Building Drawing Introduction

Building Drawing Introduction Drawing is the language of engineers. An engineer must be well conversant with drawings. Drawings represent reduced shape of structure and the owner will be able to see what is going to happen. Drawings are prepared as per the requirements of owner. In case of public buildings, the functional aspects are studied and accordingly the drawings are prepared as per recommendations laid down in National Building Code (N.B.C) or as per Indian Standard specifications. Any modifications like additions or omissions can be suggested from a study of the drawings before actual construct the structure accordingly. In case of public buildings or any other civil engineering works, it is essential to work out different construction of the structure is started. Drawings provide a language with specific data to Architects, Engineers and workmen at the site to parts and different views are essential so that the approval of work…

Order of construction | Item of work | ITEMS OF WORK While preparing detailed estimate of a building it is necessary to split the entire building into different items preferably in the order of its construction. e.g. The load bearing structure to be constructed may be split into following items of work in the order of its execution as: Site clearance. Excavation for foundations. P. C. C. in foundations.  masonry in foundations.  C. R. masonary in plinth. Damp proof course at plinth level. Plinth filling with hard murum. Brick Work (or stone masonary) in Superstructure. Providing and fixing door and window frames. Lintels over openings. Flat R.C.C. or sloping roof. External and internal plastering and pointing. Providing and laying flooring. Door and Window shutters. Water supply and sanitary arrangement. Electrification. The quantities of the above items of work are calculated from the relevant drawings (i.e. plan, elevation, section and foundation…

TYPES OF ESTIMATES The estimates are broadly classified as (i) Approximate Estimates, and (ii) Detailed Estimates Before a detailed estimate of the proposed work is to be taken up, it is necessary to prepare its approximate estimate. An approximate estimate gives the approximate cost of the work and is prepared on the basis of cost of the similar works carried out in the past. Such an estimate is required to obtain administrative approval in case of Government works. Once the work is administratively approved by the Government, a detailed estimate is worked out. A detailed estimate is prepared after its complete set of drawings are ready. The quantities of various…

Introduction to Estimating and Costing Before any engineering project is to be constructed, it is necessary to know its estimated cost to ascertain whether the required funds can be made available for its completion or not. If the funds available are more than the estimated cost of the work, the execution of the work can be started. If, however, the available funds are less than the estimated cost, then either the work may be executed in parts or its specification can be altered to bring down its cost within the available funds. The actual cost of construction (which will be known after its completion)…

There are some differences regarding the method of measurement among the State Government departments. But the method introduced by the Indian Standard (I.S.) is legal and basic document for removing ambiguities and settling all the disputes for making payment to the contractors.

DEVELOPMENT OF FLUID MECHANICS

Fluid mechanics is that branch of science which deals with the behaviour of the fluids at rest as well as in motion. In general the scope of fluid mechanics is very wide which includes the study of all liquids and gases. But usually it is confined to the study of liquids and those gases for which the effects due to compressibility may be neglected. The gases with appreciable compressibility effects are governed by the laws of Thermodynamics which are however dealt with under the subject of Gas dynamics. The problems, man encountered in the fields of water supply, irrigation, navigation and water power, resulted in the development of the fluid mechanics. However, with the exception of Archimedes (250 B.C.) Principle which is considered to be as true today as some 2250 years ago, little of the scant knowledge of the ancients appears in modern fluid mechanics. After the fall of…

DEFINITION OF  FLUID what is fluid and its classification A fluid may be defined as a substance which is capable of flowing. It has no definite shape of its own, but conforms to the shape of the containing vessel. Further even a small amount of shear force exerted on a fluid will cause it to undergo a deformation which continues as long as the force continues to be applied. A liquid A liquid is a fluid, which possesses a definite volume, which varies only slightly with temperature and pressure. Since under ordinary conditions liquids are difficult to compress, they may be for all practical purposes regarded as incompressible. It forms a free surface or an interface separating it from the atmosphere or any…
