City of Arden Hills <br />Proposal QTB182726 <br />August 17, 2023 <br />Page 3 <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 it will take 3 trips to complete the nuclear density gauge testing on this project, <br />assuming we can perform two tests per trip. <br />■ We understand compaction testing on aggregate base material will be performed using the <br />Dynamic Cone Penetration (DCP) method; a minimum of 2 tests will be conducted each trip <br />with 2 trips assumed. <br />■ We understand 5 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 />other and not provided by Braun Intertec. <br />■ We understand bituminous paving will be completed in 2 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 />If the work is completed at different rates than described above, this proposal should be revised. If the <br />pace of construction is different than described above, this proposal should be revised. <br />Cost and Invoicing <br />We will furnish the services described herein for an estimated fee of $11,582. Our estimated costs are <br />based on industry averages for construction production. Depending on the contractor's performance, <br />our costs may be significantly reduced or slightly higher than estimated. A tabulation showing our <br />estimated hourly and/or unit rates associated with our proposed scope of services is also attached. The <br />actual cost of our services will be based on the actual units or hours expended to meet the requirements <br />of the project documents. <br />BRAUN <br />INTERTEC <br />
