The purpose of the supplemental services and testing is to further investigate the potential for voids to exist in the vicinity of a buried water line beneath the east approach embankment after the line ruptured on February 12, 2009 The services will be provided under Local Agency Agreement Number 5632 between the City of Kent and GeoEngineers SCOPE OF SERVICES Our services will include additional consultation, attending meetings, and performing geophysical testing using ground penetrating radar(GPR)to check for presence of voids 1. Perform CPR testing of the wall face and along the toe of the wall in the vicinity of the line break. 2. Prepare a written report of our findings and conclusions including recommendations for repair as necessary and appropriate. CPR testing is scheduled for Wednesday, March 4,2009. Evaluation of the results and preparation of our report should be complete by March 13, 2009.

The objectives of the study are to assist in evaluating the conditions of fill materials behind the brick wall after a water pipe broke The pipe line runs parallel to the wall and approximately 15 ft below the ground surface outside the wall SCOPE OF WORK We propose to use ground penetrating radar for this study. 200 MHZ, 500 MHz, and 900 MHz antennas will be used for different penetration and resolution.Three horizontal lines (100 ft length, 4-5 ft apart and parallel to the ground surface) on the wall and three vertical transects (10-20 ft length) will be surveyed to evaluate the integrity of the fill materials behind the wall at the place where the water pipe broke METHODOLOGY,INSTRUMENTATION AND FIELD PROCEDURES The GPR method uses electromagnetic pulses, emitted at regular intervals by an antenna to map subsurface features The electromagnetic pulses are reflected where changes in electrical properties of materials occur such as changes in lithology or where voids are present. The reflected electromagnetic energy is received by an antenna, converted into an electrical signal, and recorded on the GPR unit The data is recorded and viewed in real time on a graphical display that depicts a continuous profile or cross-section image of the subsurface directly beneath the path of the antenna. The depth of penetration of the GPR signal varies according to antenna frequency and the conductivity of the subsurface material. The depth of subsurface penetration decreases j with an increase in the frequency of the antenna and an increase in soil conductivity, Global Geophysics GeoEngineers March 2,2009 Mr Garry Squires 2 093-0228.000 The data at this site will be collected using Geophysical Survey Systems, Inc. (GSSI) SIR 2000 GPR system with antennas having a center frequency of 200 MHz, 500 MHz and 900 MHz. DELIVERABLES Deliverables will include a brief letter report describing the instrumentation and field procedures. GPR transects with interpretations will be presented. COST The estimated costs of the survey are $3815.00, which includes mob/demob, car and equipment rental,field surveys, data processing and reporting. LIMITATIONS OF THE GEOPHYSICAL METHODS Global Geophysics's services are conducted in a manner consistent with the level of care and skill ordinarily exercised by other members of the geophysical community currently practicing under similar conditions subject to the time limits and financial and physical constraints applicable to the services. Ground penetrating radar is a remote sensing geophysical method that may not detect subsurface features Furthermore, it is possible that anomalies on the geophysical data that are interpreted to be of interests may upon intrusive sampling prove to be misinterpreted. AUTHORIZATION Global Geophysics is pleased to present this proposal and we look forward to your favorable response. If you have any questions or require additional information,please contact us at 425-890- 4321. Sincerely, Global Geophysics �4 John Liu, Ph D.,R G.
