What is fieldwork and field survey, In this article, we will talk about what is fieldwork and field survey?
FIELDWORK is extremely important in all types of studies. To become a skilled surveyor, you must spend a certain amount of time in the field to gain the necessary knowledge. Studying this training manual will allow you to understand the basic theory of surveying, its instruments and practices, and survey methods. However, a high level of competence in the actual study, as in other professions, is highly dependent on the duration, level, and variety of your actual experience.
You must develop the practice of studying the problem in detail before entering the field. You must know exactly what to do; how to do it; why you prefer a particular approach over other possible solutions; and what instruments and materials you need to complete the project.
You must develop RISK SPEED and CONSISTENCY in all your fieldwork. This means that you should practice handling the instruments, monitoring and keeping field notes and planning systematic movements.
It is also important that you use RIGHT. You should not do anything right without proof. The decision should, as far as possible, differ from the original method used in the measurement. The accuracy of the measurement should be consistent with the appropriate level for the specific purpose of the study.
Fieldwork also includes modifying the instruments and taking care of field equipment. Do not attempt to change an instrument unless you understand the operation or functions of its parts. Changing instruments in the early stages of your career requires a close look from a major EA.
Factors Influencing Fieldwork
The surveyor must always be vigilant about the various situations that have occurred in the field. Physical factors, such as TERRAIN AND INITIAL CONCLUSIONS, affect each field study at different stages. Swamps and high floodplains underwater can impede tapping surveys. Views over open water or unbroken fields of flat ground create measurement uncertainty using microwave equipment. The speed of the incoming light waves measurements is reduced in bright sunlight. In general, the acknowledgment predetermines the conditions and alerts the survey part about the best method to use and the expected progress rate.
The STATUS OF THE TECHNICAL PREPARATION OF THE STAFF is another factor that affects fieldwork. As you gain experience working on a variety of survey tools, you can reduce study time and avoid mistakes that require a new study.
THE PURPOSE AND TYPE OF SURVEY are primary factors in determining accuracy requirements. First-order triangulation, which becomes the basis or “control” of future studies, is performed with high-precision standards. At the other extreme, cuts and fills for a road survey have much lower grade precision standards.

In some construction studies, normally inaccessible distances must be calculated. The distance is calculated by trigonometry, using the angles and the only distance that can be measured. Measurements must be made with a high degree of precision to maintain precision over the calculated distance.
Field Survey Groups
The size of a field survey group depends on the survey requirements, the equipment available, the inspection method, and the number of personnel required to perform the various functions. Four common field study groups commonly used in Seabees are briefly described in this category: Stage Party, Shift Party, Stadium Party, and Airplane Party.
There are two in the smaller level party: an instrumentalist and a rodent. This type of organization requires the instrument to be a note-taker. The party may need another recorder and one or more additional rodents to improve the effectiveness of the various stages. The addition of the rods eliminates waiting times while a person moves from one point to another, and an additional recording device allows the instructor to take readings. as soon as the rodents are in place.
When grading operations are run in conjunction with other control checks, the grading party can be organized as part of a party where employees take on dual responsibilities as workload requires and as designated by the party leader.
A transfer group consists of at least three people: an instrumentalist, a key ring, and a party leader. The group leader is usually a note taker and can function as a sub-chain, or it can have an additional sub-chain. The instrument operates the movement; the head chain measures horizontal distances, and the party leader conducts the investigation and saves the notes.
Party at Home
A party in residence must consist of three people: an instrumentalist, a notes manager, and a bar manager. However, two rods should be used if there are large distances between the observed points so that one can advance to a new point, while the other supports the rod at a point being observed. The person responsible for the note records the data requested by the operator and makes the required sketches.
Aircraft Table Party
The airplane table party consists of three people: a surveyor or airplane table operator, a man on his knees, and a computer. The surveyor is the leader of the group that installs, levels, and orientates the plane table; takes the necessary readings to determine horizontal distances and elevations; Traces the details on the airplane chart sheet as the work progresses; and, and leads the other party members.
The rodman carries a stadium bar and holds it vertically at detail points and critical points on the terrain in the map layout. The surveyor should direct an inexperienced rod technician to each point where the rod will be placed.
A rod expert will streamline the group’s work by selecting the proper rod positions and sometimes returning to the plane table to draw special details that you may have noticed.
