Kafer Jr., P.E. County Engineer December 22, 2014 AACE Proposal No. P14-392 PROPOSAL FOR CONSTRUCTION MATERIALS TESTING INDIAN RIVER COUNTY INTERGENERATIONAL RECREATION CENTER INDIAN RIVER COUNTY, FLORIDA Per your request, Andersen Andre Consulting Engineers, Inc. (AACE) is pleased to present this proposal for performing construction materials testing for Indian River County's proposed Intergenerational Recreation Center located in Vero Beach, Florida. Based on our review of the Civil Plans prepared for the subject site by Masteller & Moler, Inc. (M&M) dated November 12, 2014 and provided to us by the County, we understand that the proposed recreational facility will be constructed on approximately 12 acres of the 75.11 -acre County -owned parent tract located at the northeast corner of Oslo Road and 20`h Avenue. This phase of the project (Phase I) includes the construction of a 37,753 square -foot recreation building, approximately 140,000 square feet of paved parking, a two -cell stormwater management pond (separated by a httoral planting area) and two dry retention ponds, as well as an outdoor event lawn, various patio areas, sidewalks and entranceway features. Additional project elements include drainage improvements and utility installations. Based on our review of M&M's Paving and Grading plans, it appears that approximately 3-4 feet of fill will be needed to raise the site to proposed grades. We understand that the services for which we are preparing this proposal include density testing of all soil and base rock as well as concrete testing associated with site work activities, and also for vertical construction. For the purposes of this proposal, we have separated our services (and costs) as follows: Site Work ► Density testing for building pads, parking lot, roadways, utility and stormdrain excavation backfill, sidewalk, and patio subgrade; ► Compressive strength of concrete testing for sidewalks and curbing; Vertical Construction ► Density testing for building footings, conduit backfill, etc.; ► Compressive strength of concrete testing for building construction and pads, 573 SW Biltmore Street, Port St. Lucie, Florida 34983 Ph: 772-807-9191 Fx: 772-807-9192 www.aaceinc.com Intergenerational Recreation Center Page -2- AACE Proposal No. P14-392 Based upon our cursory review of the project plans and our prior experience in the area and with sites and projects similar to this one, we estimate the cost of testing services will be $57,115.00 (itemized on pages 3 through 5). The actual cost of AACE's testing services will be a function of work actually performed in accordance with the attached unit fee schedule (per the Continuing Service Contract between Indian River County and RACE). 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. To authorize us to proceed with this project, please execute and return to us a copy of the attached Professional Services Agreement form or a Purchase Order number. If you have any questions or if we can provide any additional information, please feel free to contact us at your convenience. Best Regards, ANDERSEN ANDRE CONSULTING ENGINEERS, INC.

Conduit Trench Backfill; 25 density tests @ $23 00/test $575.00 Concrete Testing. It is difficult to accurately predict the number of concrete specimens needed for QA/QC for a project such as the Intergenerational Recreation Center since the number of tests is largely based on the number of pours (i.e., 1 set of cylinders for a 50 cubic yard pour vs. 5 sets of cyhnders for five separate 10 cubic yard pours, etc.). Without knowing the Contractor's methodology or pour schedule for this work element, we largely base the concrete testing budget on our expenence with similar projects. For this purpose, we have assumed the following. (1) Tilt -Up Panels: 86 panels (avg. width/height: 30'/20' x 4" = 7.5 yd3 per panel, pouring 10 panels/day, 2 sets of specimen/pour) ► 20 sets of 4 cyhnders for compressive strength testing @ $85.00/set $1,700.00 (2) Recreation Center Columns. ► 5 sets of 4 cylinders for compressive strength testing @ $85.00/set $425.00 (3) Recreation Center Slab (Assume 4 pours, 2 sets/pour) ► 8 sets of 4 cylinders for compressive strength testing @ $85.00/set $680.00 (4) Semor Technician for Standby during larger pours, extra slumping, etc. ► 25 hours @ $55.00/hour $1,375 00 Vertical Construction Testing Subtotal: $6,365.00 TOTAL ANTICIPATED TESTING BUDGET (SITE WORK + VERTICAL) $57,115.00 Intergenerational Recreation Center Page -6- AACE Proposal No. P14-392 The following conditions apply to this project: (1) A minimum of 4 density tests or 1 set of concrete testing will need to be performed per hour, per visit to the site. (2) Stand-by time will be charged at $55.00/hour per technician. (3) We note that density testing frequencies are approximate and based on our experience with similar projects and anticipated contractor methodologies. Allowances for re -tests (from failing density tests) are not included herein. (4) The contractor should contact Andersen Andre Consulting Engineers, Inc. at (772) 807-9191 a minimum of 24 hours prior to any testing and 48 hours pnor to weekend and evening work. Unit rates apply to standard working days, Monday through Friday, 7:00 a.m to 6:00 p.m. Testing and hourly rates will be increased by 50% for weekend, holiday or after-hours services. (5) (6) The following testing costs are not included within this estimate: costs associated with asphalt testing (either in the field or laboratory) or bacteriological testing of potable water (bac-t's). Such testing can be performed if requested using the rates included herein. (7) If our testing estimate for a specific work element is insufficient for that particular activity, resources from another work element can be used without prior authorization from the client as long as our total cost esumate is not exceeded. We will notify you in advance if it appears that the cost estimate presented in the attached unit fee schedule will be exceeded. (8) Soil sample pickup for laboratory testing (e.g., Proctor testing) will be billed at $55.00/hour if not scheduled with other work. (9) We note that the number of sets of concrete cylinders is dependent on numerous factors, such as the size and duration of pours. For example, if numerous "smaller" pours (e.g., 10 -yard pours) occur during construction, our estimate for the number of sets of concrete cylinders may be exceeded, thus requiring revision of this proposal to account for this testing cost increase. (10) No paint -thickness or fire proofing thickness testing, bolt -tightness, steel or weld inspections, or floor levelness testing are included herein; we would be pleased to revise this proposal to include such services if requested.
