Forms of contract

  • 17 major contracts used to deliver the project.
  • 11, of which were forms of NEC3, ranging from professional services for

engineering design, through to supply variants for large procurement items and:

  • ECC Option A (priced contract with activity schedule) for transmission

line construction and electrical balance of works.

  • ECC Option C (target contract with activity schedule) for extensive civil

works, including, internal and external roads, turbines foundations and hard stands.

  • We have yet to use the NEC3 form of contract for the turbine supply and

installation work stream in NZ, but did use it for turbine supply for our Mt Mercer site in Victoria, Australia.

Pros

  • The emphasis on early warning and implication for the contractor if they don’t

is probably the single biggest advantage over other forms of contract.

  • Also if you do have a dispute, the mechanics and logic for resolving it are

already well defined and help parties reach agreement earlier than using other forms of contract. Look out for:

  • Contractors that are insufficiently staffed to perform the regular reporting

requirements and forward estimates. Especially when there are numerous sub contractors reporting to the main contractor.
