answers:

1. What is a Bar bending schedule? What the advantages of BBS?

Ans:
Bar bending schedule is a way of organizing rebars for each structural unit, giving detailed reinforcement requirements, it is referred as the BBS and it contains bar mark, diameter, length shape and weight. It is the process of cutting and bending reinforcement steel bars according to the drawing
Preparation of the bar bending is one of the final programs where certain amount of calculation is carried out with the aid of the computer program, this helps the site engineer estimate required quantities of the reinforcement.
Advantages:
• Better estimation of the reinforcement used in the structural concrete member
• Helps in procurement of reinforcement steel and in better stock management
• Exact estimated quantity is determined
• Because of the bending and the cutting done transportation will be easy
• It will be easy for the site engineer for the check the work done.
• Billing can be done easily.

2. Usage of Bar bending schedule in construction projects?

Ans:
Bar bending schedule in construction projects is used for:
• Bars should be grouped together for each structural unit
• The bars should be listed floor by floor
• For cutting and bending purposes schedules should be provided as separate A4 sheet
• The bars should be listed in the schedule in numerical order.
• The bar mark reference on the label attached to a bundle of bars refers to a group bars of defined length, size, shape and type used on job.
• BBS helps to keep track on the steel fixers and labours on type and number of bars required for the project.

3. Explain in detail the step-by-step procedure for a Bar bending schedule?

Ans:
Step-by-step procedure for a Bar bending schedule is:
I. Identification of the members
Refer all the bar mark in the structural drawing and list down all shapes of the bars with the diameter of the respective member beside.
II. Count the number of bars
Count all different shapes of bars that is required for the structure as given in the drawing by doing the respective calculation include both the main reinforcement and distribution reinforcement calculations.
III. Calculate the length of the reinforcement bars
Where, length of the bar = length of the concrete member- (2*cover) + development length.
IV. Calculate the unit weight of the reinforcement bar
Unit weight of the bar= volume of bar * density of bar (7850Kg/m^3)
Unit weight of the reinforcement bar with dia D = D^2/162
V. Calculate the weight of the particular shape of bar
Weight of reinforcement bar= number of bars * length of bar *unit weight of bar

4. What is Vaastu Shastra? Write briefly the Vaastu shastra requirement/ needs to be followed for a house project in detail?

Ans:
Vaastu shastra is the ancient Indian science of architecture and acts as the guideline to design your home in the way to enhance the positive energy. A good home needs to radiate the right kind of the energy. A person dwelling in the house comes under the influence of a specific energy field.
Vaastu shastra need to be followed for house project are:
• Shape: rooms should be square or rectangle in shape
• Room basics: it should airy, well, bright and clean.
• Centre of the house should be empty space
• Heavy furniture and stairs should not be kept in the south-west direction.
• Avoid keeping plants and water features in the bedroom.
• Dinning table should be near to kitchen and not near main door.
• Mirror facing the bed is strictly not allowed.
• Kitchen: south-east is best and north-east should be avoided.
• Staircase: south west is best and north east to be avoided
• Toilet: north west is best and north east to be avoided.
• Master bedroom and guest room south west is the best
• Living room north west is the best
• For over head tanks west is the best
• Underground tanks north east is best and south west to be avoided
• Main door should be stronger and bigger than other doors in the house and made of the superior quality of the wood (teak wood)
• Main door should be inward and avoid the creaky sounds
• Unwanted things should be kept out of the main door.
• Main door should be north or east facing
• Avoid painting the main door black and placing of animal statues near the door.
• Living room should be cluster free
• Should face east north or northeast
• Electronic appliances should be installed in the south east section of the living room.
• Mirror in the living room should be on the north wall.
• Bedroom in south west direction is encouraged and avoid in north east or south east.
• In bedroom, avoid having the painting depicting water of a fountain
• Bed should be placed in south west direction
• Avoid overhanging beams in the room.
• paint in bedrooms should be neutral or earth shades
• use solid wooden beds instead of hallow cast iron beds
• pooja room is placed in east or north east direction
• in pooja room create a sacred altar and decorate with the candles or incense sticks
• keep water sink away from gas stove
• fridge should be placed in south west corner
• kitchen should never share a common wall with washroom nor face the washroom
• hanging book shelves are best avoided
• courtyard should be perfect and clutter free
• in the place of courtyard there should not be kitchen, bathroom, pillar/beam that attracts the negative energy.

5. Write briefly about the list of drawings that is mandatory to be provided to the site and also a brief note about the important basic details that need to be covered in the drawing to ease the mode of construction?

Ans:
list of drawings that is mandatory to be provided to the site are:
I. centre line drawing
• it is used for the marking of the columns at the site during first stage where soil is excavated for the footings
• it contains all the grid positions and column dimensions and numbering (provided outside of column)
• it is a important which is first issued to the site.
• Gird to grid distance and structural notes and the legends are mandatory
II. footing and column layout with reinforcement details
• it shows the size and dimensions of the footing from centre of the columns and also with reference to the gridline
• here we can check weather there is a footing clash from which we can manage by altering the dimension is required directions so there is no clash obtained
• Gird to grid distance and structural notes and the legends are mandatory
III. column schedule with reinforcement details
• typical footing layout details are provided
• reinforcement details of the column is required
• for respective columns provide the column size and column reinforcement detail and stirrup details is also to be provided
• footing also has to be categorised
IV. plinth beam layout with reinforcement details
• provide the column that are connected to the soil at the plinth level
• specify all PB footings which describes the reinforcement of the plinth beam
• numbering and grouping of the plinth beam are important step.
• 2 bars at both top and bottom reinforcement are mandatory
V. first floor beam layout with reinforcement details
• any details of the floating column
• where the typical beams connecting the columns
• beam numbering and grouping is shown
VI. first floor slab layout with reinforcement details
• provide the location of the sunken slab with its sunken thickness
• floor beams and slab dimensions are provided commonly
• level difference if required should be presented
• reinforcement details of the slab is must
• crank position should be indicated

• It covers the area of the lift pit area describing the thickness of the RCC wall and waterproof wall
• And provision of the lintel beam is mandatory
• Sectional view of the lift pit is also important
• Lift pit and head room should be in same position
• Load should be considered before the liftroom
