AACE <br />ANDERSEN ANDRE CONSULTING ENGINEERS, INC. <br />Geotechnical Engineering <br />Construction Materials Testing <br />Environmental Consulting <br />Indian River County, Engineering Division <br />1801 27th Street <br />Vero Beach, Florida 32960 <br />Attention: Mr. William Johnson, P.E. <br />Roadway Production Engineer <br />EXHIBIT 'A' <br />PROPOSAL FOR CONSTRUCTION MATERIALS TESTING SERVICES <br />45TH STREET BEAUTIFICATION PROJECT PHASE II <br />IRC -1748 <br />INDIAN RIVER COUNTY, FLORIDA <br />AACE Proposal No. P18-1037 <br />April 12, 2018 <br />Revised November 6, 2018 <br />Revised February 11, 2019 <br />As requested, Andersen Andre Consulting Engineers, Inc. (AACE) is pleased to present this cost estimate for construction <br />materials testing services relative to the 45th Street (aka Gifford) Beautification Project (Phase II). Based on our review of the <br />Construction Plans for the project prepared by Kimley-Horn (dated March 2018), it is our understanding that the project <br />consists of piping an open canal for an approximate distance of approximately 4,000 LF. The canal is located on the south side <br />of 45th Street and ranges in depth from approximately 6 to 10 feet deep. It will be necessary to over -excavate portions of the <br />canal to accommodate the RCP (36" to 84"), and perhaps widen the canal for the purpose of installing 3,600 LF of Type II <br />underdrain. Other project elements that will require testing include roadway restoration, utility installations and sidewalk <br />construction. <br />Unless otherwise communicated to us, we anticipate that our role for the project will include the following <br />1. Performing density testing for storm drain piping backfill, water main trench backfill, roadway restoration and for <br />sidewalk subgrade; <br />2. Performing laboratory testing of soils and base rock (e.g., Proctor and LBR sampling); <br />3. Performing compressive strength testing of concrete useed in sidewalk construction. <br />Based upon our understanding of the project plans and our prior experience with projects similar to this one, we estimate the <br />cost of the services will be approximately $36,215.00. The actual cost of AACE's testing services will be a function of work <br />actually performed in accordance with the attached unit fee schedule (in accordance with the continuing service contract between <br />Indian River County and AACE, Contract #2018042). Contractor efficiency, methodology and changes in testing frequencies <br />may affect the testing cost. We will notify you in advance if it appears that the cost estimate will be exceeded. <br />If the terms above are acceptable to you, please sign and return the Professional Services Agreement as an indication of your <br />acceptance and authorization to proceed with the work. Please contact us if you should have any questions concerning this cost <br />estimate. <br />Best Regards, <br />ANDERSEN ANDRE CONSULTING ENGINEERS, INC. <br />David P.
