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
