The Transmission Gully builder, CPB HEB Joint Venture is continuing to work hard to complete construction, but there is still plenty of work needing to be finished before the road can open.

Under the PPP contract, it is the responsibility of the contractor, Wellington Gateway Partnership (WGP) and their sub-contractor, CPB HEB, to deliver a road that meets the safety, quality and environmental standards agreed in the project agreement, and expected by the public.

These tests are important, not just to meet the contractual requirements, but so that there are no major issues that need to be repaired or redone after it’s opened, which could lead to frustrating closures for motorists.

There are 100 safety and quality assurance tests that the contract stipulates must be met before the road can open. There are also 45 consent tasks that WGP and the builder need to complete in order to meet the contractual requirements for road opening.

As at 10 November 2021:

  • 38 final test submissions have been received from the builder, of which 26 have been accepted by the Independent Reviewer as meeting the required specifications
  • 42 partial submissions have been made and 20 tests are yet to be submitted
  • Seven of the consent tasks have been completed
  • Of the 38 remaining consent tasks, 36 are underway and have been progressed to varying degrees, and two are not yet started.

Next week, the team doing the road safety audit will be driving through for another pre-opening inspection. This will advise WGP and the builder of any safety issues that need to be addressed before the final road safety inspection just before the road opens.

CPB HEB has rescheduled the postponed northbound paving work at Linden to next weekend.

A date for the postponed paving for the southbound connection is still to be confirmed.

A reminder – while the road may start to look finished, the safety, compliance and assurance tests still need to be completed for the road to open safely to traffic.

Once those standards are met, the PPP contract will move into the service phase – the 25-year maintenance and operations period, after which it will be handed over to Waka Kotahi at an agreed standard.
