Heads of terms
"Heads of Terms" refers to a non-binding document outlining the key terms and conditions agreed upon by parties before the finalisation of a formal contract. It serves as a preliminary agreement that sets the framework for further negotiations and drafting of the detailed contract.
It summarises the principal points of the agreement between the parties,and establishes a basis for detailed negotiations and drafting of the formal contract, ensuring that both parties are on the same page regarding the key aspects. This helps to focus discussions on important issues and prevents misunderstandings or disputes later in the process.
It might include terms such as:
- The scope of work.
- Project timelines.
- Payment terms and conditions.
- Roles and responsibilities of the parties involved.
- Confidentiality provisions.
- Any conditions precedent (conditions that must be met before the agreement becomes effective)
- Procurement and contract strategy. This should include carefully thought out risk allocation (procurement routes might involve bills of quantities, schedules of activities, target cost formulae and part design responsibility).
- Choice of contract.
- Conditions of engagement for consultants.
- Design and collateral warranties.
- Incentive mechanisms.
- Abortive terms.
While Heads of Terms indicate a mutual intent to proceed, they are generally not legally binding except for certain clauses, such as confidentiality and exclusivity, which might be explicitly stated as binding.Heads of Terms can be particularly useful in complex construction projects where multiple parties are involved, helping to streamline the process and set clear expectations before committing to a detailed and binding contract.
