1) Geotechnical Engineer Services 1. HWA GeoSciences, Inc.will provide geotechnical services. 2. Drill 4 borings along the proposed alignment to characterize the geotechnical conditions along the project alignment. 3. Conduct analysis to develop recommendations for the design of the pipeline and structures. 4. Provide recommended minimum distance to bridge piers for trench section. 5. Prepare a geotechnical design report summarizing the conditions encountered and the final design recommendations including dewatering recommendations and buoyancy control. Client Responsibilities 1. Provide the geotechnical engineer access to the site to conduct boring and evaluate the site conditions. 2. Client to approve geotechnical bore locations. Assumptions 1. 3 borings will be to a depth of 40 feet and one boring to a depth of 80 feet. 2. Geotechnical engineer will provide recommended bore locations with input on the alignment and structure locations provided by HDR. 3. Geotechnical borings. Deliverables 1. Draft and final geotechnical report in electronic (PDF) format. 2. Five paper copies of the final report. Task 400 — Permit Acquisition and Environmental Services Objectives City staff indicated the City would prepare the permit applications for DSO with support from HDR. Based on the selected alignment in the Predesign Phase, it was determined that wetlands would not be impacted. Consequently, no wetland delineation will be prepared. HDR Services 1. Provide assistance on an as needed basis. HDR will not perform these services unless authorized in writing by the Client. Client Responsibilities 1. Responsible for all permitting acquisition and environmental services necessary to construct the project. 2.
