FOREWORD

In the current era a lot of people are facing difficulties to build house, as they have a piece of land and sufficient funds for construction purpose, as some have a

knowledge and experience but can't spare time and some have no knowledge I experience of construction work. Some are fed off / annoyed due to behavior and

performance of builder / contractor and work is held/delayed.

In our opinion the simple reason of above is that both the parties had not shared their thoughts ideas regarding specification of work to be executed, utilities,

accessories, fixtures, to be used before signing the agreement.

Mostly they discuss the rates and finalize the agreement.

Disputes always occurs while execution of work regarding the matters which were not discussed before and work is held/discontinued and sometime increases

up to this extent the matters are referred to the court and settled which is just wastage of time and money. To avoid such future disputes we provide asspecification of material', utilities, fixtures etc to be used in construction of building so that respected client should study it thoroughly and practice will be

helpful for assurance of highest possible quality standard to the entire satisfaction of our respected Clients.

AL HASSAN has a team of professionals, construction, architecture, planning and execution engineer to help you in providing a highest possible quality

constructed house/building for completion in a scheduled time frame at competitive rates.

1. SPECIFICATIONS

What is Specification? Specification describes the nature and the class of the work) materials to be used in the work, workmanship etc. which is very importantfor execution of the work. The cost of a work depends much on the Specification. Specifications should be clear, and there should not be any ambiguity

anywhere. From the study of the specifications one can easily understand the nature of the work and what the work shall be. The drawings of a building or

structure show the arrangement of the rooms and various parts, and the dimension, length, breadth and height with very brief descriptions of different parts.

Drawings do not furnish the details of different items of work, the quantity of materials, proportion of mortar and workmanship which are described in

specifications. Thus the combinations of drawings and specifications define completely the structure.

During writing specification attempts are made to express all the requirement of the work clearly and in a concise form avoiding repetition. As far as possible,

the clauses of the specification are arranged in the same order in which the work will be carried out. The specifications are written in a language so that they

indicate what the work should be.

Specifications depend on the nature of the work, the purpose for which the work is required, strength of the materials, availability of materials, quality of

materials, etc.

2. TYPES OF SPECIFICATIONS .

General specification or Brief specification.

Detailed specification.

2.1. GENERAL SPECIFICATION OR BRIEF SPECIFICATION .

General or Brief specification describes the nature and class of the work and materials in genera' terms, to be used in the various parts of the work; from the

foundation to the superstructure. It is a short description of different parts of the work specifying materials, proportions, qualities etc. General specifications

provide general idea of the whole work or structure and are useful for preparing of the estimate.

For general idea, the general specifications of different class of buildings are given below. These will of course very accordingly to the necessity and type of

works.

2.2. DETAILED SPECIFICATIONS:

The detailed specification is a description to express the requirements in detail. The detailed specification of an item of work describes the qualities and

quantities of materials, the proportion of mortar, workmanship; the method of preparation and execution and the method of measurement. The detailed

specifications of different items of work are prepared separately and describe what the works should be and how those shall be executed and constructed.

Detailed specifications are written to express the requirements clearly in a concise form avoiding repetition and ambiguity. The detailed specifications arearranged as far as possible in the same sequence of order as the work is carried out. The detailed specifications are prepared properly to help in execution of the

work.
