Notes:1. Data concerning the various strata have been interpreted at boring locations only. The stratigraphy between

borings may vary from that shown.2. Refer to plan view for subsurface profile location. For strata details and symbol legend, see Subsurface

Profile Legend and boring logs appended to this report.3. Numbers displayed beside boring(s) represent SPT "N" values and PID readings corresponding to their

respective sampling interval. Where coring was performed, numbers represent Recovery and RQD values.4. Soil Samples screened in the field using a Thermal Environmental Systems Model 580S Photoionization

Detector. The Meter was calibrated relative to a benzene in air standard. N.D. = None Detected.

Appendix 5 2008 Geotechnical Laboratory

Testing

Appendix 6 Limitations

GEOTECHNICAL LIMITATIONS Explorations 1. The analyses and recommendations submitted in this report are based in part upon the data

obtained from widely spaced subsurface explorations. The nature and extent of variations between these explorations may not become evident until further explorations are made and construction occurs. If variations then appear evident, it will be necessary to reevaluate the recommendations of this report.

2. The generalized soil and bedrock profile described in the text is intended to convey trends in

subsurface conditions. The boundaries between strata are approximate and idealized and have been developed by interpretations of widely spaced explorations and samples; actual soil and bedrock transitions are probably more erratic. For specific information, refer to the boring logs.

3. The geologic and geomorphologic settings at this site are complex and the uncertain historic

site usage has resulted in the varied distribution and stress history of compressible soils across the site. Limited spacing of borings and lab testing can at best, only allow for estimates to be developed for duration and magnitude of consolidation settlements.

4. Water level readings have been made in the drill holes at times and under conditions stated

on the boring logs. These data have been reviewed and interpretations have been made in the text of this report. However, it must be noted that fluctuations in the level of the groundwater may occur due to variations in river levels, rainfall, temperature, and other factors occurring since the time measurements were made.

Review 5. In the event that any changes in the nature, design or location, of the proposed retaining wall

the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed and conclusions of this report modified or verified in writing by GeoDesign, Inc. It is recommended that this firm be provided the opportunity for a general review of design and specifications in order that earthwork and foundation recommendations may be properly interpreted and implemented in the design and specifications.

Use of Report 6. This report has been prepared for the exclusive use H.W. Lochner, Inc., the Connecticut

Department of Transportation (ConnDOT), and other members of the design team for specific application to the construction of Retaining Wall 101 located south of the proposed Broad Street Bridge in Hartford, Connecticut, in accordance with generally accepted soil and foundation engineering practices. No other warranty, express or implied, is made.

7. This final design soil and foundation engineering report has been prepared for this project

by GeoDesign. This report is for design purposes only and is not sufficient to prepare an accurate bid. Contractors wishing a copy of the report may secure it with the understanding that its scope is limited to design considerations only.
