Bolton & Menk, Inc. Proposal QTB175606 April 4, 2023 Page 6 We will determine the actual laboratory testing for the project depending on the encountered subsurface conditions. If we identify a laboratory testing program that exceeds the budget included in this proposal but provides additional value to the project, we will request authorization for the additional fees through a Change Order. Engineering Analyses We will use data obtained from the subsurface exploration and laboratory tests to evaluate the subsurface profile and groundwater conditions, and to perform engineering analyses related to structure and pavement design and performance. Geotechnical Report We will prepare a report including: ■ A sketch showing the exploration locations. ■ Logs of the borings describing the materials encountered and presenting the results of our groundwater measurements and laboratory tests. ■ A summary of the subsurface profile and groundwater conditions. ■ Discussion identifying the subsurface conditions that will impact design and construction. ■ Discussion regarding the reuse of on-site materials during construction. ■ Recommendations for preparing structure and pavement subgrades, and the selection, placement and compaction of fill. ■ Recommendations of structure bearing capacities and assumed R-value for use in pavement section design. ■ Recommendations for the design and construction of pavements and stormwater improvements. We will only submit an electronic copy of our report to you unless you request otherwise.At your request,we can also send the report to additional project team members. Schedule Environmental Scope We anticipate the draft Phase I ESA report will be completed within 2 to 3 weeks from the date of your written authorization.The Phase I ESA report will remain in draft status until we are notified by you to proceed with issuance of the final Phase I ESA report.
