11TH DRIVE AND 37TH STREET ROADWAY AND INTERSECTION IMPROVEMENTS Page -2 IRC PROJECT No. 2001 RACE Proposal No. P23-2555 SCOPE OF SERVICES Based on our review of the Contract Plans (roadway) prepared by MBV Engineering, Inc. (dated October 2022) and the Contract Plans (signalization improvements) prepared by Kimley-Horn (dated April 2022) , we understand that required QC services will include the elements listed below: • Density testing for all embankment, subgrade and base rock used for roadway construction; • Density testing for all drainage improvements (including various conduits and utility deflections/conflicts); • Density testing of sidewalk, driveway and bus pad subgrade; • Concrete compressive strength testing for curbing, driveways, sidewalks, ADA ramps and drilled shafts; • Perform limited asphalt inspection and testing services, both in the field and at the plant; • Drilled shaft inspections and testing for the four mast -arm lighting assemblies and pols. Additionally, we will coordinate the inspection of signal pole anchor bolts and mast -arm connection bolts at each signal location (in general accordance with FDOT Standard Specification 649 (Galvanized Steel Poles, Mast Arms & Monotube Assemblies) and also FDOT's Standard Index 17745 (Mast Arm Assemblies). These services will be performed by our subconsultant, Johnson, Mirmiran and Thompson QMT); • Performing all necessary laboratory testing services to support the above -listed field testing services (e.g., Proctor, LBR, percent -fines, organic content, asphalt gradation/extraction, etc.). 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 approximately43$ ,851.00. 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 AACE, 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.
