Construction Law/FIDIC 2010


Please explain Clause 12.3 (a) iii, "this change in quantity directly changes the Cost per unit quantity of this item by more than 1%"

I do not understand how change in quantity changes  Cost per unit quantity (unit rate).

Dear Madan

Thanks for your Question.

I would be able to advise you better if you could post your query in details.

However as per my understanding; it seems that you are refering to FIDIC MDB Harmonised Edition.

Qty and unit rate does depend on can be compared with this scenario "if we buy 10 items and the unit price per pcs is Rs 100 per item , the total price would be Rs 1000,if we buy the these items in bulk quantity the unit price shall be cheaper than small quantities (less than Rs10 ......."

However if you can proove to the Engineer with adequate substantiations you may succeed in getting better rates should there be a variation or so...
