Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

What is Specification?
Introduction
A Specification is a specific description of a particular subject. An
engineering specification contains detailed description of all
workmanship and materials which are required to complete an
engineering project in accordance with its drawings and details.
The technical drawings of a structure will show the proportion and
relative positions of the various components of the structure.
Many a time it is not possible to furnish the information on the
drawings, regarding the quality of materials to be used and the quality
of workmanship to be achieved during construction, due to Shortage of
space.
This data regarding the materials and workmanship is conveyed in a
separate contract document which is known as the “Specification” for
the work.
Thus the drawing with the specification “will completely define the
structure.” The “Specification” is furnished separately along with
drawing and is an essential part of all engineering contracts.

Necessity of Specifications
The cost of an unit quantity of work is governed by its
specification.
Specification is an essential contract document and is
required for Arbitration or court cases.
The necessity of specification is to verity and check the
strength of materials for a work involved in a project.
Specification is necessary to specify the equipments,
tools and plants to be engaged for a work and thus
enable to procure them beforehand.
A work is carried out according to its specification and
the contractor is paid for the same, Any change in
specification changes the tendered rate.

This also specifies the workmanship and the method of doing
the work. Thus specification of work serves as a guide to the
supervising staff of the contractor as well as to the owner to
execute the work to their satisfaction.
As the rate of work is based on specification a contractor can
calculate the rates of various items of works in a tender with his
procurement rates of materials and labour. Thus tender paper
without specifications of works is baseless, incomplete and
invalid.
Specifications of work are required to describe the quality and
quantity of different materials required for a construction work
and is one of the essential contract documents. Thus a
contractor can make a programme to procure the materials
required for a project and the owner can check the quality of
materials conforming to the specification avoiding dispute with
contractor.

How to write specification?
Description of materials:
The quality and size of materials required to do an item of work shall
be fully described for checking up at site according to the bindings
provided in the specification. The proportion of mixing or treatment
of materials if required before use shall be clearly described.
Workmanship:
Complete description of workmanship, the method of mixing to the
proportion, the method of laying, preparation of base or surface,
compaction, finishing and curing etc. specifically applicable to the
item of work shall be clearly stated in different clauses.
Tools and plants (T.&P.):
The tools and plants to be engaged to carry out a work shall be
described. The method of operation and by whom to be supplied
shall be stated.

Protection of new work:
The method of protection of new works against damage or the method
of curing if required, the test of completed work if necessary shall be
described in separate clauses.
Expression:
While writing a specification Endeavour shall be made to express the
requirements of the specification clearly and in concise from
avoiding repetition and unusual works. The style of tense shall
remain same throughout. The sentences shall be short, simple and
concise. As the specifications are the legal documents, terms such as
suitable, proper used and works having more than one meaning
shall be avoided.
Clause of the specification:
The clauses shall be arranged in the order in which work shall be
carried out.

Types Of Specifications
General specification
i. In general specifications, nature and class of works names of
materials and proportion that should be used in the various items
of works are described.
ii. Only a brief description of each and every item is given. It is
useful for estimating the project.
iii. Without going through the lengthy detailed specifications,
general information for the quantities of materials, nature and
class of work can be known from the general specifications, but
they do not form part of the contract document.

Detailed specification
i. The detailed specifications form a part of the contract document.
Detailed specification for a particular items specify the qualities,
quantities and proportions of materials, and the method of
preparation and execution for that particular item of work in a
project.
ii. The detailed specifications of the different items of works are
prepared separately and they describe what the works should be
and how they shall be executed and constructed physical, chemical
and electrical tests if any requires for the finished work to ensure
the desired strength or quality are specified in the detailed
specification.
iii. They of machinery, equipments and special tools and plant their
methods of operation when involved during execution are
described in the detailed specification.

iv. The method and duration of protection of finished works as
required are specified in the detailed specification.
v. This also specify the involvements and responsibility for
auxiliary works, incidental damage etc.
vi. During execution of the original work. While writing the
detailed specifications the same order of sequence as the
work is to be carried out, is maintained.
vii. Engineering departments maintain detail specifications for
different items of work those are followed to carry out work.

Bill of Quantity (BOQ)
Bill of Quantities or Schedule of Quantities-
• This is a complete list of all items of work involved in connection
with the estimate for a project with the description, quantity and
unit of rate against each item of work.
• These are filled up in a tabular form similar to the abstract of
estimated cost but the rate and amount column remain blank.
• The bill of quantities when multiplied by the corresponding rates
of the items and totalled, gives the estimated cost of the project.
Such a bill of quantities is provided in a tender form for item rate
tenders.
• Contractors put up their own competitive rates and calculate the
totals to offer their estimated amount to complete the whole work.
• The bill of quantities is also required to calculate the quantities of
different materials required for the project.
15. Eng. Kishor K. Ade
Schedule of Rates
Schedule of Rates-
• To facilitate the preparation of estimates, and also to serve as
a guide in setting rates in construction with contract
agreements, a schedule of rates for each kind of work
commonly executed (viz. works, materials, wages of labour,
transport etc.) should be maintained by different engineering
departments or authorised organization and kept up to date.
• This is prepared on the basis of the rates prevailing in each
locality including the cost of transport and profit. All rates
should be inclusive of labour, materials and unless specifically
mentioned otherwise should include all charges like tool, ferry
charge, local charges, income tax, sales tax, Royalties etc.
• As many have to be incurred by the contractor for getting the
respective items of works executed to proper

Order and complete and finish.
• Unless specifically mentioned otherwise in the description of
the item itself, no extra charges should be paid for scaffolding
(including stage scaffolding), centering shuttering, curing etc.
• and the rates are to be deemed to be inclusive of the same. In
the schedule necessary analysis of the rates for the varying
conditions should be provided.
17. Eng. Kishor K. Ade
Contract Documents
Contract Documents-
• When a work , other than a petty work which is to be executed
under the work order system, is proposed to be given out on
contract, the Engineer-in-Charge (on behalf of the owner)
prepares ‘contract documents.’
• Both the parties entering into a contract must put their signatures
on each page of the contract documents and, in the case of sealed
contract, their seals under each signature.
• Special care shall be taken to see that all corrections, additions,
alteration, omissions, over- writings or slips attached to the
agreements are duly signed or initialled by the contractor and the
accepting authority.
• In case the contractor fails to sign the above particular it may
result in disputes and disregarding claims of the Department.
