INTRODUCTION This report presents the results of the subsurface exploration program we recently conducted for the referenced project. This work was performed per our proposal dated January 7, 2011, which you authorized on January 12,2011. Our authorized scope of work included the following:
- Drill one ( 1) standard penetration test boring to a depth of 80 feet.
- Prepare a factual report summarizing our findings.
The scope of our work is intended for geotechnical purposes only. This scope is not intended to explore for the presence of environmental contamination at the site.
PROJECT INFORMATION It is our understanding that the referenced site is a previously graded and currently undeveloped business park. We further understand that the purpose of our subsurface exploration program was to provide a soil profile at one test boring location, selected by you, as shown in Figure 1.

AET Project No. 31-00144- Page 2 of 5 The results of this test boring will be used to determine the feasibility of further development throughout the business park.
Because our scope of services for this project is limited to reporting our findings at only one boring location, information concerning soil bearing capacity values and foundation design for future structures on this site is not provided in this report.
SITE CONDITIONS Surface Observations The following information presents our observations of the existing site conditions at the time of our soil boring activity:
- The site is located to the west of the intersection of Seymour Cray Sr. Boulevard and Lake View Drive in Chippewa Falls, Wisconsin.
- The site is grassy.
- The site is relatively flat.
Soils A log of the test boring is attached. The log contains information concerning soil layering, soil classification, geologic description, and moisture. Relative density or consistency is also noted, which is based on the standard penetration resistance (N-value). The following is a summary of the soil conditions observed at the location of the test boring:
- The soil profile at the location of the test boring consists of fill overlying buried topsoil. The buried topsoil is underlain by coarse alluvial soils.
- The fill consists primarily of silty sand and was encountered to a depth of approximately 3 ~
feet.
AET Project No. 31-00144- Page 3 of 5
- The buried topsoil layer consists primarily of sandy silt and was found to be approximately 1Y2 feet thick.
- The coarse alluvium consists of varying layers of sands with silt, sands, gravelly sands, and sandy gravel. Based on theN-values, these coarse alluvial soils are medium dense to dense.
The boring log indicates the subsurface conditions only at the sampled location. Variations often occur between and beyond borings.
Water Level Measurements The borehole was probed for the presence of ground water, and a water level measurement was taken. The measurement is recorded on the boring log. We measured a ground water level at a depth of about 50 feet. Because the sands and gravels below this depth are waterbearing, we judge this to represent a hydrostatic condition. Because the boring encountered mostly free draining sands and gravel, the water level indicated should be reasonably accurate at this time and location. A discussion of the water level measurement method is presented on the sheet entitled "Exploration/Classification Methods".
Groundwater levels usually fluctuate. Fluctuations occur due to varying seasonal and yearly rainfall and snow melt, as well as other factors.
GEOTECHNICAL CONSIDERATIONS Review of Soil Properties The site soils classified as sand, sand with silt, gravelly sand, and sandy gravel are not judged to be significantly susceptible to frost-related movements. The site soils classified as silty sands are at least moderately susceptible to frost-related movements, but can become highly susceptible if they are wet before they freeze. The site soils classified as sandy silt are highly susceptible to
AET Project No. 31-00144- Page 4 of 5 frost-related movements. The site soils classified as buried topsoil are judged to be compressible.
We cannot make judgments regarding the strength or compressibility of the fill and tops<?il because they were frozen and accurate N-values could not be obtained. We judge the alluvial sands and gravels to have moderate to high strength and low compressibility.
SUBSURFACE EXPLORATION The form "Geotechnical Field Exploration and Testing", which can be found in Appendix A, provides details on sampling, classification, and water level measurement methods. Additional information is provided in the sheets entitled "Boring Log Notes" and "Unified Soil Classification System".
Determining surface elevations at the boring locations was not part of our scope of services and was not performed.
LIMITATIONS Within the limitations of scope, budget, and schedule, our services have been conducted according to generally accepted geotechnical engineering practices at this time and location.
Other than this, no warranty, either express or implied, is intended.
