SCOPE OF SERVICES
The services conducted by Universal during our geotechnical exploration are as follows: •
Drill ten (10) Standard Penetration Test (SPT) borings adjacent to the existing culvert structures (at locations chosen by the client) to depths of 6½ to 35 feet below existing ground surface or water elevation.
•
Secure samples of representative soils encountered in the soil borings for review, laboratory analysis and classification by a Geotechnical Engineer.
•
Conduct laboratory testing on selected soil samples obtained in the field to determine their engineering properties.
•
Assess the existing soil conditions with respect to the proposed construction.
•
Prepare a report which documents the results of our exploration and analysis with geotechnical engineering recommendations.

FIELD EXPLORATION
The SPT soil borings was performed with a truck mounted drilling rig and a barge mounted portable rig. Universal located the boring locations by measuring from existing on-site landmarks shown on aerial photographs. The approximate boring locations are shown on the Report of SPT Boring sheets in Appendix B. The SPT borings, designated B-1 through B-7, B-1A, B-4A and B-7A, were performed in general accordance with the procedures of ASTM D 1586 “Standard Method for Penetration Test and Split-Barrel Sampling of Soils”. SPT sampling was performed continuously in the top ten feet to detect variations in the near surface soil profile and on approximate five feet centers thereafter. The boreholes were grouted upon completion.
6.0
LABORATORY TESTING
The soil samples recovered from the soil borings were returned to our laboratory and visually classified in general accordance with ASTM D 2487 “Standard Classification of Soils for Engineering Purposes” (Unified Soil Classification System). We selected representative soil samples from the SPT borings for laboratory testing to aid in classifying the soils and to help to evaluate the general engineering characteristics of the site soils. The results of these tests are shown on the boring log sheets (and gradation curves) in Appendix B. A summary of the tests performed is shown in Table II.

SUBSURFACE CONDITIONS
The results of our field exploration and laboratory analysis, together with pertinent information obtained from the SPT borings, such as soil profiles and penetration resistance are shown on the boring log sheets included in Appendix B. The soil profiles were prepared from field logs after the recovered soil samples were examined by a Geotechnical Engineer. The stratification lines shown on the boring log represent the approximate boundaries between soil types, and may not depict exact subsurface soil conditions. For detailed soil profiles, refer to the attached boring log sheets. In general, the soils encountered at the land boring locations (B-1A, B-4A, B-5 and B-7A) consisted mostly of 2½ to 4 feet of silty sands with limerock [SM] underlain by 7 to 8 feet of highly organic fibrous peat [PT]. These strata are underlain by limestone and silty sands [SM,

SP-SM], to the maximum termination depth of 35 feet below ground surface. Layers of sandy clay [CL] were encountered at boring locations B-1A and B-7A. At the barge boring locations (B-1 through B-4, B-6 and B-7), the soils generally consisted of 1 to 2½ feet of organic silts [OL] (bottom sediments) underlain by limestone and silty sands [SM] to the maximum termination depth of 16 feet below the water elevation. Water depths ranged from roughly 5 to 10 feet at the barge boring locations.
8.0
GROUNDWATER CONDITIONS
We measured the groundwater level (or water depth) at the boring locations on February 16 through 18, 2010 during drilling operations. The groundwater level depths at the land borings ranged from roughly 3 to 4 feet at the time of drilling. The water depths at the barge borings ranged from 5 to 10 feet. The groundwater level (or water depth) at the time of drilling at each boring location is shown on the attached boring log sheets. Fluctuations in groundwater levels should be anticipated throughout the year, primarily due to seasonal variations in rainfall, surface runoff, and other factors that may vary from the time the borings were conducted.

