Appendix 16
Concrete I-Wall and Sheet Piling Material
Recovery, Sampling and Testing: IHNC
Introduction
On Friday, 6 January 2006, samples of the concrete I-wall, reinforcing steel and sheet piling
were taken from the I-wall on west bank of the Inner Harbor Navigation Canal. The location
from which the materials were sampled was the west side of France Rd. near France Road
Parkway. The primary objective of this exercise was to determine material properties of the
I-wall concrete and reinforcing steel, and the sheet piling.
Material Sampling
An approximately eight foot long by 44 inch high section was sawcut from the top of the
concrete I-wall as shown if Figure 16-1. The sample was taken from a location at approximately
Station 0+44 and was labeled IPET-WE-EW 0+44.

This sample was transported to the warehouse at the New Orleans District office. On
11 January, three six inch diameter concrete cores were taken from the wall sample by Beta
Testing & Inspection for compressive testing.
An 8 by 24 inch sample was taken from the web each of two sheet piling at the site. (See
Figures 16-2 and 16-3.) The pilings were labeled IHNC-SP-WS-B1 and IHNC-SP-WS-B2 and
the corresponding samples were labeled IHNC-WS-B1A and IHNC-WS-B2A. The samples were
provided to Beta Testing & Inspection for testing. The sheet piling was transported to the
warehouse at the New Orleans District office.

Four samples of reinforcing steel recovered from the I-wall at approximately Station 2+00
were also provided to Beta Testing and Inspection for testing. The samples were two pieces each
of #4 and #6 rebar and were labeled IHNC WEST 4A, IHNC WEST 4B, IHNC WEST 6A and
IHNC WEST 6B.
Test Results
Complete test results are detailed in the report by Beta Testing and Inspection included in
Attachment A. The test data are summarized in Tables 16-1, 16-2, and 16-3. Material
specifications for IHNC West I-wall system were not found despite extensive effort to locate
them.

The samples of the #6 rebars evidently contained small welds that were not observed during
sampling. Consequently, the samples provided spurious test results and are not included here but
are included in the report by Beta Testing & Inspection in Attachment A.
