Construction Law/Lump Sum Contract


Dear Sir

For the lump sum contract assume that the 200 nr of light fittings are shown in the drawings. However the BOQ only have 150 nr and rate is QAR 25 (amount is 150 x 25 = 3750).

Later the engineer instructed to omit the particular type of light fittings in some area (qty 50 nr). There is a provision in BOQ to include missing items, and however the Contractor not corrected the qty.

Then correct rate for the omission is either 25 or 18.75 (3750/200).

Could you explain with reasons.



Dear Sudantha,

You have not mentioned the conditions of Contract in your question.The Contractor could correct the the quantity in BoQ as per provisions of the Contract but he did not do so.Generally drawings have the priority over BoQ. Thus more logical rate for omission should be 18.75.

But we need to see the priority. If drawing has the priority, above said rate will be followed. On the other hand, if BOQ have the priority in {Priority of Documents], then 25 QAR would be valid.