GENERAL RECOMMENDATIONS
This report contains the results of our exploration, an engineering interpretation of these with respect to the project characteristics described to us, and recommendations for soil parameters for sheet pile design, which will be performed by others. Universal Engineering Sciences can not be held responsible for any analysis or engineering interpretation of the data, or conclusions, opinions, or recommendations made by others based upon the data presented in this report. Please note that very dense/hard limestone was encountered at the boring locations. Sheet pile installations through the rock zones may not be possible with typical techniques. Pre-drilling (or other alternate installation methods) may be necessary to achieve the required penetration depths. The tables in Appendix C present soil parameters for use in design of the piling at each of the boat lock structures. Included in the tables are the average SPT “N” values, soil description, soil unit weights, friction angle, cohesion and earth pressure coefficients, as a function of elevation. The soil parameters provided represent ultimate values and therefore, the designer should apply appropriate factors of safety.
10.0
LIMITATIONS
This report has been prepared in order to aid the client/engineer in the design of the proposed sheet piling for the project. The scope is limited to the specific project and locations described herein. Our description of the project's design parameters represents our understanding of the significant aspects relevant to soil characteristics. In the event that any changes in the design or location of the structures as outlined in this report are planned, we should be informed so the changes can be reviewed and the conclusions of this report modified, if required, and approved in writing by Universal.

The recommendations submitted in this report are based upon the data obtained from the soil boring performed at the location indicated on the Boring Location Plan and from other information as referenced. This report does not reflect any variations which may occur within unexplored areas of the site or below the termination depth. The nature and extent of such variations may not become evident until the course of construction. If variations become evident, it will then be necessary for a re-evaluation of the recommendations of this report after performing on-site observations during the construction period and noting the characteristics of the variations. All users of this report are cautioned that there was no requirement for Universal to attempt to locate any man-made buried objects or identify any other potentially hazardous conditions that may exist at the site during the course of this exploration. Therefore no attempt was made by Universal to locate or identify such concerns. Universal cannot be responsible for any buried man-made objects or environmental hazards which may be subsequently encountered during construction that are not discussed within the text of this report. We can provide this service if requested. A further description of the scope and limitations of this report please review the document attached within Appendix E "Important Information About Your Geotechnical Engineering Report" prepared by ASFE/Professional Firms Practicing in the Geosciences. We also present documents in Appendix E titled "Constraints and Restrictions", to bring to your attention the potential concerns and the basic limitations of a typical geotechnical report.

