Introduction

Task Order DY08, Core Drilling, Soil Sampling, and Laboratory Testing for the Port Arthur

Resident Office Shoreline Stabilization project, Port Arthur, Texas, was awarded to Quaternary

Resource Investigations, LLC (QRI) on November 19, 2013 (Notice to Proceed (NTP) received on

November 29, 2013). The primary purpose of this Task Order was to obtain geotechnical

information for shoreline stabilization at the Port Arthur Resident Office, Jefferson County,

Texas. A total of 5 borings, numbered 13‐1001 through 13‐1005, were drilled to depths of 80

and 100 feet as shown on

Table 1

below.

Borings

Below is a table summarizing the 5 borings drilled under Task Order DY08. The table includes

Boring Number, Investigation Feature, Depth (ft), and a description of unusual subsurface

conditions or difficulties in drilling that were encountered (if any). Boring Summary Sheets and

Field boring logs (

Appendix A

) should be referenced for information concerning each boring.

Test data

As per the Table of Required Services, test assignments were provided by the USACE POC as

listed in Table 2. All tests were performed by QRI’s contract laboratory, Terracon Consultants,

Inc., on portions of the samples that were considered representative of the predominant

material composition of the overall sample. The laboratory recorded on the final summary

sheets the results of unit dry weight tests, moisture content tests, and visual classifications

incidental to performing unconfined compression tests, triaxial tests (including UU and CU

tests), and other tests. Results of moisture content testing and visual classifications incidental

to performing moisture content, unit dry weight, Atterberg limits, and sieve analyses, were also

included on the final test summary sheets provided by the laboratory. A complete set of
