This unique electronic book on CD-ROM has a complete reproduction of the U.S. Army Field Manual, Construction Surveying, FM 5-233 (238 pages). In addition, as a bonus, there are reproductions of over 100 vital U.S. Army Field Manuals covering such topics as combat, arms, operations, training, support, and dozens of special topics! This manual is a guide for engineering personnel conducting surveys in support of military construction. In addition to mathematical considerations, this manual offers a comprehensive analysis of problems which are typical in military surveying. It may be used for both training and reference. In support of construction activities, the surveyor obtains the reconnaissance and preliminary data which are necessary at the planning stage. During the construction phase, the surveyor supports the effort as needed. Typical duties of the construction surveyor include: Determining distances, areas, and angles. Establishing reference points for both horizontal and vertical control. Setting stakes or otherwise marking lines, grades, and principal points. Determining profiles of the ground along given lines (centerlines and/or crosssection lines) to provide data for cuts, fills, and earthwork volumes. Preparing large-scale topographic maps using plane table or transit-stadia data to provide information for drainage and site design. Laying out structures, culverts, and bridge lines. Determining the vertical and horizontal placement of utilities. The precision of measurements varies with the type of work and the purpose of a survey. Location surveys require more accuracy than reconnaissance surveys, and the erection of structural steel requires greater precision in measurement than the initial grading of a roadbed. The officer or NCO in charge of a project usually determines the degree of accuracy. The surveyor makes a practical analysis and chooses appropriate methods and procedures for each type of measurement. The surveyor must consider the allowable time, the tactical situation, the capabilities of construction forces, and the current conditions. The best surveyor is the one who runs a survey to the order of precision which is required by the job with a minimum of time, not the one who insists on extreme precision at all times. Surveyors must always be on the alert for probable cumulative or systematic errors, which could be the result of maladjustment or calibration of equipment or error-producing practices. Laying out the foundations for certain types of machinery and establishing angular limits for fire on training ranges are examples of conditions which might demand a high degree of precision from the surveyor.
