Mr. Tony Buonodono, PE, PMP AG1413700 June 13, 2014 (Revised October 14, 2014) Classification Tests including water content, particle size gradation (sieve and hydrometer analyses), Atterberg Limits determinations, and Unconfined Compression Tests. Results of the field and laboratory data will be used to develop a geotechnical data report for the proposed water lines. In general, the following items will be included in the report: The following items will be included in the HVJ data report: 1) Vicinity Map 2) Geology Map of the Project Site 3) Plan of Borings 4) Boring logs including laboratory test results 5) Laboratory test results summary 6) Particle size gradation charts The following items will be included in the HVJ design report: 1) Backftll and bedding recommendations 2) Particle migration recommendations 3) General discussion of construction recommendations A report of our study will be prepared by an engineer specializing in soil mechanics and foundation engineering after reviewing available design, boring and laboratory data. Assumptions Following assumptions were made in developing the scope and fee estimate for this project: • No site clearance will be required to access the borehole locations • HVJ Associates will only be responsible for City of San Marcos (COSH) street cut permits and Hays County street cut permits. • Pavement and geotechnical slope stability design recommendations are not part of the scope of this study. • Klotz will provide HVJ with an electronic site map prior to the initiation of the field investigation with boring locations. • Survey of boring locations will be done by others, if required. • We have assumed drilling will take place during weekdays between 9AM to 4PM, nighttime and /or and weekend drilling was not included in this estimate. Fee Based on the scope of work outlined, the combined fee for our services will be $6,570.29 A cost breakdown is attached to this proposal. If anomalous soil conditions are encountered, or if the project configuration changes significantly, additional work may be required HVJ Associates, Inc. will recommend such additional work when and if it is deemed necessary. Schedule We propose to start fieldwork one week after receiving a written notice to proceed and expect to complete fieldwork within four weeks of receiving all of the required permits. Any delays such as difficulty of obtaining COSM street cut /Hays County Street permits, or inclimate weather will be communicated to Klotz and may alter the fieldwork project schedule.
