section. This section, like the drafting reproduc-tion section, falls under the direct supervision ofan EA1, depending on the number of senior EAson board and their surveying experience. The sizeand organization of the entire surveying sectionwill vary with the anticipated work load.Your job, as an EA3, along with the othercrew members in this section, is to carry out thescope of the tasks and responsibilities required ofthe surveying section. Depending on the overallmission of the battalion, typical surveying tasksmay include the following: collecting field dataand sketches for design purposes; conductingsurveys for horizontal construction (roads,airfields, aboveground and belowground utilities);conducting layout surveys for vertical construc-tion (buildings, retaining walls, waterfrontstructures, and so forth); developing level nets andlevel loops to establish vertical control; developingtriangulation networks to establish horizontalcontrol; and measuring structures in place for thepurpose of preparing as-built drawings.Versatility of the surveying section is essentialto the accomplishment of all the assigned tasks.Sometimes all crews are used on one phase of thesurveying task; at other times, crews are shuttledfrom one phase to another. Basically, for mostsurveying tasks, personnel are organized into twotypes of surveying parties: the TRANSIT PARTYand the LEVEL PARTY. They are named afterthe type of surveying instrument used.ASSIGNMENT TO MATERIALSTESTING SECTIONEAs assigned to the soils laboratory aretasked with performing tests on such items assubbase materials, aggregates, and concrete andbituminous mixes to determine if these materialsmeet specified quality requirements. You, as anEA3, may be tasked to perform some of thesetests together with a more experienced EA.Chapter 15 of this book can serve as a guide fora review of some of the tests commonly performedby an EA3.As you gain experience in testing differenttypes of materials used in construction, you maybe tasked to work with the quality control sectionof the operations department. EAs assigned to thematerial testing section work closely with the QCstaff in several areas, such as in testing materialsto ensure that their inherent character meetsminimum requirements; interpreting results oftests conducted on soil, concrete, and asphalt; andpreparing reports of the tests performed by thetesting section.CAREER DEVELOPMENTTo get ahead, you, as an EA3, must meetcertain requirements that have been prescribed foryour paygrade and rating. These requirements arereferred to as standards. Since these standardsdeal with the technical or occupational subjectmatter of each rating, they are called occupationalstandards. Occupational standards may be foundin the Advancement Handbook for Petty Officers,NAVEDTRA 71365 (fig. 16-9).In addition to the occupational standardsprescribed for each rating, there are certainmilitary requirements to be met. The militaryrequirements for advancement are discussedbriefly later in this chapter and are discussed indetail in special training manuals prepared tocover the military requirements for advancement.Figure 16-9.-Cover page of Advancement Handbook forPetty Officers (EA), NAVEDTRA 71365.16-12
