As requested, we will perform the field work on a unit rate (per test) basis. As such, a four -test minimum charge per trip to the site will apply; sample pick-up will be performed at an hourly rate. A. PROJECT INFORMATION The subject project is located on 58th Avenue from 261h Street to 491 Street. The project will involve fulWepth reclamation (FDR) of the existing roadway, i.e., pulverization of the existing asphaltic concrete and base course, shoulder widening utilizing the reclaimed material, shoulder widening using traditional stabilization materials, and milling/resurfacing of select areas. The project length is approximately 11,800 lineal feet (2.25 miles). The contract duration is 270 days to substantial completion and 300 days to final completion. More specifically, the reconstruction will involve pulverization of 12 inches of existing roadway, construction of a 9 -inch thick FDR base course, and construction of three inches of asphalt pavement including a 2 -inch structural course and 1 -inch friction course. The shoulder widening will involve construction a 12 -inch thick FDR section ranging from Dunkelberger Engineering & Testing, Inc., A Terracon Co. 645 NW Enterprise Drive, Suite 107 Port St. Lucie, Florida 34986 P [772] 343 9787 F [772] 343 9404 terracon.com Proposal for Materials Testing Services Page 2 58th Avenue Resurfacing/Reclamation ■ Indian River County, Florida February 8, 2018 ■ Terracon Proposal No. PHB181012 2 to 7 -ft wide, as well as an unpaved 12 -thick stabilized shoulder on each side of the existing roadway. Also associated with the project is installation of approximately 224 lineal feet (If) of underground drainage pipe and two stormwater drainage structures. The purpose of our work is to provide quality assurance (QA) testing and inspection for the county to check the conformity of material composition with the project plans and specifications. B. SCOPE OF SERVICES Based on our understanding 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. Pipe Backfill, Shoulder Stabilization, Misc. Embankment • Laboratory Proctors (AASHTO T-180) to determine maximum density of the soils used for pipe backfill. • In-place density tests of embankment for backfill placed at a frequency of 1 test per 500 If. Compacted subgrade tests are not anticipated beneath the FDR base. • In-place density tests of pipe backfill at a frequency of one test per 500 If (or fraction thereof) for each 6 -inch 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 every 4,000 linear feet or 3 LBR samples on each side of roadway (total of 6 tests). • In-place density tests of the LBR Shoulder Stabilization at a frequency of 1 test per 2,000 linear feet each side of roadway (total of 12 tests). FDR Base Course • FDR mix design — Review and evaluate the mix design developed by the Contractor for its design approach and procedure if requested by the County and if provided to us for review prior to construction. • Sieve Analysis test on the virgin materials before injection of emulsion at a frequency of 1 test every 1,000 linear feet per lane (estimated total of 24 tests). • Maximum Density (Proctor) tests of the in-place FDR base materials at a frequency of 1 test every 1,000 linear feet per lane (estimated total of 24 tests) • In-place density tests at a frequency of 1 test per 500 linear feet per lane for mainline and 1 test per 2,000 If for shoulder (estimated total of 112 tests).
