Later Phase Eclipse Mill Project The CONSULTANT shall prepare a Geotechnical Work Plan Memorandum for the proposed exploration program. The work plan will be submitted to the design team and the CITY for review and approval. The work plan will detail the type, location, and extent of proposed field explorations along with logistics necessary to perform the work such as access and staging areas. The work plans will also be used for utility locating clearances and for permitting that may be necessary to access the exploration locations. We assume that any required permits or rights of entry will be provided at no cost to the CONSULTANT. 300.3.3 Conduct Geotechnical Explorations The CONSULTANT shall conduct up to two days of limited access drilling in support of the bank stabilization design along the Lowell Riverfront Trail. All geotechnical explorations will be conducted with a rubber track mounted limited access drill rig. The drilling sites will be accessed by tracking along the Lowell Riverfront Trail. Each geotechnical boring will be drilled to a depth of 20 to 30 feet or practical refusal, whichever is shallower. No geotechnical borings will be drilled within the river. Each of the above-described geotechnical explorations will be logged by a licensed geologist. All drilling spoils will be drummed and transported off site for disposal by the driller. 300.3.4 Generate Boring Logs and Assign Laboratory Testing The CONSULTANT shall prepare summary boring and perform laboratory testing to evaluate relevant physical properties of the site soils. Laboratory testing will include moisture content, grain-size distribution, and Atterberg Limits. Subtask 300.4 Geotechnical Final Design The CONSULTANT shall conduct geotechnical final design analysis in support of development of the 100 percent design for the proposed improvements. The CONSULTANT shall provide the following services under this task. 300.4.1 Evaluate Field and Laboratory Data Based on the borings and the laboratory test results on selected samples, The CONSULTANT shall generate estimates of the soil strength and other properties needed to evaluate the effects the subsurface conditions will have on the proposed improvements. 300.4.2 Develop Geologic Cross-Sections The CONSULTANT shall develop new geologic cross-sections and update already completed cross sections, as needed, for the project. These cross sections will show near surface soil conditions, will be provided in a geotechnical report, and will be used to evaluate bank stabilization methods. 300.4.3 Update Seismic Design Parameters Based on the soils encountered across the site, The CONSULTANT shall update the seismic design parameters to meet current code requirements. The design spectral acceleration parameters will then be selected in accordance with the IBC code.
