Grand Avenue Utilities Replacement,UP No. 3711 <br /> June 30, 2020 Project No. 170095 <br /> Soil samples will be returned to our office for further examination, and selected samples will be <br /> submitted for geotechnical laboratory testing to determine index and engineering properties. Tests <br /> may include moisture content, grain size distribution, and moisture-density. <br /> Task 4-Deliverables and Geotechnical Design <br /> We will revise our 2017 draft report with the supplemental data and submit Draft and Final <br /> geotechnical engineering reports containing the results of our services, including the following <br /> information: <br /> • A Site Plan showing the explorations locations with assigned stationing <br /> • Exploration logs and a summary table of pertinent data <br /> • Laboratory test results <br /> • Groundwater considerations <br /> • Construction considerations: <br /> — Structural fill material and preparation <br /> — Subgrade preparation <br /> — Wet weather considerations <br /> — Pipe trench excavation, stability and shoring <br /> — Pipe zone bedding, backfill requirements and suitability of soil re-use <br /> — Temporary erosion control <br /> • Pavement section design and restoration <br /> We will address any review comments or questions on the Draft and issue a Final geotechnical <br /> engineering report, sealed by a licensed professional engineer from Aspect. <br /> Cost Estimate <br /> This project will be completed on a time and materials not to exceed of$22,200 that includes the <br /> requested $5,000 contingency. A breakdown of our costs is presented in the attached Cost Estimate <br /> Worksheet along with a copy of Aspect's WSDOT-approved overhead rate(197.97%) letter. <br /> Task Fee Estimate <br /> Task 1 —Literature Review $800 <br /> Task 2—Exploration Planning and Permitting <br /> Preliminary Plan and Site Visit 800 <br /> Exploration Plan, Permitting, Coordination 1,000 <br /> Task 3—Exploration Program <br /> Subcontractor Fee(Coring, Drilling, Traffic Control) 7,500 <br /> Aspect Labor 2,100 <br /> Expenses (mileage and equipment) 200 <br /> Soil Testing 1,000 <br /> Task 4—Deliverables and Geotechnical Design <br /> Draft Geotechnical Engineering Report 2,800 <br /> Final Geotechnical Engineering Report 1,000 <br /> Contingency $5,000 <br /> Total (T&M) $22,200 <br /> Page 3 <br />
