DocuSign Envelope ID: C28BF39E- EOF1- 42FB- 9F5B- 93F375B7013B <br />Proposal for Construction and Materials Testing Services Irerracan <br />Sportsplex Field House a 101 Meadowlands drive Hillsborough, NC 27278 <br />February 20th, 2018 a Terracon Proposal No. 70171288 <br />B. SCOPE OF SERVICES <br />The services to be provided by Terracon are summarized in the following paragraphs. <br />1. Earthwork and Site Preparation: <br />Observe subgrade conditions and proofrolling of subgrades in initial fill areas prior to <br />beginning fill placement. <br />Observe and test structural fill placement and perform field density and moisture <br />content testing during fill placement and during utility backfilling in the proposed <br />building area. Field density (compaction) tests will generally be performed at <br />approximate: <br />0 1 -foot or less of vertical intervals and for every 5,000 sf in the building area. <br />c 1 -foot or less of vertical intervals and for every 10,000 sf in the paved areas. <br />71 Perform laboratory moisture- density relationship, grain size analysis and Atterberg <br />Limits on proposed fill soils. <br />.1 Perform laboratory testing of proposed fill soils to determine their dry density versus <br />moisture content relationship in general accordance with the standard Proctor test <br />method. <br />A Senior Engineer or Project Manager will attend necessary meetings, when <br />requested, and be available to visit the site during site work activities to provide <br />technical support at critical stages and/or to address problems that may arise. A <br />Project Engineer will coordinate our personnel and review daily reports prior to final <br />Issue. <br />It is important to note that the natural geology within portions of the site has been <br />modified in the past by grading that included the placement of fill materials The quality <br />of man -made fills can vary significantly, and it is often difficult to assess the <br />engineering ro erties of existing fill. <br />Based on the Geotechnical Engineering Report by ECS, dated 8/23/2013, after site <br />stripping, its recommend to have a representative of the geotechnical engineer <br />observe a Proofroll of the site with a loaded dump truck, having an axle weight of at <br />least 10 tons or similar rubber -tired construction equipment after suitable period of dry <br />weather to avoid degrading an otherwise acceptable subgrade. Areas exhibiting rutting <br />or deflection should be repaired as recommended by the geo engineer. Repairs <br />typically consist of over- excavating soft and unsuitable soils followed by replacement <br />with compacted engineer fill. Some over - excavation and replacement may be required <br />following proofrolling operations. <br />Highly plastic silts were encountered in Boring B -3 to a depth of 3 feet below the <br />existing grade. This soil may require moisture adjustments, localized undercutting and <br />replacement or other appropriate remedial activities if they exist at the finished <br />elevation due to potential shrink/swell. It is desirable to maintain at least 2 to 3 feet of <br />separation between the bottom of foundations, slabs and pavement sections and <br />these soils to help reduce the potential for premature distress of as -built construction <br />Responsive a Resourceful a Reliable 2 <br />
