Cost estimation

The Cost estimation manual (SM014) is for use by consultants when preparing cost estimates. It contains all the NZ Transport Agency Waka Kotahi (NZTA) procedures and guidelines for producing, reviewing or submitting estimates for capital projects. The manual has been updated to align with our Business Case Approach.

It should be noted that all estimates exclude escalation. However, all funding application assessments are out-turn estimates and should include escalation.

Note:

• Property costs to be estimated by the property acquisition agent.
• NZTA is to provide estimate for the NZTA-managed costs.
• Fees to be removed from estimates once they become sunk costs.
• Parallel estimates and cost peer reviews to be carried out as required.
• Estimates are to derive a project out-turn cost, not just contract cost, thus include a raft of ancillary costs.
• SM014 spreadsheets are available electronically in the Resources section.