CONSTRAINTS AND RESTRICTIONS WARRANTY Universal Engineering Sciences has prepared this report for our client for his exclusive use, in accordance with generally accepted soil and foundation engineering practices, and makes no other warranty either expressed or implied as to the professional advice provided in the report. UNANTICIPATED SOIL CONDITIONS The analysis and recommendations submitted in this report are based upon the data obtained from soil borings performed at the locations indicated on the Boring Location Plan. This report does not reflect any variations which may occur between these borings. The nature and extent of variations between borings may not become known until excavation begins. If variations appear, we may have to re-evaluate our recommendations after performing on-site observations and noting the characteristics of any variations. CHANGED CONDITIONS We recommend that the specifications for the project require that the contractor immediately notify Universal Engineering Sciences, as well as the owner, when subsurface conditions are encountered that are different from those present in this report. No claim by the contractor for any conditions differing from those anticipated in the plans, specifications, and those found in this report, should be allowed unless the contractor notifies the owner and Universal Engineering Sciences of such changed conditions. Further, we recommend that all foundation work and site improvements be observed by a representative of Universal Engineering Sciences to monitor field conditions and changes, to verify design assumptions and to evaluate and recommend any appropriate modifications to this report. MISINTERPRETATION OF SOIL ENGINEERING REPORT Universal Engineering Sciences is responsible for the conclusions and opinions contained within this report based upon the data relating only to the specific project and location discussed herein. If the conclusions or recommendations based upon the data presented are made by others, those conclusions or recommendations are not the responsibility of Universal Engineering Sciences. CHANGED STRUCTURE OR LOCATION This report was prepared in order to aid in the evaluation of this project and to assist the architect or engineer in the design of this project. If any changes in the design or location of the structure as outlined in this report are planned, or if any structures are included or added that are not discussed in the report, the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed and the conclusions modified or approved by Universal Engineering Sciences. USE OF REPORT BY BIDDERS Bidders who are examining the report prior to submission of a bid are cautioned that this report was prepared as an aid to the designers of the project and it may affect actual construction operations.
E-2.1
Bidders are urged to make their own soil borings, test pits, test caissons or other investigations to determine those conditions that may affect construction operations. Universal Engineering Sciences cannot be responsible for any interpretations made from this report or the attached boring logs with regard to their adequacy in reflecting subsurface conditions which will affect construction operations. STRATA CHANGES Strata changes are indicated by a definite line on the boring logs which accompany this report. However, the actual change in the ground may be more gradual. Where changes occur between soil samples, the location of the change must necessarily be estimated using all available information and may not be shown at the exact depth. OBSERVATIONS DURING DRILLING Attempts are made to detect and/or identify occurrences during drilling and sampling, such as: water level, boulders, zones of lost circulation, relative ease or resistance to drilling progress, unusual sample recovery, variation of driving resistance, obstructions, etc.; however, lack of mention does not preclude their presence. WATER LEVELS Water level readings have been made in the drill holes during drilling and they indicate normally occurring conditions. Water levels may not have been stabilized at the last reading. This data has been reviewed and interpretations made in this report. However, it must be noted that fluctuations in the level of the groundwater may occur due to variations in rainfall, temperature, tides, and other factors not evident at the time measurements were made and reported. Since the probability of such variations is anticipated, design drawings and specifications should accommodate such possibilities and construction planning should be based upon such assumptions of variations. LOCATION OF BURIED OBJECTS All users of this report are cautioned that there was no requirement for Universal Engineering Sciences to attempt to locate any man-made buried objects during the course of this exploration and that no attempt was made by Universal Engineering Sciences to locate any such buried objects. Universal Engineering Sciences cannot be responsible for any buried man-made objects which are subsequently encountered during construction that are not discussed within the text of this report. TIME This report reflects the soil conditions at the time of field activities. If the report is not used in a reasonable amount of time, significant changes to the site may occur and addition reviews may be required.

FIELD EXPLORATION
The SPT soil borings was performed with a truck mounted drilling rig and a barge mounted portable rig. Universal located the boring locations by measuring from existing on-site landmarks shown on aerial photographs. The approximate boring locations are shown on the Report of SPT Boring sheets in Appendix B. The SPT borings, designated B-1 through B-7, B-1A, B-4A and B-7A, were performed in general accordance with the procedures of ASTM D 1586 “Standard Method for Penetration Test and Split-Barrel Sampling of Soils”. SPT sampling was performed continuously in the top ten feet to detect variations in the near surface soil profile and on approximate five feet centers thereafter. The boreholes were grouted upon completion.
6.0
LABORATORY TESTING
The soil samples recovered from the soil borings were returned to our laboratory and visually classified in general accordance with ASTM D 2487 “Standard Classification of Soils for Engineering Purposes” (Unified Soil Classification System). We selected representative soil samples from the SPT borings for laboratory testing to aid in classifying the soils and to help to evaluate the general engineering characteristics of the site soils. The results of these tests are shown on the boring log sheets (and gradation curves) in Appendix B. A summary of the tests performed is shown in Table II.

