EXTRA SUBSTITUTED AND DEVIATED ITEMS OF WORK
24.1 Deviations
Deviation means deviation in quantities of items, i.e. where there is increase or decrease in the quantities
of items of work in the agreement.
24.1.1 Market rates for quantities deviating beyond certain limit
As per provisions of clause 12.2 of GCC, in case of agreement items, substituted item, agreement
cum substituted items which exceed the limit stipulated in schedule F, of the contract, the contractor
within 15 days of receipt of order or occurance of the excess, can claim revision of rates, supported by
proper analysis, for excess quantities. Engineer-in-Charge shall consider the analysis submitted by
contractor and determine the rates on basis of market rates.
Further as per provision of clause 12.3 of GCC, in case market rates are less than the agreement rates
then in such a case Engineer-in-Charge should give notice to the contractor within one month of occurance
of the excess and should decide the rates based on market rates considering the reply of contractor.
The rates should be worked out by adopting the market rates of material/labour, prevailing at the time
of occurance of excess, in the relevant item as adopted in the justification
24.1.2 Sanction of deviations
Apart from obligation of sanctioning rates under clause 12.2, 12.3 of contract, a proper check is
needed on deviations in quantities on higher/lower side for each and every item. In order to exercise
proper check on deviations, following procedures shall be followed.
(1) Deviations in quantities of individual item up to + 10% of agreement quantities will not need any
prior approval of technical sanction authority and sanction of deviations is not required.
(2) Deviation in quantities of individual item beyond the limit of + 10% but within deviation limit as
specified under clause 12 of the contract, will not require prior approval of technical sanction
authority but total deviation (including initial + 10% ) shall be sanctioned by officers as per delegation
of powers. (Modified as per OM/MAN/175)
(3) If total deviation of quantity of individual item is beyond the deviation limit as specified under clause
12 of the contract then deviations beyond the limit of + 10% should not be made at site without in
principle approval of technical sanction authority. Once in principle approval is obtained, the total
deviations (including + 10%) shall be sanctioned by the officers as per delegation of powers.
(Added as per OM/MAN/175)
(4) In case of deviations occurring in the quantities of substituted/extra items/ deviation in quantity of
any item already sanctioned, then revised sanction should be taken from the competent authority.
(5) Total deviation in quantity of an item shall be sanctioned by one authority only whosoever is
competent to sanction total deviation of the item.
(6) Minus deviation is to be sanctioned on the basis of agreement rate irrespective of deviation limit.
(Added as per OM/MAN/215)
The amount of a deviation statement shall be the sum of absolute value of deviated amounts
of all individual items. (Modified as per OM/MAN/153)
