conditions. This will include an evaluation of the effects of weather and/or <br />construction equipment on site soils. <br />• Pond Construction — Recommendations for earthwork and the design associated <br />with the detention ponds. This will include recommendations for a pond liner and <br />accommodations for groundwater, if necessary. <br />• Trenching — Conclusions and recommendations for conventional trenching <br />techniques including the following: <br />A. Geotechnical parameters for trench shoring design including lateral <br />pressures, and partial shoring considerations; <br />B. Excavation and temporary slope considerations; <br />C. Pipe support including bedding and backfilling; and <br />D. Construction dewatering considerations including depth to groundwater <br />encountered during drilling and estimated permeability coefficients based <br />on laboratory sieve analyses. <br />E. Subgrade conditions that might necessitate overexcavation and placement <br />of foundation material and geotextiles prior to street restoration. <br />• Erosion Control — Provide recommendations for erosion control during <br />construction. <br />• Documentation — Prepare a written report presenting conclusions and <br />recommendations along with supporting boring logs, laboratory data, and other <br />appropriate figures. Present draft report for consultant team and City review and <br />comment. <br />Assumptions: <br />1. City to provide right-of-way use permit and City owned facility locates for <br />exploration program. One -call utility locator will be contacted for all other <br />utilities. <br />2. City to review proposed boring locations and exploration plan. <br />3. City to provide available existing geoteclu-iical investigations from the project <br />vicinity. <br />Deliverable: <br />1. Two bound copies and one PDF file of the draft and fugal Geotechnical Report. <br />Task 5 — Hydraulic Modeling <br />This task will provide hydraulic modeling for design of the proposed separate stormwater <br />drainage network, demonstrate elimination of surcharging in the existing sewer collection <br />system and to furnish flow information needed to design the Stormwater detention pond <br />system. Anticipated elements of this task will include: <br />5. 1 Data Req 11€est au, d Ira orinc aion Gatherin a Work under this subtask includes <br />gathering and reviewing all relevant data to this task.
