Construction Law/Loss/Expense: Invoices + 15%


Dear Peter,

We are the Main Con.

The Contract cites “ …… loss/expense ……… provide invoices …… +15% for admin, overheads and profit…...”

We, for Corporate Policy reasons, will not provide Invoices to substantiate our Claim(s).

Our Claim is submitted on basis of Quotation (cheapest of 3) + 35% (note: not 15%).

The 35% represents our actual overheads at 28% (for this Project) and profit at 7% (Corporate level). Let’s assume that said uplifts are verifiable.

The Employer’s position is “we pay Quotation with no uplift or Invoice +15%. Your decision”

Who is correct?

Dear martincymru,

As the Employer states 'your decision'.  

The Contracts states the basis for reimbursement, but you want to change it unilaterally.  On what contractual basis?  I suggest that you would find it very difficult to justify 35% overheads, especially if you had to do it on the basis of audited accounts.

Value . . .
It's unwise to pay too much, but it's unwise to pay too little. When you pay too much you lose a little money, that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing you bought it to do.
The common law of business balance prohibits paying a little and getting a lot. It can't be done. If you deal with the lowest bidder, it's well to add something for the risk you run.
And if you do that, you will have enough to pay for something better.
