Can anyone tell me what structural engineering design fees to expect for reshoring analysis calculations on a typical RC high-rise building? Is the fee based on building square footage, no. of formwork drawings, or some other fee based criteria?

Usually the fill soil is compacted to 85-100 percent of the maximum density as determined by the Standard or Modified Proctor compaction tests. If you know this to be true in your case and the soil is granular, the angle of internal friction of the soil may be estimated indirectly from...

The excavation is 28 ft. deep and the perimeter of the excavation/pour is irregular (some walls are at 45 deg. angles). In some areas we will be pouring up against an existing concrete basement wall and at other locations we will be pouring up against a braced excavation.

A S.F. of 1.5 to 2.0 should be used for any building structure which could be severely damaged by hydrostatic uplift forces. For non-building type structures (i.e., underground tanks, transformer foundation containment pits, etc.) for which uplift effects are not as detrimental a S.F. of 1.2 to...
Single face wall forms are used to form concrete walls when access from only one side is available. As a result, very high overturning and lateral forces (particularly for an 18' high wall) need to be resisted by the formwork and foundation supporting the formwork.
I have used a S.F. of 1.2 for foundations supporting non-building type structures (i.e., foundations for tanks, silos, transformers, etc.) and 1.5 up to 2.0 for foundations supporting buildings.
The following safety factors are recommended by "Duncan" in his foundation design book...
Can anyone provide me with the vendor and/or product name specializing in single face wall forming?
Alternatively, does anyone have an innovative, or tried and true method for building single face formwork for an 18 ft. high wall? I am particularly interested in an ecomoncal means for design...
There is an excellent book which you can purchase from the ICBO's web site (http://www.icbo.org/) titled: "Engineering Sign Structures," by Benjamin Jones. Everything you need to know regarding sign structures and their foundations can be found in this text.

I believe the book Qshake is referring to is "Standard Cantilever Retaining Walls," by Morton Newman. It was published in 1976 and reprinted by Robert E. Krieger Publishing Company (a publishing company for out of print books) in 1981. The entire book (648 pages) consists of worked...
