WVDP Phase 1 CSAP9.0 CIVIL SURVEYING AND COORDINATE CONTROLPhase 1 decommissioning data collection will require various levels of civil surveying support.This section identifies the various levels of civil surveying support that may be required as part ofPhase 1 activities. The information contained in this overview is based on USACE EM 1110-1-1005, Engineering and Design: Control and Topographic Surveying (USACE 2007), and onUSACE EM 1110-1-1003, NAVSTAR GPS Surveying (USACE 2003).9.1 Types of Civil SurveysThe general types of survey support potentially required by Phase 1 decommissioning activitiesgoing forward include the following:1. Reconnaissance Topographic Surveys. Reconnaissance surveys are site-mapping surveysintended to lay out general site features in support of general decision-making.Reconnaissance survey information can potentially be taken from existing aerial flyovers,hand-held differentially corrected global position system (GPS) surveys, or existingmaps. Relative feature coordinate accuracy is of importance; absolute feature coordinateaccuracy is of lesser importance. Reconnaissance surveys may be a precursor to moredetailed, accurate, and costly civil surveys. An example is a Light Detection and Ranging(LiDAR) data collection effort completed for the site in 2010.2. Detailed Topographic Surveys. Detailed surveys are the basis for detailed plans showingsite layout and facilities. Detailed topographic surveys can be completed by using a totalstation, GPS, laser scanning, plane table, and/or photogrammetric methods. In the contextof the WVDP premises, detailed surveys are also used to support environmental datacollection efforts. Detailed topographic surveys are for planning and data collectionsupport purposes and have accuracy standards that are specified suitable for the planningneeds requiring support. Accuracy standards can vary widely depending on data qualityneeds. For example, an accurate elevation measurement for a gamma reading of a soilsurface may not be necessary but, for a monitoring well, an accurate top-of-casingmeasurement is essential. A LiDAR topographic surface is available for the site based onLiDAR data collection completed in 2010.Rev. 1 65
