Base Mapping. The field data will be reduced and the design survey base map will be completed. A surface will be created and contours shown in the design survey. The right-of-way will be determined from existing records and found monumentation and will be shown on the design survey. A separate stand-alone design survey map will not be prepared. The CONSULTANT will conduct site visits and perform field and office verification of survey data represented in the project base map.
Base Mapping. Stantec will utilize city provided data, readily available GIS information and Lidar aerial maps to create a base map for each of the three existing parks that will be master planned – Mayfest Park, Xxx Xxxxxx Park, and Fisherman’s Park. *Note, if any of the Parks Master Plan move into the design development phase, then a topographical survey will be needed in order to create a precise set of construction documents.
Base Mapping. In order to ensure that this work can proceed without delay, as a first order of work, Consultant will apply for a City and Caltrans Encroachment Permit and for any other required permits to allow for site investigations and studies to be performed. Consultant shall conduct field visits and possible topographic surveys as needed throughout the various phases of work and approval process in order to ensure that important features are not missed and that recently installed features are identified. The field investigations and site visits will focus on notable features that will be critical to the alternative analysis and design development. Consultant will set the project control and flight crosses to develop the aerial planimetric base maps. Additionally the datum and survey control will need to verified prior to conducted topographic field surveys; Consultant shall conduct field topographic surveys, conforming to 1983 NAD (horizontal datum) and 1988 NAVD (Vertical Datum), to establish the base mapping and provide an accurate Project background. Existing documentation will be used to establish the existing right of way based on record data. The right of way will be added to the Project base sheets from the record data information.
Base Mapping. The “Project Area” of coverage for this site consists of strip mapping running along the existing levee beginning at the northwesterly termination point at the City of San Mateo, continuing southerly along the existing levee to the southwesterly termination point. The lateral limits of the strip will generally include the water, or toe of levee on the outboard side, and on the inboard side, the private property, the adjacent street and respective improvements. The mapping will also show the Mariner’s Point Golf Center on East Third Avenue. There are some additional areas of coverage as shown on Figure 1.
Base Mapping. It is assumed existing photogrammetric base mapping prepared in the PA&ED phase will be used in preparing the plans. The existing 2-dimensional photogrammetric linework will be updated to reflect the existing conditions using current high-resolution aerial imagery. Recent projects which have been constructed since the photogrammetry was prepared will be reflected in the base mapping. The photogrammetry will also be updated with supplemental topographic surveys as outlined in the scope of work below. Supplemental Topographic Surveys will be conducted to facilitate design efforts. It is assumed encroachment permits will allow access of local roads and Caltrans right of way.
Base Mapping. Information win be compiled in digital Microstation & AutoCAD format at a horizontal scale suitable for the proposed roadway and bridge design improvements.
Base Mapping. The Ramsey, Washington, and Dakota Counties aerial mapping information will be utilized to allow the design of alternative scenarios to begin immediately. We believe the quality of the information is such that the majority of detailed field survey and geotechnical investigations can be performed later in the study after selected alternatives have been determined, particularly in areas that may be many miles to the southeast down the jointly operated BNSF and/or CPR lines where siding and cross-over improvements may be identified during the study. Available Saint Xxxx GIS data, railroad valuation and right-of-way maps, and a field search for survey monuments will be used to estimate the right-of-way for the corridor within approximately one foot horizontally, (concentrating on critical areas). The project team will perform LiDAR scans of the critical areas at existing grade crossing structures, and perform select rail surveys early in Task 1.0.
Base Mapping. Prepare topographic mapping in Civil 3D 2021 at a 1” = 20’ scale, 11”x17”. Topographic features will be depicted using standard symbols. Topographic features will be shown on the design plans. Locations (X & Y coordinates) and elevations of local TBMs will be shown. Street ROW will be shown based on the CITY’s G.I.S. mapping. Water system and water service will be shown based on CITY’s G.I.S. mapping and as marked by the CITY in the field. Storm drainage systems will be referenced based on ACHD’s available G.I.S. information and field survey of visible storm drainage facilities. Roadway will be cross-sectioned at 50’ to 100’ intervals, on centerline, edge of pavement, gutter, top of curb and natural ground near ROW. Property addresses and ownership will be shown from available GIS information adjacent to the project corridor.
Base Mapping. SEI will prepare a base map of the project area using field survey collected, as-builts, CAD files provided by the City and utility information from the landfill. This base map will show existing property lines, topography, utilities and existing surface improvements. P:\Casa Grande\05480Landfill Drainage\Admin\Contract\Support Files\CONTRACT - Landfill Drainage 4-20-16.docx Task 1.3 – Construction Documents: SEI will prepare the design, specifications and construction documents for the new drainage pipe. These plans are anticipated to include:
Base Mapping. CCG will collect all information provided by the project team and produce autocad base drawings that will be shared as needed with the project team. This information may be obtained from existing hard-copy drawings, existing AutoCad drawings, field measurements from site visits, and the proposed site layout from the project architect. CCG will utilize the base mapping information to produce the bid package documents.
