It has been several years since I have installed a timber wall. The dimensions of the wall is 90' long and 10' high. I will be using 6x6 pressure treated timbers. The timbers are costing me 14.00 a piece. I am wanting to see what your labor rates are. If you have any suggestions, feel free to let me now.

Only you know that. How much excavation? Is there a setback? How much stone and backfil?

jezz...that's one big arse wall for timber.


I remember a quote for one that was about 60 feet in length and 4-5 in height about 3-4 years ago. I remember after all was said and done I was just shy of 50 per face foot after factoring everything in. There is a LOT of labor involved in a timber wall. All the extra excavation for the tiebacks, rebar, all the spikes/screws, etc.

Please take photos as you go and post them up. 10ft is high for timber.

10' is realy high for timber. I would recommend doing 2 seperate walls of 6 and 4. Or maybe using concrete retaining wall blocks with Geo Grid.

Your tie back system is going to look like a wooden roller coaster. Back fililng that will take some skill and time.

Good Luck

You'll have a sizeable percentage of your 6x6's behind the wall as tie-backs...just off the top of my head it's got to be an addtional 20-30% more material.

Labor will be extensive and the process will be very slow.

Almost certainly more expensive than segmented...why not install a permanent, less expensive solution and go with a segmented retaining wall?

Faster - cheaper - longer lasting.

You have an engineer that is going to sign off on this project? Only you know your labor rates. 10' of timber wall is not a good idea. There are other options that are far superior.

I was thinking the same thing. If I were to build a wall that size here, I would need a bldg. permit and engineering, not sure if a wooden wall would be approved.

I also agree w/ the concern as to the height of the wall using 6"x6". Personally, I would upgrade to a 6"x8" and consult w/ an engineer. If you were to stair step 1", that would only give you 4" of surface contact on each course.That's 22 timbers high, not including the courses you would need to bury.