SUBSURFACE CONDITIONS
The results of our field exploration and laboratory analysis, together with pertinent information obtained from the SPT borings, such as soil profiles and penetration resistance are shown on the boring log sheets included in Appendix B. The soil profiles were prepared from field logs after the recovered soil samples were examined by a Geotechnical Engineer. The stratification lines shown on the boring log represent the approximate boundaries between soil types, and may not depict exact subsurface soil conditions. For detailed soil profiles, refer to the attached boring log sheets. In general, the soils encountered at the land boring locations (B-1A, B-4A, B-5 and B-7A) consisted mostly of 2½ to 4 feet of silty sands with limerock [SM] underlain by 7 to 8 feet of highly organic fibrous peat [PT]. These strata are underlain by limestone and silty sands [SM,

SP-SM], to the maximum termination depth of 35 feet below ground surface. Layers of sandy clay [CL] were encountered at boring locations B-1A and B-7A. At the barge boring locations (B-1 through B-4, B-6 and B-7), the soils generally consisted of 1 to 2½ feet of organic silts [OL] (bottom sediments) underlain by limestone and silty sands [SM] to the maximum termination depth of 16 feet below the water elevation. Water depths ranged from roughly 5 to 10 feet at the barge boring locations.
8.0
GROUNDWATER CONDITIONS
We measured the groundwater level (or water depth) at the boring locations on February 16 through 18, 2010 during drilling operations. The groundwater level depths at the land borings ranged from roughly 3 to 4 feet at the time of drilling. The water depths at the barge borings ranged from 5 to 10 feet. The groundwater level (or water depth) at the time of drilling at each boring location is shown on the attached boring log sheets. Fluctuations in groundwater levels should be anticipated throughout the year, primarily due to seasonal variations in rainfall, surface runoff, and other factors that may vary from the time the borings were conducted.

GENERAL RECOMMENDATIONS
This report contains the results of our exploration, an engineering interpretation of these with respect to the project characteristics described to us, and recommendations for soil parameters for sheet pile design, which will be performed by others. Universal Engineering Sciences can not be held responsible for any analysis or engineering interpretation of the data, or conclusions, opinions, or recommendations made by others based upon the data presented in this report. Please note that very dense/hard limestone was encountered at the boring locations. Sheet pile installations through the rock zones may not be possible with typical techniques. Pre-drilling (or other alternate installation methods) may be necessary to achieve the required penetration depths. The tables in Appendix C present soil parameters for use in design of the piling at each of the boat lock structures. Included in the tables are the average SPT “N” values, soil description, soil unit weights, friction angle, cohesion and earth pressure coefficients, as a function of elevation. The soil parameters provided represent ultimate values and therefore, the designer should apply appropriate factors of safety.
10.0
LIMITATIONS
This report has been prepared in order to aid the client/engineer in the design of the proposed sheet piling for the project. The scope is limited to the specific project and locations described herein. Our description of the project's design parameters represents our understanding of the significant aspects relevant to soil characteristics. In the event that any changes in the design or location of the structures as outlined in this report are planned, we should be informed so the changes can be reviewed and the conclusions of this report modified, if required, and approved in writing by Universal.

The recommendations submitted in this report are based upon the data obtained from the soil boring performed at the location indicated on the Boring Location Plan and from other information as referenced. This report does not reflect any variations which may occur within unexplored areas of the site or below the termination depth. The nature and extent of such variations may not become evident until the course of construction. If variations become evident, it will then be necessary for a re-evaluation of the recommendations of this report after performing on-site observations during the construction period and noting the characteristics of the variations. All users of this report are cautioned that there was no requirement for Universal to attempt to locate any man-made buried objects or identify any other potentially hazardous conditions that may exist at the site during the course of this exploration. Therefore no attempt was made by Universal to locate or identify such concerns. Universal cannot be responsible for any buried man-made objects or environmental hazards which may be subsequently encountered during construction that are not discussed within the text of this report. We can provide this service if requested. A further description of the scope and limitations of this report please review the document attached within Appendix E "Important Information About Your Geotechnical Engineering Report" prepared by ASFE/Professional Firms Practicing in the Geosciences. We also present documents in Appendix E titled "Constraints and Restrictions", to bring to your attention the potential concerns and the basic limitations of a typical geotechnical report.

