Variation to Work

Hi All,

In one of the preceding post I read this,



"It is very clear that an activity maybe critical at some junction in the timeline, however, as work progress, the said activity may lost criticality."



IMHO a critical activity in critical path remains critical until it is completed,during the progress of work. it may become non-critical if and when major changes introduced to the scope of work thereby and some other activity becomes critical.

I may be missing the point here, can someone enlighten me on the possible scenario of the statement in quotes.





cheers

Dear Rohit,



If it is not mentiones in the tender drawings, but if in the TS(technical specification) the activity description is given with the gravel. You have to do the work without any additional time n cost.

But on other hand, if it is not in a tender drawing, but shown in the IFC drawing and not mentioned in TS, you can ask for additional time n price for the same as it ll be treated as additional item.

Regards,

cheers

I hate to rain on your day fellas...but the Contract may not say that a "substitution" of material is classed as a variation. Many forms of FIDIC are amended to remove key qualities that prevent certain types of ’change’ being recognised as a reason for entitlement.



Firstly, Rohit, you need to check the obligation under the Contract Document (T + C’s) and then look at the Variations clause to determine what it say’s.



The ’obligation’ of the Contractor (I assume that’s you Rohit) may be for a thickness of material (say) and thus the change in material itself may not be considered as a ’change’ to the Contract performance. This may be one reason for the Engineer (is that Engineer with the POA or just the PM ?) to suggest it was a general requirement.

you had a Revised Design, according to this new design we were supposed to place Gravel.Gravel was not shown in the tender drawings and in the schedule activity duration is based on the work without Gravel.







When you asked for additional time for placing this Gravel, Engineer said this is the General Requirement of the activity and hence no additional time.



Please be informed that all the contract documents are completary and if any requierments mentioned in any of the contract documents so it seems to be part of the original scope of works.

so please restudy the contents of specifications,BOQ,Drawings tender clarifications >>>>>>>>>>etc .

if you did not find any thing regarding the said addetial materials then you have to answer as an experiance contractor, why you did not asked the client or the engineer during the tender stage.

i can understand from the engineer comment that this aggregate materials is commenly used in this case for example it is practice in our sepecification that all pipe lines shall be provided with granulare mateials deb and surround the pipes and to be enclosed in geotixtile filterfabric so it is a general requirements for laying of the pipelines wither it mentioned or not in the contract drawings and if not mentioned the contractor definetly will raise this point during the tender stage otherwise it will be his reposibility to do the works to the best quality without egnoring the general requirements which may not necessary to be mentioned in the contract documents.

So Rohit,



In the event you are really justified for extension of time, then, you have to document periodically on how the activity becomes critical.



It is also very important to take note when this may become non critical.



Reveiw the "Marant Case" forwarded by our good and reliable friend Mr. Andrew.



It is very clear that an activity maybe critical at some junction in the timeline, however, as work progress, the said activity may lost criticality.



In other words, there may be another activity that is more critical than this activity.



So why insist and sour relationship? For as long as you did the best ever pratice in PROJECT CONTROL then you can move on and enjoy Planning.

Rohit,



All you have to do is explain to him your position that this is a variation due to re-design from rip rap to concrete.



Your entitlement for extension of time may be reasonable or may be not reasonable.



So, all you have to do is submit a letter telling him your entitlement as per contract that this event will be demonstrated as impacting on the schedule as worl progress.



So just do what an effective planning engineer must do.



Cheers,

Charlie

He is bluffing. He thinks if he says it with a straight face he intimidate your outfit into picking up the tab for the extra cost and the risk for the extra time, and cover for their mistake in not providing a complete design. You haven’t signed a contract to go broke pandering to his whimsical approach.

Tell him to go %*&^ himself.

Rohit,



So if it a variation then it is not a general requirement of the activity. You can reschedule the said activity and can claim extension if it affects the critical path. Anyway doing gravel, concrete and geotextile is easier than the labor intensive rip-rapping

Rohit,



If it is an ommission or an addition then it is a variation.



Regards

Rohit,



Read the General Specification of the contract and condition of contract which is the basis of the derivation of the BOQ. If it is clear taht it is the intention of the contract that you put gravel for the function of the said design then you can not ask for time extension and variation of work arising from it hence additional work.
