1. ESTIMATE
An estimate is the anticipated or probable cost of work and is usually prepared
before the construction is taken up. It is indeed calculations or computations of
various items of an engineering work.
2. QUANTITY SURVEY
It is the schedule of all items of work in a building. These quantities are
calculated from the drawing of the building. Thus quantity survey gives
quantities of work done in case of each items, when priced gives the total cost.
In short, quantity survey means calculations of quantities of materials required
to complete the work concerned
3. SPECIFICATIONS
Detailed specifications gives the nature, quality and class of work, materials to
be used in the various parts of work , quality of the material, their proportions,
method of preparation, workmanship and description of execution of work are
required.
4. RATES
The rates of various items of works, materials to be used in the construction and
the wages of different categories of labor (skilled and unskilled) should be
available for preparing an estimate. The cost of transportation charges should
also be known. As far as possible sanctioned “Schedule of Rates” shall be
followed or the rates may be worked out by the “Analysis of Rates” method.
5. SITE PLAN
It is the plan drawn for a particular construction showing its position with
respect to approaching roads, main bazars, markets and other permanent features
in a populated area. It shows the location of the area under construction with
respect to the other areas and on it generally the names of the owners of areas or
property holders adjoining to it are also denoted. North line is also clearly
marked on it.
6. LINE PLAN
Line plan can be defined as the plan of a particular construction simply showing
main features with the help of the single lines of different portions of
