When comparing timelines for the different selection methods it should not be assumed that non-price competition is a faster process. Adopting open-ended cost reimbursement arrangements without competition exposes an Owner to the risk of prolonged timelines and lower efficiency in TOC development. Furthermore, there is a high risk for the Owner of being 'captured' by Proponents when engaged to undertake early works during the TOC development process and prior to finalising and agreeing the PAA.
Any development process relying on information from sources outside the control of parties to the alliance, (e.g. approvals and land access) runs the same risk of delayed timelines and additional cost to the Owner.
