Patea Moles Repairs

Since the early 2000’s various reports and maintenance designs have been undertaken. The most recent condition assessment report was completed in 2017 by BTW Company. With that report, it was identified that remedial works are required to be undertaken in a periodic fashion, mainly focused on replacement of block loss in the Moles. Such work was undertaken in 2009 – 2011, and since then further blocks have been lost. Since the closure of the Patea Freezing works, and increased reliance of the road transport network, the function of the Patea Moles has been reduced to training the river entrance and also providing a navigable harbour for largely recreational vessels. To preserve the navigable channel for recreational users, it has been proposed that a periodic maintenance works every few years is required to prolong the structure as best possible and slow the deterioration of the asset.

This contract is for the maintenance repairs of moles situated on the western side (true right bank) of Patea River. The proposed works include placing concrete as void fill to ‘lock-up’ the existing blocks and protect against further degradation as best possible.
The infill will be completed with concrete, placed within shutters, and doweled into the existing structure where there is not geometry to naturally lock the void fill in place.
