NEC4 Option B - Blank Quantities in the BOQ

NEC3 and NEC4 Contracts
1

Hi,

I’m currently putting together a BOQ for an NEC4 ECC Option B Project, there are items within where the Contractor would need to fill out the quantities as part of their ITT Submission.

If these quantities, who owns the risk if it is incorrect?

Under the standard form the Client would own the risk or benefit

So if we include a Bill item that lists tonnage of scaffolding but the tonnage is to be filled out by the Contractor as the Scaffold is Contractor design, if they themselves get the quantity wrong, the client is liable?

Under clause 60.6, if there is a mistake in the Bill of Quantities, the Project Manager gives an instruction to correct it; that would be a compensation event.
The quantity in the BoQ being wrong is also a compensation event under clause 60.4 if it’s sufficiently large (value = more than 0.5% of the total of the prices at the Contract Date).
