City of Arden Hills <br /> Proposal QTB134946 <br /> March 11, 2021 <br /> Page 3 <br /> ■ Review test reports, and communicating with you and the parties you may designate such as <br /> the project contractor(s), and other project team members, as needed. <br /> ■ Transmit test results to the project team on a weekly basis. <br /> Basis of Scope of Work <br /> The costs associated with the proposed scope of services were estimated using the following <br /> assumptions. If the construction schedule is modified or the contractor completes the various phases of <br /> the project at different frequencies or durations than shown in this proposal, we may need to adjust the <br /> overall cost accordingly. The scope of work and number of trips required to perform these services are as <br /> shown in the attached table. Notable assumptions in developing our estimate include: <br /> ■ We assume compaction testing will be performed using the nuclear density method on <br /> subgrade preparation, select granular embankment and utility trench backfill; a minimum of <br /> three tests will be conducted each trip with twelve trips assumed for utility trench backfill; a <br /> minimum of five tests will be conducted each trip with six trips assumed for subgrade <br /> preparation; a minimum of five tests will be conducted each trip with six trips assumed for <br /> select granular embankment. <br /> ■ We assume compaction testing on aggregate base material will be performed using the <br /> Dynamic Cone Penetration (DCP) method; a minimum of six tests will be conducted each trip <br /> with four trips assumed. <br /> ■ We assume sixteen sets of concrete tests will be required to complete the project. <br /> ■ We assume the rebar observations before concrete placements will be completed by the <br /> project representative's construction oversight manager. <br /> ■ We assume your full-time on-site construction observer will observe the test rolling for this <br /> project. <br /> ■ We assume bituminous paving will be completed in six days for this project. <br /> ■ We assume the project engineer of record will review and approve contractor's quality <br /> control submittals and test results. <br /> ■ You, or others you may designate, will provide us with current and approved plans and <br /> specifications for the project. Modification to these plans must also be sent to us so we can <br /> review their incorporation into the work. <br /> ■ We will require a minimum of 24 hours' notice for scheduling inspections for a specific time. <br /> Shorter than 24 hours' notice may impact our ability to perform the requested services, and <br /> the associated impacts will be the responsibility of others. <br /> BRAUN <br /> INTERTEC <br />