Important information regarding risk management and proper use of this report is given in Appendix B entitled "Geotechnical Report Limitations and Guidelines for Use".

Appendix A Geotechnical Field Exploration and Testing AET Project No. 31-00144 A.l FIELD EXPLORATION The subsurface conditions at the site were explored by drilling and sampling one standard penetration test boring. The location of the boring appears on Figure 1, preceding the Subsurface Boring Log in this appendix.
A.2 SAMPLING METHODS A.2.1 Split-Spoon Samples (SS)- Calibrated to N60 Values Standard penetration (split-spoon) samples were collected in general accordance with ASTM:D1586 with one primary modification. The ASTM test method consists of driving a 2-inch O.D. split-barrel sampler into the in-situ soil with a 140-pound hammer dropped from a height of 30 inches. The sampler is driven a total of 18 inches into the soil. After an initial set of 6 inches, the number of hammer blows to drive the sampler the final 12 inches is known as the standard penetration resistance or N-value.
Our method uses a modified hammer weight, which is determined by measuring the system energy using a Pile Driving Analyzer (PDA) and an instrumented rod.
In the past, standard penetration N-value tests were performed using a rope and cathead for the lift and drop system. The energy transferred to the split-spoon sampler was typically limited to about 60% of its potential energy due to the friction inherent in this system. This converted energy then provides what is known as an N60 blow count.
Most newer drill rigs incorporate an automatic hammer lift and drop system, which has higher energy efficiency and subsequently results in lower N-values than the traditional N60 values. By using the PDA energy measurement equipment, we are able to determine actual energy generated by the drop hammer. With the various hammer systems available, we have found highly variable energies ranging from 55% to over 100%. Therefore, the intent of AET's hammer calibrations is to vary the hammer weight such that hammer energies lie within about 60% to 65% of the theoretical energy of a 140-pound weight falling 30 inches.
The current ASTM procedure acknowledges the wide variation in N-values, stating that N-values of 100% or more have been observed. Although we have not yet determined the statistical measurement uncertainty of our calibrated method to date, we can state that the accuracy deviation of theN-values using this method is significantly better than the standard ASTM Method.
A.2.2 Disturbed Samples (DS)/Spin-up Samples (SU)
Sample types described as DS or SU on the boring logs are disturbed samples, which are taken from the flights of the auger.
Because the auger disturbs the samples, possible soil layering and contact depths should be considered approximate.
A.2.3 Sampling Limitations Unless actually observed in a sample, contacts between soil layers are estimated based on the spacing of samples and the action of drilling tools. Cobbles, boulders, and other large objects generally cannot be recovered from test borings, and they may be present in the ground even if they are not noted on the boring logs.
Determining the thickness of "topsoil" layers is usually limited, due to variations in topsoil definition, sample recovery, and other factors. Visual-manual description often relies on color for determination, and transitioning changes can account for significant variation in thickness judgment. Accordingly, the topsoil thickness presented on the logs should not be the sole basis for calculating topsoil stripping depths and volumes. If more accurate information is needed relating to thickness and topsoil quality definition, alternate methods of sample retrieval and testing should be employed.
A.3 CLASSIFICATION METHODS Soil descriptions shown on the boring logs are based on the Unified Soil Classification System (USCS). The USCS is described in ASTM:D2487 and D2488. Where laboratory classification tests (sieve analysis or Atterberg Limits) have been performed, accurate classifications per ASTM:D2487 are possible. Otherwise, soil descriptions shown on the boring logs are visual-manual judgments.
Charts are attached which provide information on the USCS, the descriptive terminology, and the symbols used on the boring logs.
The boring logs include descriptions of apparent geology. The geologic depositional origin of each soil layer is interpreted primarily by observation of the soil samples, which can be limited. Observations of the surrounding topography, vegetation, and development can sometimes aid this judgment.
A.4 WATER LEVEL MEASUREMENTS Appendix A - Page 1 of 2 AMERICAN ENGINEERING TESTING, INC.
