Working Through a Braced Wall Panel and the Cost to Protect Trees

Earlier in the week my engineer discovered a design blunder I had made on one of my Braced Wall Bands.  I had not ensured that I had a Panel starting within 2.4m of the band edge.

You can read about my fix on the Project Journal

In the meantime, I received two quotes to provide stabilization to my excavation bank around two sets of trees using driven anchors and shotcrete.  One was $30K and the other up to $45K!  I just about had a cow!!!  This is well outside my budget and is not going to work for me.

So I will need to come up with other solutions and will possible need to take down one tree (unpopular choice with me, my wife, and the neighbours).  I will work with the arborist during the air spading to see if we can get any closer to the trees without disturbing structural roots.

For the south elevation, the worst case scenario is that I will need to stabilize the bank using large concrete blocks (2.5' x 2.5' x 5').  I am told this would cost a few thousand. For the NW corner tree, my only option will be to use the blocks.  But this will only be possible if there is no structural roots where the blocks would need to go.  We would need to excavate within 1.5' of one side of the tree if we are going to be able to place these blocks there.  Otherwise, I will need to take down this lovely tree :-(    I will only find out once excavation starts.

In the meantime, I work to empty out the house and start the deconstruction.

Thanks for visiting.
