In a full or partial price competitive process, the OE will be used mainly to provide advice to the Owner on the relative strengths and weaknesses of each competing TOC. The OE role can be:
• assisting the Owner to identify the true comparative price of each TOC to ensure like with like estimates are being considered;
• reviewing the completed TOC to assess compatibility with the design solution and TOC components;
• checking the scope of work and quantities; and
• checking that the programme and resource plans match the scope and the TOC estimate.
