Fax 913.492.7443 www.terracon.com We are pleased to submit our proposal to provide geotechnical engineering services for the referenced project. Our understanding of the proposed project and our proposed scope of services are described herein. Our estimated fee for this project is attached. If we have misunderstood any aspect of the proposed project, please advise us at once so we can evaluate the scope of services we have proposed. PROJECT INFORMATION We understand that the project involves a new stacked gabion retaining wall. Specific details regarding the new walls were not provided. PROPOSED SCOPE OF WORK Utility Locations We will contact a utility locate service to have underground public utility lines located and marked. It normally requires 2 to 3 business days to have utilities located. Sometimes, utility companies ask us to meet with them on site to show them where we plan to drill. If available, plans showing the locations of all public and private utilities should be provided. Boring LocationslElevations Terracon personnel will locate by estimating distances and right angles from existing site features. Distances between borings will be estimated based on mapping features shown on the plans provided to us. If requested, we can interpolate elevations from available topographic information. If more precise locations and elevations are required, a land surveyor should locate borings and determine elevations. Subsurface Exploration We understand that the site is accessible. We plan to use atruck-mounted drill rig to perform the borings. TranSystems has requested two (2) boring locations for the retaining wall. We plan to advance the borings to depths of 20 feet or practical auger refusal, whichever occurs first.

If subsurface conditions are encountered which would merit alteration of the field boring andlor sampling programs described above, we will contact you. Laboratory Tests In the laboratory, unconfined compression, calibrated penetrometer, water content, and dry density tests will be performed on representative samples extracted from the thin-walled tubes. Water content tests will be performed on split-barrel samples. Soil samples will be visually classified in accordance with the Unified Soil Classification System (USCS). Engineering Services After completion of exploration and laboratory testing, the data and conditions would be analyzed and a report will be prepared by or under the supervision of a registered professional engineer. The, geotechnical report will contain a description of the project, a summary of the drilling, sampling, and testing procedures and logs of the borings with laboratory test results. The report will present professional opinions and recommendations concerning the following: Foundation design parameters (allowable bearing pressure, estimated settlement, frost depth and minimum sizes). Lateral earth pressure and friction resistance considerations, as applicable. Global Stability Analysis, if requested. This proposal has been prepared in accordance with generally accepted geotechnical engineering practices. We understand this proposal letter and fee estimate schedule will be attached to a task order and will be performed under the Continuous Services Subcontract Agreement between TranSystems and Terracon dated December 21, 2005. We look forward to working with you on this project. If you have any questions, please contact us. Sincerely, -- / ~~ , r i~" ~ ~, ,i Jaryfes M. andrum, P.E.
