Da Form 2857 PDF Details

The DA Form 2857, also known as the Project Field Sheet for Micro-Chain Data Entries, plays a crucial role in military engineering and construction projects. Governed by the guidelines outlined in FM 3-34.331, with the Training and Doctrine Command (TRADOC) serving as the proponent agency, this form is instrumental in recording detailed environmental and geometric data essential for precise project planning and execution. It encompasses a wide range of data points, such as organization details, date and location specifics (including latitude, azimuth of line, and elevation), observer and recorder information, and technical measurements related to meteorological conditions and geodetic calculations. These include atmospheric pressure, temperature readings, humidity levels, instrument eccentricity, and corrections applied to ensure accuracy in elevation and distance measurements. Furthermore, the form dictates the procedure for calculating means and sums essential for determining the mean radius of curvature, slope distance, and ultimately, the geodetic distance. Such comprehensive data collection enables military organizations to execute construction projects with a high degree of accuracy, ensuring that structures are built to last under specific environmental conditions.
