How is the ECC structured?

2

The ECC has four parts:

  1. Core Clauses - there are 9 sections of core clauses (General, Contractor’s responsibilities, Time, Testing and Defects, Payment, Compensation Events, Title, Risks and Insurance and Termintation). These clauses should be applicable to any project.

  2. Main Option Clauses - there are 6 main option clauses (Option A: Priced contract with activity schedule, B: Priced contract with bill of quantities, C: Target contract with activity schedule, D: Target contract with bill of quantities, E: Cost reimbursable contract, F: Management contract). One of these options is chosen which will determine the pricing mechanism for a particular project.

  3. Secondary Option Clauses - there are 18 secondary option clauses (Options X, Y and Z). The user can choose any of these options to fine tune the contract to meet specific needs. However, he doesn’t have to choose any.

  4. Dispute Resolution Options - There are two options for this: Option W2 for contracts where the Housing Grants, Construction and Regeneration Act 1996 applies; and Option 1 for when the Act is not applicable.
