An Introduction to Accuracy Standards for Land Surveys
This online engineering course sets forth accuracy standards and other related criteria that are recommended for use in large scale site plan topographic surveys for engineering and construction purposes. These standards relate to surveys performed to locate, align, and stake out construction for projects, e.g., buildings, utilities, roadways, runways, flood control and navigation projects, etc.
In many cases, these engineering surveys are performed to provide the base horizontal and vertical control used for area mapping, GIS development, preliminary planning studies, detailed site plan drawings for construction plans, construction measurement and payment, preparing as-built drawings, installation master planning mapping, future maintenance and repair activities, and other products. Most engineering surveying standards currently used are based on local practice, or may be contained in state minimum technical standards.
This 3 PDH online course is intended for civil engineers and professional land surveyors interested in learning about accuracy standards for land surveys.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Learning about general surveying and mapping specifications. for construction plans, maps, facility plans, and CADD/GIS databases
- Learning about published surveying and mapping accuracy standards, such as the American Society for Photogrammetry and Remote Sensing (ASPRS), the American Society of Civil Engineers (ASCE), the American Congress on Surveying and Mapping (ACSM), and the American Land Title Association (ALTA)
- Learning about quality control (QC) practices for contracted surveying and mapping work to be performed by a contractor
- Understanding why, when practical, feasible, or applicable, projects should be adequately referenced to nationwide or worldwide coordinate systems directly derived from, or indirectly connected to, GPS satellite observations
- Understanding how engineering and construction surveys are normally specified and classified based on the horizontal (linear) point closure ratio or a vertical elevation difference closure standard
- Learning about construction survey procedural and accuracy specifications developed by recognized industry and local practice
