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


3/81

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


4/81

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.

A.M.C. (Project) Municipal Commissioner

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.


10/81

C. SALIENT FEATURES OF SOR FOR ROAD AND BRIDGE WORKS

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.

minimum grade of structural concrete as recommended by IRC / MORTH for severe

exposure has been adopted.

Notes: Applicable for all cement concrete items in the BRIDGE

Schedule.

1) All concrete shall be machine mixed and consolidated and I or

compacted by vibrators. The maximum siize of aggregate for plain

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

item.

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
