TOWN OF FIRESTONE, BY: obbi Sindelar, Mayor ATTEST:,I�Y(.�4C(�Y1�(�� dyff Leah Vanarsdall, Town Clerk CONSULTANT: CESARE, INC. a Colorado corporation, By: Title: Principal Engineer AIVED AS TO FORM: William P. Hayashi, Town Attc Date: August g 2019 EXHIBIT A c Ms, Lindsey Green Colorado Civil Group, Inc. 2204 Hoffman Drive Loveland, CO 80538 JUIy 23, 2019 Revised July 31, 2019 Subject: Proposed Geotechnical Study Berwick Avenue (between Florence Avenue and Farmdale Street) Firestone, Colorado Proposal Agreement No. F190709 Dear Ms. Green: Cesare, Inc. (Cesare) is pleased to submit this proposal to the Town of Firestone for a geotechnical study on a section of Berwick Avenue between Florence Avenue and Farmdale Street. The asphalt pavement has developed distress in some areas of the street. This section of residential street is approximately 500 feet in length consisting of two traffic lanes. The purpose of this investigation will be to obtain subsurface data to help evaluate the probable causes of the severe pavement distressed observed. Two test holes will be performed to provide some useful information about the existing pavement section, soil classifications, moisture contents, engineering properties of the subsoils and possible depths to water. The information obtained will allow us to offer an opinion about the primary reasons for the pavement failure and present some guidance for a suitable repair or replacement section. Based on the existing data and our understanding of the project requirements, we propose the following scope of services: 1. Contact the Utility Notification Center of Colorado (811) to have publicly owned utilities identified and marked prior to performing any drilling or excavation in the street. The Client/Owner is responsible for having the locations of any private utilities or subterranean structures identified and clearly marked prior to Cesare initiating drilling or excavation services. 2. Drill a total of 2 borings in Berwick Avenue, both to be located adjacent to areas of distress. Borings will be drilled to depths of about 5 to 10 feet below the existing ground surface. This proposal is based on the site being accessible by a standard truck mounted, rubber tired drill rig, equipped with continuous flight, solid stem auger. In the event site access or difficult drilling requires use of a different rig or drilling equipment, additional costs will apply. This proposal assumes right of way permitting will either not be required or will be provided by the client. 3. Perform penetration resistance tests on the in -place soil/bedrock during drilling to help identify pertinent material layers and obtain samples of the materials encountered. CESARE, INC. 4. Check for the presence of groundwater in our borings during drilling and once within 3 days after drilling. Cesare will leave both of the borings open but covered with steel plate to allow for water checks. 5. Backfill all borings with cuttings/spoils obtained from the borings and/or other suitable materials upon completion of the last groundwater level check. Borings will be surface patched with cold -patch asphalt mix. 6. Conduct laboratory testing to classify and characterize the soil/bedrock materials encountered in the borings. Testing may include grain size distribution, plasticity, natural moisture content and density, swell -consolidation and R-value. 7. Present interim data verbally as the field and laboratory study progresses, if requested. 8. Evaluate the data obtained from field investigations and laboratory testing. 9. Perform data review of existing pavement for information that includes history of pavement design through construction and recent repairs. 10. Summarize the field and laboratory data and present results of our evaluation and analyses in an engineering report that will include: a. A site plan showing the existing site and locations of borings; b. Summary logs of the borings that show existing pavement and road base thickness, soil/bedrock types encountered, locations and types of samples obtained, results of penetration tests performed, and groundwater levels; c. Laboratory test results in graphic and tabular form; d. Descriptions of existing site conditions; e. Opinions on sources) of pavement distress and failures; f. Repair/replacement recommendations. g. Surface drainage precautions. 11. Submit the geotechnical study report in electronic format (pdf) signed by a Colorado registered professional engineer upon completion of these services. Printed copies will not be provided unless specifically requested prior to report preparation. Additional fees will apply if printed copies are requested. Cesare will perform the proposed services on a time and materials basis for an estimated fee of $2,200. ADDITIONAL SERVICES Should it become necessary to revise the scope of services from that described herein, Cesare will revise the estimates/fees provided herein accordingly and submit for written authorization prior to performing the revised scope. Consultation, engineering, and/or additional testing required or requested to be performed after submittal of our report (draft or final) will be invoiced at the hourly and/or laboratory testing rates listed in our schedule of fees. The proposed services will require drilling through existing pavement. Cesare will repair the pavement with cold patch. If the Client/Owner requires and requests repair beyond this, Cesare will submit a separate proposal for the cost of conducting the requested repair. 2 SCHEDULE OF FEES Senior Principal................................................."give.......................... $185/hour Principal........................................................................................... $165/hour Senior Consultant.... 0064 womsbAl I 1 5044460 60440466sa RAO to $150/hour Senior Project Engineer or Senior Project Geologist ............................. $130/hour Senior Project Manager. .
