Contractors building the Sellwood Bridge have to dig-out significant parts of a newly-poured concrete wall, following technicalproblems.

When large structures like the retaining wall along SW Macadam are poured, big vibrators help the wet concrete settle getting rid of anybubbles.

But contractors Slayden and Sundt had some issues with their vibrators and now there are some unconsolidated areas of concrete along one patch of thewall.

Mike Pullen with Multnomah County says the contractors will have to remove the problem areas and replace it on their own dime, This will not affect the strength of the wall. Itll possibly be even stronger with the new concrete Im told and they do have tools like ultra-sound that are used to make sure there arent any hidden voids in the concrete, hesaid.

Pullen says the project is still on-time and on budget, with the bridge scheduled to open in late2015.
