Survey Limit Boundaries The survey is anticipated to require up to two (2) 10-hour work days in the field for a two-person survey firm crew to complete the survey.The river survey at the outfall location is anticipated to require one (1) 8-hour day that includes mob and de-mob of the small boat that will be required to complete the river cross- sections and outfall survey.The river survey will be performed concurrently with the land survey effort for maximum efficiency. The survey will include incorporating the geotechnical boreholes, (as documented in the HWA Geosciences Inc. report titled Final Geotechnical Data Report, Group 3-Public Amenities Riverfront Development, November 2, 2011) and other surface features in the vicinity of the project area. (It is understood that there may be some landfill gas vents in the project area which should be considered for this project work; City staff will help identify these vents to the surveys for inclusion in the base map.) Service Provider shall prepare a 1"=20"topographic base map of the project limits, including staging area and routes into the site.The base map will include, but not be limited to, access roads, key surface features, signs,trees of significance,ditches, culverts, buried pipes, catch basins, utility poles, outfall SR08 terminus, and other surface and subsurface features within the survey limits. Utility locates services will identify applicable subsurface features prior to the survey. Specific field investigation and surveying activities include: • Field Investigation:The Service Provider's Project Manager, Design Manager,Structural Engineer and SR08 Outfall Pipe Rehabilitation Design Lead (or designee) shall conduct a field investigation to evaluate the project site.The investigation will include a very broad-brush visual inspection of the SR08 vault wall.The City will assist with opening the SR08 structure for inspection. Note that no field inspection of the SR08 outfall in the river will be conducted during this phase of the project. Upon review of the City- provided data (Subtask 7.4),the Service Provider may recommend that this investigation be conducted during Phase 2, Design and Bid Services. • Utility Locating: Utility locating services will be arranged to paint the surface and identify utilities located within the project area for use by the survey firm. • Surveying:The qualified surveying firm shall conduct a field survey to develop a topographical map and 41P 4 G E
