The Head Contract Guaranteed Maximum Price (GMP) templates broadly align with the standard Head Contract, including the adoption of a fixed-time obligation and flexibility for construct only, design and construct or document and construct delivery.

This contract delivery model:

  • requires the Tenderer to tender (among other things) its proposed GMP and the Works it proposes will be undertaken as:
    • Contractor's Work (being Works performed by the Tenderer or a Related Body Corporate of the Tenderer)
    • Reimbursable Work (being Works performed by subcontractors).
  • provides that the Contract Price will not exceed the GMP subject to adjustments in accordance with the Conditions of Contract
  • provides that if the Contract Price is less than the GMP, the Contractor is entitled to a share in the difference between the Contract Price and the GMP in accordance with the Conditions of Contract.
