SURVEY MARKERS AND MONUMENTATION
|Publication Date:||1 March 2012|
This manual provides naming criteria, standard installation procedures, and associated surveying accuracies for horizontal and vertical control and boundary survey markers and monumentation for standard USACE monuments. It should be used as a guide in planning surveys and marker and/or monument installation and identification. The type of marker and/or monument selected for each survey should be tailored to meet the minimum accuracy requirements for the individual project. However, selection should be done within the stated criteria where feasible and practicable, using the guidance provided herein. The accuracy classification of each survey monument is dependent upon the site foundation conditions and the type of monument installation used. All standard Corps monuments as defined herein shall be installed in accordance with this manual. The term "marks" and "control points" shall be used throughout this manual when referring to both permanent monuments and temporary markers used as vertical and horizontal control. The term "bench mark" refers to a mark used solely for vertical control. The term "bench mark" refers to a mark whose elevation is known. Monuments and markers are further defined in paragraphs 1-8 and 1-9.
Purpose. This manual establishes criteria and presents guidance on monumentation installation and documentation for all types of surveys required during the various stages of US Army Corps of Engineers (USACE) civil and military projects. The manual is intended to be a guide; however, when the standard USACE monuments are used, they shall be selected and constructed as defined in this manual.