APPENDIX E
CONSTRAINTS AND RESTRICTIONS WARRANTY Universal Engineering Sciences has prepared this report for our client for his exclusive use, in accordance with generally accepted soil and foundation engineering practices, and makes no other warranty either expressed or implied as to the professional advice provided in the report. UNANTICIPATED SOIL CONDITIONS The analysis and recommendations submitted in this report are based upon the data obtained from soil borings performed at the locations indicated on the Boring Location Plan. This report does not reflect any variations which may occur between these borings. The nature and extent of variations between borings may not become known until excavation begins. If variations appear, we may have to re-evaluate our recommendations after performing on-site observations and noting the characteristics of any variations. CHANGED CONDITIONS We recommend that the specifications for the project require that the contractor immediately notify Universal Engineering Sciences, as well as the owner, when subsurface conditions are encountered that are different from those present in this report. No claim by the contractor for any conditions differing from those anticipated in the plans, specifications, and those found in this report, should be allowed unless the contractor notifies the owner and Universal Engineering Sciences of such changed conditions. Further, we recommend that all foundation work and site improvements be observed by a representative of Universal Engineering Sciences to monitor field conditions and changes, to verify design assumptions and to evaluate and recommend any appropriate modifications to this report. MISINTERPRETATION OF SOIL ENGINEERING REPORT Universal Engineering Sciences is responsible for the conclusions and opinions contained within this report based upon the data relating only to the specific project and location discussed herein. If the conclusions or recommendations based upon the data presented are made by others, those conclusions or recommendations are not the responsibility of Universal Engineering Sciences. CHANGED STRUCTURE OR LOCATION This report was prepared in order to aid in the evaluation of this project and to assist the architect or engineer in the design of this project. If any changes in the design or location of the structure as outlined in this report are planned, or if any structures are included or added that are not discussed in the report, the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed and the conclusions modified or approved by Universal Engineering Sciences. USE OF REPORT BY BIDDERS Bidders who are examining the report prior to submission of a bid are cautioned that this report was prepared as an aid to the designers of the project and it may affect actual construction operations.
E-2.1
Bidders are urged to make their own soil borings, test pits, test caissons or other investigations to determine those conditions that may affect construction operations. Universal Engineering Sciences cannot be responsible for any interpretations made from this report or the attached boring logs with regard to their adequacy in reflecting subsurface conditions which will affect construction operations. STRATA CHANGES Strata changes are indicated by a definite line on the boring logs which accompany this report. However, the actual change in the ground may be more gradual. Where changes occur between soil samples, the location of the change must necessarily be estimated using all available information and may not be shown at the exact depth. OBSERVATIONS DURING DRILLING Attempts are made to detect and/or identify occurrences during drilling and sampling, such as: water level, boulders, zones of lost circulation, relative ease or resistance to drilling progress, unusual sample recovery, variation of driving resistance, obstructions, etc.; however, lack of mention does not preclude their presence. WATER LEVELS Water level readings have been made in the drill holes during drilling and they indicate normally occurring conditions. Water levels may not have been stabilized at the last reading. This data has been reviewed and interpretations made in this report. However, it must be noted that fluctuations in the level of the groundwater may occur due to variations in rainfall, temperature, tides, and other factors not evident at the time measurements were made and reported. Since the probability of such variations is anticipated, design drawings and specifications should accommodate such possibilities and construction planning should be based upon such assumptions of variations. LOCATION OF BURIED OBJECTS All users of this report are cautioned that there was no requirement for Universal Engineering Sciences to attempt to locate any man-made buried objects during the course of this exploration and that no attempt was made by Universal Engineering Sciences to locate any such buried objects. Universal Engineering Sciences cannot be responsible for any buried man-made objects which are subsequently encountered during construction that are not discussed within the text of this report. TIME This report reflects the soil conditions at the time of field activities. If the report is not used in a reasonable amount of time, significant changes to the site may occur and addition reviews may be required.
