Variations among rough cost and detailed cost

This construction video tutorial sheds light on definition of rough cost and detailed cost and variations among them.

Rough cost estimate plays an important role in construction. If there are huge variations among the rough estimate and the cost of construction that may impact the decision to begin a project. If the rough cost is too high, project may be left devoid of creating its detailed estimate.

Alternatively, if the rough cost is too low then project may begin but once the detailed estimate is made, design and drawings are cancelled because of shortage of fund.

Detailed cost estimates should be made cautiously. These briefly estimate the cost of different items work that set ups the entire project. Detailed estimates are accomplished once the detailed working drawings are made together with specifications. If any error occurs in rough cost estimate, then it will provide great influence in detailed cost estimates.

In this video, example is given for a plinth area having 400 sft. Plinth area belongs to the built up covered area that is computed at floor level of the basement or of any story of building.

The rate is charged as Rs. 400 per square feet and it includes 8% of electricity, 4% of water, 4% of sanitary, 4% Gas etc.

Detailed cost includes earth work, concrete work, brickwork in foundation, DPC (damp proof course), brickwork concerning superstructure, cement plaster, white washing.

How to generate bar bending schedule for the floor columns

This construction video will teach you how to produce bar bending schedule on the basis of the section drawing of floor column from ground floor to first floor.

Details of section drawing:

The height is given from ground floor to first floor as 3000 mm or 3 meter.
There are stirrups, main bars, beam and over lapping for column.

The overlapping for the column from 1st floor to 2nd floor is given as 50D.
The actual length of the column is given as 2543 mm i.e. stirrups will come up to this.

Stirrups Details:
The breadth of the column is 300 mm
The depth of the column is 450 mm
The cover is taken 40 mm on both sides
There are 6 main bars with 12 dia meter
There are stirrups of 8 mm with 100 mm spacing center to center

Based on the above, the calculation is made. Watch the following video to get the detailed calculation process.
