• Allows Contractor to join the design team near the start
and still be chosen in a competitive manner

(This is from lecture but needs clarification)
• P&G = Preliminaries and General or General– Contractor’s costs to run the job.
Site establishment costs.
• Margins = profit Vary in value– 10%? Boom times = 17% in remote areas
• Auckland commercial 8-10% some 12.5%

  • Ongoing roll-out programmes
  • Same client and project types
24
Q

What is “selective tendering (by invitation)”?

A

• Contractors invited to tender based on recognised
capabilities to suit the project requirements
• Client agrees and confirms tender list

• Specialist projects
• Private sector clients

25
