RE: Unit cost for MSE walls
RE: Unit cost for MSE walls
I just received unit costs from a Contractor in Seattle for MSE walls @ $18 / sf. This, however, would be for height ranges from 4 - 20 feet, but would include reinforcment. sorry, I don't have costs for 40 foot high.
However, we too just prepared very preliminary plans that include MESA walls to 30 feet. If you do find some better estimates for the higher walls, I would appreciate it if you could let me know.
Thanks,

RE: Unit cost for MSE walls
With high walls and polyester reinforcements (we have done walls up to 42 ft height with Keystone Standard units and Mirafi geogrids) the cost of materials goes up to $16/sf.
When you design a MSE wall, there are many variables involved in the analisys, that makes it very difficult to establish a typical cost per sqft. Issues like global stability, access to the site, existing ground materials,etc. can impact your design so heavily that you can have a wall 18 ft as well as anotherwith 10 ft height with the same cost.
Cordially,
