Difficult to answer a question about something that the contract does not legislate for. Search "provisional sums" within Reachback to get other answers around this topic.
The general principle is that we should not need them, and if the Client did need them for budget purposes to get an allowance into the tender then they should be removed upon contract award as the Employer "risk pot" and any such works then instructed as a CE and they have a pot of money to pay for it (which may or may not be enough). Biggest issue always with "provisional sums" is that you cant really allow anything in programme for something you don't know what you are going to be doing.
The answer to your question is "you would hope so", but as Andrew says you have to hope your Works Information mapped out how this would work - and if not I think you should get round the table and talk to each other to get to (hopefully) a suitable agreement.