Appendix A Geotechnical Field Exploration and Testing AET Project No. 31-00144 The ground water level measurements are shown at the bottom of the boring logs. The following information appears under Water Level Measurements on the logs:
- Date and Time of measurement
- Sampled Depth: lowest depth of soil sampling at the time of measurement
- Casing Depth: depth to bottom of casing or hollow-stem auger at time of measurement
- Cave-in Depth: depth at which measuring tape stops in the borehole
- Water Level: depth in the borehole where free water is encountered
- Drilling Fluid Level: same as Water Level, except that the liquid in the borehole is drilling fluid The true location of the water table at the boring locations may be different than the water levels measured in the boreholes. This is possible because there are several factors that can affect the water level measurements in the borehole. Some of these factors include: permeability of each soil layer in profile, presence of perched water, amount of time between water level readings, presence of drilling fluid, weather conditions, and use of borehole casing.
A.S LABORATORY TEST METHODS A.S.l Water Content Tests Conducted per AET Procedure 01-LAB-010, which is performed in general accordance with ASTM:D2216 and AASHTO:T265.
A.5.2 Sieve Analysis of Soils (thru #200 Sieve)
Conducted per AET Procedure 01-LAB-040, which is performed in general conformance with ASTM:D6913, Method A.
A.6 TEST STANDARD LIMITATIONS Field and laboratory testing is done in general conformance with the described procedures. Compliance with any other standards referenced within the specified standard is neither inferred nor implied.
A. 7 SAMPLE STORAGE Unless notified to do otherwise, we routinely retain representative samples of the soils recovered from the borings for a period of 30 days.

Appendix B AET Project No. 31-00144 Geotechnical Report Limitations and Guidelines for Use
Appendix B Geotechnical Report Limitations and Guidelines for Use AET Project No. 31-00144 B.l REFERENCE This appendix provides information to help you manage your risks relating to subsurface problems which are caused by construction delays, cost overruns, claims, and disputes. This information was developed and provided by ASFE 1, of which, we are a member firm.
B.2 RISK MANAGEMENT INFORMATION B.2.1 Geotechnical Services are Performed for Specific Purposes, Persons, and Projects Geotechnical engineers structure their services to meet the specific needs of their clients. A geotechnical engineering study conducted for a civil engineer may not fulfill the needs of a construction contractor or even another civil engineer. Because each geotechnical engineering study is unique, each geotechnical engineering report is unique, prepared solely for the client.
No one except you should rely on your geotechnical engineering report without first conferring with the geotechnical engineer who prepared it. And no one, not even you, should apply the report for any purpose or project except the one originally contemplated.
B.2.2 Read the Full Report Serious problems have occurred because those relying on a geotechnical engineering report did not read it all. Do not rely on an executive summary. Do not read selected elements only.
B.2.3 A Geotechnical Engineering Report is Based on A Unique Set of Project-Specific Factors Geotechnical engineers consider a number of unique, project-specific factors when establishing the scope of a study.
Typically factors include: the client's goals, objectives, and risk management preferences; the general nature of the structure involved, its size, and configuration; the location of the structure on the site; and other planned or existing site improvements, such as access roads, parking lots, and underground utilities. Unless the geotechnical engineer who conducted the study specifically indicates otherwise, do not rely on a geotechnical engineering report that was:
- not prepared for you,
- not prepared for your project,
- not prepared for the specific site explored, or
- completed before important project changes were made.
Typical changes that can erode the reliability of an existing geotechnical engineering report include those that affect:
- the function of the proposed structure, as when it's changed from a parking garage to an office building, or from a light industrial plant to a refrigerated warehouse,
- elevation, configuration, location, orientation, or weight of the proposed structure,
- composition of the design team, or
- project ownership.
As a general rule, always inform your geotechnical engineer of project changes, even minor ones, and request an assessment of their impact. Geotechnical engineers cannot accept responsibility or liability for problems that occur because their reports do not consider developments of which they were not informed.
B.2.4 Subsurface Conditions Can Change A geotechnical engineering report is based on conditions that existed at the time the study was performed. Do not rely on a geotechnical engineering report whose adequacy may have been affected by: the passage of time; by man-made events, such as construction on or adjacent to the site; or by natural events, such as floods, earthquakes, or groundwater fluctuations.
