As requested, we will perform the field work on a unit rate (per test) basis instead of an hourly basis. As such, a four test minimum charge per trip to the site will apply. 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 71st Street to CR 510. The project length is approximately 10,070 lineal feet (1.9 miles). The contract duration is unknown to us at this time. The reconstruction (resurfacing) will involve building a 9-inch thick full-depth reclamation (FDR) base course, a 1'/2-inch thick asphaltic concrete (AC) structural course, and 1'/2- 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 installation of approximately 4,951 lineal feet (If) of drainage pipe, 28 inlet structures, 144 If of box culvert, and construction of four concrete endwalls. The purpose of our work is to provide quality assurance (QA) testing and inspection to check the conformity of material composition with the project specifications.

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 services will be required on a periodic or as needed basis over the duration of the project. More specifically, our work will involve the following. Earthwork— Embankment and LBR 40 Shoulder Stabilization • Laboratory Proctors (AASHTO T-99 and T-180) to determine maximum density of the soils used for embankment and pipe backfill. • In-place density tests of embankment at a frequency of 1 test per 500 If. • In-place density tests of pipe backfill at a frequency of one test per 500 If (or fraction thereof) for each lift of backfill placed. • Limerock Bearing Ratio (LBR) tests of the in-place LBR materials for the Stabilized Shoulders at a frequency of 1 test about every 2000 linear feet or 5 LBR samples on each side of roadway (total of 10 tests). • Thickness verification of completed 12" LBR Shoulder Stabilization. • In-place density tests of the LBR Shoulder Stabilization at a frequency of 1 test per 500 linear feet each side of roadway (total of 42 tests). 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 42 tests). • 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. • Verification of completed FDR base course — Review and evaluate the verification testing plan as well as the testing results as provided by the Contractor. • As a contingency, we have listed our laboratory testing rates for FDR Mix Design Verification and Resilient Modulus testing in case the contractor's QC laboratory cannot provide these services. 1 rerralc®n Proposal for Materials Testing Services Page 3 Old Dixie Highway Resurfacing ■ Indian River County, Florida March 2, 2016 ■ Terracon Proposal No. PHB161007 Contractor QC Testing of 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 laboratory tests per day to evaluate the materials and 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 will 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 Terracon will not be in the asphalt plant to perform any verification testing during asphalt production. Engineering & Reporting • Engineering oversight and review 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 testing services will be provided on an as-needed basis as dictated by the pace and methods of construction. C. COMPENSATION The material testing services provided will be billed in accordance with our current 2014-2016 Continuing Geotechnical Services Agreement the line item unit rates illustrated on the Projected Scope and Budget (Attachment A). As stated earlier a four test minimum charge per trip to the site will apply. Terracon proposes to complete the scope of services as described herein for an estimated fee of $37,860 and invoiced on a unit rate basis. If additional services outside the listed project services are required, Terracon will provide such under auspice of a Supplemental Proposal using the same line item unit rates as provided herein. The quantity of the work performed and factors beyond our control, such as weather and the contractor's schedule/efficiency, will affect the actual cost for our services. You will be invoiced at regular intervals but not less than monthly for services performed. lrerracon Proposal for Materials Testing Services Page 4 Old Dixie Highway Resurfacing ■ Indian River County, Florida March 2, 2016 o Terracon Proposal No. PHB161007 Invoices for our services will be directed to the addressee of this letter unless we are directed otherwise.
