The contractor has to establish his own
batching plant near site.

a = Percentage of fly ash used in the concrete mix by the Contractor.
A : Market Rate of cement per bag (50 Kg) in Rupees In Mumbai or