Always contact the geotechnical engineer before applying the report to determine if it is still reliable. A minor amount of additional testing or analysis could prevent major problems.
ASFE, 8811 Colesville Road/Suite Gl06, Silver Spring, MD 20910 Telephone: 301/565-2733 : www.asfc.org Appendix B -Page 1 of 2 AMERICAN ENGINEERING TESTING, INC
Appendix B Geotechnical Report Limitations and Guidelines for Use AET Project No. 31-00144 B.2.5 Most Geotechnical Findings Are Professional Opinions Site exploration identified subsurface conditions only at those points where subsurface tests are conducted or samples are taken. Geotechnical engineers review field and laboratory data and then apply their professional judgment to render an opinion about subsurface conditions throughout the site. Actual subsurface conditions may differ, sometimes significantly, from those indicated in your report. Retaining the geotechnical engili).eer who developed your report to provide construction observation is the most effective method of managing the risks associated with unanticipated conditions.
B.2.6 A Report's Recommendations Are Not Final Do not overrely on the construction recommendations included in your report. Those recommendations are not final, because geotechnical' engineers develop them principally from judgment and opinion. Geotechnical engineers can finalize their recommendations only by observing actual subsurface conditions revealed during construction. The geotechnical engineer who developed your report cannot assume responsibility or liability for the report's recommendations if that engineer does not perform construction observation.
B.2.7 A Geotechnical Engineering Report Is Subject to Misinterpretation Other design team members' misinterpretation of geotechnical engineering reports has resulted in costly problems. Lower that risk by having your geotechnical engineer confer with appropriate members of the design team after submitting the report. Also retain your geotechnical engineer to review pertinent elements of the design team's plans and specifications.
Contractors can also misinterpret a geotechnical engineering report. Reduce that risk by having your geotechnical engineer participate in prebid and preconstruction conferences, and by providing construction observation.
B.2.8 Do Not Redraw the Engineer's Logs Geotechnical engineers prepare final boring and testing logs based upon their interpretation of field logs and laboratory data.
To prevent errors or omissions, the logs included in a geotechnical engineering report should never be redrawn for inclusion in architectural or other design drawings. Only photographic or electronic reproduction is acceptable, but recognize that separating logs from the report can elevate risk.
B.2.9 Give Contractors a Complete Report and Guidance Some owners and design professionals mistakenly believe they can make contractors liable for unanticipated subsurface conditions by limiting what they provide for bid preparation. To help prevent costly problems, give contractors the complete geotechnical engineering report, but preface it with a clearly written letter of transmittal. In the letter, advise contractors that the report was not prepared for purposes of bid development and that the report's accuracy is limited; encourage them to confer with the geotechnical engineer who prepared the report (a modest fee may be required) and/or to conduct additional study to obtain the specific types of information they need or prefer. A prebid conference can also be valuable. Be sure contractors have sufficient time to perform additional study. Only then might you be in a position to give contractors the best information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions.
B.2.10 Read Responsibility Provisions Closely Some clients, design professionals, and contractors do not recognize that geotechnical engineering is far less exact than other engineering disciplines. This lack of understanding has created unrealistic expectations that have led to disappointments, claims, and disputes. To help reduce the risk of such outcomes, geotechnical engineers commonly include a variety of explanatory provisions in their report. Sometimes labeled "limitations" many of these provisions indicate where geotechnical engineers' responsibilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely. Ask questions. Your geotechnical engineer should respond fully and frankly.
B.2.11 Geoenvironmental Concerns Are Not Covered The equipment, techniques, and personnel used to perform a geoenvironmental study differ significantly from those used to perform a geotechnical study. For that reason, a geotechnical engineering report does not usually relate any geoenvironmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated environmental problems have led to numerous project failures. If you have not yet obtained your own geoenvironmental information, ask your geotechnical consultant for risk management guidance.
Do not rely on an environmental report prepared for someone else.
