Assume one work is awarded to a contractor on item rate basis. During the execution of work, the necessity arises to do some works which are not given in the contract, but the contractor has been requested to carry out such works and payment will be made after supplemental rates and agreement are executed
This is extra. work
Example Providing stainless steel handrails instead of aluminum handrails
Here extra work is provision of stainless steel handrails
During the execution of foundation work, the quantity given in the agreement is exceeding due to actual type of soil
Here additional quantity of earthwork, filling, RR work will be coming which are needed
Usually in the agreement itself it will be mentioned that the rates are applicable up to 5% more or less besides quantity

The affect of the construction of weir or barrage on the regime of the river are as follows :-
– The velocity of flow of water reduces.
See less– Sedimentation can be occured which makes the height of the flow constant.
– Fishes and other water animals migrations can be restricted.
– Increases the flow height for a short duration.
– Because of the barrier the particles settle down near it.
