• Laboratory Testing — Representative samples from the subsurface exploration will be tested for index and strength properties to provide a basis for determining retaining wall design criteria. 3.1.3 Geotechnical analysis and reporting including conclusions and design recommendations and technical report. • Conclusions and Design Recommendations — CSA will analyse field and laboratory data to formulate geotechnical conclusions and retaining wall design criteria, including: suitable retaining wall foundation type and depth for the embedment; site grading and drainage recommendatiQns; foundation design criteria; and estimated settlement behaviour of the wall. • Technical Report — CSA will prepare a geotechnical report and appropriate illustrations (based on a topographic base map provided to CSA) to summarize the findings of the investigation. The report will contain an assessment of observed site conditions, and provide geotechnical engineering conclusions and recommendations for the proposed retaining wall. Four (4) copies of the report and associated illustrations will be submitted. 3.2 Consultant will make a site visit and take hand measurements to determine approximate limits and extent of site work. This above ground visual inspection will be used in conjunction with the topographic survey and geotechnical investigations performed to gain a good understanding of the site conditions, restrictions and opportunities for design. Any as-built or topographic maps provided from the City will also build on this effort. 3.3 75% Civil Design 3.3.1 Consultant will coordinate with utility companies for minor relocations of their facilities due to project impacts, but it is assumed that major utility relocations will not be necessary for the scope of the project. If particularly large or complicated utilities are encountered that must be relocated to accommodate project needs and they require extensive coordination efforts with utility companies, these would need to be handled through a separate amendment process. The drainage plan for the proposed retaining wall improvements will also be prepared under this task, including valley gutter and drainage inlet systems both behind/on top of the wall and in front/at the base of the wall. Modifications or connections to the existing drainage system will be included in this effort, including construction details and drainage profiles as necessary. 3.3.2 Layout and grading plans will be prepared for the proposed retaining wall including associated roadway widening and drainage improvements. Typical cross sections of the wall and roadway will also be prepared under this task. REV:02-21-14 VR Page 11 of 17 ATTY/AGR.2014.019/Mark Thomas&Company, Inc.
