Mr. Michael Nixon P.E... via e-mail (mnixon@ircgov com) Roadway Production Manager Subject: Materials Testing and Observation Services Old Dixie Highway Resurfacing IRC Project No. 1137 Indian River County, Florida Dunkelberger Proposal No. PHB140131 (Revised 8-29-14) Dear Mr Nixon: As requested, Dunkelberger Engineering & Testing, Inc., A Terracon Company (Dunkelberger) is pleased to submit this revised proposal for Materials Testing and Observation Services during construction activities at the subject project in Indian River County, Florida A. PROJECT INFORMATION The subject project will include the reconstruction of the base course and asphaltic concrete structural course and shoulder widening of the of Old Dixie Highway from the IRFWCD North Relief Canal to 71st Street. The project length is approximately 11,270 lineal feet (2.13 miles) and the contract time is 150 calendar days to substantial completion. The reconstruction (resurfacing) will involve building a 9 -inch thick full -depth reclamation (FDR) base course, a 11/2 -inch thick asphaltic concrete (AC) structural course, and 1 %--inch thick AC wearing course. The shoulder widening will involve constructing a 12 -inch deep stabilization (LBR 40) 3 to 4 feet wide on each side of the existing roadway Also associated with the project is a minor amount of earthwork, drainage and concrete. The purpose of our work is to provide quality assurance (QA) testing and inspection to check the conformity of the materials composition and their construction with the project specifications. B. SCOPE OF SERVICES Based on our understanding of the project schedule and review of the project plans and specifications, we envision that our field sampling/testing and inspection services will be required over a period of approximately 50 working days for an average of 6 hours per day More specifically, our work will involve the following.

FDR Base Course • FDR mix design — Review and evaluate the mix design developed by the Contractor for its design approach and procedure. • Full Sieve Analysis test on the virgin materials before injection of emulsion at a frequency of 1 test every 1000 linear feet per lane (estimated total of 22 tests). • Maximum Density (Proctor) tests of the in-place FDR base materials at a frequency of 1 test every 1000 linear feet per lane (estimated total of 22 tests) • In-place density tests at a frequency of 1 test per 500 linear feet per lane (estimated total of 44 tests) • Verification of completed FDR base course — Review and evaluate the verification testing plan as well as the testing results as provided by the Contractor. Contactor QC Testing of the Asphaltic Concrete (AC) Pavement We understand that the Contractor is responsible for their own QC testing which shall include performing at least one set of asphalt lab tests per day to evaluate the materials produced for construction during paving. A minimum of three cores shall be cut by the Contractor on daily basis to evaluate the in-place (constructed) density of the structural course construction The cores shall be tested for bulk specific gravity, and the compaction will be evaluated based on the percentage of the bulk specific gravity over the maximum density determined in the plant on the bulk mix materials. As an option, the density (% compaction) of the wearing course construction may be evaluated using a calibrated nuclear gauge if a correction factor can be established using the core densities from the first day of wearing course paving. Dunkelberger will not be in the asphalt plant to perform any verification testing (VT) during asphalt production. Field Observation • Provide a full-time FDOT CTQP qualified technician to check the construction operations for conformance with the applicable project specifications. o FDR Construction — checking the depth of pulverization; checking the homogeneity of the FDR virgin mix (without emulsion); checking the moisture DUNKELBERGER Proposal for Materials Testing Services (Revised 8-29-14) Old Dixie Highway Resurfacing z Indian River County, Florida August 29, 2014 ii Dunkelberger Proposal No PHB 140131 Page 3 content of virgin mix prior to mixing with emulsion, verifying the type and source of the emulsion, keeping track of the consumption of the emulsion on a daily basis, verifying the application rate of emulsion in gallons per SY, and performing sampling periodically of FDR materials for laboratory testing, and field density testing on the constructed FDR base; and measuring cross slope and checking final grade of the constructed FDR base. • While on-site the technician will communicate with designated County and Contractor personnel so that items of concern or identified deficiencies can be immediately corrected. • Prepare field observation reports documenting the observed work effort and completed work areas, notable occurrences or specification deviations, weather conditions, field communications and other relevant activities. Engineering & Reporting • Engineering oversight during the construction to coordinate the aforementioned test program, make site visits, and attend progress meetings • Submittal of brief engineering reports documenting our findings and test results. Our materials and observation testing services will be provided on an as -needed basis as dictated by the pace and methods of construction. C.

SITE ACCESS AND SAFETY Page 4 Indian River County (IRC) shall secure all necessary site related approvals, permits, licenses, and consents necessary to commence and complete the services and will execute any necessary site access agreement. At Dunkelberger, we all have a personal and uncompromising commitment to everyone going home safely each and every day. Our safety program, Incident and Injury Free® is about care and concern for people. It is our personal and organizational commitment at all levels of the company and is where safety is held as a core value as well as an operational priority. Working safely is an inseparable part of working correctly, just as much as other operational priorities, in particular quality, profitability and schedule. IIF is our commitment to our people and others, who we value for who they are and what they do. IIF is not just something we do, it's in everything we do. As part of our IIF process, we will prepare a "Pre -Task Plan" to identify the potential site safety and job hazards associated with your site. Our Pre -Task Plan will identify and prepare our personnel to be able to handle conditions such as but not limited to traffic control, environmental contamination, site access issues, overhead and underground utilities, adverse weather conditions, and personal protection equipment and will continually be reviewed and reevaluated throughout the field work activities. We understand that each site is unique and may contain different safety conditions and as a company to protect our personnel as well as others, we look at each site individually to identify the potential concerns E. TESTING AND OBSERVATION The above services will be provided under an as -requested basis. Additionally, we request a 48-hour notice to schedule our services IRC understands that testing and observation are discrete sampling procedures, and that such procedures indicate conditions only at the depths, locations, and times the procedures were performed. Dunkelberger will provide test results and opinions based on tests and field observation only for the work tested IRC understands that testing and observation are not continuous or exhaustive, and are conducted to reduce — not eliminate — project risk. IRC agrees to the level or amount of testing performed and the associated risk. IRC is responsible (even if delegated to contractor) for notifying and scheduling Dunkelberger so Dunkelberger can perform these services. Dunkelberger shall not be responsible for the quality and completeness of IRC or its contractors work or their adherence to the project documents, and Dunkelberger's performance of testing and observation services shall not relieve contractor in any way from its responsibility for defects discovered in its work, or create a warranty or guarantee Dunkelberger DUNKELBERGER Proposal for Materials Testing Services (Revised 8-29-14) Old Dixie Highway Resurfacing t Indian River County, Florida August 29, 2014 w Dunkelberger Proposal No PHB 140131 Page 5 will not supervise or direct the work performed by IRC or its contractors and is not responsible for their means and methods.
