Indian River Boulevard Resurfacing October 24, 2022 <br />Proposal No. 18-7910.02 REVISED 3 <br />1. CONSTRUCTION MATERIALS TESTING <br />The services described herein will be performed as required by the construction documents and local <br />jurisdictions. Please note that the overall cost of construction quality control programs is dependent upon the <br />contractor's scheduling, weather and other factors beyond our control. In general, the scope of services will <br />consist of the following: <br />1.1 Laboratory Soil Testing <br />Laboratory soil testing will be required to identify the properties and suitability of the soil to be used at the site. <br />Proctor tests will be required to obtain material's maximum density and optimum moisture content, which would <br />be used to verify that the degree of compaction in the field is achieved. <br />1.2 Field Density/Moisture Testing <br />GFA will provide a field technician to test the in-place density of the compacted fills. For this testing, GFA will <br />use the Nuclear Method (ASTM D6938) in the field, which will be correlated with the corresponding laboratory <br />proctor compaction tests. <br />1.3 Cast -in -Place Concrete <br />GFA will provide testing of the concrete delivered to the site. In accordance with the project specifications, the <br />technician will mold a set of five compression cylinders per ASTM C-31 for every 50 cubic yards or fraction <br />thereof placed per day. GFA will also determine the slump and temperature of the concrete each time a set of <br />cylinders are cast <br />The cylinders will be cured in the laboratory, with one cylinder tested at seven days and three at 28 days. GFA <br />can also assist in evaluating mix submittals and provide laboratory verifications, if necessary, although fees for <br />this service are not included herein. <br />1.4 Schedule of Fees <br />The actual cost of our services will be highly dependent on the construction schedule. As we have not been <br />provided with a precise construction schedule, it is not possible to make a precise estimate of the manpower and <br />testing requirements. Therefore, GFA proposes to provide its services on a unit cost basis; based on the actual <br />work performed and the unit fees shown on the attached Schedule of Fees. For your budget purposes, GFA <br />has estimated quantities for these services based upon the anticipated scope of work. <br />02020 GFA International, Inc. All Rights Reserved.
