Routine tests on Marlborough’s multimillion-dollar bridge have uncovered road defects that will delay completion.
A problem with the asphalt on the Ōpaoa River Bridge was discovered by road workers carrying out standard quality control tests.
The construction company will have to pay for vital repairs delaying completion on the 10-metre wide bridge until the end of the year.
Originally expected to open in mid-2020, the bridge was set to cost around $21 million but has jumped to almost $22.7 million.
Waka Kotahi senior manager for project delivery Andy Thackwray says rigorous testing is carried out to find any potential problems.
“During construction, as road surfacing work is carried out, the pavement is subjected to robust testing so we can identify and remedy any issues before a project is completed.
“In this case, the top surfacing asphalt layer on the bridge was found to have deficiencies that, if left, would have resulted in replacement being required much sooner than its expected design life.
“The cost of remedial work will be at the contractor’s expense,” he says.
Final work on the bridge is expected to continue until mid-October with road bosses hoping to celebrate completion late this year.
Waka Kotahi has kept project delays to a minimum over the Covid-19 lockdown.
While pavement works will be completed in mid-October, smaller projects, including landscaping, work on the heritage bridge, and reinstatement of the holiday camp below the new bridge will continue into November.
“With the project progressing so well we’re now starting to plan how we can properly celebrate the completion of this important regional project alongside our partners, stakeholders and community,” Andy says.
“This will be a truly spectacular asset for the community.”
Motorists are being warned to expect delays while works continue.
Drivers are asked to please plan and be patient while the essential works are completed.
In the likelihood of bad weather, these works will be postponed for the next fine day.
