NEC Option B Contract

Hi Rayan

I have just googled this on Option B

Option B: Remeasurement priced contract with bill of quantities

The Employer provides a bill of quantities which is priced by the Contractor. The contract price is the

sum of prices for all items in the bill which may include lump sums for certain items. When the work is

done, if it is found by remeasurement that the estimated quantity is not correct, it is corrected and

payment is made to the Contractor to reflect the actual work carried out. Under this option, unlike

Option A, the Employer takes the risk of the correctness of the quantities.

Option B would normally be used where the risk of change in quantities is relatively high. It is not

appropriate for design and build contracts since the Contractor is responsible who designs and

prepares the detailed design and plans.

So unless there is something else in the contract that says the contractor takes all risks in underground obstructions you shouls apply for a compensation event to the Project manager.

Mike,

Thank you for the comments, they are very useful to know, on this basis I am thinking of asking the client to consider using NEC3 Option C, do you think this will be a better option as its based on a activity schedule?

Also if the client was to stick to his guns and say its option B we are using and thats that! are there any time limits or clauses I could use to compensate me?

Hi Rayan

You are stuck with option B so don't try to change it.

The normal time period for notification of a compensation event is 8 weeks so don't hang about.

Best regards

Mike Testro
