Home My WebLink AboutappendixBAPPENDIX B Important Information About Your Gootocboical Engineering Report Subsurface problems are a principal cause of construction delays, cost overruns, claims, and disputes. The following information is provided to help you manage your risks. Gootechnlcal Services Are Performed for Specific Purposes, Persons, and Projects Geotechnica€ engineers structure their services to meet the spe- cific needs of their clients. A geotechnical engineering study con- ducted for a civil engineer may not fulfill the needs of a construc- tion contractor or even another civil engineer. Because each geot- echnical engineering study Is unique, each geotechnlcai engi- neering 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 pre- pared it. And no one —not even you —should apply the report for any purpose or project except the one originally contemplated. Read the full report Serious problems have occurred because those relying on a geotechnical engineering report did not read It eli. Do not rely on an executive summary. Do not read selected elements only. A Geotechnlcal Engineering Report Is Based on A Unique Sot of Project -Specific Factors Geotechnlcal engineers consider a number of unique, project -spe- cific factors when establishing the scope of a study. Typical factors include: the client's goals, objectives, and risk management pref- erences; the general nature of the structure Involved, Its size, and configuration; the location of the struoture 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 other- wise, do not rely on a geotechnical engineering report that was: • not prepared forlou, • • 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 rellability 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. Geotechnlcal engineers cannot accept responsibility or liability for problems that occur because their reports do not consider developments of which they were not informed, 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 geotecftnical engineering report whose adequacy may have been affected by: the passage of time; by manmade events, such as construction on or adjacent to the site; or by natural events, such as floods, earthquakes, or groundwater fluctua- tions. Always contact the geotechnical engineer before apply- ing the report to determine if it is still reliable. A minor amount of additional testing or analysis could prevent major problems. Most Geotechnlcal Findings Are Professional Opinions Site exploration identifies subsurface conditions only at those points where subsurface tests are conducted or samples are taken. Geotechnlcal engineers review field and laboratory data and then apply their professional judgment to render an opinion about subsurface conditions throughout the site. Actual sub- surface conditions may differ -sometimes significantly —from those Indicated in your report, Retaining the geotechnical engi- neer who developed your report to provide construction obser- vation is the most effecth+e method of managing the risks asso- elated with unanticipated conditions. 1 UES Project No.: 67905-001-01 UES Report No.: 9217 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. B-2 UES Project No.: 87905.001-01 UES Report No.: 9217 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. !f any changes In the design or location of the structure as outlined in this report are planned, or if any structures are Included or addod 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. 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 Togs 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. B-3 UES Project No.: 67905-001-01 UES Report No.: 9217 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 interprctations made in thls 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 investigation. if the report is not used in a reasonable amount of time, significant changes to the site may occur and additional reviews may be required.
