Site Surveying. Consultant shall provide, through subcontracted professional services of a registered land surveyor subconsultant, site surveying which may include: stake/survey locations for test holes, xxxxx, test pits, test trenches; survey locations for surface features (e.g. roadways, irrigation fields, utility boxes/vaults, hydrants, utility locates by others, drainage features, hydraulic structures); survey section lines, property lines; geophysics lines, seismic lines; control datum translations; and other services to support the advancement of the project. Surveyor shall be responsible for installation of 4 survey monuments on the property. Consultant and the surveying subconsultant will prepare a work plan for this site work that includes: provisions for access when facilities are not in operation; a job health and safety analysis to plan the work such that it is done in a safe manner; and notification of land owners to ensure access to the site is available. The deliverable for this task is the raw survey data in an electronic CAD file format that can be utilized by the Consultant to develop accurate base drawings supporting detailed design.
Site Surveying. In order to control costs, we propose to use existing topographic mapping currently available to the City, and to limit the collection of new detailed data which would require on-the-ground survey, such as culvert inverts, vaults, boxes, signs, utilities, guy wires, etc., to only those areas in the vicinity of improvements comprising the selected alternative or areas which could be affected by the selected alternative. However, should the City desire the level of survey described in Task 2 throughout the entire watershed, it can be provided. Alternately, some limited surveying may be required to assess the feasibility of alternatives. These alternatives might involve rerouting of flows from Xxxxxx Canyon or diversion of Bijou Park Creek flows to the new basins east of Xxxxxx Road, or to Bijou Meadow itself, although we expect that engineering constraints with such measures are more likely associated with the location of City drainage pipes and utilities, which would require potholing, included as part of Task 5. With Chip Brejc of Insite Land Surveys who we’ve worked with on multiple projects in the City and around the lake, combined with Wildscape Engineering, NTCD and NHC’s in-house experience collecting topographic surveys of stormwater basin, wetland and riverine settings using Total Station and RTK we can easily cover all subtasks listed below.
Site Surveying. The offeror must use a professional surveyor or conduct a survey employing equivalent equipment and technique. All surveyed points must be accurate within 0.5 feet horizontally. Tops of well casings and groundwater elevations shall be surveyed to an accuracy of 0.01 feet vertically. All surveyed points must be tied to a common reference point or benchmark. Subcontracted surveying services will be reimbursed according to this RFP.
Site Surveying. Some supplemental surveying of existing stormdrain infrastructure is required to refine the 30% designs moving into 60% detail and evaluate proposed changes. For example, inlet elevations of the recently installed culvert crossings at Pioneer Trail and Xxxxxxxxxxxx Court will be surveyed in order to accurately show current conditions on the plans. Additional survey data will be collected on Spruce Avenue infrastructure to inform the Bijou School Frontage Drainage Improvement designs and on Sonora Avenue down to Xxxxxx Basin in order to inform designs for the potential revised Xxxxxx Clean Water Bypass alignment down Sonora rather than Ski Run. In order to fine tune the Bijou Park Creek hydraulic model completed during Phase 1 that was based on available LiDAR topographic data and therefore didn’t fully capture the current channel and floodplain details, we propose conducting a Total Station topographic survey of the Bijou Park creek channel and floodplain within the project limits. Wildscape and NTCD engineers will conduct the survey and consult with NHC and the landowner and key stakeholder, USDA Forest Service Lake Tahoe Basin Management Unit (LTBMU) to ensure all key channel and floodplain data is collected in sufficient detail.
