I fully agree with Mounir. The type of contract can generally changeable by mutual agreement.
Many times it is not clear who's responsible for change of the type of contract from the Lump Sum Contract to other types. It might result from the scope change of the Works but it is not common to change types of the contract.
I am not sure of your organization's position from your statement. Are you the staff of the subcontractor or client? If you are a consultant engineer to represent the client, it is not simple because it might be from a major default of the client. Best way to handle this issue is between the Client and main Contractor by trade-off of their interests or objectives on time and cost as a result of change of type of contract. Or the Contractor should be reimbursed any costs and time for changed scope (additional items) under the current L.S. Contract if both parties agree to do so and amend the relevant Clauses of the Contract.
