69TH STREET Page -2- FM No. 438073-1-54-01 IRC PRojEcr No. 1639 AACE Proposal No. P22-2311 SCOPE OF SERVICES Based on the FDOT's Developmental Specification T332 and on our experience with similar projects (including 58 h Avenue), we understand that required QC services will include the elements listed below: Field and Laboratory Testiniz of FDR Roadway Base and Shoulders: - Obtaining samples of pulverized road base for laboratory gradation testing at a frequency of one sample for every 2,000LF per lane, or as needed. - Obtain samples of the FDR mix for laboratory Marshall Stability testing every 2,000LF per lane, or as needed. - Obtaining one sample for laboratory moisture/density relationship testing at a frequency of one sample for every 2,000LF per lane, or as needed. - Performing one in-place field density test for every 50OLF of the compacted mixture on days selected by IRC staff (or as otherwise requested by IRC staff). - Obtaining composite samples of the Refurbished Stabilized Shoulders and widened areas at a frequency of one sample for every 2,000 LF for laboratory Limerock Bearing Value (LBR) testing, or as needed. - Obtaining composite samples of the FDR mix at a frequency of one sample for every 2,000 LF for laboratory Limerock Bearing Value (LBR) testing, or as needed. - Performing in-place density testing of shoulder stabilized subgrade (approximately one (1) test per every 2 LOTS of shoulder (about 1,000 LF), each direction or at the direction of the County. - Performing in-place density testing of embankment, as needed. QC services during paving operations: - Performing asphalt plant inspection services during three (3) paving operations (selected by IRC). - Obtaining roadway cores on four (4) occasions after paving operations for specific gravity (density) determination (estimated three (3) cores obtained during each event). - Obtaining a maximum of four (4) bulk samples of asphalt for asphalt content and gradation testing. Drainage Construction: - Performing in-place density testing of soil used to backfill all drainage excavations Miscellaneous Testine - Performing concrete testing services for non-structural concrete (sidewalks and ADA ramps, curbing, headwall, bus shelter pad, and driveways). - Perform density testing for general restoration and corrective construction (driveway restoration, sidewalk subgrade, utility and hydrant relocations, etc.) We note that no field and/or laboratory testing of the FDR mix is included herein for the purpose of confirmin¢ that a Structural Number of 1.8 has been achieved. We understand that such testing will be the responsibility of the Contractor's testing consultant. Based upon our understanding of the project plans and our prior experience with projects similar to this one, we estimate the cost of the services will be approximately $46,510.00. The actual cost of AACE's testing services will be a function of work actually performed in accordance with the attached unit fee schedule (in accordance with the continuing service contract between Indian River County and RACE, Contract #20211207). Contractor efficiency, methodology and changes in testing frequencies may affect the testing cost. We will notify you in advance if it appears that the cost estimate will be exceeded. - Balance ofpage intenhonalyleft blank -
