However, due to the highly variable soil conditions observed during initial construction of the lake edge walls, we believe it would be prudent to perform additional proof testing of the production nails (2% minimum, or 1 every 50). The shop drawings (attached) have been revised accordingly to call for the additional testing. The proof test logs are also attached for the three different nail lengths on the project. Let me know if you have any questions. Joel R. Clark, P.E. Craig Olden, Inc.
