WVDP Phase 1 CSAPIn situ field-screening data collection (e.g., gross activity scans) will be conducted with dataquality expectations as specified in related task orders. This may range from horizontal ±1 m tohorizontal ±1 cm. Vertical accuracy may range from “not pertinent” to ±1 cm. Examples ofinstances in which vertical accuracy is not important are area-wide gamma surveys of existingland surfaces. Examples of instances in which vertical accuracy is important are surveys of thefloors and walls of excavations.Fixed-point data collection (e.g., soil sample, monitoring well installation, and so on) will beconducted with data quality expectations as specified in related task orders. This may range from±10 cm to ±1 mm for both vertical and horizontal coordinates.For utility, engineering designs, and as-built surveys, accuracy requirements reference USACEEM 1110-1-1005 (USACE 2007) recommendations and generally follow recognized industrystandards. Earthwork is associated with Third Order (Class II) to Fourth Order accuracy. Utilitysurveys are typically associated with Third Order (Class II) accuracy. Engineering design and asbuiltsurveys may range up to Second Order, Class II requirements, depending on the structurecomponent.9.3 Survey DocumentationFor the sake of consistency and data integration, all data sets generated that include spatialdimensions will have, at a minimum, feature coordinates provided in State Plane feet, New YorkNAD 1983. Electronic coordinate information must be provided, and may be supplied in one ofthe following formats: ASCII text, Excel, or Environmental Systems Research Institute (ESRI)shapefile. Electronic data deliverables will be organized and submitted in a fashion consistentwith survey objectives.Electronic maps, as required by task orders, will be delivered in both AutoCAD dwg and ESRIshape file formats.The WVDP maintains a set of survey monuments for the WVDP premises suitable for horizontaland vertical control. Phase 1 data collection activities that involve the collection of surveycoordinates will use these monuments as reference points and for QC purposes.Rev. 1 67
